Mordecai (voiced by J.G. Quintel) is a tall, thin, anthropomorphic blue jay who works as a groundskeeper at The Park. He has been best friends with Rigby ever since childhood, and together they are very lazy and constantly slack off at their jobs there. Mordecai is more conscientious, mature, and moral about his actions than Rigby is, which sometimes leads to his opposing Rigby when he is the cause of some kind of chaotic problem. However, Mordecai usually sides with his friend and the two generally stick together through their adventures. Mordecai loves to play video games and is a better player than Rigby. He can sometimes become caught up in his emotions, often letting them get the better of him. However, he is usually quick to apologize to others if he has hurt them and occasionally takes the lead in fixing a situation. He had a crush on Margaret Smith, a red robin who worked as a waitress at a local coffee shop. Mordecai would often hang out with her, along with Rigby and Eileen Roberts, and made many attempts to try to start a relationship with her. The two finally begin to date in the fourth season until Margaret decides to leave for college, thus ending their relationship. He decides to take a break from dating in "Dumped at the Altar", after his relationship with CJ didn't work out. In the episode "Camping Can Be Cool", it is revealed that he attended art school before being employed at The Park; however, he never finished the course due to his bad portrait skills, which were revealed in the episode "Bad Portrait". He is shown to have an uptight mom, who embarrasses him around his girlfriends and also made a highlight reel of Mordecai's most embarrassing moments, as seen in "Maxin' and Relaxin'". In the epilogue to "A Regular Epic Final Battle", Mordecai quits The Park and returns to making art. He opens a successful exhibition and meets a bat woman whom he marries and starts a family.
Rigby (voiced by William Salyers) is a short, anthropomorphic brown raccoon who works as a groundskeeper at The Park. He has been best friends with Mordecai since childhood and slacks off even more than Mordecai does. Rigby is hyperactive, immature, and extremely mischievous, which sometimes puts him at odds with Mordecai. He mostly lives for simply having a good time and relaxing, which he sometimes achieves through selfish acts like lying or cheating. He has a bad habit of getting himself and others in trouble, often causing many of the chaotic and surreal problems that arise in The Park. Nevertheless, he is shown to be a good person deep down and sticks closely to his friends. Like Mordecai, Rigby loves to play video games, but he is the worse of the two. He is also shown to be the weakest of The Park workers, although he has surprised them on a few occasions. Rigby's lack of strength was a major plot point in the episode "One Pull Up," in which Rigby had to pass a company physical and keep his job by performing one pull up. He has a younger brother named "Don", whose height and physique lead people to believe that he, not Rigby, is the older brother. Eileen Roberts, a female mole who works at a local coffee shop, previously alongside Margaret Smith, has strong feelings for Rigby and makes this very obvious. He originally did not reciprocate her feelings and harshly ignored her at some points, but he quickly begins to warm up to her and implies that he likes her, as well. In "Dumped at the Altar", Rigby reveals to Mordecai that he and Eileen have been dating for months. Rigby is allergic to eggs, as evidenced in the episode "Eggscellent" when Rigby tried to eat a 12-egg omelet to win a trucker hat and went into a coma due to a severe allergic reaction. Rigby has also died four times and was resurrected in the series. He was killed by Skips in an arm wrestling match, he was killed by Snowballs the monster, he was killed by Mordecai who pushed him into the Space-Time Continuum, and fell into a fatal coma in "Eggscellent". As of Rigby's Graduation Day Special, Rigby is finally graduated from high school. In the epilogue to "A Regular Epic Final Battle", Rigby quits The Park and moves in with Eileen. They start a family, but it's unknown if Rigby is working or not as he is seen teaching his children how to play video games.
Benson Dunwoody (voiced by Sam Marin) is a living gumball machine who works as the manager of The Park. He is frequently infuriated with Mordecai and Rigby due to their constant slacking and mischief. He is very hot-tempered and prone to fits of rage, often turning red (or pink if injured) whenever he yells or is extremely angry, he has catchphrases are "You're Fired!", "[blank] or You're Fired!", or even "Get Back to Work!". At the end of some episodes, Benson tries to fire them, but Rigby and Mordecai always managed to find a way to keep their jobs with some help from other characters. Despite always being at odds with them, Benson is ultimately friends with them after calming down a bit in the episode "Benson Be Gone" and the three gain more insight and trust with each other as the series progresses. In the episode "Think Positive", it is revealed that Benson's family members often yelled at each other when he was a child. His father instructed him that he would not get anything in his life if he did not speak up for it. If Benson ever contained his anger for too long, the anger inside him will cause havoc and destruction unless he expresses his anger by yelling (often at Mordecai and Rigby). It has been implied that Benson was unhappy during his youth and did not enjoy his family's anger. He is skilled at stick hockey and has a strong love for music, proving to be an extremely skilled drummer in the episode "150 Piece Kit". Benson used to date Audrey, a human woman who lives across from him in his apartment complex. It is revealed that they broke up in "The Real Thomas", in which Benson starts to date an undercover Russian spy named Natalia, although she is later eaten by a whale. In the episode "Pam I Am ", Benson develops feelings for one of the dome scientists named Pam and they go on a 'date'. However, Dr. Langer witnesses the 'date' and makes a new rule that forbids the dome staff from dating anyone who works at the park. At the end of the episode, it is implied that Benson and Pam will date once the dome is gone. During the beginning of the episode "Fries Night", Benson contacts Pam back on earth, to which she revealed that having a "long distance" relationship with Benson because he is now in space is too difficult for her. She states that the reason for the break up is that she doesn't know when or if he will ever return to earth again. They both agree to become friends even though Benson later gets depressed from yet another break up with a woman he really cared for. In the epilogue to "A Regular Epic Final Battle", Benson remains working as the manager of The Park and gets back together with Pam. They apparently adopt Apple Sauce as well as a variety of cats.
Pops Maellard (voiced by Sam Marin) is a cheerful, quirky, and naïve lollipop-shaped man who resides at the house in The Park. His adoptive father, Mr. Maellard, is the owner of The Park. Pops tends to be very ecstatic about everything, often exclaiming "Good show!" or "Jolly good show!" when he is happy about something. When something bad happens, he will instead say "Bad show." He carries small lollipops in his wallet, sincerely believing that they are real money, much to everyone's confusion. He is an upright gentleman who is very kind and well-mannered to everyone. He is also very sensitive, often becoming upset or crying if his feelings are hurt. He has strong interests in poetry, wrestling, music, nature, animals, and games. Despite being an elderly man, he is very childlike and is often oblivious to serious things around him. Because of this, the group is frequently looking after him, especially Benson. In the episode "Prank Callers", it is shown that Pops was once a more serious and mature man back in the 1980s. However, when Mordecai and Rigby had been sent back to that time and accidentally hit him with a golf cart, he is shown to have turned into his zany self. Pops once owned a British doll named Percival, or Percy, who turned his back on him and tried to kill Pops in "Terror Tales of the Park". Pops is also one with nature, but lost it until he tries to find the answer to get it back, as shown in "Catching the Wave". In Season 8, Pops is revealed to be the universe's Chosen One due to being born with telekinetic abilities and ever since he is one with nature back in some previous season's episode, as well as having an evil version of himself with the ability to erase a person from existence. Pops' destiny is to kill Malum Kranus to prevent the destruction of the universe. In "A Regular Epic Final Battle", it is revealed that his real name in Mega Kranus. Pops also realizes that the best way to defeat Malum Kranus is with kindness. Pops gives Malum Kranus a hug and the two fly into the sun, killing them both in the process, and the universe is saved. In a sort of heavenly paradise, Pops' is heard saying his catchphrase 'Jolly Good Show' as a video tape of the show, and the show itself, ends.
Skips (formerly Walks) Quippenger (voiced by Mark Hamill) is a yeti who works as a groundskeeper at The Park. He is the strongest and smartest of The Park workers and they almost always turn to him for help, as he usually knows how to solve the chaotic problems that arise in The Park, but he isn't always right. Whenever he is asked for help, he generally says, "I've seen this before", and then presents a solution. As his name suggests, he is always skipping rather than walking. He is a diligent worker and is very skilled at his job; however, he suffers from a lack of knowledge of computers and other kinds of newer technology, which was seen in the episode "Skips vs. Technology". Aside from this, he is very experienced and knowledgeable, as he is immortal and has been alive for hundreds of years. In the episode "Free Cake", it is revealed that he must perform a ceremonial dance every year on his birthday in order to renew his immortality. He explains the story of how he received his immortality in the episode "Skips' Story." He chose to become immortal in order to fight Klorgbane, an immortal bully who inadvertently caused the death of his girlfriend Mona, the only woman that Skips had ever loved. The Guardians of Eternal Youth provided Skips with his immortality, knowing that he was the only one capable of defeating Klorgbane with the Fists of Justice. Skips' birth name was Walks, but he changed it to Skips when he received his immortality because he and Mona would always skip when they were together. This is also the reason why he always skips instead of walking; he chose to do this in order to remember the times he and Mona shared for all his life. Skips also plays a bass guitar, which was revealed in a few episodes. In the epilogue to "A Regular Epic Final Battle", Skips remains working at The Park, satisfied with his life.
Mitchell "Muscle Man" Sorenstein (voiced by Sam Marin) is a short, obese and green-skinned man who works a groundskeeper at the Park. He is very erratic and immature, often pulling pranks and joking around. He enjoys telling "My mom!" jokes, botched attempts at "yo' momma" jokes, much to the annoyance of everyone except Hi Five Ghost, his best friend. Although he can be rude due to his ego, he is ultimately shown to be polite and caring toward his friends. He and Fives were fired in the episodes "Don" and "Under the Hood" but were rehired at the end. At times, he can burst out on a rampage if he is greatly angered. His father, Muscle Dad, enjoyed the same attitude for pranks and jokes, but died in the episode "Trucker Hall of Fame". His older brother, Muscle Bro (real name John), is also seen throughout the series. Muscle Man originally shared a rivalry with Mordecai and Rigby throughout the first two seasons, but the three started to get along and treat each other as friends from the third season onward. His girlfriend, Starla, shares a similar appearance to him and the couple constantly disgust other people when they publicly kiss and show affection to each other. His real name was revealed to be Mitch Sorenstein in the episode "Muscle Woman". In the episode "Power Tower", it is revealed that he gained the nickname "Muscle Man" from his early years of bodybuilding and actually being in excellent physical condition, but he found that life very boring and gave it up. In "The End of Muscle Man", he proposes to Starla and the two become engaged and they are now married in "Dumped at the Altar". In the epilogue to "A Regular Epic Final Battle", upon returning home Muscle Man discovers he has a three year old daughter. He and Starla live out their days in their trailer park home and have numerous children.
High Five Ghost
High Five Ghost (voiced by J.G. Quintel) is a small ghost with a hand extending from the top of his head who works as a groundskeeper at The Park. High Five Ghost is best friends with Muscle Man and frequently gives him high fives to accompany his jokes, as he genuinely finds most of Muscle Man's jokes amusing. Because of his name and appearance, he is frequently called by his nickname, "High Fives". High Five Ghost rarely speaks throughout the first three seasons of the series, but he is given more dialogue from season four onward. His father was introduced in the episode "See You There", as well as his older brother, Low Five Ghost, who works as a police officer. In the episode "The Postcard", High Five Ghost reunited with a human girl named Celia whom he had befriended after waiting four years to receive a postcard from her. In the epilogue to "A Regular Epic Final Battle", High Five Ghost and Celia become a married DJ duo and tour the world together. They too, have a child.
Eileen Roberts (voiced by Minty Lewis, a writer/storyboard artist for the series) is a shy and timid mole who works at a local coffee shop, previously alongside Margaret. She has a crush on Rigby, but he initially found her annoying. She first appeared in the episode "Brain Eraser". She also appears in the episode "Do Me a Solid", in which Rigby learns of Eileen's crush on him (even though Rigby shows no interest in Eileen), though he goes along with it for a while. Since the episode "Camping Can Be Cool", Rigby has warmed up to Eileen. Rigby thought very highly of her and praised her actions throughout the episode. In the episode "Diary", Rigby admits that he finds Eileen to be attractive when she is not wearing her glasses, but it also reveals that she also can't see without them. In the episode "One Pull Up", Eileen helps Rigby train for his company physical and he shows his gratitude by hugging her (and crushing her due to his enlarged physique). In the episode "Eileen Flat Screen", it is revealed that Eileen and Rigby have been spending more time together. In "Dumped at the Altar", Rigby tells Mordecai that he and Eileen have been dating for two months. In "Rigby's Graduation Day Special", Eileen finally graduates from college, in the same time Rigby finally gets his high school diploma on his graduation. While cooking for a graduation party for her and Rigby as the guys uninitially pressing the button that can send them and the park to space, Eileen is currently stuck with the guys. As of Season 8, Eileen is currently the new main characters member. In the epilogue to "A Regular Epic Final Battle", she and Rigby move in together and start a family. It is unknown if she has a job or not, but based on her husband's lazy personality, it can be implied that she does.
Nikolai (seasons 4–7) (voiced by Roger Craig Smith) is a young goat who was trained by the KGB as a ruthless spy, who later sent him to work for the Russian organization M.O.M.M. (Ministry of Mental Management), a company whom struggled to find out what made American parks up to date and wealthy. In order to fix the country's outdated parks, the company sent out Nikolai on a covert operation to obtain the park and bring it back to Russia. During his undercover mission, he changed his identity to "Thomas" and presented himself as a newcomer in "Exit 9B" (in which he made his debut), working as an unpaid intern who calls his "mom" on a regular basis and is often reproved by his coworkers, most notably by Muscle Man. He is also usually reluctant to be involved in the surreal and chaotic adventures that arise in The Park, often asking if he has to be part of the situation, to which they insist that he must. There are times, however, when Nikolai becomes personally invested in maintaining his cover, such as using a robot to pose his "mom" in "The Thanksgiving Special" and wearing spy attire disguised as a Halloween costume (a slice of pizza, which he had to wear until Thanksgiving Day upon losing a bet in "Terror Tales of the Park III"). Eventually, he reveals his true identity to the park crew and why he's really working there in "The Real Thomas", when the other Russian spies that were deployed with him carry out the final phase of the plan to bring The Park to Russia. But when Nikolai learns the plan is really to destroy the Park through a loophole in Russian/American relations, he turns on his fellow spies for being lied to (along with some persuasion by the park crew to remind him of the good times they had as friends, despite the constant poor treatment he received from them for being an intern), and returns the Park to American soil before going on the run from both sides. He makes several cameos after this, usually in some sort of disguise. Eventually, he returns in "Guys Night 2", revealing himself to be tired of his old life as a spy and wants to move on to a new life, in which his only option is to go hiding forever, but has one final hang with the park crew. He would later make non-speaking cameos in later episodes.
Margaret Smith (voiced by Janie Haddad-Tompkins) is a female red robin who was a waitress at a local coffee shop. She was good friends with her co-worker, Eileen. Mordecai had a huge crush on Margaret and frequently found excuses to go to the coffee shop to see her. She has a cousin named John who has an artificial wooden leg. The rest of her family are all birds like her and Mordecai, except for her father Frank, a strong and stern human. Margaret returns Mordecai's feelings for her and the two begin to finally date in the fourth season. They broke up in the finale when Margaret leaves for college. In the episode "Eileen Flat Screen", Margaret returns now as a news reporter, which no one notices. In "Merry Christmas Mordecai", Mordecai becomes nervous when he hears that Margaret will be there. After several awkward encounters (thanks to Mordecai), they finally manage to have a normal conversation with both acknowledging that they had some good times. This leads to a montage of memories, ending with a kiss on a roller coaster. Unfortunately, when the scenes flashes to the present, they accidentally kiss on the lips and are shocked when they notice CJ watching them. CJ runs out of the house and leaves while Mordecai runs upstairs to find his phone; he notices that all of Margaret's stuff is there and Eileen tells him she is staying as an intern. Mordecai is frantic when he hears the news and didn't know what to say about Margaret staying with Eileen from now on.
As of "Sad Sax", Mordecai and Margaret are still just friends, and Mordecai makes it up to CJ by telling her the honest truth.
In "1000th Chopper Flight Party", Mordecai is still awkward with her presence and afraid to screw up, even to the point of letting Rigby constantly mess up the Party as a diversion just to keep her away from him. When he finally is declared as the lucky guest to ride Chopper 6 for its 1000th flight, he finds it hard to say no and joins. Margaret tries to talk to him, but Mordecai awkwardly resists until she scolds him for his attitude in desire for their friendship. Mordecai then lifts the tension with a joke and they finally start to have a fun chat. This however angers CJ, who misinterprets it as them rekindling their love, and she causes havoc with her storm cloud ability. Mordecai tries to save Margaret, but she calms CJ when she reveals that she is in a relationship with news anchor, Del Hanlon, which stuns Mordecai and surprises her parents.
In "Not Great Double Date", He seemed upset that Margaret appeared to have a boyfriend for herself, but still said that she seemed happy with Del and that he liked him. When she confessed that Del was not her boyfriend and that she was tired of feeling like a tourist around her friends because of the tension with CJ, he felt sad about it and was pretty interested to know that she still had feelings for him.
In "Just Friends", Rigby and Eileen go to the presentation of martial arts Don therefore Mordecai and Margaret spend a night that coincidentally has romantic moments. A chef named Daisuke shows them their future using magical sauce. It is revealed that if and when Mordecai and Margaret get together, they will get married, have children, buy their own houseboat, and die peacefully after 50 happy years. Mordecai and Margaret agree that their future looks like it will be really great, but that they are still young and should take it easy on relationships. At the end of the episode, the two agree to remain just friends, with future Margaret looking down on them and inquiring how long they can be just friends, and future Mordecai stating that "only time will tell."
In "Rigby's Graduation Special", she was very worried as she watched Mordecai and the other park workers were shot into space, even saying his name in concern.
However, in the epilogue to "A Regular Epic Final Battle", she is seen only greeting Eileen when she returns. She does not end up with Mordecai and is not seen with the group 25 years later, though one can imply that they are still good friends.
Audrey (voiced by Courtenay Taylor) is Benson's ex-girlfriend and neighbour who appears in "Weekend at Benson's", "Fortune Cookie", "The Christmas Special", and "Party Re-Pete". It is revealed in "The Real Thomas" that they broke up.

In the episode "Muscle Woman", she developed a crush on Mordecai and had previously dated two other people as indicated by a tattoo on her lower back. When Mordecai broke up with her, she became extremely angry, destroying everything in her path, including a helicopter. She got back together with Muscle Man after he expressed his feelings towards her at the end of the episode. Since then, Starla has appeared with Muscle Man in various episodes, including "Fancy Restaurant", "Pie Contest" and "Bald Spot". In the episode "The End of Muscle Man", Muscle Man proposes to Starla and the two become engaged. In the episode "Dumped at the Altar", she marries Muscle Man. In the epilogue to "A Regular Epic Final Battle", Starla is revealed to have had a daughter during the crew's three year absence.
Mr. S. Maellard (voiced by David Ogden Stiers) is an elderly lollipop man who owns The Park and is also Pops' stepfather. He first appeared in the episode "Dizzy". Maellard is very impatient towards Benson (similar to Benson's impatience towards Mordecai and Rigby) and Maellard blames Mordecai and Rigby's shenanigans on Benson (as he expects Benson to take responsibility for Mordecai and Rigby as park manager). He purposely mistakes Benson's name a lot in some of the episodes in which he appears (using "Ballbucket", "Beanbag", etc.). Maellard finally got Benson's name right (and started to respect him more as well) in the episode "Benson Be Gone" due to Benson's coming to his rescue when he was captured by Susan (a woman whom Mr. Maellard had hired as the park manager after demoting Benson and is later revealed to be a demon) and also gave Benson his old job back. As the series progresses, he turns into quite an eccentric character. He sends the gang to space in the final season and in the episode "The Ice Tape", Pops and the gang find out that Maellard is not his real father but Maellard found him as baby and adopted him during an expedition and kept him safe until the time was right for Pops to fulfill his destiny but Maellard tells Pops that no matter what he always thought of him as his real son. In the season finale, after the park gang return from space for three years in 25 years later, he apparently died in natural cause.
Cloudy Jay "CJ" Love (voiced by Linda Cardellini) is a cloud humanoid. She had been Mordecai's girlfriend with reoccurring anger problems. She first appeared in the episode "Yes Dude Yes", in which Mordecai started dating her after thinking Margaret was engaged. After learning that Margaret was not getting married, he almost immediately forgets about CJ, leading to an ugly break up at the coffee shop in which she revealed that she can transform into a deadly storm when really angry and assumed this form in three episodes. After Margaret leaves town for college, CJ and Mordecai meet each other at the New Year's Eve dance in the episode "New Year's Kiss", unwittingly kissing each other at midnight. The following episode, "Dodge This", continues this story days after the kiss with CJ and Mordecai competing against each other in a dodgeball tournament. This leads to awkwardness between the two in the final round of the dodgeball tournament and they are forced to address their issues before the Intergalactic Dodgeball Council. They later agreed just to be friends. At the end of the episode "I Like You Hi", Mordecai asks CJ out and she agrees to go out with Mordecai. In the following episode, "Play Date", CJ and Mordecai plan to go out, but are interrupted by Death's 300-year-old son, Thomas. In the Season 5 finale "Real Date", Mordecai saves her life when the founder of Couple Corral McIntyre tries to get them to break up and they officially become a couple. In "Merry Christmas Mordecai", she sees Mordecai and Margaret accidentally kiss, and drives off very upset. In "Sad Sax", Mordecai tries to reconcile with her after receiving advice from "Sad Sax Guy", and they finally get back together. In the episode "1000th Chopper Flight Party", she screws up and ruins their relationship, and she and Mordecai break up in "Dumped at the Altar".
The Baby Ducks (voiced by J. G. Quintel, William Salyers, Sam Marin, Mark Hamill, and Roger Craig Smith) are a group of four ducks whom Mordecai and Rigby found in a fountain in the park in the episode "A Bunch of Baby Ducks". They have shown their ability to fuse together to form a giant, anthropomorphic, duck-like creature when they fist-pump simultaneously. They return in the episode "A Bunch of Full-Grown Geese" to help Mordecai and Rigby rid the park of the evil, titular geese who soon turn into a giant monster. The duo helped the baby ducks upgrade their giant form and succeeded in defeating the geese. They also appeared in "Exit 9B" where they helped fight the park worker's past villains in their giant form. Before their official debut, a group of baby ducks are some of the things sent to the moon by Rigby in the episode "The Power". In the final season finale, they help the Park gang fight Anti-Pops and Streaming.
Guardians of Eternal Youth
The Guardians of Eternal Youth (voiced by David Kaye, Robin Atkin Downes, Roger L. Jackson, J. G. Quintel, and Troy Baker) are a group of five infant-like beings for whom Skips must perform a ceremonial dance in order to maintain his immortality. Skips also attended school with them before they granted him his immortality. They also designed and built Skips' Fists of Justice, which allowed him to defeat Klorgbane the Destroyer (their evil brother) in the episodes "Fists of Justice" and "Skips' Story" and they seem to like cake. Mordecai and Rigby found out about this and because they accidentally injured Skips, they took over and defeated Klorgbane (but not before he killed Archibald, one of the guardians), who vowed to return before he was sent flying away. They also appeared in "Exit 9B", where they help the park workers fight off their past villains. In the episode "Quips", the leader's name is revealed to be Reginald, and in "Skips' Story", the names of the other three guardians are revealed to be Oswald, Boswald, and Griswald.

He works as a valet for the Guardians and also made an appearance in the episode "Cool Bikes" where he served as Mordecai and Rigby's lawyer. In "Gary's Synthesizer" it is revealed that he has an old synthesizer that keeps him alive, but if it comes unplugged he will disappear. He is the king of his home planet Synthos, but left to travel the galaxy and his half-brother David took over. When he found out how strict David is as king of Synthos, he battled him in a music battle and won. David was destroyed in the sun and his disk was smash by two Synthos people Robert and Keith who hated David. Then Gary declared that from now on Synthos will have no ruler. In the final season finale, he helps the park gang fight Anti-Pops and Streaming.
Death (voiced by Julian Holloway in a cockney accent) is a grim-reaper who tried to take the immortal life of Skips during his first appearance in the episode "Over The Top". He also tried to take Muscle Man's soul twice in the episodes "Dead at Eight" and "Last Meal" and even tried to take everyone's souls in "Skips Strikes". However, he also helped the groundskeepers defeat Garret Bobby Ferguson's villains in the episode "Exit 9B". Death has a son named Thomas (voiced by Michael Dorn), a 300-year-old demon. He later helped them retrieve Maellard's guitar in "Guitar of Rock". He later appears in "The End of Muscle Man" where the others think he's trying to take Muscle Man's soul, but was only there to deliver him a ring. In the final season finale, he helps the park gang fight Anti-Pops and Streaming.
Don (voiced by Julian Dean) is Rigby's younger brother. Introduced in the episode "Don", Don is better and more likeable than Rigby in most ways, though as a child he was trying to be as cool as Rigby, unknowingly causing Rigby to be extremely jealous. Don is also significantly taller than Rigby, and loves to give hugs to other people. At the end of the episode, the two reconcile as Rigby apologizes to Don on his jealousy towards him, while Don apologizes for not knowing of Rigby's annoyance towards him. Don returned in the episode "Bank Shot", where he helped Rigby practice for a bet he made with someone Don makes a final appearence in the finale where he and his paents greet rigby home after 3 years.

He later appeared to help Mordecai, Rigby, Hi-Five Ghost & Muscle Man get a car so they can get burritos with all kinds of meat.
God of Basketball
The God of Basketball (voiced by Carl Weathers) is a basketball/human hybrid who is also known as the Basketball Coach King. He apparently lives within the moon and rides in a custom designed white flying Cadillac Escalade. The God of Basketball then quickly befriends Mordecai and Rigby in "Slam Dunk" which leads him into offering them to learn how to play basketball well. When that does not go according to plan, he uses his powers to instantly grant both of them great basketball powers. The God of Basketball momentarily changes sides when he is forced to play with Muscle Man against the duo for computer rights for life. The God of Basketball also appeared when he helped Rigby to get back his hat, in the match of Rigby vs. a Basketball net face-like weirdo in 'Bank Shot'.
