Troian Bellisario plays Spencer.

Spencer Hastings (Troian Bellisario) (Season 1 - present) is considered the "de facto head" of the group. Intelligent and extremely ambitious, she thrives for perfectionism in everything she does, in an attempt to live up to the high expectations of her parents. Spencer's biggest rival is her older sister, Melissa, and the two are constantly at odds. Their relationship is often strained by the fact that Spencer has a habit of crushing on, and later kissing, Melissa's boyfriends (first Ian, then Wren). She is the closest with Aria although she got along with the others as well.

Although they were close friends, Spencer resented Alison, who constantly threatened to reveal to Melissa that Spencer kissed Ian. The two of them often argued, as Spencer was the only one of the girls who was willing to stand up to Alison. On the night of Alison's disappearance, Spencer told Alison that they were done being friends, and that she was tired of being treated like Alison's property. However, it was Spencer who went looking for Alison when she heard Alison scream.

Wren and Spencer have a brief affair, which is cut short when Melissa discovers it and dumps Wren. Spencer later begins a relationship with Alex, a boy who works at Rosewood's exclusive country club, though a misunderstanding leads to Alex dumping her. Although initially suspicious of Toby, believing him to be A and possibly Alison's killer, Spencer begins to bond with Toby after she becomes his French tutor and is also framed by A. The two begin to date, against the wishes of their parents. Soon after, Wren returns to Rosewood as a resident at the local hospital, which causes Spencer great emotional confusion. A later forces Spencer to break up with Toby, after revealing that it is the only way to keep Toby safe.

A frames Spencer for Alison's murder, by planting evidence in Spencer's house. She also causes many problems for Spencer's romantic relationships, such as getting Alex to dump Spencer and forcing Spencer to break up with Toby. In addition to this, A feeds into Spencer's suspicions towards Ian and plays upon her rocky relationship with Melissa, in order to cause a rift between Spencer and the rest of her family.

Spencer discovers that Jason her half-brother; she is furious with her parents, believing they betrayed her by keeping it a secret. Spencer later gets drunk and kisses Wren, although he gently turns her down. Spencer attempts to reconcile with Toby, who refuses to speak to her or let her back into his life. However, after Mona's arrest, Dr. Sullivan reveals that it was Toby who convinced her to come back to Rosewood. Toby explains to Spencer that he pretended not to love her to keep them both safe, and the two kiss, reunited. Spencer and Toby make love in the 3rd season. Little does she know that Toby is a member of the A team.

Aria Montgomery

Main article: Aria Montgomery

Lucy Hale plays Aria.

Aria Montgomery (Lucy Hale) (Season 1 - present) is considered the "alternative" one of the group. She is more outgoing in fashion and what she sees as acceptable behavior. She moves back to Rosewood with her family after living in Iceland for a year. Before Alison's death, she and Alison discovered that Aria's father was having an affair with one of his former students, Meredith, who became his coworker at Hollis College. Alison encourages Aria to tell her mother the truth, but instead, Aria reluctantly agrees to keep her father's secret. In the book, Aria's brother Mike blames Aria for their parents' problems. In the TV series, he does not completely blame her, but still has psychological problems stemming from this. Mike's problems escalate until he attacks their mom. By the middle of Season 2, Mike appears to be doing better.

Considered the most artistic one of the group, Aria also tends to be the most outgoing of the girls. Her interest in being a writer is what really attracts her to Ezra Fitz upon their first meeting in a bar. She is unaware that Ezra is a teacher at Rosewood High School. Despite their attempts to stay away from each other once they realize their student-teacher relationship, they eventually give in to their Aria confesses to the girls that she is seeing Ezra, shocking them, but not.

Out of all the girls in Alison's old clique, Aria is the most secretive, rarely getting help dealing with her issues. Her crush on Noel was encouraged by Alison; the two later briefly dated, but their relationship was ended after Noel attempted to blackmail Ezra after discovering that he was dating Aria. When Jason comes back to Rosewood, Aria feels herself drawn to him and becomes conflicted between her feelings for Jason and Ezra. Ezra's ex-fiance, Jackie, also comes to Rosewood; Aria, jealous, attempts to push her out of Ezra's life once and for all.

A has tormented Aria the least out of the four girls, though A does expose Aria's father's affair and attempts to ruin Aria's relationships with both Hanna and Ezra after blackmailing Hanna into trying to set up Aria's mother so that she will discover Aria and Ezra are dating. Aria breaks up with Ezra because of Jackie threatening to tell Byron about their relationship and getting him fired, but they get back together. Once Ezra finds out that Jackie was the reason why Aria broke up with him, he asks her if she still trusts him, leading them to telling Byron and Ella about their relationship. This leads to Ezra getting punched by Mike. It is later told that Mike was sorry about what he did, and tells Aria that he only punched Ezra for fear of what their father would have done if he had not. Aria later tries to explain to Byron and Ella that she loves Ezra and he loves her, but they understandably still disapprove. But when Aria's old classmate Holden comes back to Rosewood, Aria tricks Ella and Byron into thinking that she and Holden are planning to go out. Aria later tells Ella that she and Byron may have gotten Ezra to leave Rosewood but they lost their daughter, too. She is shocked when Ella shows up at Ezra's apartment asking them to explain to her how their relationship "works".

Hanna Marin

Ashley Benson plays Hanna Marin.

Hanna Marin (Ashley Benson) (Season 1 - present) is the "diva" of the group, having taken Alison's place as the most popular girl at Rosewood in Alison's absence. Prior to Alison's death, Hanna was a bulimic girl who Alison frequently mocked for being overweight. Hanna often purges, as a way to make herself feel better.

Hanna's parents are divorced; she lives with her mother and feels betrayed by her father, who has remarried. Hanna does not get along well with her father's new wife and daughter, the latter with whom she has a rivalry. After experiencing financial hardship, Hanna's mother steals thousands of dollars from the bank she works at, which Hanna accidentally discovers and is forced to keep a secret.

Hanna's best friend before the series is Mona Vanderwaal; after Alison's disappearance, the two transformed themselves from losers to the most popular girls in school by losing weight and getting a new look. Though Alison was one of Hanna's closest friends, Hanna expresses relief at Alison being dead, having been hurt so often by Alison, and seeing how Alison hurt everyone else. At the start of the show, Hanna was dating Sean, who she had crushed on for a long time, however, they break up as Hanna becomes more focused on the mystery surrounding A and Alison's killer. She later becomes close to Rosewood's resident bad boy, Caleb, and the two begin to date, with Hanna subsequently losing her virginity to Caleb. Although Hanna dumps him after she discovers Caleb was working for Jenna, the two later rekindle their relationship. Hanna is also friends with Lucas, who harbors an unrequited crush on her.

A frequently torments Hanna with taunts about her weight, and threatens to reveal her mother's theft from the bank. A also ran Hanna down with a car, after claiming that Hanna "knew too much"; the accident left Hanna with a broken leg and ribs. Hanna ruined her father's wedding to Isabel but didn't stop the marriage because Ashley tells her that Tom still married Isabel in a private ceremony. Hanna finds out from Tom that Kate will be attending Rosewood because he is moving back to Rosewood to be closer to her along with Isabel and Kate.

In the second season finale we learn that Hanna's best friend is A (Mona Vanderwall) who is played by Janel Parrish. Hanna is devastated and cannot bear the fact that Mona tormented her and her friends. Mona is later in a mental institution for the torment. But later found out that Mona was faking

Emily Fields

Main article: Emily Fields

Shay Mitchell plays Emily Fields.

Emily Fields (Shay Mitchell) (Season 1 - present) is the "jock" of the group. A highly competitive swimmer, she is considered the star of Rosewood's swim team. Sweet and shy, she is also a lesbian, something that she takes great pains to hide for a long time. Although her parents initially struggle with her being gay, they eventually come to accept her for who she is. After Emily's mother moves to Texas for a while to be with her father (who is in the Army, stationed in Fort Hood, Texas), Emily goes to live with Hanna.

Of the four girls, Emily was the one who had the closest relationship with Alison, whom she was in love with. Although Alison frequently mocks Emily's romantic feelings towards her, she also professes a fondness for Emily, telling her that Emily is the only one who understands her and that Emily is her "favorite". Alison appears after Emily passes out from carbon monoxide poisoning, telling Emily that she knows A's identity, but is afraid Emily will be killed if she reveals it. It is unclear if Alison's appearance was a hallucination or reality.

Emm is immediately attracted to her new next-door neighbor, Maya, and they begin seeing each other. However, their relationship is broken up by Emily's mother, who disapproves and has Maya sent away when she discovers marijuana in her purse. When Emily returns to the swim team after a short leave of absence, she becomes rivals with Paige, who has taken Emily's place as being the best swimmer. She confronts Paige about Paige's homophobia, only to discover that Paige is secretly gay herself (been trying to suppress her feelings for Emily that whole time). The two slowly reconcile and begin to date, though Emily breaks up with Paige, not wanting to be her "secret". In the second season, Emily starts dating Samara, whom she meets through a LGBTQ group, though she is dumped after a misunderstanding caused by A. Shortly after, Maya returns to Rosewood, sparking Emily's hope of renewing their relationship.

A singles her out as the "weakest link", forcing Emily to make up a lie about getting a college scholarship for swimming and tormenting her emotionally and physically, putting her under enormous pressure, which leads to Emily developing a stomach ulcer which is caused by stress. A also secretly dosed Emily with HGH, by putting it in Emily's body cream which she had been using frequently, which ends up on her medical record and destroys her chances of being able get a scholarship.

Emily reunites with Maya, but their new relationship is shaky. When Maya disappears, Emily is distraught, believing Maya has run away to California to stay with some friends. However, it is revealed in the second season finale that Maya has been murdered (presumably by A or another accomplice), her body is found behind the DiLaurentis house. Emily breaks down at the news, inconsolable.

Alison DiLaurentis

Alison DiLaurentis (Sasha Pieterse) (Season 1 - present) was the "queen bee" of Rosewood and the leader of her clique. Ruling the group with an iron fist, the vicious but charismatic Ali went missing during a slumber party at the end of summer. When Aria, Hanna, Spencer, and Emily begin receiving threatening messages from "A" a year after Ali goes missing, they think she is alive and is playing a trick on them. However, shortly after the appearance of "A", Alison's body is found buried in the backyard of the former DiLaurentis house, hidden under the gazebo (which had been under construction at the time of her disappearance). The discovery of her body launches a murder investigation. The police believe Alison was killed by a blow to the head (with a shovel), but the girls later learn, via Alison's autopsy report, that she actually suffocated to death by being buried alive.

It is revealed through flashbacks and clues sent by "A" that numerous people in Rosewood would have had motive to kill her. Alison was aware of all of the girls' deepest secrets: Spencer kissing Ian (her sister, Melissa's, boyfriend at the time), Aria's dad's affair with a student, Hanna's bulimia, and Emily's homosexuality (and her crush on Alison herself). She was also responsible for blinding Jenna, by setting off a fire cracker in Toby's shed with the girls with her; Ali blackmailed Toby into taking the blame by threatening to reveal that Toby and Jenna were engaged in a sexual affair (though it's later revealed that Jenna was blackmailing Toby into sleeping with her). Before her death, Alison had also been secretly dating Ian and being stalked by an unknown person who threatened to torture her the way she tortured everyone in Rosewood.

"A"

"A" is the main antagonist of the series.

On occasion "A" has been known to act as a less sinister character, such as when she/he saves Spencer from being attacked by Ian. Dr. Sullivan, the girls' therapist, was able to determine A's identity when "A" became her client for a short time, but in some unknown way, "A" figured out how to keep Dr. Sullivan quiet. It is unclear as to how much "A" actually knows about Alison's death. "A" was in possession of a video Ian had filmed of himself and Alison engaged in an affair and also provided the girls with Alison's autopsy report even though she/he took out a specific page leaving the girls wondering what information was on it.

The girls have suspected a few people of being "A": Toby (who was framed by "A"), Ian (who was killed by "A"), Jason (Alison's older brother), Noel, Garrett, Lucas, Jenna, and Melissa. A could be Alison's killer. It was revealed in a prequel episode of the Halloween before Alison went missing that she was also being tormented by "A" as well.

"A"'s identity is Mona, which was revealed at the end of Season 2. But the directors clue in that maybe she wasn't the only one sending texts and tormenting the four girls. At a dance the girls figure out who " A" is. Mona goes with Spencer to the motel where "A" has a secret hide out. When Mona goes to " get gum out of the car" she comes back as "A". Spencer is freaked out and doesn't have time to react before Mona smacks her. Mona then gets her in the car and tells Spencer that she has two options join the "A" team or disappear like Dr. S did. Spencer is called by the other girls and answers it without Mona knowing. Hanna, Emily, and Aria hear everything Mona said. They then see where she is taking Spencer and Aria knows a short cut. The girls all get there at the same time. Mona then realizes what happens and attacks Spencer. The girls fight Mona and push her off the cliff into bushes. The police arrive soon and so does Dr. S. She tells the girls that she would have never come back if it wasn't for Toby convincing her. Mona is then put into a mental hospital . But the girls are not done with "A" yet. In the third season, a new "A" started sending messages. This time "A" is more dangerous sending teeth to Emily and other things that were buried in Allison's grave to the Liars. "A" has a more sinister agenda. The identity of the new "A" is Toby, as revealed in Season Three, Episode 12. Mona, the first person revealed as "A", is talking to the new "A". When the new "A" turns around, its face is shown as Toby.

After the breakup, Melissa rekindled her relationship with Ian and the two eloped, after which Melissa confided in Spencer that she just wanted the fighting between them to stop. Shortly after marrying Ian, Melissa becomes pregnant, which again causes a rift between her and Spencer, who suspects Melissa is covering for Ian. When Ian goes missing, Melissa refuses to believe Spencer's claims that he is dead, thinking that she is receiving text messages from Ian, who is in hiding. After discovering Ian's body, however, Melissa becomes depressed and apologizes to Spencer for choosing Ian over her. When Melissa finds Ian's phone in Spencer's bag, (although it was A who put the phone in there), she believes it was Spencer sending the texts to Melissa's phone and mentions she will never, ever forgive Spencer for this. Melissa discovers that Jason is their half-brother and says that she can't be around their parents because they lied to her and Spencer. She still loiters around the house however, and Spencer and her friends begin to suspect that Melissa knows more about "A" and Ali's disappearance than she is letting on. They find a video taken inside Alison's room the night she disappeared, and Melissa is shown throwing open the door and yelling "Where is she?!" The girls also find out that Melissa was sending Ali threatening text messages, and had worked at a law firm that Ali had suspected of assisting "A" in messing with her life.

Even though Hanna stopped Isabel's wedding to her father, Kate still becomes Hanna's stepsister when their parents get married at the courthouse. Tom later moves back to Rosewood with Isabel, and Kate is enrolled at Rosewood High.

Janel Parrish plays Mona Vanderwall.

• Mona Vanderwaal (The spelling is changed from the book.) (Janel Parrish) (Season 1 - present) is a former unpopular girl at Rosewood who longed to be accepted into Alison's group and was continuously mocked by Alison. After Alison's disappearance, Mona befriended Hanna and they underwent an "extreme makeover" together; as a result, they both became popular students. She enjoys bullying Lucas, calling him "Hermie," much to Hanna's annoyance, so she stands up to Mona after Mona says, "Of course he wants to see a tornado; he wants to get to Oz so he could ask the wizard for a penis" in the episode "The Perfect Storm." After the appearance of A, Mona notices that Hanna is now acting strangely, and feels jealous that Hanna has rekindled her friendships with Aria, Emily, and Spencer. She dislikes Caleb and makes attempts to break Hanna and Caleb up, even asking Lucas for help (though he declines). Mona is somewhat romantically involved with Noel, which Hanna disapproves of. Although Noel breaks up with her, Mona acknowledges that Hanna was right about Noel. Mona knows the existence of "A" as she too is now a victim of "A". "A" threatens to put Mona in jail for stealing, unless she puts Hanna's police file public for all of Rosewood to see. Mona doesn't do so and instead returns the necklace she stole back to the jewelry store where she was confronted by the cops and was ordered to do community service by working in a soup kitchen. Despite this, Mona is still being threatened by "A". Hanna decides it's best if Mona hangs with her and the others for protection from "A". On the last episode of Season 2 it is revealed that Mona is "A" . . . or one of multiple "A's". She ends up having a mental breakdown and threatens Spencer by giving her the option of either "joining the A Team" or "disappearing" via Spencer's father's gun (Mona admits that she was the one to steal it from his desk). Mona shifts into an even more enraged frenzied state when Hanna, Aria and Emily show up (Spencer alerted them via her cell phone) and attacks Spencer which results in Mona falling off of the nearby cliff. When Dr. Sylvan, the girls' therapist arrives, Hanna breaks down crying, shocked that she was best friends with "A." Mona survives, but is committed to a mental hospital and is diagnosed with an antisocial personality disorder coupled with her high intelligence (she was living in a state of "hyper reality" where everything revolved around her). . . which explains how she was able to be aware of everything going on all of the time while acting ditzy and superficial (she also was recording all of Hanna's cell phone conversations and had easy access to the girls' personal dwellings). At the end of the episode, Mona is visited by a mysterious stranger (dressed in a red coat) in the mental facility and admits she did everything that she was "told to do". This implies that Mona is just one of many "A's" and there is someone else calling the shots.

• Lucas Gottesman (Brendan Robinson) (Season 1 - present) is an unpopular student at Rosewood, who harbors an unrequited crush on Hanna, who he develops a friendship with. More than once he expresses his happiness at Alison's death, having been continuously tormented by her, as she constantly called him "Hermie," believing that he really was a hermaphroditic, and Mona soon fallows in Ali's footsteps, frequently mocking him. He destroys the girls' memorial to Alison, stating that it isn't right that Alison's cruelty should be forgiven just because she died. It is hinted that Lucas was the unknown person who was stalking Alison prior to her death. Hanna forms a friendship with Lucas, and "A" gets her to lead Lucas on at a dance. Although initially angered by Hanna's rejection of his romantic feelings, he eventually forgives her and eventually goes so far as to bring Caleb home to make Hanna happy. He asks Hanna for dating advice after he becomes involved with a girl named Danielle. Lucas is later suspected of either being A or working with A, which causes a frightened Hanna to lash out at Lucas in self-defense. Soon afterward, Hanna and the others are convinced of Lucas merely being the victim of a misunderstanding and several coincidences (but an implication is made of the real A taking advantage of their suspicions of Lucas). The friendship between Lucas, Hanna, and Caleb appears intact. However, at the masquerade at the end of season two, we see Lucas hanging out with some suspicious people. At the end of Season 3 Episode 2, the jacket tag says large, which means that it's probably for a man (Lucas?) and its for The "A" group.

Maya assures Emily it is, but "It seems like he just won't take no for an answer," which surprises Emily as Maya said "he." This might possibly hint that Maya is bisexual.
