Characters of Glee
Glee is a musical comedy-drama television series that airs on Fox in the United States. It focuses on the high school glee club New Directions competing on the show choir competition circuit, while its members deal with relationships, sexuality and social issues. The initial main cast encompassed club director and Spanish teacher Will Schuester (Matthew Morrison), cheerleading coach Sue Sylvester (Jane Lynch), guidance counselor Emma Pillsbury (Jayma Mays), Will's wife Terri (Jessalyn Gilsig), and eight club members played by Dianna Agron, Chris Colfer, Kevin McHale, Lea Michele, Cory Monteith, Amber Riley, Mark Salling and Jenna Ushkowitz. For the second season, formerly recurring cast members Mike O'Malley, Heather Morris and Naya Rivera were promoted to the main cast. In the third season the main cast remained at fifteen, with Harry Shum, Jr. and Darren Criss promoted to it, while Gilsig and O'Malley no longer received star billing. The fourth season began with fourteen in the main cast: Chord Overstreet was promoted, and Mays and Agron were removed and demoted to recurring cast.
The series has many supporting characters, including faculty members, students and relatives of the glee club members. Broadway stars including Idina Menzel, John Lloyd Young, Jonathan Groff, and Kristin Chenoweth have been featured in guest roles. A number of the principal actors were cast directly from Broadway, while those without theatrical backgrounds were required to demonstrate singing and dancing as well as acting ability.
In casting Glee, series creator Ryan Murphy sought out actors who could identify with the rush of starring in theatrical roles. Instead of using traditional network casting calls, Murphy spent three months on Broadway, where he found Matthew Morrison (Will Schuester), who had previously starred on stage in Hairspray and The Light in the Piazza, Lea Michele (Rachel Berry), who starred in Spring Awakening, and Jenna Ushkowitz (Tina Cohen-Chang), from the Broadway revival of The King and I. The role of Rachel was written specifically for Michele.
Chris Colfer (Kurt Hummel) had originally auditioned to play Artie Abrams. Although Colfer had no previous professional experience, Murphy was so impressed by Colfer's performance that the role of Kurt Hummel, named after the character Kurt from The Sound of Music, was created for him.
Auditioning actors with no theatrical experience were required to demonstrate their ability to sing and dance. Jayma Mays (Emma Pillsbury) auditioned with the song "Touch-a, Touch-a, Touch-a, Touch Me" from The Rocky Horror Show, while Cory Monteith (Finn Hudson) initially submitted a tape of himself acting only, and was requested to submit a second, musical tape, in which he sang "a cheesy, '80s music-video-style version" of REO Speedwagon's "Can't Fight This Feeling". Cory Monteith has deemed his casting "spot on" as his lack of formal training is reflected in the abilities of his character, Finn Hudson.
Kevin McHale (Artie Abrams) came from a boy-band background, having previously been part of the group Not Like Them. He auditioned with the song "Let It Be" and tested alongside Colfer and Ushkowitz. McHale explained that the diversity of the cast's backgrounds reflects the range of different musical styles within the show itself: "It's a mix of everything: classic rock, current stuff, R&B. Even the musical theater stuff is switched up. You won't always recognize it." Jane Lynch was originally intended to have a recurring role in the show, but became a series regular when a Damon Wayans pilot she was working on for ABC fell through.
Dianna Agron (Quinn Fabray) was the last primary actor to be cast, having won the role only days before the pilot began filming. Agron auditioned for Glee coming from a background in dancing and acting. Agron said in a 2009 interview pertaining to her casting session: "I nearly bailed on my audition for the show. I was so nervous". With her wholesome good looks, Agron certainly looked the part, but the producers wondered if she appeared too innocent. Agron said in an interview: "They told me to come back with straight hair and to dress sexier. Later that week, I started work." Agron auditioned with Frank Sinatra's "Fly Me to the Moon". The Glee producers said "we really lucked out in finding Agron to play Quinn".
Main characters 
Artie Abrams 
Artie Abrams (Kevin McHale) is a guitarist and paraplegic manual wheelchair user. McHale described Artie as a "nerd" who loves the glee club wholeheartedly and uses it as a form of escapism. Artie uses a wheelchair due to a spinal cord injury he received in a car crash at the age of eight. During the first season, he begins to accept his disability and the fact he will never achieve his dream of becoming a dancer. In the first season, he has a relationship with fellow New Directions member Tina Cohen-Chang, who breaks up with him at the beginning of the second season. Artie then loses his virginity to cheerleader Brittany Pierce, and with encouragement from his former bully, Puck, they begin dating. The two remain a couple for most of the season before breaking up. In the third season, Artie, then a junior, directs the school musical and a television special featuring the glee club for the local PBS station.
McHale joined Glee from a dance background, and found it challenging to adapt to using a wheelchair, but was able to utilize his dancing ability in the episode "Dream On", in which Artie dances in a shopping mall during a fantasy flash mob sequence. The episode "Wheels", which places focus on Artie and his disability, drew criticism from a committee of performers with disabilities, who felt that casting an able-bodied actor to play a disabled student was inappropriate. Glee's executive producer Brad Falchuk responded that while he understood the concern and frustration of disability advocates, McHale had the singing and acting ability, talent and charisma required for the role.
Blaine Anderson 
Blaine Devon Anderson (Darren Criss) is introduced as an openly gay student at Dalton Academy and a member of The Warblers, a Sectionals and Regionals rival of New Directions. While Blaine was initially a recurring character, Criss was promoted to the main cast for the third season. The character is a love interest for Kurt, though in the episode "Blame It on the Alcohol", he and Rachel have a brief fling, resulting in Blaine reasserting his identity as gay. Murphy stated, "Darren has a major, major arc... He sort of becomes Kurt's mentor and then maybe love—he had to leave his own school because of bullying and goes to an all-boys academy and finds acceptance because that school has a no-bullying, zero-tolerance policy." Blaine becomes a role model for Kurt, who develops a crush on him. During "Original Song", Blaine realizes he reciprocates Kurt's feeling, and they kiss. At the beginning of season three, Blaine decides to transfer to McKinley to be with Kurt, and joins New Directions. The two have their first sexual experience in the episode "The First Time". Blaine is injured during a confrontation between New Directions and the Warblers, and has eye surgery to repair the damage. His relationship with Kurt is later strained by Kurt's eagerness to leave for New York after graduation, which would separate the two at least until Blaine graduated the following year, but the two patch things up, and are still a couple at the end of the school year.
At the beginning of his senior year, Blaine becomes the lead singer of New Directions and successfully prompts Kurt to follow his New York City dreams. Blaine successfully runs for senior class president. Kurt inadvertently pulls away from Blaine due to his Vogue.com internship; distraught, Blaine cheats on Kurt. After confessing to Kurt of his infidelity, Kurt severs all ties. Hunter Clarington (Nolan Gerard Funk), the new captain of the Dalton Academy Warblers, attempts to convince Blaine to return to the Warbler. Blaine becomes conflicted, but Sam Evans (Chord Overstreet) ultimately convinces him that, despite having done a bad thing, Blaine is still a good person and an important member of New Directions. Kurt begins to mend their relationship in "Thanksgiving" and they spend Christmas together in New York City.
Rachel Berry 
Rachel Barbra Berry (Lea Michele) is the lead character and is a "strong, driven" member of the glee club, who is misunderstood by her peers. Michele took the role in Glee because of Rachel's characterization, explaining: "Not only is she a singer, but she has so much heart—I think it's what we need on TV." Michele described the first thirteen episodes of the series as: "Rachel's journey of finding herself within the glee club", explaining that: "She's learning how to be a team player and work within this group."
Rachel has an on-off relationship with Finn throughout the series. She briefly goes out with his best friend Puck, and later dates Jesse St. James (Jonathan Groff), the lead singer of rival glee club Vocal Adrenaline, who ultimately betrays her in favor of his club. Rachel discovers that Vocal Adrenaline coach Shelby Corcoran (Idina Menzel) is her birth mother—Rachel has two gay dads—but the two fail to forge a relationship. At the end of season one, Finn professes his love for her. They date over the summer and for several episodes in season two, but break up when Rachel makes out with Puck in revenge for Finn having lied about losing his virginity to Santana in season one. At the end of season two, they begin a renewed relationship after Nationals in New York, though Rachel warns Finn she will be returning to New York for good after she graduates. In the beginning of the third season, Rachel plays Maria in the school's production of West Side Story, and she and Finn have sex for the first time. In the new year, Finn asks Rachel to marry him, and she accepts. Although she blows her audition for a New York dramatic arts college, NYADA, her Nationals performance in Chicago acts as a redo, and she is ultimately accepted, but Finn is rejected from his New York school. After graduation, on the day of their wedding, Finn drives her to the train station, and announces she will be going to New York without him.
While at NYADA, Rachel struggles to impress her dance teacher, Cassie July, and embarks on a new romance with upperclassman, Brody Weston. However, after persistent speculation from Santana, the two break up as Rachel learns that Brody was a male escort and rediscovers her feelings for previous love, Finn.
Mike Chang 
Michael Robert "Mike" Chang, Jr. (Harry Shum, Jr.) is a football player and dancer who joins New Directions in the episode "Preggers". Shum stated that Mike is shy, and that he joins the glee club despite it being "social suicide" as "he has finally found a place where he can express himself and feel accepted". Initially a supporting character with no storylines of his own, Mike was slowly developed by the series writers. In the final episode of season one, Mike says that before New Directions, "I was afraid to dance outside my room." In season two he begins dating Tina, and gives his first lead musical performance duetting with her on "Sing!" from A Chorus Line. He is subsequently selected to perform a dance routine with Brittany for Sectionals in "Special Education". He performs the show's first solo dance routine in "A Night of Neglect". Mike states that he is a senior in the season three premiere, "The Purple Piano Project", and Shum as Mike was promoted to the main cast for the show's third season. Mike tries out for the school musical, West Side Story, against his father's wishes, and is briefly disowned by him, though his father later comes to understand Mike's desire to become a dancer and supports his decision to go to college for dance. Mike is given a scholarship to attend the Joffrey Ballet school in Chicago, and graduates at the end of the season. He and Tina are still a couple at the end of the year, but she breaks up with him over the summer.
Tina Cohen-Chang 
Tina Cohen-Chang (Jenna Ushkowitz) auditions for the glee club with the song "I Kissed a Girl" by Katy Perry. She initially dresses in school-girl like clothing and gothic style clothing. She goes on a date with Artie, and confesses to him that she has been faking a speech impediment since the sixth grade, explaining that she wanted to drive people away, but now that she's a part of the glee club, she no longer wants that. Their relationship continues through the end of that first year. Tina and Mike Chang are counselors at Asian Camp over the summer, and they fall for each other; Tina formally breaks off with Artie at the beginning of the second season, and she and Mike are still in love when the school year ends, the only relationship in the glee club to survive the entire school year, and the longest unbroken relationship between the members since the club was formed. In the third season, her junior year and his senior year, she helps Mike when he decides to try out for the school musical and then to apply to dance school, and tells Rachel and the other girls that she had sex for the first time with Mike over the summer, losing her virginity. Tina breaks up with Mike over the summer after he graduates. She develops a brief obsessive crush on Blaine, but it is later diminished and turns into a close friendship.
Sam Evans 
Sam Evans (Chord Overstreet) is a transfer student who joins the football team in season two. Encouraged by Finn to audition for New Directions, he joins the males of the group in a performance of "Billionaire", the same song with which Overstreet studio tested for Glee. Despite some trepidation about the effect it may have on his social status, Sam eventually joins the glee club. With the connivance of Finn and Rachel, he and Quinn are partnered for, and win, a duet competition within the group, after which their victory dinner turns into a first date; the victory later nets them a lead performance at sectionals. He begins a relationship with Quinn Fabray (Agron) in "Duets" but she is later unfaithful to him, rekindling her romance with Finn. In the episode "Comeback", Sam makes a last-ditch attempt to win her back, but ends the relationship after finding out from Santana that Quinn cheated on him with Finn. At some point after going to junior prom together, Sam and Mercedes start to secretly date. His family moves to Kentucky over the summer, but Finn and Rachel convince him to come back to New Directions late that fall in time to compete in Sectionals. Although Mercedes has a new boyfriend, he wants to get her back. In season four, he develops friendships with Blaine and Brittany, the latter of which becomes a romantic relationship.
Following Overstreet's casting, media speculation suggested Sam might have been created as a boyfriend for Kurt. Overstreet later confirmed this, but stated that his storyline had been adjusted to pair Sam with Quinn, as a result of the chemistry the producers detected between himself and Agron. Overstreet left the show when his option for being a series regular in season three was not picked up, but he returned as Sam in the eighth episode of the third season for a multi-episode arc. On October 24, 2011, Murphy officially announced that Sam would be returning as a recurring character, "just in time for Sectionals". Overstreet was promoted to the main cast in the fourth season.
Quinn Fabray 
Quinn Fabray (Dianna Agron), is introduced as Finn's girlfriend, head of the cheerleading squad and president of the celibacy club. She was described by Agron as Rachel's enemy, and "terrible, the meanest girl." Quinn joins the glee club because Finn is a member, and because cheerleading coach Sue Sylvester wants her to bring the club down from the inside. She oscillates between desiring acceptance, which she finds in New Directions, and desiring popularity, which she finds on the Cheerios. She reveals to Finn that she is pregnant and tells him that the baby is his, although the real father is Finn's best friend Puck. Eventually the deception is revealed, and Quinn decides to give the baby away. In the season finale, Quinn gives birth to her daughter, whom Puck names Beth. The baby is adopted by Vocal Adrenaline coach Shelby Corcoran (Idina Menzel), Rachel’s birth mother.
At the beginning of the second season, Quinn rejoins the Cheerios and again becomes the captain, regaining her popularity, though later in the season she quits to remain faithful to New Directions. She begins a relationship with Sam Evans (Chord Overstreet) in "Duets" but is later unfaithful to him, rekindling her romance with Finn. In the episode "Comeback", Sam makes a last-ditch attempt to win her back, but ends the relationship after finding out from Santana that Quinn cheated on him with Finn. Quinn and Finn get back together, though eventually Finn realizes his true feelings for Rachel, and breaks up with Quinn. It is also revealed that Quinn's real name is Lucy Quinn Fabray and she used to be bullied for being fat, and eventually decided to have a nose job.
During the summer between seasons two and three, Quinn undergoes a transformation: she dyes her hair, gets a tattoo and a nose ring, and takes to smoking behind the bleachers with her new clique the Skanks. However, in "I Am Unicorn", when Shelby Corcoran joins the McKinley High faculty and talks to Quinn about being involved in Beth's life, Quinn pretends to clean up her act and returns to New Directions. What she intends is not to merely be in Beth's life, but to get full custody of her daughter. Her attempts to prove Shelby an unfit mother fail; eventually, she realizes with Rachel's help that Shelby is Beth's true mother, and stops trying to reclaim Beth. Shelby resigns and leaves McKinley. Quinn subsequently receives a college acceptance letter from Yale. At the end of "On My Way", while driving to Finn and Rachel's wedding, her car is struck by a truck and she suffers a spinal injury that requires her to use a wheelchair for many weeks. She is eventually able to walk again, and even to dance in performance with the glee club.
She makes brief appearances in season four, forming a friendship with Kitty, visits Rachel with Santana to convince her not to do a nude scene, and hooking up with Santana at Will and Emma's wedding.
Finn Hudson 
Finn Hudson (Cory Monteith) is star quarterback who is overheard singing in the mens shower by Will Schuester and subsequently blackmailed to try out for the Glee club when Will plants drugs in his locker. As quarterback of the school's football team, and arguably one of the most popular students at McKinley, it is Finn who risks alienation by his friends to join the glee club. He is dating cheerleader Quinn, but is conflicted by his growing feelings for Rachel. Quinn later tells Finn she is pregnant and he is the father. Finn intends to support her, unaware the father is actually his best friend Puck. He has a premature ejaculation problem, which causes him to believe he is the father of Quinn's baby despite the fact that they have never had sex. When he discovers the truth, he breaks up with Quinn and turns to pursuing Rachel. In the season one finale, he professes his love for her before New Directions performs at Regionals, and the second season finds Finn and Rachel a couple. A flurry of infidelities forces the two apart, though Finn succeeds in winning Rachel back in the season two finale despite Rachel warning him that upon graduation she will be leaving Ohio for good. In the third season, Finn proposes to Rachel and she eventually accepts. They graduate in season finale, but while Rachel gets into a New York school, Finn does not; on their wedding day, he instead sends her off to New York without him to fulfill her dreams, and Finn enlists in the army to follow his late father's footsteps. He does not stay in touch with Rachel or Kurt for several months. He reappears unexpectedly that fall during the show's fourth season, while Rachel is attending NYADA, after he has been given an early discharge from the army. He feels that he doesn't belong in her world in New York, returns to Lima without telling her. She then breaks up with him. In Lima, Finn is working at Burt's tire shop again, and Artie enlists his help there to co-direct the school musical, Grease, which had been Finn's suggestion. When Rachel comes to see the musical in "Glease", their reunion does not go well, and they agree to refrain from contact when Rachel visits Lima in the future. Will takes a leave of absence to be a member of a blue-ribbon panel in Washington, DC, so in "Dynamic Duets", Finn has become interim glee club director. While he has a rocky start in the position, they come to accept him as their leader. Will's absence leads him to have a close friendship with Emma Pillsbury, gradually resulting in them kissing. The guilt of this event causes her to stand Will up at the altar, eventually leading him and Will to end their friendship. Upon convincing by Marley Rose, he enrolls in college to receive a teaching degree. He is later seen in New York after being told that Brody is an escort by Santana, which results in him physically attacking Brody warning him to "stay away from his future wife."
Burt Hummel 
Burt Hummel (Mike O'Malley) is Kurt's father to whom Kurt comes out in the episode "Preggers". Both James Poniewozik for Time and Tim Stack for Entertainment Weekly praised O'Malley's performance in the storyline, with Poniewozik additionally commenting: "the fact that Dad [...] ends up not being the boor we think he's going to be is one of the first signs that Glee is growing up as a series, that having established a world of primary-color stereotypes, it's now willing to subvert those expectations." Initially a recurring cast member, O'Malley was promoted to a series regular for season two, though he reverted to the recurring cast for the third and fourth seasons.
During the first season, Kurt acts as a matchmaker for Burt and Carole Hudson (Romy Rosemont), Finn's widowed mother. He feels left out when Burt and Finn bond, but Burt reassures him that he will always come first. Burt and Carole briefly live together, until he throws Finn out for using a homophobic slur against Kurt. In season two, Burt has a heart attack but recovers. He and Carole marry, using their vows to express pride in their sons. In the third season, Burt wages a write-in campaign for congress against leading candidate Sue Sylvester, and wins. He divides his time between Washington and Lima, acts as a father for both Kurt and Finn, and is there with Carole for both the Regionals show choir competition and the graduation of their two sons. He sends Kurt to New York in the fall, and when he visits at Christmas, reveals that he has recently been treated for prostate cancer, and that it appears to have been caught in time.
Kurt Hummel 
Kurt Hummel (Chris Colfer) is a singer who is bullied by the football team. He has a high vocal range, and is identified by Fox as a soprano singer. His voice could actually be described as a countertenor. Colfer originally auditioned for the role of Artie, however Murphy was so impressed by his performance that the role of Kurt was created for him, replacing a character named Rajish who was initially intended to be a member of the glee club. The character's name is derived from The Sound of Music's Kurt von Trapp, whom Colfer once played in a production of the musical, and the German Hummel figurines due to his complexion. Colfer describes Kurt as "a tough guy in designer clothes", explaining that he "puts on a very confident, 'I'm better than you' persona, but underneath it all he's the same anxious and scared teen everyone is/was at some point." Over the course of the first season, Kurt comes out as gay and develops a crush on Finn. He also joins the football team as a kicker, with Finn's help, and the cheerleading squad as a singer, though he ultimately quits both. In the episode "Wheels", he competes with Rachel to perform "Defying Gravity" from Wicked. Murphy selected the song after Colfer relayed a story from his own high school days, whereby his drama teacher refused to let him sing it because of his gender. Kurt becomes Finn's step brother in FURT
After Dave Karofsky bullies him into a depression early in the second season, Kurt becomes close friends with an openly gay student at Dalton Academy, named Blaine Anderson. After Karofsky kisses Kurt in the heat of an argument, Karofsky threatens him, saying that if Kurt were to tell anyone of the kiss that they shared, he will kill him. Kurt transfers to Dalton Academy to escape further harassment as a result. Kurt then joins Dalton's show choir, The Warblers, and falls in love with Blaine. The two then begin a relationship. Kurt eventually returns to McKinley, and they formally declare their love at the end of the second season, and at the beginning of the third season, Blaine transfers to McKinley to be with Kurt. The two have their first sexual experience in the episode "The First Time", and are still a couple at the end of the school year, though Blaine still has another year of high school after Kurt graduates. Kurt and Rachel both apply to the same New York drama school. Kurt becomes a finalist, and impresses the school's dean at his audition; he discovers the day of his graduation, however, that he was not accepted, though Rachel was. In first episode of the fourth season, "The New Rachel," Kurt and Rachel get an apartment together in New York. Kurt gets an internship at Vogue.com and inadvertently pulls away from Blaine; distraught, Blaine cheats on Kurt. After confessing to Kurt of his infidelity, Kurt severs all ties. Kurt begins to mend their relationship in "Thanksgiving" and they spend Christmas together in New York City.
Mercedes Jones 
Mercedes Jones (Amber Riley) is a "diva-in-training who refuses to sing back-up" with a "flair for fashion". Early in season one, Mercedes develops a crush on Kurt, unaware that he is gay. She is hurt when he rejects her, but supportive when he confides his sexuality. After this, the two become especially close friends. Dismayed at never receiving solo songs, Mercedes and Kurt join the cheerleading squad, the Cheerios, as vocalists. She briefly dates Puck, but ultimately breaks up with him and quits the Cheerios, afraid of turning into someone she does not want to be. She becomes friends with Quinn when the pregnant ex-cheerleader gives her advice during her stint on the Cheerios, and when Quinn is unhappy having to stay at Puck's house, invites Quinn to move in with her family. When Quinn gives birth, she asks that Mercedes be present for the delivery of her child. After junior prom, Mercedes and Sam begin dating secretly, but he moves away during the summer. Mercedes has a new boyfriend, Shane, by the beginning of the third season. In the third episode, Mercedes quits the glee club and joins the new, rival McKinley show choir, the Troubletones, run by Shelby Corcoran, later recruiting Santana and Brittany to join her. When the Troubletones lose Sectionals to New Directions and Shelby quits, they return to New Directions. Sam returns to McKinley and attempts to rekindle his romance with Mercedes. She still has feelings for him, and eventually breaks up with Shane, though she refuses to date Sam while she is unsure of her true feelings. Sam continues to support her, and a YouTube video he posts of Mercedes singing results in her being offered a job as a backup singer in Los Angeles after she graduates. In the fourth season, Mercedes has moved there and is taking classes at UCLA as well as being a backup singer, though she returns to help with the school musical, for Thanksgiving, and for Mr. Schuester's wedding. Eventually she gives up on doing an album after her producer pressures her into showing more skin on her CD cover art.
Santana Lopez 
Santana Lopez (Naya Rivera) is a cheerleader who joins the glee club in the episode "Showmance". Initially a spy for cheerleading coach Sue Sylvester, she comes to enjoy her club participation. Her romantic relationships with fellow members Puck and Sam are followed by the realization that she is in love with her best friend Brittany. Afraid of coming out as a lesbian, Santana uses football jock Dave Karofsky—who is also closeted—as a beard to bolster her heterosexual façade and to boost her chances of becoming prom queen, though she fails at the latter.
Having originated as a minor antagonist, Santana's role became more prominent in the second half of the first season, and she became a main character in season two. Rivera characterized Santana as "a bit of a bad girl", prone to sarcastic remarks. Though she stated in May 2009 that Santana "loves boys", she later deemed Brittany her character's soul mate. In March 2011, Falchuk confirmed, "Santana is a lesbian. She might not be ready to come out yet, but she is."
During the season three premiere, as a show of loyalty to Sue, she participates in setting one of the glee club's pianos on fire and is dismissed from New Directions by Mr. Schuester. She returns briefly to the club, and then abandons it for the new, rival McKinley show choir, the Troubletones, run by Shelby Corcoran, but when the Troubletones lose to New Directions at Sectionals and disband, she returns again. She starts dating Brittany. This is initially kept a secret, but after being outed as a lesbian by Finn, the relationship becomes public knowledge. Due to this, Santana is disowned by her grandmother. The New Directions, however, support Santana during her coming-out period. At Brittany's suggestion, Sue arranges for Santana to get a cheerleading scholarship to a top college program, though at graduation, Santana decides she wants to go to New York to perform, and her mother presents her with the money to help fund the attempt. Despite this, she ends up going to college in Louisville, Kentucky anyway, later breaking up with Brittany due to the distance. In the episode "Diva", it is revealed that Santana has dropped out of college and, upon Brittany's suggestion, moves in to Kurt and Rachel's apartment in New York.
Brittany Pierce 
Brittany Susan Pierce (Heather Morris) is a cheerleader who joins the glee club with Quinn and Santana in the episode "Showmance". Prior to appearing in Glee, Morris was a back-up dancer for Beyoncé Knowles. She was originally hired as a choreographer to teach cast members Colfer and Ushkowitz the "Single Ladies" dance. A week later, she was cast as Brittany. Morris had a recurring role throughout the first season, and was promoted to a series regular for season two. Many of Brittany's lines are unscripted, and are instead devised by Murphy during filming, or improvised by Morris. Morris portrays Brittany as being "literally insane". She is used by the series' writers to say things no other character would, to the point that Morris considers some of her lines nonsensical. Brittany's character traits include finding recipes confusing, cheating off intellectually disabled classmates and not knowing her right hand from her left. She makes her singing debut in the season two episode "Britney/Brittany", performing three songs—"I'm a Slave 4 U", "Me Against the Music" and "Toxic"—all by Britney Spears. Brittany has a physical relationship with Santana, in which Santana gives Brittany a hickey in the season 2 episode "Duets"; in that episode Brittany also has a brief romance with Artie that leads to a more serious relationship later in the season. She quits the cheerleading squad in "The Sue Sylvester Shuffle". In the episode "New York", Brittany tells Santana that she loves her far more than she's ever loved anyone else. In the third season, she is elected senior class president, defeating Kurt. She and Santana formally begin dating, and after Santana is outed by Finn, they are open about their relationship. Their relationship ends, however, when Santana breaks up with her due to the distance. She later develops a relationship with Sam. Jarrett Wieselman of the New York Post has compared Morris as Brittany to Lynch as Sue, deeming her "one of the funniest second bananas on TV".
Emma Pillsbury 
Emma Pillsbury (Jayma Mays) is the school's guidance counselor who has OCD, with obsessions and compulsions primarily focused on contamination and cleanliness. She has romantic feelings for Will. Mays has deemed Emma an "amazing" character to play, explaining: "I don't find that female characters are always written with a lot of depth, but she's so well defined on the page. Sure, she's terrified of germs and in love with a married man, so seeing her as the voice of reason for the kids is amazing." Glee's costume designer Lou Eyrich selects "quirky" outfits for Emma, to reflect her "sunny disposition". In an attempt to get over Will, Emma begins dating football coach Ken Tanaka, becoming engaged to him in the episode "Vitamin D". However, when Will is unable to attend a competition with the glee club, Emma volunteers to take them in his place, postponing her own wedding by several hours. Acknowledging her continuing feelings for Will, Ken breaks up with her on their wedding day. Emma submits her resignation as guidance counselor, but as she is leaving the school, Will finds her and stops her with a kiss. She reveals to Will that she is a virgin, but does not go through with her plan to lose her virginity to him. At the end of the first season, she tells Will she has started dating a dentist named Carl Howell, and in the second season her relationship with Carl (John Stamos) blossoms to the point that they get married in Las Vegas in the episode "Special Education". It is subsequently revealed in the episode "Sexy" that her marriage with Carl is facing difficulties and has not been consummated. She admits that she still has feelings for Will, and she and Carl separate; he later requests an annulment of their marriage. She begins to get treatment for her OCD in "Born This Way". When the third season begins, she and Will are living together. In the mid-season episode "Yes/No", Will asks Emma to marry him, and she accepts. In the penultimate episode, "Nationals", Emma and Will have sex for the first time.
Noah Puckerman 
Noah "Puck" Puckerman (Mark Salling) is Finn's best friend and football teammate, who initially disapproves of Finn joining the glee club. Puck joins Will's all-male a cappella group, the Acafellas, hoping to impress the mothers at the school's PTA meeting, as he prefers older women. He later discovers that he is the father of Quinn's baby. She rejects him when he offers to support her and the baby, calling him a "Lima loser." Later in the same episode, Puck joins the glee club. He briefly dates Rachel and Mercedes, but ruins his chances with Quinn by sexting Santana in her presence. Regardless, Puck attends the birth of his daughter, who he names Beth, and tells Quinn that he loves her. In season two, Puck is sent to juvenile detention for stealing an ATM. The producers engineered his absence from the series to allow a romance to develop between Quinn and new student Sam Evans. Following his return, Puck helps Artie hook up with Brittany, and recruits Lauren Zizes for glee club. He falls in love with Lauren, and they run unsuccessfully for junior prom king and queen together, but she breaks up with him at the beginning of their senior year in season three. Shelby Corcoran, who adopted baby Beth, gets a teaching job at McKinley, and invites Puck and Quinn to be a part of Beth's life, provided they both become more responsible. Puck does so, and Shelby allows him to see Beth. Quinn decides she wants to regain custody of Beth from Shelby, but Puck is torn, and tells Shelby of Quinn's plans. He then falls in love with Shelby. She sleeps with him once, though she tells him afterward she has made a mistake, to his disgust, and subsequently resigns from McKinley. Puck later gets into academic trouble, but realizes he needs to graduate after meeting up again with his high-school-dropout father, but he fails a crucial test that will keep him from graduating with the rest of the seniors. Coach Beiste breaks up a fight between him and another student, and helps him get a retest and to study for it. A kiss from Quinn brings back Puck's confidence: he passes the retest and graduates.
Terri Schuester 
Terri Schuester (Jessalyn Gilsig) was Will's wife of 5 years, but they were together 15 years total. Terri briefly believes herself to be pregnant, and pushes Will to take a better paying job as an accountant. She discovers she has actually experienced a hysterical pregnancy, but hides this from Will, afraid he will leave her. After confiding her deception in her sister Kendra, Terri approaches pregnant cheerleader Quinn Fabray, with an interest in her baby. She briefly becomes the school nurse, but is asked to step down after giving the glee club pseudoephedrine tablets. In the episode "Mattress," Will uncovers Terri's ruse when he discovers her pregnancy pad in a drawer. Terri begins attending therapy, but Will tells her he no longer loves her and leaves her as he falls in love with guidance counselor Emma Pillsbury. Their divorce is finalized late in the first season. Terri manages to seduce a sick and lonely Will in the second-season episode "The Substitute", but is re-buffed by her ex-husband as he expresses his need to move on. Near the end of the second season, Terri is recruited by Sue Sylvester to join Sue's League of Doom to destroy the New Directions glee club directed by Will, but Terri undoes the damage and tells Will that she's been promoted to manager at work, and is being transferred to a new store in Miami, Florida.
Gilsig has deemed Terri "a woman of conviction", willing to do "whatever it takes" to keep Will from leaving her. She explained that Will and Terri's communication is weak and that Terri is "missing a lot of the skills for the marriage," commenting that Terri feels threatened by Will's commitment to the glee club, worried that it will pull him away from her. Gilsig characterized Terri as emotionally still being in high school, and as of December 2009 did not know how long her character would feature in the series, as she was initially only created as an obstacle to come between Emma and Will.
Will Schuester 
William "Will" Schuester (Matthew Morrison) is McKinley High's Spanish teacher who becomes director of the glee club, which he renames New Directions, hoping to restore it to its former glory. Morrison has assessed that the crux of Glee is "about [Will's] passion for music and influencing his kids". Will is married to his high school sweetheart Terri. Believing her to be pregnant, unaware that she is actually experiencing a hysterical pregnancy, he considers leaving the teaching field to become an accountant. He ultimately decides against it, though briefly works after hours at the school as a janitor to earn extra money. His dedication to the glee club wavers when his choreography skills are called into question, but after starting a well-received all-male a cappella group, the Acafellas, he recommits to the club. After discovering Terri was faking her pregnancy, Will ends his marriage and shares a kiss with Emma. Their relationship does not solidify over the remainder of the season, however, and Emma starts dating Carl Howell (John Stamos) at the end of the school year. In the second season, though Will tries to win Emma back, she marries Carl. Will has a brief relationship with Holly Holliday (Gwyneth Paltrow) starting in the episode "Sexy". Holly takes a job in Cleveland, leaving Will free to pursue Emma after Emma's marriage ends in an annulment. April Rhodes returns and asks for Will's help with her new Broadway project: a one-woman show entitled CrossRhodes, but he ultimately decides that his students in New Directions are more important than his dreams of Broadway. At the start of the third season, Will and Emma are living together. He proposes to her after New Years and she accepts. He later switches from teaching Spanish to teaching history, though he continues directing the glee club. New Directions wins Nationals, he and Emma have sex for the first time, and eight of his seniors graduate at the end of the year.
Sue Sylvester 
Susan "Sue" Sylvester (Jane Lynch) is the coach of the cheerleading squad called the Cheerios, and the glee club's "arch-nemesis." Lynch states that Sue is "pure evil and doesn't hide it," having been created as a product of Murphy, Brennan and Falchuk's "inner mean girl." With regards to her motivation, Lynch explained: "Sue will do whatever it takes to win. If that means she has to prostitute herself or take advantage of a 16-year-old boy, she'll do it. It's all about power and winning. That's her entire world view." Sue enlists cheerleaders Quinn, Brittany and Santana to help her bring the glee club down from the inside. She has her own spot on the local news, which she uses to editorialize on issues such as support for caning and littering. At the end of the episode "Vitamin D", Sue is made co-director of the glee club, but soon scales back her involvement to an advisory role. In the episode "Wheels", Sue allows Becky Jackson (Lauren Potter), a girl with Down Syndrome, to join the Cheerios as a replacement for Quinn. It is later revealed that Sue has an older sister, Jean, who herself has Down Syndrome, showing a softer side to her normally abrasive character. Hoping to sabotage the glee club's chances of winning at sectionals, Sue gives the club's set list to rival glee club directors Grace Hitchens (Eve) and Dalton Rumba (Michael Hitchcock). When her actions are discovered by Principal Figgins (Iqbal Theba), Sue is suspended from the school. She is later reinstated after blackmailing Figgins, and wins her sixth consecutive national cheerleading title. In the season one finale, Sue judges in favor of New Directions at regionals, though they come third to rival clubs Vocal Adrenaline and Aural Intensity, and are disbanded for failing to place. Sue then blackmails Principal Figgins to reinstate the club, giving them another year to prove their worth to the school.
In the second season, Sue is appointed acting principal after having Figgins infected with the flu but she later stands down. Sue arranges to have the cheerleading regionals competition moved to conflict with the football championship, and she forces Quinn, Brittany and Santana to quit glee club, which has to perform the halftime show since the Cheerios will be absent; the three of them ultimately perform with the glee club, resigning from the Cheerios. Missing three of its best cheerleaders, the Cheerios lose regionals after six straight nationals wins. Faking a depression after the loss, Sue joins the glee club for a week; when she can't destroy it from within, she decides to coach one of their rivals, Aural Intensity, to a regionals victory over New Directions, but New Directions emerges victorious. Sue's sister, Jean, dies later in the season, and Sue is devastated and unable to cope; when New Directions helps with funeral arrangements and performs at Jean's funeral, Sue says she's giving up her frequent attempts to destroy the glee club, but she's back to her old ways in the third season when school starts in the fall. She also begins a run for a vacant Congressional seat, which she loses to Burt Hummel. In the episode "On My Way", Sue tells Quinn and Will that she's pregnant. She later finds out that she'll be having a baby girl, but it has birth defects. Figgins appoints swim coach Roz Washington (NeNe Leakes) Sue's co-coach for the Cheerios, but Sue makes a deal with him that if she helps New Directions win Nationals, she'll resume sole control of the Cheerios. Sue helps coach the glee club, and they win at Nationals, which puts her back in charge of cheerleading. In the fourth season episode 'shooting star' Becky fires two gun shots and Sue covers for her, and she is fired.
Supporting characters 
McKinley High students 
Wade "Unique" Adams 
Wade "Unique" Adams (Alex Newell) first appears in the third season episode "Saturday Night Glee-ver" as a new featured singer in Vocal Adrenaline who is a fan of both Mercedes and Kurt despite being a competition rival. Unique is a young trans woman, who wants to perform in competition. When she appears on stage in the Glee Club Regionals competition, Unique is a success—so much so that Vocal Adrenaline director Jesse St. James decides to build the group's Nationals routine around Unique, and to promote her as a show choir star. Unique is dismayed by the publicity and pressure, but after a pep talk from Kurt and Mercedes, performs in and wins the MVP award at Nationals competition, though Vocal Adrenaline comes in second to New Directions. Newell was a runner-up in The Glee Project's first season, and his prize was a two-episode arc on Glee. A possibility for his eventual character was described during a Project episode as "the lovechild of Kurt and Mercedes". In addition to his second full appearance in "Nationals", he also appears briefly in the episode "Props". In the fourth season premiere, Unique transfers to McKinley High and joins New Directions. She begins presenting as a girl in that episode during school hours, despite the pressure she experiences from classmates to appear in male attire. Though no staff or students at McKinley recognize Unique for the woman she is, some do accept that she "pretends" to be a woman, making her new high school slightly safer for her. In the fifth episode, "The Role You Were Born to Play", she tries out for and is cast in the female role of Rizzo for the school musical, Grease, but Sue Sylvester informs her parents in the following episode, "Glease", and they pull her from the show.
Azimio (James Earl, initially credited as "James Earl, III") is a McKinley High football player who was first introduced in the episode "Mash-Up", giving Finn Hudson grief over being in the glee club. Azimio is one of the school's bullies, and friends with teammate and fellow bully Dave Karofsky. Although he is usually seen harassing members of the glee club, Azimio was the first of the football players in "The Sue Sylvester Shuffle" to agree to perform in the halftime show the night of the championship game in order to be allowed to play in the second half, saying he wanted to win the game because it would mean so much to his father. Although he has typically been seen in tandem with Karofsky, he was featured on his own late in the second season, first as part of a "heckling club" organized by Sue to disrupt the glee club's benefit concert in "A Night of Neglect", during which he states that he writes devastating anonymous commentary in NCIS and CSI: Miami chat rooms, and then as one of Sue's staffers for the school newspaper when she revives The Muckraker in "Rumours" to spread damaging rumors about New Directions members. Karofsky, having given up bullying, confronts Azimio in "Born This Way" about his own bullying. Azimio appears once in the third season in "Asian F": he is still a member of the football team.
Jacob Ben Israel 
Jacob Ben Israel (Josh Sussman) is the editor of the school newspaper, in addition to running his own gossip blog. He has been compared in the media to Perez Hilton and Gossip Girl. Jacob has a crush on Rachel, who feels uneasy around him but relies on him for positive reviews. Although he attends Celibacy Club meetings, Jacob behaves in a sexually forward manner toward Rachel, threatening to sabotage her musical career unless she shows him her bra, blackmailing her for a pair of her panties in the episode "Throwdown" and masturbating over video footage of her in "Britney/Brittany." He briefly joins New Directions in order to fill the membership quota for sectionals, as a temporary replacement for Finn. Although he does not sing in the competition, he remains with the club throughout the remainder of the episode, helping them to listen in on the judges.
Seasons 2, 3 and 4 of Glee open with a documentary made by Jacob (referring to himself as "JBI"), focusing on the recent happenings at McKinley, and the glee club in particular. In addition to helping viewers catch up with the plot, the season two première episode "Audition" opens with one such documentary, which was used by the Glee producers to directly address media criticism of the first season.
Rory Flanagan 
Rory Flanagan (Damian McGinty) is an Irish foreign exchange student who is living with Brittany's family. Rory first appeared in the episode of the third season in "Pot o' Gold". Brittany was initially convinced that Rory was a magical leprechaun whom only she could see and was there to grant her three wishes. Additionally, Rory is a fan of Finn Hudson, and is persuaded by Finn to join New Directions—he auditions with the song "Take Care of Yourself" in a performance characterized by Rachel as "magical". Rory looks up to Finn, and tries to defend Finn when Santana insults him, only to get his own share of insults from her. He is given his first lead vocal in a Hall & Oates mash-up, singing one verse in a duet with Tina. The character of Rory was created for McGinty after he won a recurring role for seven episodes on Glee as a contestant on The Glee Project. The idea of his character interacting with Brittany was first broached in the penultimate episode of The Glee Project, with the judges speculating that Brittany would not be able to understand a word the character said due to his Irish accent. McGinty was retained as a recurring cast member past his initial seven episode prize through the end of the third season, but is not at McKinley as the fourth season begins.
Joe Hart 
Joe Hart (Samuel Larsen) first appears as a new transfer student to McKinley High in the third season episode "Heart". He is a Christian and has been home schooled until that point; he joins the "God Squad" club whose other members are three members of the glee club: Mercedes, Sam, and Quinn. After Quinn is in an automobile accident and confined to a wheelchair, he prays for her, and also helps her with her physical therapy; she, in return, recruits him into the glee club. Joe finds himself having feelings for Quinn and turns to Sam for advice, since the feelings are partially physical, which is frowned on by his faith. He continues at McKinley and in New Directions in the show's fourth season.
Larsen was one of the two winners of The Glee Project's first season, and his prize was a seven-episode arc on Glee. Like his character, Larsen is Christian, and had thought "being Christian and trying to make it in this business as opposites working against each other" and that "you have to be very secure in your faith to approach this business". He was therefore surprised—and thrilled—when his religious beliefs seemed to interest and inspire Glee's Ryan Murphy during an episode of The Glee Project.
Becky Jackson 
|This article is outdated. (May 2013)|
Becky Faye Jackson (Lauren Potter, narration provided by an uncredited Helen Mirren) is a member of the Cheerios with Down Syndrome, who becomes a sidekick to Sue. Potter is a member of the Down's Syndrome Association of Los Angeles, and was contacted about auditioning through the association's in-house talent agency, Hearts and Hands. Fourteen actresses auditioned for the role, which Potter deemed "a great experience" to perform. Becky appears in three episodes of the first season, "Wheels", "The Power of Madonna" and "Home" and returns in the second season as cheerleading coach Sue Sylvester's assistant. Becky does everything Sue tells her to do, including heckling the glee club in "A Night of Neglect", though her honest reactions to events have an effect on Sue. Becky is briefly kicked off the cheerleading squad by Sue in "Funeral" after Sue's sister, who also has Down Syndrome, dies; Becky asks to join the glee club, but she is told that it's too late in the show choir season, though she is offered a spot next year. Sue then apologizes to Becky, reinstates her, and tells Becky she'll be captain of the Cheerios in the fall. To Becky's dismay, when the third season commences she is not the sole captain, but is made co-captain with Santana. She also assists Sue with her Congressional campaign, though Sue loses the race. In the episode "Yes/No", she decides she wants Artie to be her boyfriend. She asks him out on a date, and while they do have a good time, he balks at a more serious relationship, to her great disappointment. Sue comforts her afterward. When Becky fails to get enough nominations to be on the ballot for senior class prom queen, she is very upset, and joins the anti-prom set up by Rachel and Kurt. She wins a game of strip poker with Puck after the others go to the prom after all, and he crowns the two of them the anti-prom king and queen. They then go to the real prom, and she helps him spike Sue's punch bowl. Becky is still a student at McKinley in the fourth season, still a Cheerio, and still Sue's aide-de-camp. In "Feud", Sue names her Cheerios co-captain again, along with the newly recruited Blaine Anderson.
Dave Karofsky 
Dave Karofsky (Max Adler) is introduced as a bully and McKinley High athlete in the episode "Mash-Up". He is a member of the hockey team who slushies Finn, but by "Theatricality" he's on the football team with his friend and fellow bully Azimio (James Earl); they regularly target members of New Directions. In the episode "Never Been Kissed", written to tackle the issue of LGBT youth bullying, Karofsky kisses Kurt during an argument. He later warns Kurt not to tell anyone about it, threatening to kill him if he does. He is expelled for his death threat, but allowed to return by the school board as no physical violence was witnessed—and Kurt had not revealed the kiss. He is briefly kicked off the football team with the other non-glee club members in "The Sue Sylvester Shuffle", but they return to perform the championship game's half-time show mashup of "Thriller/Heads Will Roll" with the club, and ultimately win the game. In the episode "Born This Way", after being blackmailed by Santana, he issues an apology to Kurt at a group meeting involving their fathers, Principal Figgins and Will. In "Prom Queen", when Karofsky wins prom king and Kurt, shockingly, wins prom queen, the two walk onto the floor for the traditional king and queen dance, but Karofsky is unable to come out as Kurt suggests, and leaves. He next appears in the third season episode "The First Time". He has transferred to another high school from McKinley for his senior year; he sees Kurt in a gay bar, and tells Kurt he has become a regular there and feels accepted. He is later outed at his new school and bullied so mercilessly that he attempts to commit suicide but is saved by his father; Kurt visits him in the hospital and they agree to become friends.
Adler had previously questioned his character's motivations, but was surprised by the scene in which Karofsky kisses Kurt. He commented that he was "glad to represent such a large group of people," expanding: "I've gotten so many messages from people all around the world these last couple of days thanking me because either they are Karofsky, they were Karofsky or they know a Karofsky." During the second season, show co-creator Ryan Murphy noted that "Glee is by nature optimistic and I think a character like Karofsky could turn to booze or pills or alcohol and kill themselves or do something dark. But I also love Max and I love that character and I sorta want that character to have a happy ending."
Ryder Lynn 
Blake Jenner, the winner of The Glee Project's second season, appeared starting with the fifth episode of season four as Ryder Lynn, a McKinley student who joins New Directions with Finn's aid. Ryder plays football, and is cast as the male lead in the school's production of Grease prior to his inclusion in the glee club. Ryder finds Marley trying to induce vomit in a bathroom. He tells her that she is beautiful and that it is not healthy to induce vomit, and kisses her backstage as Jake looks on. Jake Puckerman (Jacob Artist) and Ryder, who have been competing for Marley Rose's (Melissa Benoist) affections, are assigned to share their deepest fears with one another by Finn. Jake eventually admits that he feels insecure over being mixed-race and Jewish, while Ryder admits that he cannot read properly. Jake tells Finn about this, and Finn convinces Ryder to be tested, revealing that Ryder is dyslexic. He is directed to a professional and begins treatment to improve his studying. When Jake and Marley begin dating, Ryder struggles with his feelings for Marley. However, valuing his friendship with Jake and Marley's happiness, Ryder decides to suppress his feelings for her. In the episode Feud, Ryder has an online love interest named Katie. In the episode Lights Out, Ryder admits to the Glee club that he was molested as a child by his babysitter and it is looked on as "awesome" by Artie (Kevin McHale) and Sam (Chord Overstreet). Later in the episode, he finds out that Kitty (Becca Tobin) went through the same thing, they bond closer and Kitty begins to like Ryder.
Sugar Motta 
Sugar Motta (Vanessa Lengies) is a student at McKinley. Her father is the wealthy owner of a piano business who donates three repossessed pianos to the glee club in "The Purple Piano Project", the episode in which she first appears. Sugar has self-diagnosed Asperger syndrome, which she uses to explain why she can say whatever she wants. After the glee club performs in the school cafeteria in the hopes of recruiting new students, Sugar shows up to audition, telling the club that they're terrible but she's awesome and will be their new star. Her audition is a stunningly horrendous rendition of "Big Spender", and she becomes the first person who fails to get into New Directions after auditioning. In "I Am Unicorn", her father makes a huge donation to the school to set up a second glee club that will feature Sugar as the star, and recruits Shelby Corcoran to direct it. When Mercedes, Santana and Brittany join, Sugar assumes they'll be her backup singers, but Santana openly tells her she's not a good singer, and she should stay out of their way, at which point Sugar admits that she "just wanted to be on the winning team for once". Sugar has subsequently been seen dancing and singing in several polished performances, indicating that she has greatly improved. After the Troubletones place second at Sectionals, Shelby resigns as director, and the Troubletones are told they are all welcome in New Directions, Sugar accompanies Mercedes, Santana and Brittany when they return, and sings "We Are Young" with the group. Her first in-tune solo was in "Summer Nights" in "Yes/No". In "Heart", she gives Will money to pay for costumes and makeup for Regionals, and throws a big Valentine's Day party. Artie and Rory compete to be her date at the party, and Rory is chosen after his claim that he is being deported at the end of the school year wins her sympathy.
According to Lengies, Sugar's self-diagnosed Aspergers is part of her character. She said that it was difficult to sing poorly on purpose, especially with piano accompaniment. Sugar's debut was praised by Salon's Matt Zoller Seitz, who said of the new addition to McKinley, "She's awful. She's also an entitled little snot... She's a great character, and I hope we haven't seen the last of her." Entertainment Weekly's Abby West praised Sugar, and with Sue otherwise occupied hoped to see more of Sugar as "a thorn in the Glee club's side." On the other hand, TV Guide "jeered" Sugar, calling her "an off-key addition to the cast". The A.V. Club's Todd VanDerWerff concurred, and said of "I Am Unicorn", "Sugar continues to be one of my least favorite new characters in ages". The Huffington Post named Sugar Motta one of the "Worst TV Characters" in 2012.
Jake Puckerman 
Jake Puckerman (Jacob Artist) is a new McKinley High student who first appears in the fourth season premiere, "The New Rachel". He is a younger half-brother of Puck, who he's never met. He auditions for New Directions, but when he's stopped midway through his song, Jake is infuriated and deliberately knocks over a music stand. He is not admitted to the glee club, but when director Will Schuester discovers that Jake is related to Puck, he personally invites Jake to join New Directions, telling Jake that he is talented, and he thinks joining will help him as it did Puck, but Jake declines. In the following episode, "Britney 2.0", Will arranges a surprise meeting between the half brothers, and Jake later decides to join the glee club. Though there are signs that he and new club member Marley Rose might be interested in one another, she is upset to learn he is dating Kitty (Becca Tobin), the head cheerleader. Jake dumps Kitty after discovering she treated Marley disrespectfully. Later, Ryder and Jake compete for Marley's affections. As a result, they are assigned to share their deepest fears with one another by Finn. Jake eventually admits that he feels insecure over being mixed-race and Jewish. Soon after we see the relationship that Jake has with Ms. Rose the lunch lady, who is Marley's mom. He is seen congradulating her on her weight loss saying she looks great. Ms.Rose then tells Jake that Marley talks about him all the time, but Jake sighs and just talks about how he missed out on Marley and should have went for her when he had the chance and before she started having feelings for Ryder as well. Then two football players cruelly insult Marley's mom while standing in the lunch line. Jake is about to fight them in Ms. Rose's honor until they get other football players to join in the fight, outnumbering him. While Jake is threatened by a group of football players at school, Ryder and the New Directions members and Becky say that if they (the football players) mess with Jake they are messing with all of them. They walk away in defeat and Ryder tells Jake that he had his back (by telling Finn that he couldn't read and that he might have Dyslexia) and now he has got his back. Jake smiles and leaves the cafeteria conflicted. He calls Puck and asks for some brotherly advice about how to get Marley and how to keep Ryder as a friend. Puck tells him to play it cool and flirt and that soon Marley will be begging for it. It's later seen in the episode that Ryder has to re-scheduele the date that they planned so he can meet the dyslexia specialist early in the morning. Kitty tells Marley it's sounds like he's making up excuses because he's not attracted to her and Marley is mad and abruptly asks Jake out on impulse and he accepts. After their outing Jake feels guilty and ends up telling Ryder about the date saying they played song poppies all night and didn't do much of anything of a sexual nature. He sees Ryder is depressed by this truth, and Jake offers to break it off in order that they stay friends, but also mentions that he wasn't just going to 'hump her and dump her' and that Marley was different and very special in a way to plead with him so he could keep seeing her. Ryder said it was okay as long as he didn't take the dance solo from him for sectionals. Jake says it's plenty okay and is visibly happy that he can still see Marley and keep him as a friend. Marley and Jake then talk and she is disappointed when Jake reveals he's letting Ryder have the dance solo, telling him that he is a much better dancer and that there chances of winning sectionals will be diminished severely if he didn't take the dance lead. Jake tells her he doesn't mind and that Ryder is being really cool about them (him and Marley). He then offers to walk her to lunch and but she declines saying she's practicing for regionals. When Jake then sees Ryder trying to practice dancing he offers to help. Much to Ryder's dismay, he sees that Jake is actually a really good dancer. Ryder even tells Jake he should be the lead dancer at sectionals. Jake says that he doesn't want the solo because he knows how cool Ryder's being about him and Marley and that he doesn't want to take everything from him and he offers to help Ryder with the dance solo. The day of the competition Jake tries to comfort Marley because he can see she is visibly disturbed by the thought of it being her fault that they loose sectionals. He holds her hands and tries to comfort her but Ryder then hears this and for Marley offers the dancing solo to Jake saying he's the better dancer and that no amount of help is going to make him as good as he is. Jake takes the solo after considering Marley. In the middle of the Sectionals number when Marley faints, Jake and Ryder carry her and and along with the other New Directions force her to eat. After they find out they lost sectionals, Jake and Ryder join the basketball team when Glee Club is disbanded. Jake is seen comforting Marley throughout this entire episode. Then Christmas comes along and Jake spends it with his brother getting tattoos, going to California, and relaxing pool-side when Puck tries to convince his brother that a huge mansion belongs to him but it's later revealed that he only cleans the pool there. Jake is visibly upset when he finds out Puck lied, but the convinces his brother to move back to Lima and reunite their mothers. Puck agrees and they are seen being very close brothers. Now, Sadie Hawkins is here and it's revealed that Marley wants to ask Jake but that he's been really distant ever since she fainted at sectionals. Marley however with the help of Brittany soon develops the courage to ask Jake. He says yes. Kitty offers Jake sex in exchange that he dump Marley and take her to the Sadie hawkins dance instead, but he refuses. Jake and Marley are seen dancing together and Marley says that she really likes him but she's afraid that if she trusts him with her heart he might break it the second she gives it to him. He says she can trust him and that she's safe with him and he ask how can he prove it to her. She says that he has to be with her and ONLY her and they have to take things slow and if he complied to those requests that she'd be willing to be with him but if not then she wouldn't. Later on during the dance Jake agrees to the conditions saying all he wants is her she kisses him on the cheek.
Marley Rose 
Marley Rose (Melissa Benoist) is a transfer student to McKinley High who first appears in "The New Rachel," the fourth season premiere episode. She comes from a low-income family, her mother, Millie Rose, works at the school's cafeteria and is obese. Marley is initially introduced as a shy, sweet, intelligent "wallflower" who was frequently bullied and an outcast at her previous schools. Once she joins the glee club she forms friendships with the other students in the club. Marley is the only one of the many students who auditioned at the beginning of the school year to be immediately accepted into New Directions. Her goal is to become a singer on the radio, rather than aiming for Broadway. She is attracted to Jake Puckerman, who is also new at McKinley, but although the attraction seems mutual, she is upset to discover he is dating Kitty, a cheerleader and popular girl. Jake eventually breaks up with Kitty because she mistreats Marley. Marley auditions for the school's production of the musical Grease along with Wade "Unique" Adams, with whom she has formed a friendship, and is cast in the lead role of Sandy. In the episode "Glease", Kitty, who had been the other candidate for Sandy, convinces Marley that she is genetically predisposed to be overweight by secretly taking in her costumes, and that she needs to induce vomit in order to maintain a desirable weight. Ryder, who plays the male lead Danny, finds Marley trying to vomit in the bathroom, and tries to convince her it's a bad idea; he ends up kissing her backstage as Jake looks on. Jake and Ryder briefly compete for Marley's affections, but she chooses Jake, and they subsequently begin dating. Her bulimia gets worse, and she passes out on stage during Sectionals competition during New Directions' first number: when the glee club leaves the stage to get her first aid, the Dalton Academy Warblers are declared the winners, but they are later disqualified and New Directions gets to go on.
She and Jake are an official couple by the episode "Naked". Ryder helps Jake with ideas for Valentine's Day gifts for Marley, and at Will and Emma's wedding on Valentine's Day, she and Jake think about going "all the way", but Marley decides she isn't ready. Ryder, whose gift ideas were so successful because he'd fallen in love with Marley himself, kisses her when she thanks him for helping Jake with the presents. She tells Jake, which temporarily strains their relationship, and nearly ends Jake's friendship with Ryder. Finn, who had held the glee club together after Marley's fainting had almost ended it, has to leave New Directions when Will and he are at loggerheads. Marley goes to thank him as he's packing up, and when he says he'll miss teaching them, tells him he's a good teacher, and should get a teaching degree. By this time, Kitty has stopped sabotaging Marley and trying to undermine her confidence; in "Shooting Star", while the glee club is locked up in the choir room after gunshots are heard, Kitty breaks down and admits that she altered Marley's Sandy costumes.
In the episode Sweet Dreams, Marley debuts one of her original songs she wrote to fellow Glee Clubbers Blaine, Unique, and Sam. After performing the song with her, Blaine is the first person to say how incredible she is, and that they have to sing the songs she wrote. When Mr. Schuester overhears the song, he enlists her to write one for the club to perform at Regionals. At the end of Sweet Dreams, the club performs another one of her originals, Outcast. In the episode "Wonder-ful" she gets vocal and dance coaching from glee club graduates Mike Chang, Mercedes Jones, and Kurt Hummel. Her original song "All or Nothing" is performed, winning New Directions Regionals the third time in a row.
Matt Rutherford 
Matt Rutherford (Dijon Talton) is a football player who joins New Directions in the fourth episode, "Preggers", and appears for the remainder of the first season of Glee. He does not return in the second season; Will says that he transferred to another school. Talton has called Matt a typical football player with a talent for singing and dancing, who always wanted to perform but felt forced to choose between performing and being "cool". Talton explained that Finn joining the glee club made it more acceptable for Matt to be honest with himself about what he wanted to do, and that he is becoming more comfortable being in the glee club, "what it stands for, how it makes him feel". He said the following about Matt's characterization:
|“||I wanted Matt to be fun and just enjoy the moment [...] I think nowadays too many kids are concerned with people's opinions and judgments, and how that's going to affect them. At the end of the day the only thing that matters is if you're happy and if your own judgment for yourself is a good one. If you can look in the mirror and say, "I'm Matt Rutherford, or I'm Dijon Talton, and I'm happy with it," that's all that's important. That's what I wanted to bring to Matt.||”|

Kitty Wilde 
Kitty Wilde (Becca Tobin) is introduced as a new McKinley High cheerleader in "The New Rachel". Kitty is very popular and is attracted to Jake Puckerman and begins a relationship with him in "Britney 2.0", which ends in "The Break Up". Kitty eventually decides to audition for the role of Sandy the school musical Grease. Marley wins the role, which angers Kitty, who eventually starts to criticize Marley's weight and drives her to bulimia. Kitty joins the New Directions in "Dynamic Duets" along with Ryder Lynn and she seems to be a little bit nicer to Marley, even about her weight, however, it is learned that Kitty is pretending to be nice to Marley. She soon begins dating Jake's older half-brother Puck. After later episodes, it is shown that Kitty has become more sympathetic to the other glee club members, admitting that she considers everyone in New Directions her friends, and that she wants to win another Nationals championship. It is later revealed that Kitty was sexually abused by her friend's brother at a sleepover when she was in sixth grade, but no one had believed her. As a result, she transferred schools after all of her friends stopped talking to her and made her feel isolated. This could possibly explain the source of Kitty's negative behavior. During the episode "Shooting Star," Kitty confesses to Marley that during Grease she tightened her costumes so that she would think she’s gaining weight and apologizes for her bad behavior. Both Marley and Unique embrace her, forgiving her for what she did.
Lauren Zizes 
Lauren Zizes (Ashley Fink) is the McKinley High AV club president and a state champion in Greco-Roman wrestling. During the first season, Kurt tells his father that Lauren's parents had to sue the school district to get Lauren a spot on the wrestling team. Lauren has an acerbic personality and is admired by Puck for being "a bigger bad-ass" than he is. She is overweight and has a love of candy, specifically Cadbury Creme Eggs. Lauren has occasionally been seen dressing in the Goth style and is a fan of the Twilight book series. She joins New Directions in the episode "Special Education", enabling the club to meet the member quota for sectionals. Early in her tenure, she claims that show choir is stupid, but on several subsequent occasions she is seen enjoying singing and performing in the background. She performs "I Know What Boys Like", her first solo, in "Comeback". She campaigns with Puck for prom king and queen, though they both lose, and the two are still a couple at the end of the second season. However, after the glee club finishes twelfth at Nationals, Lauren concludes that being in New Directions is hurting her credibility, so she quits the group and breaks up with Puck at the start of the new school year. She returns in Season Four in the Sadie Hawkins episode as part of a Tina's group and goes to the dance with Joe Hart.
Other McKinley High students 
In the pilot episode, Pilot, Ben Bledsoe appears as Hank Saunders, a member of the McKinley glee club before its transformation into New Directions, singing Where is Love? from Oliver!. Sandy Ryerson is said to have behaved sexually inappropriately towards him, leading to Sandy's dismissal and a restructuring of the glee club. Hank does not audition to re-join the club, unlike Rachel, who does.
In the season one episode "Ballad", Sarah Drew makes a guest appearance as Suzy Pepper, a senior with "an insane, absurd, psychotic crush on Mr. Schuester." Drew described Suzy as "kind of stalkerish and creepy", but ultimately redeemable. James Poniewozik of Time commented positively on Suzy's characterization, observing that while she appeared to be a "throwaway dorky-girl stereotype", she was "fleshed-out as a person", a feat he doubted the series would have been capable of earlier in the season.
In season three, LaMarcus Tinker portrays Shane Tinsley, a new love interest for Mercedes and a "massive linebacker for the McKinley Titans". Rock Anthony appears as Rick "The Stick" Nelson, a hockey player who slushies Finn and runs for senior class president against Kurt and Brittany.
The William McKinley Jazz Ensemble frequently accompanies New Directions in their on-screen musical numbers. The student ensemble was introduced in the pilot episode, with Artie Abrams a member of that group as well as the glee club. Regular members of the group include a drummer played by John Lock and a bassist played by Scott Henson, both introduced in the pilot; a guitarist played by Spencer Conley, first seen in "Throwdown"; and a keyboardist played by Mark Nilan Jr., who first appears in "The Power of Madonna". Other student instrumentalists accompanying New Directions include string and horn players, additional guitarists, keyboard players and percussionists, and a harpist. The only instrumentalist to receive a co-starring credit is bassist Scott Henson (as "Scott T. Henson, guitarist") for having a line of dialogue in "A Very Glee Christmas". John Lock is frequently shown waiting for Finn Hudson to relinquish the drums to him, and Spencer Conley was featured in amongst the glee club females in their performance of the "Start Me Up / Livin' on a Prayer" mash-up in "Never Been Kissed". None of these instrumentalists have been given character names, and Conley and Nilan have not appeared in any third season episodes. Lock and Henson temporarily abandoned their instruments to sing and dance with New Directions for Sectionals competition in the episode "Hold On to Sixteen".
McKinley High faculty 
Shannon Beiste 
In the second season of Glee, Shannon Beiste (Dot-Marie Jones) is introduced as the new football coach for the McKinley High Titans in the premiere episode, "Audition". She comes to William McKinley High with an enviable record of coaching successful football teams, and Principal Figgins (Iqbal Theba) boosts the football program budget for her by reducing the cheerleading and glee club budgets, which alarms coach Sue Sylvester (Jane Lynch) and director Will Schuester (Matthew Morrison), respectively, and drives them into a temporary alliance against her. Beiste is dismayed by their rudeness, but forgives Will when he apologizes and goes on to develop a friendship with him. She contemplates resigning as coach upon learning that several students have been fantasizing about her in order to curb their arousal while making out. Will has the students apologize and earn her forgiveness. When antagonism flares between the football team's glee and non-glee factions, Beiste forces the entire football team to work together with the glee club for one week; despite encountering resistance and set-backs, the plan is ultimately successful and the team wins the championship game. In the third season, Beiste continues as football coach, and is recruited by Will to co-direct the school musical West Side Story with guidance counselor Emma Pillsbury (Jayma Mays) and Artie. She orders her football team to play the Jets in the show. She also takes on the task of running the school elections. In the episode "The First Time" she begins dating Ohio State football recruiter Cooter Menkins (Eric Bruskotter), who is scouting for talent at McKinley, but discovers in "I Kissed a Girl" that Sue has become her rival for Cooter's affections just as she comes to realize that she loves him, thus prompting her first solo song, "Jolene". She later tells Emma and Sue, in episode "Yes/No", that she and Cooter have impulsively gotten married. A few months later, in the episode "Choke", she is hit by her husband, Cooter, and given a black eye. Although initially convinced by Sue and Roz Washington (NeNe Leakes) to leave for her own safety, Beiste later returns home and gives Cooter a second chance, though she does ultimately leave him and gives him back her wedding ring.
One article described Beiste as a "wounded giant—a 40-year-old who'd never been kissed", and Jones's portrayal of her as "humorous and heart-wrenching". Jones had previously worked with Glee co-creators Ryan Murphy and Brad Falchuk on Nip/Tuck, and when she encountered Falchuk at a local supermarket she says she told him, "'Write me something', just joking, you know, but not really." Still, she was shocked to hear from her agent two months later that Murphy had done so. She knew very little about the role initially: "When I signed my contract, it didn't even have a character name—just two quotation marks." In her acting career, Jones has "played every tough chick possible", and in early 2012 described the role of Beiste as one "where I still get to be the tough coach, but be vulnerable, have heart and have a love interest". Jones received an Emmy nomination for Outstanding Guest Actress in a Comedy Series for her work as Beiste in Glee's second season, and submitted her performance in the episode "Never Been Kissed" for final judging. She was one of three actresses from the show to be nominated in that category in 2011; the victor was another Glee nominee, Gwyneth Paltrow. She was also part of the Glee cast ensemble that was nominated in December 2011 for the Outstanding Performance by an Ensemble in a Comedy Series award at the 18th Screen Actors Guild Awards. In 2012, Jones was nominated for an Emmy again, the only actor from Glee nominated that year.
Shelby Corcoran 
Shelby Corcoran (Idina Menzel) is the coach of rival glee club Vocal Adrenaline during season one, described by Murphy as "a sort of Faye Dunaway of Network". She makes out with Will shortly after meeting him, but she resists sleeping with him when he says his divorce is not yet final and that he has just broken up with his new girlfriend, Emma. Fans had lobbied for Menzel to be cast as Rachel's biological mother, due to the strong resemblance between Menzel and Michele. In the episode "Dream On", it is revealed that Shelby is, in fact, Rachel's biological mother. She had signed a contract that stated that she could not seek out her daughter until she was eighteen. In the season one finale, "Journey to Regionals", Shelby adopts Quinn Fabray and Noah Puckerman's newborn daughter, Beth. She leaves Vocal Adrenaline before the beginning of the next school year.
Shelby returns in the second episode of season three, "I Am Unicorn", having been recruited to lead a second glee club at McKinley High by Sugar Motta's father when Sugar is refused entry into New Directions. Shelby offers to include both Quinn and Puck in Beth's life. In "Pot o' Gold", Shelby tells Puck that she is struggling at being a mother; as the episode ends, they kiss. Puck falls in love with her, but Shelby tells him in "Mash Off" that the kiss was a mistake. She compounds the mistake in "I Kissed a Girl" when she sleeps with him, and Shelby resigns from McKinley in the eighth episode, "Hold On to Sixteen".
Principal Figgins 
Principal Figgins (Iqbal Theba) is William McKinley High School's "stern but fair" principal. Figgins allows Will to take over the school glee club; however, he insists that the students must place at Regionals in order for the club to continue. He is blackmailed by Sue for most of the first season: she uncovers internet footage of him appearing in a support stocking commercial for Mumbai Air, and she later drugs his drink and takes a compromising photograph of them in bed together. In the second season, Sue serves as Figgins's temporary replacement when he catches the flu, and succeeds in having him fired, becoming principal in his stead. She resigns in the following episode, however, and he is reinstated. Near the end of the season, he hires the glee club to perform at the school's junior prom.
Although Figgins was initially conceived as White, Pakistani American actor Theba was cast in the role. He finds Figgins a challenging character to play, as it entails finding "the right mix of someone who is an authority figure but who is also very insecure about his own strengths as a person."
Holly Holliday 
Holly Holliday (Gwyneth Paltrow) is a substitute teacher at McKinley High. Her first appearance was in the second season episode "The Substitute", when she temporarily takes over as the director of the glee club while Will Schuester is out sick. Paltrow's Glee appearance marked her first ever scripted-series guest performance. The role of Holly was created for her by series creator Ryan Murphy, a personal friend who suggested that she showcase her vocal and dancing talent ahead of the December 2010 release of the film Country Strong, in which Paltrow plays a country singer. Holly makes a return appearance in the episode "Sexy", this time subbing for McKinley's sex education teacher. In that same episode she also begins a romantic relationship with Will. Holly's third and final appearance that season is in the episode "A Night of Neglect", in which she breaks off her relationship with Will because she knows he is in love with Emma. Murphy stated at PaleyFest in March 2011 that Paltrow as Holly would be returning in season three for a series of guest appearances, but she has not appeared on Glee in the two years since that announcement.
Sandy Ryerson 
Sandy Ryerson (Stephen Tobolowsky) is the former director of the McKinley High glee club. Although he claims to have a girlfriend, Rachel refers to him as a "closet case", and he is fired for his inappropriate sexual behavior towards a male student. Following his firing, he becomes a drug dealer, reselling medical marijuana. When he wants to join Will's band, the Acafellas, they initially reject him for being too "creepy", but change their minds when he tells them that Josh Groban is a friend of his and will attend their next performance if Sandy is in it. While Groban does attend, he does so only to serve Sandy with a restraining order for constantly sending him inappropriate photos and messages over the internet. Colluding with Sue Sylvester to bring down New Directions, Sandy is appointed the school's arts director. Sandy appears in Rachel's music video for "Run Joey Run", playing her father, and gives Will advice about beating rival glee club Vocal Adrenaline. His behavior is often eccentric, including doll collecting, writing fan fiction about Desperate Housewives, and attempting to create a role for himself as Cleopatra in the school production of Cabaret. The casting notice for the role of Sandy read, in part, "He's gay, but covers it ... most of the time. With a pastel sweater thrown over his shoulders, Sandy is the former Glee Club teacher, who is given the axe after an episode of inappropriate touching." Tobolowsky, who plays Sandy, describes him as a humorous character who "just cannot connect with the normal world" and exists on the "outer boundary of reality". Tim Stack for Entertainment Weekly has praised Sandy as "one of the most reliable characters for great lines and laughs". In the first few episodes, it was implied heavily that Sandy was gay. The second season episode "A Night of Neglect" confirmed this, with Sandy characterizing himself as a "predatory gay". In that episode, he joins Sue Sylvester’s "League of Doom", using the codename "The Pink Dagger", but ends up donating money to support the school's academic decathlon team, spoiling Sue's plans.
Ken Tanaka 
Ken Tanaka (Patrick Gallagher) was the head coach of the football team and was previously engaged to Emma. Gallagher has stated: "I think you understand where Ken comes from as they go on. You understand where the bitterness comes from, and people may start to like him a little. Ken will keep going [after Emma]. Ken will go after what he wants. The one thing Ken won't do is give up." Though Gallagher is Chinese-Irish, Ken is Japanese. Comparing himself to his character, Gallagher detailed: "I'm more like him than I care to admit. I realized I was going for what I like to think as an older version of me from years ago. I think Ken is not happy with where he is in life. I think he's still got a good heart, but there's this insecurity and bitterness piled on top of it. I think love is in Ken's head, and love for me is kind of an idealistic concept. But one thing I really respect about him is that he goes after something: He just doggedly pursues Emma. I wish I was more like that. In some ways, he's a little bit braver than I am. I mean—look at what he wears. That takes guts." Gallagher finds the character interesting, as to play the role he has to face his own "insecurities" and "bitterness". Gallagher feels that he draws much of Ken's characterization from himself, while also "channeling" his high school gym teachers. He commented: "the real challenge is to find the balance between not trying to be too funny, not trying to make it funny, just letting it be funny, and just delivering the line and letting the writing do the work for you."
Roz Washington 
Roz Washington (NeNe Leakes) was first introduced in the third season episode "Yes/No" as McKinley High's new synchronized swim coach, a sport in which she received an Olympic bronze medal. Coach Roz appeared again in "The Spanish Teacher", during which she directs a routine for the Cheerios, to cheerleading coach Sue Sylvester's disgust. Roz manages to convince Principal Figgins to appoint her as cheerleading co-coach, which outrages Sue who doesn't want to share power, though the two team up to teach the glee club girls that spousal abuse is nothing to joke about. Sue makes a deal with Figgins: if she helps the glee club win the Nationals competition, she will regain full control of the Cheerios. The club wins Nationals, and Sue is triumphant.
The role of Roz was created by Ryan Murphy, who noted that Leakes herself was part of the inspiration for the character, from her appearances on The Celebrity Apprentice and Bravo's The Real Housewives of Atlanta, and only afterward did he realize he could offer the role to Leakes herself. Ian Brennan writes most of Roz's dialogue, much as he write most of Sue's. Leakes as Roz has received mostly praise for her work. Billboard's Rae Votta said she was "arguably the best part" of "Yes/No", and after her second appearance in "The Spanish Teacher", declared that the show "should never let NeNe go". Crystal Bell of Huffington Post said of her first appearance only that Leakes "does well", but by the time of her third appearance in "Big Brother", after having praised guest star Matt Bomer, she added that "he's no NeNe Leakes, but not everyone can be that fabulous". One dissenting opinion came from BuddyTV's John Kubicek, who liked the writing for Roz, but wrote that Leakes was "an embarrassingly terrible actress".
Other McKinley High faculty 
John Lloyd Young guest stars in the episode "Acafellas" as Henri St. Pierre, "a retired wood shop teacher with an excellent singing voice". Molly Shannon appears twice during the first season as Brenda Castle, an alcoholic astronomy teacher and badminton coach who clashes with Sue. Brad Ellis has a recurring role as Brad Ellis, the pianist who accompanies New Directions, and did not show any sympathy towards the club when they lost Sectionals in 2012. Barbara Tarbuck appears in the third season as Nancy Bletheim, a geometry teacher who's been at McKinley High for 42 years, who supports Sue's congressional run. Mary Gillis plays Mrs. Hagberg, who appears in "Prom Queen" teaching home economics, in "I Am Unicorn" teaching geography, in "I Kissed a Girl" teaching math, and retires from her tenured position as a history teacher in "The Spanish Teacher", though she returns for an end-of-the-year ceremony in "Nationals". Ricky Martin portrays David Martinez, a night school Spanish teacher, in the episode "The Spanish Teacher". He replaces Will as McKinley's Spanish teacher; Will instead begins teaching history. Jean Sincere had a recurring role as the school's "Ancient Librarian" in 2010 and 2011.
Rival choir personnel 
Sunshine Corazon 
Sunshine Corazon (Charice Pempengco) is a foreign exchange student from the Philippines. Rachel invites her to join the glee club after seeing Sunshine sing along to New Directions' version of "Empire State of Mind", mistakenly thinking that Sunshine idolized her, but when the two sing "Telephone", Rachel feels threatened by Sunshine's singing prowess and tricks her into going to a crack house instead of the auditions. Rachel is found out, and Sunshine eventually does audition, amazing the club with "Listen". Though she is immediately accepted into the club, Sue Sylvester contacts Dustin Goolsby, the new director of rival glee club Vocal Adrenaline, who secures permanent U.S. residency and a condominium unit for Sunshine and her mother provided that she joins his club. Sunshine confesses that she would have loved to be in New Directions, but she felt that Rachel would have made her stay a "living hell". In "A Night of Neglect", Sunshine appears as a member of Carmel High's academic decathlon team that loses in the semi-finals to the McKinley High team. Sunshine hears of New Direction's fundraising benefit for the McKinley team's finals expenses and volunteers to perform, promising to get her Twitter followers to attend. They accept her offer after she sings "All By Myself", but Dustin Goolsby pulls her out of the fundraiser and her fans do not come. Sunshine reappears in the season two finale "New York" for the National show choir competition. Sunshine tells Rachel that she has come to hate being in Vocal Adrenaline, and desperately wants to leave on the day of competition. Rachel encourages her to perform and apologizes for what she did to her at the beginning of the year. Sunshine sings the original song "As Long As You're There", and the group places in the top ten; it is later revealed that they came in second.
Dustin Goolsby 
Dustin Goolsby (Cheyenne Jackson) is the director of rival glee club Vocal Adrenaline who replaces Shelby Corcoran (Idina Menzel) when she leaves the post after leading the team to four national championships in a row. Murphy described Dustin as "a complete villain", stating that he will "become very intertwined in Will's life". He is first introduced in the episode "Audition", escorting his new recruit Sunshine Corazon out of William McKinley High School and taking her away from its glee club, having been tipped off about her by Sue Sylvester, and employed the underhanded tactics of offering to sponsor Sunshine's visa and arranging an apartment for her and her family as payment for her joining Vocal Adrenaline despite her being enrolled at McKinley High. He returns in "A Night of Neglect", joining Sue's "League of Doom" to help her sabotage the McKinley glee club, and returns again at the National show choir competition in the season two finale, "New York", where Vocal Adrenaline comes in second—as is subsequently revealed in the third-season episode "I Am Unicorn"—and Goolsby is fired as director for failing to win a fifth national crown.
Jackson was originally considered for the role of Will, and in 2009 was initially cast in the Glee episode "Acafellas" as Vocal Adrenaline choreographer Dakota Stanley, but he was unable to perform due to illness.
Harmony (Lindsay Pearce) is introduced in "The Purple Piano Project" at an Ohio mixer for future applicants to the New York Academy of Dramatic Arts (NYADA), and is one of a group of aspiring students to have been attending monthly since they were freshmen. She has been working in show business since before birth—an ultrasound of her was featured in an episode of Murder, She Wrote, and she later appeared in commercials for Gerber baby food. When Rachel and Kurt come to their first NYADA mixer, Harmony sings lead on an extensively choreographed mashup of "Anything Goes" and "Anything You Can Do" from the musicals Anything Goes and Annie Get Your Gun, which intimidates the two new arrivals. She returned in "Hold On to Sixteen", leading her glee club, the Unitards, to a third place finish at Sectionals, after which she tells Kurt that she's a sophomore. Harmony is portrayed by The Glee Project runner-up Pearce, and her debut was met with critical acclaim. Todd VanDerWerff of The A.V. Club wrote that hers might be "the best new character ever", and TVLine's Michael Slezak felt that Harmony was "brilliantly bought to life" by Pearce. Kevin Fallon of The Atlantic said that her introduction bodes well for future Glee Project contestants and that "she brought, which the best new characters do, fresh and exciting aspects in the show's established leads". Lisa Respers France of CNN named Pearce's performance the best moment of the episode, and found that the character positively reminded her of "Glee of old". However, AfterEllen.com's Christie Keith was more critical of her appearance, and wrote, "Since Lindsay is one of the reasons I couldn't stand to watch The Glee Project, and no, she can't sing remotely as well as Lea Michele, and none of the boys there was close to being as darling as Kurt, I was forced to suspend disbelief when the whole experience devastated Kurt and Rachel."
Grace Hitchens 
Grace Hitchens (Eve) is the show choir director of the Jane Addams Academy for troubled female youth. She is persuaded by Sue to use songs from New Directions' set list at Sectionals to give her group an edge in the competition. Though she feels guilty after the fact and attempts to inform the judges of her cheating, they have already unanimously chosen New Directions as the winning club. She and rival glee club director Dalton Rumba give Principal Figgins proof that Sue helped them cheat, leading to Sue's suspension. When comparing her character to McKinley High glee club director, Will Schuester, Eve explained: "I come from a harder place. I'm the teacher of a reform school. I'm used to being very strict." Whitney Houston had been contacted to appear, but declined, so Eve took her place. Discussing her casting, Eve stated: "I got asked and I'd heard the buzz about the show. When the first pilot episode came out, I figured it was something different and something we haven't seen on TV before. I didn't want to turn it down!" Gerrick D. Kennedy for the Los Angeles Times was impressed by Eve's acting and "on-screen charm", and felt that she worked nicely in the "Hairography" episode. In contrast, Bobby Hankinson for the Houston Chronicle was disappointed Houston had not taken the role, and criticized Eve for her lack of personality.
Sebastian Smythe 
Sebastian Smythe (Grant Gustin) is a student at Dalton Academy who transfers into the school in the show's third season. He is introduced as a new Dalton Academy Warbler in the fifth episode, "The First Time". When Blaine Anderson, the former lead singer of The Warblers who has transferred to McKinley High, comes to Dalton to invite his Warbler friends to see a musical he's starring in at McKinley, Sebastian is attracted to him and propositions him, but Blaine is happy with his current boyfriend, Kurt Hummel, and turns him down. Sebastian suggests that he and Kurt join him at a local gay bar, though his further efforts to come between Blaine and Kurt are unsuccessful, and Kurt later warns Sebastian away. Sebastian becomes captain of the Warblers, and in "Michael", he spikes the New Directions plan to do Michael Jackson songs at Regionals by adding Jackson's music to the Warblers setlist, and when the McKinley glee club challenges the Warblers for the right to use Jackson, throws a slushie spiked with rock salt that injures Blaine—Kurt was the intended target—such that he needs surgery to repair his cornea. Santana gets him privately to admit his perfidy, but unknown to Sebastian his admission was taped, and the other Warblers are made aware of his actions. Undeterred, Sebastian tries to blackmail Rachel into not competing at Regionals by threatening to post faked nude pictures of Finn on the internet, but destroys the pictures after Dave Karofsky attempts suicide—Sebastian had cruelly rebuffed Karofsky at a gay bar, and blames himself. The Warblers lose to New Directions at Regionals. Sebastian returns in the fourth season, although he loses the position of Warbler captain to Hunter Clarington. He is a part of the effort to persuade Blaine to rejoin the Warblers.
When Gustin made his first appearance, it was reported he was playing a new "major" recurring character, a "gay Dalton Academy Warbler who sets his sights on Blaine". Gustin won the role after "an exhaustive, weeks-long casting search", and the character is referred to as "promiscuous" and "scheming". Gustin's first day on the Glee set was September 26, 2011. He had been playing the role of Baby John in the touring company of Broadway revival of West Side Story since it opened on September 30, 2010, and left the show after performing on September 23, 2011 to return for his first day with Glee.
Jesse St. James 
Jesse St. James (Jonathan Groff) is the male lead of Vocal Adrenaline and one of the main antagonists of the first season. He is directed to befriend Rachel by Vocal Adrenaline coach Shelby Corcoran, who is secretly her biological mother. Jesse and Rachel begin dating, and he briefly transfers to McKinley High, joining New Directions. Once the truth about Shelby is revealed, however, Jesse transfers back. He ends his relationship with Rachel by egging her in the McKinley High parking lot along with his fellow members of Vocal Adrenaline, humiliating her. In the episode "Prom Queen", he returns, after having flunked out of college, in an attempt to befriend Rachel again, claiming that his biggest regret was choosing Vocal Adrenaline over love. He joins Rachel, Sam and Mercedes, who have teamed up to go do "prom on a budget", at the McKinley junior prom; however, after getting into a fight with a jealous Finn, he's kicked out of prom. He sets up a consulting business to help show choirs with their performances; his first client is New Directions. His resumed relationship with Rachel ultimately fails when Finn suddenly kisses her in the middle of a Nationals performance and Rachel chooses to get back together with him. Jesse returns in the latter part of the third season as the new coach of Vocal Adrenaline, replacing the fired Dustin Goolsby. He and Rachel have a friendly moment when she encourages him on his first Nationals as Vocal Adrenaline's coach, and he tells her he likes her cocky side. He also (somewhat mockingly) congratulates Finn on being engaged to Rachel. Later, after sadly watching Rachel perform on Nationals (and implying he still has feelings for her), Jesse talks to Carmen Tibideaux (Whoopi Goldberg) and tells her Rachel's the most talented person he knows.
In a controversial essay for Newsweek, critic Ramin Setoodeh wrote that Groff, who is openly gay, was unconvincing as the straight Jesse ("he seems more like your average theater queen, a better romantic match for Kurt than Rachel"). Groff's performance was defended by Murphy and guest star Kristin Chenoweth, both of whom described Setoodeh's essay as homophobic; it was also condemned by GLAAD president Jarrett Barrios.
Other rival choir personnel 
Whit Hertford appears as Dakota Stanley, a glee club choreographer who worked for Vocal Adrenaline early in season one, and was briefly hired by New Directions. Michael Hitchcock appears as Dalton Rumba, the coach of the Haverbrook Deaf Choir. Senior Dalton Academy Warblers from the second season include Wes (Telly Leung), David (Titus Makin, Jr.), and Thad (Eddy Martin), who run the group's meetings. Another Warbler is Nick (Curt Mega), who sings lead for the Warblers in the third season. Jeff (Riker Lynch) and Trent (Dominic Barnes) are also fellow Warblers. Hunter Clarington is introduced in the fourth season's seventh episode as the new captain of the Warblers. Played by Nolan Gerard Funk, Hunter is a new Dalton transfer student, recruited from a Regionals-winning military academy.
Family of McKinley students and faculty 
Kendra Giardi 
Kendra Giardi (née Del Monico; Jennifer Aspen) is Terri Schuester's sister. She and her husband Phil (Michael Loeffelholz) have triplet sons (played by Ethan, Aidan, and Ben Freedman). She influences many of Terri's decisions during her hysterical-turned-fake pregnancy by assisting Terri in her schemes, and predicting disaster whenever Terri contemplates confessing the truth to Will. In the episode "Throwdown", Kendra and Terri bully their obstetrician, Dr. Wu (Kenneth Choi), into faking an ultrasound to convince Will the baby is real. Entertainment Weekly's Wendy Mitchell deemed Kendra "hilarious" and wished to see more of her, while her colleague at the magazine, Ken Tucker, described Kendra as "a garish cartoon who exists only to further the pregnancy plotting".
Carl Howell 
Carl Howell (John Stamos) is a dentist, introduced in "Britney/Brittany" as Emma's boyfriend. As a fan of The Rocky Horror Picture Show, Carl volunteers to play Eddie in McKinley High's school production of the musical. He dislikes Emma and Will spending time alone together, aware that Will has feelings for her. In the episode "Special Education", Carl and Emma marry in Las Vegas. However, after Emma naively advocates abstinence to the glee club with a performance of "Afternoon Delight", a song actually about the joys of sex, Carl requests a private couples counseling session with Holly Holliday, the acting sexual education teacher, as his and Emma's marriage hadn't been consummated after four months. Holly forces Emma to admit she is still attracted to Will, leading to Carl walking out and filing for annulment.
Carole Hudson 
Carole Hudson (Romy Rosemont) is Finn's widowed mother and Kurt's stepmother, and wife to Kurt's dad Burt. When Finn was young, she had a relationship with a lawn-care worker who left her for a younger woman. Upon discovering that Quinn is pregnant, she allows her to move in with them when Quinn's father kicks her out. Kurt sets Carole up with his father Burt in an attempt to get closer to Finn. They decide to move in together, until Finn uses a homophobic slur against Kurt and Burt refuses to allow him to stay in his home. Their relationship continues, however, and Carole visits Burt's bedside when he suffers a heart attack early in the second season. She marries him later that fall. James Poniewozik of Time felt that Carole's reaction to the news of Quinn's pregnancy demonstrated how far Glee had evolved from the "broadly caricatured show" it was in its early episodes. He commented that in the pilot episode, Carole was "just the slightly pathetic figure we saw pining after the lawn-care guy", however her reaction to Quinn's pregnancy was "a brilliant bit of characterization through small moments", an example of how Glee was "becoming very good at showing how life happens in small exchanges in people's laundry rooms and finished basements".
Millie Rose 
Millie Rose (Trisha Rae Stahl) is introduced in "The New Rachel" as the lunch lady and Marley Rose's mom. She is made fun of by students and the glee club members initially for her weight, but when they discover she is Marley's mom they stand up for her. She makes all of Marley's clothes and is particularly fond of Marley's boyfriend Jake Puckerman and the rest of New Directions. In the episode "Glee, Actually" Sue breaks into her house and stocks it with presents and money. Millie tries to give it back, but Sue refuses to take it, so she brings Sue to the auditorium where the New Directions perform "Have Yourself a Merry Little Christmas" for her.
Jean Sylvester 
Jean Sylvester (Robin Trocki) is Sue Sylvester's older sister. Jean, who has Down syndrome, lives in an assisted living facility, and is the only character Sue consistently treats with care and compassion. She is a factor in Sue's decision to admit Becky Jackson—who also has Down syndrome—to the Cheerios. Jean dies near the end of the second season, in the episode "Funeral".

Acquaintances of McKinley students and faculty 
Rod Remington 
Rod Remington (Bill A. Jones) is a television news anchor on the newscast where Sue Sylvester has an opinion segment ("Sue's Corner"). Rod and Sue had a brief relationship shortly after his wife drowned that began and ended in the episode "Mash-up"; she caught him making out with his co-anchor, Andrea Carmichael (Earlene Davis). Rod and Andrea later marry and announce it during a newscast in the episode "Furt", humiliating Sue. As a local celebrity, Rod has been tapped to judge show choir competitions—he has appeared as a judge for three of those that New Directions has competed in: the first season's Sectionals competition, and the Regionals competitions for the first two seasons.
April Rhodes 
April Rhodes (Kristin Chenoweth) is a former member of the glee club who never finished high school and ended up hitting rock bottom, as well as Will's high school crush, who never acknowledged his existence. She briefly rejoins the glee club as an adult, during a period of time in which Rachel had left the club and it was in need of a female lead. During her revisit to the school, she gives muscle magazines and alcohol to Kurt, she teaches Mercedes and Tina how to shoplift, and has a brief romance with Puck. April appears once again, at which point she has become the mistress to an elderly tycoon and is the owner/operator of a "cabaret roller rink". Suddenly her boyfriend dies and she is paid $2 million in hush money by the widow not to go to the newspapers. April then decides to buy the glee club their auditorium back, now called The April Rhodes Civic Pavilion, and return to Broadway to back an all-white version of The Wiz. The show flops, and she returns in the season 2 episode "Rumours" to get Will's help with her new one-woman show, CrossRhodes. Robert Bianco for USA Today wrote of Chenoweth's guest appearance in "The Rhodes Not Taken": "Her presence may not make much sense, but that's probably all right. If it means hearing Chenoweth sing, we can put up with any explanation the show cares to offer." Raymund Flandez for The Wall Street Journal was equally positive regarding Chenoweth's role, praising her "powerful voice", "kittenish mien" and "commanding presence". Eric Goldman for IGN stated that Chenoweth was "terrific" as April, and that the character was a "hysterical creation". The Los Angeles Times Denise Martin praised Chenoweth's versatility as April, opining that her performance was worthy of a second Emmy win.
Bryan Ryan 
Bryan Ryan (Neil Patrick Harris) is Will's high school nemesis. Bryan appears in "Dream On" as a school board member, out to cut district arts programs and the McKinley High glee club in particular as revenge for the latter giving him false hope back when he was its lead singer. Harris won the 2010 Primetime Emmy Award for "Outstanding Guest Actor in a Comedy Series" for his appearance.
Other acquaintances of McKinley students and faculty 
Guest stars have included Josh Groban and Olivia Newton-John, who appeared as themselves both separately and acting as judges at the first-season show choir regionals competition. The second season's regionals judges are played by Kathy Griffin and Loretta Devine as Tammy Jean Albertson and Sister Mary Constance, respectively. In the third season, the judges for the nationals competition are Lindsay Lohan and Perez Hilton appearing as themselves, and Rex Lee as Chicago Alderman Martin Fong. Kent Avenido appears in the first two seasons as Howard Bamboo, Terri's dyslexic coworker who joins the Acafellas and later Sue's "League of Doom", and Kenneth Choi plays Dr. Wu, Terri's obstetrician. Earlene Davis plays Andrea Carmichael, Rod Remington's TV news co-anchor who later marries him. Kathleen Quinlan appears as Dr. Shane, a psychiatrist treating Emma Pillsbury. Cooter Menkins, a football recruiter played by Eric Bruskotter, came to McKinley in "The First Time" to scout football players for Ohio State, and is attracted to Coach Beiste, whom he later marries.
NYADA and New York City 
From NYADA, Whoopi Goldberg first appeared in the third season as Carmen Tibideaux, a dean from NYADA who comes to Ohio to preside over Rachel's and Kurt's auditions to the school, in the episode "Choke". She appeared again, including at the Nationals competition in Chicago, and has returned in the fourth season for scenes set at NYADA.
Kate Hudson appears as Cassandra July, Rachel's dance instructor at NYADA who, according to Falchuk, teaches "based on negative reinforcement". She was introduced in the season premiere for a six-episode arc, however, Cassandra only appears in five episodes: four in 2012 and one in 2013.
Dean Geyer performs the role of Brody Weston, a handsome NYADA junior who shows an interest in Rachel. Their relationship gets to the point that the two live together for a while, but they break up after Santana discovers that Brody is a gigolo.
Sarah Jessica Parker is introduced in the third episode as Isabelle Wright, who is Kurt's mentor at Vogue.com after having signed him on as an intern. She is appearing in a multi-episode arc.
British actor Oliver Kieran Jones first appears in "Sadie Hawkins" in a recurring role as Adam Crawford, a NYADA senior and the leader of the glee club Adam's Apples, which Kurt looks into joining when he starts classes at the school for the spring semester. Kurt and Adam subsequently begin a relationship. Kieran Jones graduated from LAMDA, a real London school similar to Glee's fictional NYADA.
