Voiced by: Roger Craig Smith

Debuted in: Season 4, "Exit 9B"

The newest addition to the park, a billy-goat intern.

  • Affectionate Gesture to the Head: He is officially welcomed to the park staff with a group petting session.
  • Anti-Villain: Even after his reveal as a foreign spy, Thomas admits that he still likes the friends he made.
  • Ascended Extra: Actor example; Roger voiced dozens of minor and incidental characters prior to being added to the roster for good as Thomas.
  • Because You Were Nice to Me: Downplayed. While he is aware of how the Park employees could treat him like a Butt-Monkey, he also realizes they were nicer to him than the Russian government. As such, Nikolai betrays the Russian government to help his friends and save the Park.
  • Becoming the Mask: He considers the park staff his real friends, even though his work there was only his cover.
  • Berserk Button: He doesn't like to be called a mama's boy. Muscle Man learned that the hard way.
  • Beneath Notice: Why he poses as an intern.
  • Blank Slate: Given he has no specific character role yet, for some fans he tends to fall somewhere between this and The Everyman. Until he's revealed as The Mole.
  • Brick Joke: In the third Halloween special, the group have a story-telling contest where the loser has to wear their Halloween costume until Thanksgiving. He winds up losing and from that episode onward he's stuck in his pizza costume until the Thanksgiving special where he's finally allowed to take it off (and is in desperate need of a shower).
  • The Bus Came Back:
    • As a cameo, but he can be seen in disguise in the crowd during the reception in "Dumped at the Altar."
    • Ultimaley, he returns in "Guys Night II" to spend time with his park friends for the final time.
  • But Now I Must Go: After revealing he's a Russian spy, Benson offers him to stay at the park, but he declines since he'll be hunted down after betraying both the U.S and Russia and decides to go on the run.
  • Butt-Monkey: Mainly in "Starter Pack" and "The Christmas Special".
  • Chick Magnet: Surprisingly, in "New Year's Kiss", he is seen dancing with three girls at the same time. In "I Like You Hi", he mentions that he has at least four girlfriends.
  • Cloudcuckoolander: Shows a tiny bit of this in "Journey to the Bottom of the Crash Pit". He works the camera/video booth at the park, but says he "knows a guy" at the climbing equipment booth. "The guy" is still Thomas with a ballcap on, having walked a couple feet to the other booth.
    • In "Return of Mordecai and the Rigbys", when Mordecai and Rigby can't think of anything for Thomas to do, he decides to be their mean British manager because every band has one.
    • In "I Like You Hi", when Mordecai asks for advice from a panel of his co-workers for his problem, Thomas just names off some of his girlfriends' music preference and tells him to try it. Mordecai wonders why he's even in this panel.
  • Dark and Troubled Past: He was an abandoned child trained by the Russian government to be a ruthless spy.
  • Defector from Commie Land: He defects when it's revealed to him that his mission is supposed to destroy the United States, in addition to killing or enslaving the park staff.
  • The Dog Bites Back: In "Exit 9B", he gets fed up with how G.B.F. Jr. treats him so he threw iced coffee in his face before he is kicked off the freeway ramp. But then he is saved and he signs the document to save the park which foils G.B.F. Jr. plans.
  • The Drag-Along: Not always eager to be involved in the Park Crew's craziness. Such as saving Muscle Man's trailer, or fighting a rival park crew for a coffee mug.
  • Four-Temperament Ensemble: The Leukine - Pretty much The Generic Guy, until it's revealed that he is a spy.
  • Funny Animal: He's a goat who wears clothes.
  • Going Commando: Decides to do so to avoid getting wedgie'd by Muscle Man again.
  • Green Rooming: After his two introduction episodes at the start of season four, he ended up not appearing in any episode in a meaningful role (besides the Christmas special) until much later in "Cool Cubed", although a good chunk of that time is spent frozen.
  • Heel–Face Turn: After being revealed to be a Russian spy, he turns against Natalia and in effect Russia after she tried to enslave, and then kill the park crew, his true and only friends.
  • Initiation Ceremony: Mercilessly pranked as part of his hazing in the episode after he is introduced, by Muscle Man in particular. And even when he and Muscle Man prank Mordecai and Rigby, Muscle Man ends up destroying Thomas' car, which wasn't exactly part of the prank itself. Thomas gets screwed either way.
  • The Intern: Thomas is interning at the park as part of his college course. Or that's what he wants you to believe.
  • The Mole: He's an orphan raised by the KGB and sent to the park to study it.
  • One Steve Limit: Subverted, as Thomas (the goat intern) shares the same name with Thomas (the son of Death), which was lampshaded once. Double subverted, as the former's real name is Nikolai.
  • Only Sane Man: Only guy who routinely questions the bizarre antics the park crew get into.
  • Put on a Bus: He leaves the park in "The Real Thomas" due to being a rogue secret agent who is now a fugitive of both America and Russia. It's unknown if Thomas can make any kind of return given his situation.
  • Phrase Catcher: The rest of the park staff tend to angrily shout "Thomas!" whenever Thomas tries to get out of whatever crazy event they've gotten themselves into this week.
  • The Power of Friendship: He defects from Russia thanks to the park staff, whom he now sees as his only friends.
  • Took a Level in Badass: Who knew Thomas was strong enough to put Muscle Man in an arm bar in "Thomas Fights Back"? He also helps the group by pulling off a brilliant gambit as an undercover intern at the opposite park.
    • Turns out these awesome abilities are thanks to the training he had to become a KGB agent.
  • Walking Spoiler: The more said about him besides being an intern, the more of a spoiler he is.
  • Wham Line: (In his native accent) "I am Russian spy."
  • You Said You Would Let Them Go: He's genuinely shocked that Natalie tries to have the park crew killed after finishing their mission.

    Margaret Smith 

Voiced by: Janie Haddad

Debuted in: Season 1, "Caffeinated Concert Tickets"

A red-breasted robin who used to work at a coffee shop. Mordecai has a crush on her.

  • Affectionate Nickname: "Hug bug" from her father.
  • All Girls Want Bad Boys: The only time Margaret has shown to have an interest in Mordecai was when he "blew her off" (Mordecai at the time was suffering a Heroic BSoD from seeing Pops naked). Eventually inverted around Season 3.
  • Amicable Exes: Zigzagged with Mordecai. When they broke up with her returning and him being with CJ, it is awkward, as Mordecai has complicated feelings over seeing her again while being in an official relationship. Things gets more messier after they share a kiss. And while they have no ill will for one another, Mordecai's awkward nature initially causes some problems, but they manage to work it out.
  • Barefoot Cartoon Animal: In most episodes, though in some she does wear shoes.
  • Bare Your Midriff: Has her moments. One example in "Meat Your Maker", in Mordecai's dream where she wears a seashell bra.
  • Better as Friends: She and Mordecai eventually agree this in "Just Friends" and remain this way for the rest of the series.
  • Betty and Veronica: The girlish, calm "Betty" to CJ's tomboyish, hot-headed "Veronica" for Mordecai's "Archie". At first, Mordecai is with Margaret but they break up because she got into her dream school and he eventually starts a relationship with CJ. Although, due to Mordecai mixed signals which included him kissing Margaret despite being in a relationship with CJ has led to her getting hurt over and over again. Finally, when he attempts to make a Love Confession to CJ or Margaret at Muscle Man and Starla's wedding, they both decide to break up. And in regards to Margaret, both amicably agree they are Better as Friends.
  • Beware the Nice Ones: When she gets ticked off, she's surprisingly scary.
  • Black Comedy: If her story in "Terror Tales of the Park II" is any indication, she's got a messed up sense of humor.
  • Brainless Beauty: Had tendencies of this in early seasons, but has developed to be a little smarter and more reasonable. And she did get into college. So there's some modicum of smartness up there.
  • The Bus Came Back: At the end of "Eileen Flat Screen".
  • Characterization Marches On: Margaret was a Flat Character compared to the other recurring cast, that is until "Do Me a Solid" where she's revealed to be a down-to-earth character (the unusual circumstances don't faze her nearly as much as one would expect).
  • Daddy's Girl: It's implied, since her password for her phone is the trope name.
    • She also mentioned once that she used to play a lot of mini-golf with her dad.
    • Made canon in Family BBQ.
  • Damsel in Distress: In the Cartoon Network RS game, Fist Punch, where The Night Owl kidnaps her and Mordecai and Rigby has to save her.
  • Distaff Counterpart: To Mordecai. They were quite clearly designed to complement each other.
  • Dude Magnet:
    • For over half the series, Mordecai has an intense, barely hidden crush on her.
    • Prior to dating Mordecai, Margaret had three boyfriends.
    • Possibly during one of his break-ups with Starla, Muscle Man was checking out Margaret when he saw her run by the park.
    • The God of Basketball referred to her as a "hot chick".
  • Feather Fingers: She's a bird with wings, and she uses her wing feathers for fingers after all.
  • Fiery Redhead: Downplayed. Margaret is a red robin and can be short tempered, but most of the time, it's justified and she's usually mellow.
  • First Love: To Mordecai before he moves on to C.J. But by the series finale, he has gotten with neither one, marrying a bat woman, named Stef.
  • Funny Animal: She's a bird that wears clothes after all.
  • Gender Equals Breed: Her mother is a robin, like herself and her father is a human.
  • Graceful Ladies Like Purple: She occasionally wears purple dresses. She wore a short sleeved dress in "The Longest Weekend" when she went to the movies with her friends. In "Family BBQ" she wore fancy sleeveless dress, during the BBQ, when she introduced Mordecai to her folks. And another in "Steak Me Amadeus", she wore a strapless dress with matching high heels. She did however wore a casual purple skirt, with her shirt and pants, at the end of "Carter and Briggs" and in "Picking with Margaret".
  • Human Mom, Non-Human Dad: Inverted. Her mother is a robin like her, but her father is a human.
  • Interspecies Romance:
    • Three of her boyfriends so far have been humans (one of which was apparently a giant), and she almost went on a date with Rigby in an alternate timeline.
    • Averted with Mordecai, as they are both birds.
  • I Want My Beloved to Be Happy : In "Merry Christmas Mordecai", and "Sad Sax", she accepted that Mordecai was seeing somebody else and wants to still be friends with him.
  • Lethal Chef: In "Pie Contest", she made a pie that not only looked disgusting but it was burned and raw at the same time and it tasted like barf.
  • Limited Wardrobe: Exceptions version. Outside of her job at the Coffee Shop, she and Eileen have a good set of wardrobes. She seems to prefer wearing yellow, blue, teal and occasionally purple.
  • Masculine Lines, Feminine Curves: Downplayed with Mordecai. They are both drawn almost the same way, but the feather patterns on their respective faces play this trope straight — Mordecai's are more sharp while Margaret's is more rounded.
  • Ms. Fanservice: She tends to dress rather provocatively. In "Slam Dunk" we get a close up of her butt, seriously.
  • My Girl Is a Slut: Played straight. Margaret is shown hooking up with a new person every day. Inverted in the second season: she's seen casually hanging out with Mordecai and Rigby.
    • And then finally averted as of "Picking up Margaret".
  • My God, What Have I Done?: In "Merry Christmas Mordecai", she accidentally kisses Mordecai when he's already with CJ, and she seem to have feel ashamed when CJ saw the scene.
  • Nice Girl: She's really friendly most of the time.
  • Nightmare Fetishist:
    • In the second "Terror Tales From The Park" Halloween special, she thinks her story about a party bus that ages its riders into dust is 'funny', even though it wasn't.
    • The reason she told it in the first place was because she thought it would cheer up a terrified Pops. Obviously It didn't work.
  • Non-Mammal Mammaries: "Lady pecs", in Mordecai's words. She even gets to show a little sideboob in the concert episode, and cleavage in others.
  • Official Couple: With Mordecai as of "Meteor Moves", but the relationship didn't last too long, once she got accepted into college and it's been declared dead in "1000th Chopper Flight Party" when she tells C.J. and Mordecai that she has a new boyfriend (which turns out to be false as seen in "Not Great Double Date"). By "Just Friends', both he and Margaret decide they work Better as Friends.
  • Pink Girl, Blue Boy: The Pink Girl to Mordecai's Blue Boy. Technically, she's bright red, but it looks pink due to color saturation from digital ink and paint.
  • Pink Means Feminine: She doesn't wear pink much, but in "Pie Contest" she wore a pink apron and in Family BBQ, in her picture with her father, she wore a pink high school prom dress, and as a child, wore a pink-purple short sleeved dress, in the episode, she even had a pink-purple top with her dress. This may have been to represent her 'Daddy's girl' theme. She also has a pink sweater in "Laundry Woes"..but we never see her wore it.
  • Put on a Bus: In the season 4 finale, after she was accepted in her dream college. Came back in season 6 which added some tension for Mordecai's relationship to C.J. Ultimately, despite some lingering interest with Mordecai, she doesn't pursue it. Her relevance is quickly dropped after that and the last seen of her is at the beginning of season 8 reporting on the Park Dome's ascension into space.
  • Red Is Heroic: Margaret has red feathers and is one of the nicest characters in the series. And whenever there's action involved, she's always on the side of good.
  • Relationship Upgrade: Becomes a couple with Mordecai after sharing a kiss in "Meteor Moves", but break-up after Margaret gets into her dream school and decide to just be friends from the on.
  • Satellite Love Interest: In the entire first season not much is known about Margaret, except she's nice and has a good set of lady pecs. Justified in that Mordecai himself can't seem to get past his shyness and learn more about her besides how attracted he is to her. (Note that he's always completely surprised about her boyfriends and entertainment preferences.) She's developed a bit more beyond the first season, however.
  • Seashell Bra: During Mordecai's dream sequence in the episode "Meat Your Maker", he envisions Margaret wearing one that just ''barely'' covers her lady pecs.
  • Shipper on Deck: She encourages Eileen's crush on Rigby.
  • Skirt over Slacks: At the end of "Carter and Briggs" and in "Picking Up Margaret", she wore a purple skirt with a teal long sleeved shirt and blue pants.
  • The Smurfette Principle: In the entire first season, she was in only four episodes (one of which was only via dream sequence) and had less than three minutes' screen time combined. However, she's gotten a lot more screen time in season 2.
  • Strong Family Resemblance: When her mother is first shown, she looks exactly like Margaret with slightly more unsettled feathers and wrinkles.
  • Toothy Bird: Like Mordecai, she has teeth in her beak.
  • Town Girls: The giggly, somewhat demure Femme to CJ's aggressive, competitive Butch and Eileen's bookish, nerdy Neither.
  • True Blue Femininity: A lot of jeans and pants she wears are blue. She even wore a blue skirt in "Ace Balthazar Lives". In "Eileen Flat Screen", she wore a blue News suit, though that was to do her job. In "Merry Christmas Mordecai", she wore a blue sweater with matching shoes.
  • Tsundere: Her interest in Mordecai tends to fluctuate until mid-Season 4.
  • Uncanny Family Resemblance: Margaret's numerous aunts, uncles, cousins, and grandparents all bare a strong resemblance to her.
  • What Does She See in Him?: All of the men she seems to date are obnoxious jerks, who seem to irritate her. Except for Rigby in "It's Time", whom she really seemed to hit it off with.
    Margaret: Ugh, what boyfriend? I'm not seeing anyone right now. Guys are jerks.
    Mordecai: Gah, I know, right? Guys are the worst! (Flashes Rigby a silent "OOOOOOOOH!")
    • This extends even to Mordecai, because even though he's a Nice Guy, he is also an admitted slacker who doesn't seem at all interested in improving his life and has stated that he doesn't see himself working anywhere except the park, where as Margaret at least has her priorities concerning her future in order.

    Eileen Roberts 

Voiced by: Minty Lewis

Debuted in: Season 2, "Brain Eraser"

An adorably sweet mole girl who works at the coffee shop with Margaret. Has a crush on Rigby.

  • Action Survivor: Proves herself to be one of these in "Camping Can Be Cool". Without her, Mordecai, Margaret and Rigby would probably not have made it out of those woods alive...
  • Ascended Extra: Went from Margaret's best friend to one of Mordecai and Rigby's closest companions before officially joining the main cast in the eighth season.
  • Author Avatar: Eileen is basically Minty Lewis in mole form. Her biggest roles are generally in episodes Minty Lewis (who's a writer on the show) co-wrote with Kat Morris.
  • Babies Ever After: She and Rigby have three children (2 daughters and 1 son) in the series finale.
  • Badass Bookworm: She's a studious, academically overachieving Brainy Brunette who's also surprisingly strong and has saved (or helped to save) the day on several occasions.

  • Berserk Button: In "Dumptown, USA," she has one regarding Ethiopian food she wants to try.
  • Blind Without 'Em: After hearing that Rigby thinks she's hot without her glasses on, she tries to serve coffee without them and bumps into a table.
  • Brainy Brunette: Including straight A's in school.
  • Characterization Marches On: Her Cloudcuckoolander tendencies are played up far more in "Do Me a Solid" than they are in later episodes.
  • Cloudcuckoolander:
    • "Do Me A Solid" proved this is indeed the case.
    • And in "Camping Can Be Cool" she admits to going through a phase where she got lost in the woods a lot the previous year, as well as playing with several snakes.
  • A Day in the Limelight: "One-Pull Up" marks her first important role in an episode, without her playing second fiddle to Margaret. She gets a lesser one in "Tants" her first major role following Margaret's departure. She gets her first full example of this in "Video 101".
  • Does Not Like Shoes: Most of the time, Eileen is seen barefoot.
  • Dude Magnet: Besides Rigby, three of his classmates in "The Eileen Plan" all agreed she was a "mega babe".
  • Flower in Her Hair: Wears a mistletoe in her hair in "Merry Christmas Mordecai".
  • Graceful Ladies Like Purple: She wore a purple sweater in "TGI Tuesdays", which she shows, she can be a graceful dancer. She also wore it in "Meteor Moves", "Play Date" and "Real Date". Though in "Tants", it looked more pink.
  • Happily Married: In the finale A shot shows she's married Rigby and they have several kids together.
  • Heterosexual Life-Partners: With Margaret and to a lesser extent with CJ. Becomes a plot point in "I See Turtles" when Eileen bemoans the fact she can't hang out with both at the same time due to the lingering awkwardness over Mordecai and Margaret's kiss at the Christmas Party. Tenuously resolved with CJ calling Margaret to save Eileen, Rigby and some baby turtles, with the two agreeing to hang out though still clearly not being comfortable around one another.
  • Hidden Depths: Proves to be an adept trainer in "One Pull Up".
  • Interspecies Romance: She (a mole) and Rigby (a raccoon).
  • Jerkass Ball: In "Dumptown, USA," when she turns her fake break-up with Rigby into a real one, when it was initially to get Rigby to Dumptown to rescue Mordecai, all because she started to think negatively of Rigby and continues to carry this grudge towards him off-screen up to the end of the episode, all because of Rigby not wanting to go to the Ethiopian restaurant with her. They reconcile off-screen before the next episode, though.
  • Limited Wardrobe: Exceptions version. Outside of her job at the Coffee Shop, she and Margaret have a good set of wardrobes. She seems to like pink and blue the the most.
  • Meganekko: An anthropomorphic one.
  • Morality Pet: Eileen is more or less the one person Rigby won't be a Jerkass towards.
  • Nerd: Unapologetically so complete with Nerd Glasses. In "Meteor Moves", she mentions being a member of an astronomy club.
  • Nerds Are Sexy: She's an archetypal Nerd whom Rigby thinks is hot, and apparently he isn't the only one; she's referred to as a "mega babe" by some high school jocks in "The Eileen Plan".
  • Nice Girl: Rivals Pops for the position of the nicest character on the show.
  • Official Couple: In the episode "Dumped at the Altar" Rigby reveals that he and Eileen have been dating in secret for a couple months. According to Rigby, it was her idea since she wanted to avoid "shoving their happiness down Mordecai's throat."
  • Older Than They Look: Her very short stature and childlike side ponytail suggest that she's younger than she is, but she's the same age as Mordecai and Rigby.
  • One-Book Author: This is (currently) the only voice acting role for Minty Lewis, whose only other contribution to the show has been storyboarding a few episodes in Season 2.
  • Pink Means Feminine: Like how Margaret seems to like wearing yellow and teal tops, Eileen seems to like wearing a lot of pink tops. In "Terror Tales of the Park III", she wore a pink skirt, to go along with her 50s outfit costume. She also wears a pink dress to Muscle Man and Starla's wedding.
  • Satellite Character: Suffered from the same affliction as High Five Ghost, serving mostly as a side dish that came along with Margaret until the fifth season had her hanging out with Mordecai and Rigby proper more often. Eventually elevated to main character status in the eight season, as a result of joining the Space Park Rangers along with the others.
  • She Cleans Up Nicely: In "Access Denied". She wore a black dress, and did her hair.
  • Sherlock Scan: In "Crazy Fake Plan", she does this to try and figure out where Rigby is taking her, complete with computer screen vision.
  • Shipper on Deck: She's very supportive of Mordecai and CJ's relationship, so much so that she and Rigby encourage them to go on a real date and she helps CJ out on said date.
  • Stalker with a Crush: Eileen to Rigby. First noted in "Do Me A Solid", when Mordecai notices that Eileen is staring at Rigby from the other side of the Coffee Shop.
    • Subverted in "Diary", Margaret forgot to tell Mordecai and Rigby that she asked Eileen to water her plants since she had the guest room for the weekend. The night before Margaret revealed this, Rigby confessed that his biggest secret was that he thinks Eileen is hot without her glasses on. Guess who comes to serve their coffee without her glasses?
      • This was subverted in the fact that Eileen heard Rigby say this while she was (unknowingly to Rigby) in the guest room.
  • Stronger Than They Look: She's petite and usually very meek, but she reveals in "One Pull Up" that she was on the pep squad at her high school and can do pull-ups with ease. She also puts Rigby through some serious training to also be able to do a pull-up.
  • Sympathy for the Devil: She genuinely sympathizes with Death Bear when he’s sent to an animal sanctuary despite him trying to kill her and her friends hours prior.
  • Town Girls: The bookish, nerdy Neither to CJ's aggressive, competitive Butch and Margaret's giggly, somewhat demure Femme.
  • True Blue Femininity: A lot of bottom wear she wears, are blue. She did wore a blue sleeveless top in "One Pull Up" and briefly in "Real Date". And also a short sleeve shirt in "Lift With Your Back".
  • What Does She See in Him?: With the way Rigby acts towards her, you'd think she'd try someone else...
    • This is subverted in later episodes, with Rigby treating her nicely and even showing hints of being attracted to her. They eventually become an Official Couple, with Rigby actively working to better himself for her (and himself).
  • Zettai Ryouiki: In "Bald Spot", she wore white stockings that were either B Over-Knee or A Thigh-High.

    Cloudy Jay "CJ" 

Voiced by: Linda Cardellini

Debuted in: Season 3, "Yes Dude Yes"

A cloud girl who Mordecai goes on a blind date with after thinking Margaret was engaged and befriends as a result.

  • Action Girl:
    • In "Dodge This". Despite her team being rookies, they make it all the way to the finals of the dodgeball tournament and end up winning the whole thing. She even beats Mordecai, the park's best player, one on one after they work things out.
    • She even saved him and Rigby, with Eileen's help, in "Portable Toilet".
  • Amicable Exes: Averted with Mordecai. While they ended their relationship on amicable terms, even hugging one another, CJ is (understandably) a little frosty to Mordecai and the creators confirmed they no longer speak with each other post-breakup.
  • Ascended Extra: Started out as a one shot character, later returns as a recurring cast member... only to come full circle and be Demoted to Extra.
  • Big Damn Kiss:
    • With Mordecai in "New Years Kiss", albeit unknowingly as she couldn't tell it was him until they dropped their disguises.
    • Done again at the end of "Real Date", except this time, they're a couple.
  • Betty and Veronica: The tomboyish, hot-headed "Veronica" to Margaret's girlish, calm "Betty" for Mordecai's "Archie". At first, Mordecai is with Margaret but they break up because she got into her dream school and he eventually starts a relationship with CJ. Although, due to Mordecai mixed signals which included him kissing Margaret despite being in a relationship with CJ has led to her getting hurt over and over again. Finally, when he attempts to make a Love Confession to CJ or Margaret at Muscle Man and Starla's wedding, they both decide to break up. And in regards to Margaret, both amicably agree they are Better as Friends.
  • Beware the Nice Ones: Went berserk when Mordecai chose Margaret over her but only because she thought Mordecai and her were dating.
  • Biker Babe: She revealed that she has a motorcycle license and she did motocross when she was younger.
  • Birds of a Feather: With Mordecai. They both like rock bands, playing video games, goofing off, etc.
  • Bizarre Alien Biology: She can turn into a living storm.
  • Boots of Toughness: She's tough, spunky, competitive, and she wears black boots with her regular attire.
  • Character Development: Subtle, but CJ does get a better hold of her temper. In "Yes Dude Yes", she becomes completely furious at Mordecai for perceiving him accidentally asking out Margaret as a sign of him playing with her feelings. She does it again in "The 1000th Chopper Party", but is ashamed of how she almost killed Margaret's parents as a result of thinking Mordecai and Margaret were together. And when she learns that Margaret does still have feelings for Mordecai, she gets angry and stays so, but she manages to calm herself down enough to avoid doing any damage.
  • A Day in the Limelight: She gets her own episode in "Daddy Issues".
  • Demoted to Extra: After she breaks up with the Mordecai the show pretty much forgets about her save for a cameo here and there.
  • Embarrassing Last Name: Subverted in "Daddy Issues" when she revealed that her father is Carl Putter, a mini-golf champion. Rigby asked if her last name is "Putter" but she tells him that's her father's mini-golf name.
  • Fatal Flaw: CJ has two:
    • Jealousy. Her problems with Margaret come from the fact that she honestly doesn't trust her around Mordecai and thinks that he still has feelings for her. She is pretty bad at keeping a clear head when she sees the two of them together and ultimately leads to her nearly getting them killed because of a genuinely innocent incident.
    • Hair-Trigger Temper. CJ has a really bad habit of allowing her temper to get the best of her and jumping to conclusions instead of thinking things out rationally. Coupled with her aforementioned jealousy issues, this leads to a danger combo. In her final major appearance in the series, she preemptively breaks things off with Mordecai because she assumed that he would choose Margaret over her.
  • Foil To Margaret. Both are Mordecai's main love interests who he later gets into a complicated Love Triangle with. Margaret was Mordecai's girlfriend with both being the same species, a girly girl and Daddy's Girl, and Mordecai didn't have the nerve to ask her out because of his own fears; CJ is Mordecai's second girlfriend but they're both different species, she has a rocky relationship with her father, and Mordecai was reluctant to start a romance with her because he was somewhat hoping Margaret would come back. For their breakups and being Just Friends — Mordecai always hoped to date Margaret and they did, but changing priorities (i.e., Margaret's college acceptance) had them break up but agree to a friendship; Mordecai tried to be friends with CJ but realized his feelings for her after "I Like You, Hi", and then they stared dating but break-up because of the confusing Love Triangle and Mordecai being a Master of the Mixed Message. The creators confirmed that while Mordecai and Margaret are still friends after the 25 year timeskip, he and CJ aren't.
  • Gamer Chick: Just like Mordecai, she's pretty good at playing video games. She even managed to make the top high score three times on the same arcade game.
  • Goth: In "Real Date", there's a picture of her in her Couple Corral profile (a dating site) when she was going through a Goth phase.
  • Heterosexual Life-Partners: Takes Margaret's place as Eileen's until Margaret returns to town.
  • High-Pressure Emotion: Because she's a cloud, when she gets angry or upset she turns grey.
  • Hulking Out: She turns into a giant stormy cloud (shaped like an actual cloud rather than her human-like shape) and causes an actual storm when she's upset at Mordecai.
  • Insecure Love Interest: A large part of the reason why her and Mordecai have relationship troubles is that despite Mordecai constantly trying to prove his dedication to her she is afraid that he still has feelings for Margaret and when seeing the two together she tends to jump to conclusions. Comes to a head in "1000th Chopper Flight Party" when she sees the two of them together because of circumstances she wasn't aware of. She instantly flies off the handle and goes storm cloud on them, nearly killing Margaret's parents.
  • Interspecies Romance: She (a cloud humanoid) and Mordecai (a blue jay).
  • Irrational Hatred: By late Season 6 and early Season 7, she starts to develop this of Margaret, due to her jealousy of her and Mordecai, to a point when she caught a glimpse of Margaret on television in "Local News Legend," she quickly changes the channel out of spite.
  • Just Friends: In "Dodge This", Mordecai and CJ both agreed to start over as friends. "Portable Toilet" makes it rather obvious they have feelings for each other. Eventually blown to all hell in "I Like You Hi".
  • Limited Wardrobe: While Margaret and Eileen have their own set of wardrobes, CJ always wear a stripe sleeveless shirt, brown shorts and black boots. She dose wear other outfits, but they were for occasions or when they were convenient for the plot. In "Sad Sax", due to winter, she did wear a blue jacket...with shorts. And later in the episode, she did wear warm pants and different shoes...with her sleeveless stripe shirt.
  • Love Hurts: Mordecai honestly hurts her by choosing Margaret over her.
  • Love Interest: CJ becomes Mordecai's second love interest after his break up with Margaret.
  • Manic Pixie Dream Girl: Downplayed. She brings Mordecai out of a funk after he thinks Margaret is engaged, but doesn't really change him in any way. Played straight in "I Like You Hi", she both helps him move on from Margaret for good and gets him out of his habit of never making a move.
  • My God, What Have I Done?: When she attacks Margaret's father's chopper, thinking Mordecai has betrayed her again, she nearly kills Margaret's parents and doesn't realize it until Margaret tells C.J. that she's not getting back together with Mordecai because she already has a boyfriend and they really are Just Friends. The episode ends with C.J. crying and running off over her destructive antics.
  • Nice Girl: When she first meets Mordecai, she understands that he's not interested in dating at the moment so she hangs out with him to cheer him up. Reinforced when it turns out she was avoiding Mordecai not because she was mad at him for kissing her but because she thought HE was mad at her for running out on him.
    • Also in "Sad Sax", when she was angry with Mordecai about the whole kissing Margaret thing, she didn't take it out on Eileen and Rigby, and still hang out with them.
  • Not So Above It All: While normally a Nice Girl she is typically very frosty towards Margaret because of the kiss she shared with Mordecai. While she has forgiven Mordecai for this she seems to see it as evidence that she can't trust Margaret to be around him and as such doesn't want to be around her.
  • Obliquely Obfuscated Occupation: We don't know exactly what her job is. In "I Like You Hi", she said that she can watch TV at her job and nothing more came of it. In the Season 7 finale, she is seen working as a tour guide for children, but it's unknown if that's her actual job or if she was just volunteering.
  • Only Known by Initials: Her name is actually Cloudy Jay. Or Cloudy Jane . . .
  • Paper-Thin Disguise: Apparently neither Mordecai nor Rigby could tell it was her at the New Year's party despite just having simple mask over her eyes. Then again neither could she since Mordecai was wearing the same thing.
  • Pink Means Feminine: She's tomboyish, but in "Real Date", she did choose to wear a pink sweater to go with her dress. In "Daddy Issues", she wore a pink sleeve shirt with her overalls when she was younger and she also wore a pink skirt for the mini golf. These three examples go with Tomboy with a Girly Streak.
  • Put on a Bus: Introduced in Season 3 but seems to disappear without a trace, generally believed that she was just a one shot character. That is until Season 5. But then she makes her swan song in "Dumped at the Altar" (excluding her cameo in Season 7). By Season 8, CJ is all, but forgotten.
  • Red Eyes, Take Warning: Her eyes start growing red when she transforms into a storm in "Real Date".
  • Relationship Upgrade: Agrees to go out with Mordecai in "I Like You Hi". But their relationship officially ends in "Dumped at the Altar.
  • Romantic False Lead: To Margaret, though to the show's credit, while it was obvious that Margaret really hadn't gotten engaged, she was set up. Subverted now that Margaret's gone.
  • Second Love: To Mordecai.
  • Shapeshifting Excludes Clothing: When she goes storm cloud she leaves her clothes on the ground and goes back into them when she calms down.
  • She Cleans Up Nicely: In "Real Date", she wore a red dress with matching flats and a pink sweater.
  • Single Woman Seeks Good Man: She considers Mordecai a nice guy and gets upset with him when she believes he's acting like a jerk.
  • Tank-Top Tomboy: Along with her boots and short shorts, her main attire is her striped tank-top to match her tomboyish personality. In one episode, she's shown to be wearing a teal one while jogging.
  • Tomboyish Name: Her name is Cloudy Jay (or Cloudy Jane), but she goes by CJ.
  • Tomboyish Ponytail: She has a fluffy cloud ponytail.
  • Took a Level in Jerkass: In "Dumped at the Altar," just after Mordecai makes a speech and is about to express his feelings towards CJ, CJ does not give Mordecai a chance and dumps him on the spot, expecting the worse that he could be talking about Margaret. In addition, she starts to develop an Irrational Hatred of Margaret. This is justified as she felt her heart getting broken.
  • Town Girls: The aggressive, competitive Butch to Margaret's giggly, somewhat demure Femme and Eileen's bookish, nerdy Neither.
  • Violently Protective Girlfriend: In "Real Date", the C.E.O. of Couple Corral learned too late why you should never hurt Mordecai.
  • Walking Spoiler: Her relationship with Mordecai, since it directly spoils Margaret's exit.
  • "Well Done, Daughter!" Girl: CJ never got any respect from her dad, especially when it's involving mini-golf. The two of them make peace after CJ finally beats him.
  • What Happened to the Mouse?: Last seen in "Rigby's Graduation Special" coming to the park to celebrate Rigby's graduation and looking on horrified when the Park Dome blasts off into space with the park crew (and Eileen) in it. She never makes an appearance after that. Even in the finale the dome returns back to Earth and many of the crew's families come to greet them. The most we get is a painting that Mordecai makes of her in the ending montage. According to the creators, CJ went on to become a professional dodgeball player and doesn't keep in contact with Mordecai, Rigby, Eileen, or Margaret.
  • Who Wears Short Shorts?: CJ wears brown shorts.
  • You Wouldn't Like Me When I'm Angry: Get her miffed enough and she'll turned into a real storm cloud that can reek some serious havoc.

  • Lookalike Lovers: She and Muscle Man look almost exactly alike despite not being blood related.
  • Morality Pet: She is the one that Muscle Man is the least jerkass towards. In fact, he is consistently kind and loving whenever he is near her.
  • Not Good with Rejection: And by "Not good", we mean she goes on a town destroying rampage when Mordecai dumps her.
  • Official Couple: With Muscle Man, and the two are engaged and married by the season 6 finale.
  • Person of Mass Destruction: You think Muscle Man tears stuff up when he's mad? She outdoes even him.
  • Progressively Prettier: In her first appearance, she's ill-mannered and quite ugly. As she made more appearances, it was toned down and now she's much cuter.
  • She Cleans Up Nicely: She's still no looker, but cleans up nice during "Fancy Restaurant".
  • Stout Strength: The same as her boyfriend/husband — Starla is fat but has a lot of strength.
  • Strong Family Resemblance: When her parents make their debut episode, it's shown that Starla gets her looks from her father.
  • Super Strength: She's not known as "Muscle Woman" for nothing.
  • Token Minority Couple: Coincidence or not, she and her parents are the only stout, green-skinned people around besides Muscle Man and his relatives.

    Mr. Maellard 

Voiced by: David Ogden Stiers

Debuted in: Season 2, "Dizzy"

The owner of the park and the father of Pops.

  • Accidental Misnaming: He keeps getting Benson's name wrong by calling him Beancan, Bert, Beanbag, Ball Bucket, Beanton, Bean Teen, and Beanson. By the end of "Benson Be Gone", he finally gets Benson's name correct, which sticks for future apperances.
  • Ambiguously Evil: He's shown developing very suspicious plans for the Park throughout the seventh season that ultimately send the whole thing into space. In the Finale Season, we discover he was Good All Along: he was preparing them to save the universe from Anti-Pops.
  • Conspicuous Consumption: When he makes a mess of his limousine's upholstery he just buys a whole new limousine rather than have it cleaned.
  • Cool Car: He is driven around in a white limousine called "The White Stallion" that's equipped with machine guns, tire spikes, mini missiles, wheel spikes, grapple guns, lasers, and a massive missile.
  • Distinguished Gentleman's Pipe: Seen with one on occasion
  • Hypocrite: He hates paying for damages that happens in the park caused by Mordecai and Rigby, but when he damages or ruins his own stuff he doesn't care because he's rich and he can always replace it.
  • Jerkass: He treats everyone who isn't Pops like crap. Even when he does something good in sending the crew into space to fight Anti-Pops, he tells none of them ahead of time.
  • Jerkass Has a Point: In "Lunch Club" he cuts off Benson blaming Rigby for a screwup to put some of the responsibility on Benson himself, as he sees Rigby's incompetence as a result of Benson's methods. He's right on the points that A) Benson's methods are not effective at getting the workers to do their jobs right (his constant yelling and Mordecai and Rigby just makes the two dismissive past a certain point), and B) Benson forced Rigby into working heavy machinery while he was sleepy (Rigby's own fault in this case but Benson did have some warning about it ahead of time).
  • Jerk with a Heart of Gold: He does care for his son, Pops, even if he isn't too fond of the other staff.
  • Like Father, Like Son: He may be a grump but he's just as scatterbrained as his son and this was before he revealed he adopted Pops.
  • Lonely at the Top: Mentions this in one episode when he thinks that his birthday was forgotten.
  • Killed Offscreen: He dies in between the crew's return to Earth and the 25 year reunion in the last scene.
  • Mean Boss: He is way meaner than Benson. And any problems that occur in the park, thanks to Mordecai and Rigby, he takes his frustration out on Benson.
  • Miniature Senior Citizens: He may be a short, elderly man but he's still taller than Rigby.
  • Outliving One's Offspring: Mr. Maellard dies many years after his adopted son Pops sacrificed himself to save the universe. In the show's epilogue he's shown quietly grieving during the celebration of the park staff's return.
  • Perpetual Frowner: In most appearances, though he can crack a smile.
  • Pet the Dog:
    • In his debut, he would mispronounce Benson's name and barely thanks him. But when Benson help saves the park in "Benson Be Gone", he thanks Benson properly and finally gets his name correct.
    • A minor one from "Dizzy," when he congratulates Pops on giving a speech.
    • His tape he made for Pops in "The Ice Tape" He explains he raised Pops as his own after finding him in a crater, trying to raise him normally and, when it was clear Pops couldn't escape his destiny to battle Anti-Pops, did everything he could to prepare Pops for it by sending him into space, with the park crew along to help him.
  • Rockers Smash Guitars: He owns a guitar, autographed by a famous rock star, just for this purpose. Mordecai, Rigby, and Benson were left speechless after going through all that trouble to replace the guitar Benson accidentally broke.
  • "Shaggy Dog" Story: It's pretty much a waste of time trying to replace or fix something owned by him because he'll ruin it, accidentally or purposely, and not care about it because he's rich.
  • So Proud of You: In a video tape to Pops explaining Pop's origins, he tells him that's he's always been proud of what he's become. Considering this is the last time Pops will hear from him, that's saying something.
  • Visual Pun: He's a sour lollipop.

Chad and Jeremy are fully clothed, take their work seriously, received degrees from The Institute of Technical Technology and appear to always agree with each other.
  • Hero Antagonist: They're technically the antagonists as Mordecai and Rigby are trying to get them both to not finish their jobs, while Chad and Jeremy are trying to finish their work.

    Quintin "Quips" Quippenger 

Voiced by: Matt Price

Debuted in: Season 4, "Quips"

A yeti who is Skips' cousin who constantly tells terrible jokes and gets on the nerves of everybody.

  • Comically Missing the Point: He is fully unaware that everybody hates his jokes and thinks the only reason why people don't laugh is because they don't get his jokes. This is the reason why he got fired from the comedy club. He finally figures it out once Skips finally tells him the truth.
  • Creator Cameo: His voice actor is one of the writers of the series.
  • Don't Explain the Joke: He explains a lot of jokes if the person/people he's telling them to don't laugh (but that's because they aren't funny).
  • Foil:
    • To Don. Both are family members of one of the Park's employees who contributed to an episode's plot and are both nice guys. Don was liked by all of the Park members except from his older brother, Rigby, who tried to drive Don away; Quips is considered the In-Universe scrappy by all of the Park members except by his cousin, Skips, who is the only one who wants Quips around.
    • To Skips. Both are friendly, albino yetis with similar sounding names and their main romance was with a human. Skips has a muscular body, is fairly serious, lost the love of his life, and is well-liked by the other Park employees; Quips has a slimmer build, loves to make jokes, is happily engaged to his fiancée (who he is presumed to have later married), and is barely tolerated by his cousin's friends.
  • Friendless Background: Despite having a fiancée, he has absolutely no friends for obvious reasons. He made Skips his best man for his upcoming wedding and has a bachelor party with just Skips, Mordecai, Rigby, Muscle Man, and Hi-Five Ghost because of this particular reason.
    Quips: (asking a request from Skips) At the end of the night, I want to eat wings on a hill with my best buds! Well, your best buds. Can I borrow your best buds? Just to reiterate, I don't have any friends.
  • Incredibly Lame Pun: He does almost nothing but make awful puns and jokes.
  • Innocently Insensitive: Quips is for sure a nice guy and means well...but his jokes are not only unfunny, they also typically are made at the expense of whomever he is telling it to, whether it be making fun of Pops’ head, Benson’s lack of hair, or straight up calling Reginald a baby (which while technically true on an appearance level is also very incorrect on a whole other bunch of levels) and insisting otherwise as well as consistently making fun of his drawings. But again, he isn’t aware of how his jokes are viewed by anyone he tells them too and thus is unaware of how he comes across in general, until Skips finally tells him.
  • Interspecies Romance: Quips is a yeti and his fiancée is a human.
  • Keet: He's almost always upbeat.
  • Laughing at Your Own Jokes: He constantly tells bad jokes that only he finds funny.
  • Meaningful Name: He thought people called him "Quips" because his last name is Quippenger, but it's actually because he constantly tells really bad jokes.
  • Nice Guy: Annoying nature aside, Quips is genuinely sweet-natured.
  • The Scrappy: In-universe and out. His constant bad jokes and not shutting up about them is why everybody hates him. Even Pops, who can tolerate most people and is a bit of an oddity himself, doesn't want to be associated with him. Although this was most likely deliberate. He appears to have dropped this as of his second appearance on the show.
  • Too Dumb to Fool: When Skips and Quips are trapped inside a mirror box, Reginald, one of the Guardians of Eternal Youth, tries to make Quips understand how unfunny he is by making reflections of Quips appear inside the box telling his bad jokes. It doesn't work because he finds the jokes hilarious.
  • Too Dumb to Live: He constantly makes fun of Reginald and doesn't take the game they are playing seriously which angers Reginald into trapping him and Skips inside a mirror box. He thinks he can get them out by telling Reginald more jokes which makes the situation they are in even worse.
  • Uncanny Family Resemblance: His resemblance to Skips is amazing, with the only difference being in hairstyle and body type.
  • Verbal Tic: "Zingo!"

Voiced by: Sam Marin

Debuted in: Season 4,"That's My Television"
Hope you saved room for dessert!

A talking robotic TV set and the star of the popular 80s sitcom, That's My Television. He actually wants to break free of stardom and seeks Mordecai and Rigby's help.

  • And I Must Scream: He's been trapped in a mobile TV box for years and can only survive with a steady supply of air from the 80s. Judging by the timespan, he's been in that box since he was a teenager.
  • Catch Phrase: Two cheesy sitcom ones: "I hope you saved room for desert!" and "Hey, It's my turn to Drive!"
  • Celebrity Is Overrated: Oh lord, like you'd never believe. RGB 2's career was a miserable life of virtual slavery, confined to a small prison and forced to keep the act going to appease greedy TV executives and obsessive fans.
  • Cool Old Guy: Well, he's been around since the 80s and he's a very old, decrepit man inside that Tv. Nonetheless he's a cheerful and friendly fellow.

  • The Dog Bites Back: He finally gets a chance to fight back against his captors with Mordecai and Rigby's help.
  • I Just Want to Be Free: All he wants is to be free of his hellish life as an actor, and to see the Pine Mountains with his real eyes.
  • Man in the Machine: He's actually a weak, elderly man operating a small robotic box that keeps him alive with "air from the 80s".
  • Nice Guy: For how depressing his life is, RGB 2 is kind and grateful to the two for freeing him.
  • Phlebotinum Dependance: He can only survive on canned air taken from the 80s. This is likely because his lungs wouldn't be used to new era air and can only sustain air from his home time period.
  • TV Head Robot: He's a talking TV set with tubular arms and a digital face.Or so it seems.
  • Unrobotic Reveal: The talking TV turns out to be a suit operated by the real RGB 2 -an aged human actor imprisoned for years.
  • Walking Spoiler:Or rather rolling, since it's unlikely he can walk after years in that box.

An artist and Mordecai's future wife.

  • All There in the Manual: Her name was revealed from the creators on an AMA reddit page.
  • Babies Ever After: Had two sons and one daughter with Mordecai.
  • Clingy Jealous Girl: Slightly in the "25 Years Later" comic, but justified as Mordecai and she are married and seeing him aged down back to his 20s (Long story) and hanging with a likewise de-aged Margret didn't help matters.

Space Tree Station

    Commander Rawls 

Voiced by: D.C. Douglas

Debuted in: Season 8, Episode 3

The Commander of Space Tree Station, where the Park Crew ends up after being blasted into space.

  • Ambiguously Evil: Keeps the true purpose of the SPARK initiative from the crew and dodges Benson's questions when confronted. Subverted as of "Space Escape": He only doesn't explain why Pops is important because there isn't time, and does everything in his power to protect the park crew. It's also made clear whatever the Park's mysterious mission is, it's a good one.
  • Big Good: Of In Space For the first third anyway.
  • Drill Sergeant Nasty: A mild example, as he only puts on the persona to try and get Benson not to quit, and the worst he does most of the time is tell his crew to drop and give him 20.
  • A Father to His Men: Willing to lay down his lives for his men in a heartbeat. Also see Reasonable Authority Figure Bellow.
  • Heroic Sacrifice: Twice! First he stalls long enough for the Park Crew to escape, though they use the opprotunity to help save the rest of the Space Tree instead, and then he holds the door for them and stays behind to keep it up.
  • Jerkass Has a Point: While he screwed up trying to push Benson using a Drill Sergeant Nasty persona, he points out that their combat training does have a purpose, as not every alien they encounter will be friendly, as proven by their encounter with the Reaperbots.
  • Nice Job Breaking It, Hero!: Nearly causes Benson to leave trying to do reverse psychology.
  • Reasonable Authority Figure: Behind his gruff demeanor is a truly caring captain who at worst gives out pushups or a just punishment for endangering other crew members, and in the latter case offers an alternative when asked.
