The characters on ''WesternAnimation/RegularShow'' include:


!!!Voiced by: J.G. Quintel
!!!Debuted in: "Pilot"/Season 1, "The Power"
[[caption-width-right:197:"Ugh, we're so fired for this..."]]

A tall blue jay out of art school who works with his friend Rigby at the park. Between the two, Mordecai is the more mature, although he will sometimes play along with the more enthusiastic Rigby's hijinks.

* AmericanAccents: He has an obvious So Cal accent, due to California native J.G. Quintel just using his normal voice for him.
* AttentionDeficitOohShiny
* AuthorAvatar: Besides being voiced by him, Creator J.G. Quintel has stated that Mordecai is based on his own personality traits (what he'd do in any given situation).
* {{Badass}}: Taking down {{Eldritch Abomination}}s and other monsters nearly once a week definitely makes him qualify.
** BadassDriver: Usually in high speed situations he's the one behind the wheel and can pulls off some pretty gnarly tricks.
** MeaningfulName: His name is Hebrew for "warrior".
* BeardOfSorrow: After [[spoiler: Margaret leaves. He shaves it off after the rest of the park help him get back to normal again.]]
* BirdsOfAFeather: With C.J.
* BrilliantButLazy: He is much smarter than Rigby (although that's not saying much), and holds a high school diploma.
* CatchPhrase: "OOOOOOOOH!", "Dude", "Awww Sick!", and "YAY-YUH!", the last of which is pretty much Quintel's own catchphrase.
** Also whenever Rigby's in danger or Mordecai's worried about him, he sometimes stretches out his wing and cries "Rigby!"
* CantGetAwayWithNuthin: The main element of a lot of episodes is Mordecai and Rigby attempting to shirk some responsibility and usually doesn't resolve unless they own up to what they've done.
* CharacterizationMarchesOn: Yeah, he still punches Rigby in the arm once in a while when he says something jerkish or idiotic (though that seems to be fading as well), but he became less abusive towards Rigby in comparison to the earlier episodes (when's the last time you ever saw them play punchies?)
* CharacterDevelopment: He's gotten better at talking to Margaret, and they've had romantic moments together even if they're not technically dating. She's even let him kiss her. This would never have happened in the earlier episodes. He also appreciates Rigby more (only punching him when he says or something stupid or assholish instead of for no reason), and tends to care far more about him than he did early on.
** He gets some more in "I Like You Hi". [[spoiler: Asking CJ out instead of beating around the bush like he did with Margaret once he realizes he does like like her. ]]
* CheatedAngle: He's almost never shown head-on, and even when he is, his head crest is still angled.
* TheConscience
* CoolLoser
* DeadpanSnarker: Occasionally, but when he does, it's usually towards Rigby.
--> '''Rigby''': ''(when applying his mom's cleaning formula)'' "By the power of my mom, stain be gone!"
--> '''Mordecai''': "Hmm, maybe that's why your house is never clean."
* DidNotGetTheGirl: Toward the end of "Steak Me Amadeus", Margaret leaves for her dream school, believing she may never get another chance like this again. At least she's got her priorities in order.
* [[DopeSlap Dope Punch]]: Tends to occasionally punch Rigby in the arm when he either says something stupid, insensitive or insulting in later episodes.
* FeatherFingers
* TheGadfly: Picks on Rigby. A lot. Though it's toned down from physical violence for no reason to verbal jabs and the occasional physical one when Rigby either insults him or says something really stupid or insensitive in later episodes.
* GenreSavvy: In "Butt Dial", the episode begins with Mordecai raving about how their night hanging out with Margaret and Eileen went so smoothly. Specifically, that "nothing went wrong. No space portals, no video demons, nobody got hurt." Though inevitably, something weird still happens later in the episode.
* GoingCommando: The secret that Mordecai reveals in "Diary" is that "[he] likes going commando. A lot." Considering he goes around completely naked at all times, this much should already be obvious.
* HeroicBSOD: Shown in the montage at the beginning of "Laundry Woes" [[spoiler: After Margaret leaves. He snaps out of it after the entire park pulls together to help him.]]
* HeterosexualLifePartners: With Rigby. In the episode "Don", Mordecai even says that they're like brothers.
* {{Hipster}}: Several instances, but the quote "You can't touch music. But music can touch you" wraps it up.
** "You gotta be in the know to know, ya know?"
** Also the bit in "Grave Sights", where his movie of choice is a black-and-white foreign film.
*** Almost all the bands he and Rigby listen to are British Glam Metal bands, implying that they revere the British (which is common amongst American hipsters).
** The entire episode, "Cool Bikes."
** Mordecai lists the "annoying music" as one of the reasons why he doesn't like going to clubs, though Rigby comments that he likes the music.
* [[HerHeartWillGoOn His Heart Will Go On]]: It takes him a bit, but he eventually moves on from Margaret with CJ.
* HopelessSuitor: With Margaret. Hell, when he ignores her ([[ItMakesSenseInContext due to being mindless]]) in "Brain Eraser", she suddenly finds him attractive.
** Deconstructed later on in the series until it's reduced to nothing.
* InformedAbility: In "Slam Dunk", Mordecai apparently has enough knowledge in HTML coding for Margaret to ask him to help make her website.
** He also mentioned offhand in one episode that he went to an art college, though he has never actually shown any real interest or talent in art (though that could just be a throwaway reference to his creator and voice actor, J.G. Quintel), though in "The Best VHS in the World," he did tell Button [=McButtonWillow=] that he should take life drawing classes because of how bad his fanart of The Best VHS in the World is. In "Fool Me Twice", Mordecai brings up his art college again and Rigby revealed that he never graduated which may explain why he works as a groundskeeper. It becomes subverted in "Bad Portrait" where Mordecai paints a portrait and it's revealed that we never see him draw or paint is because of his fear of people misinterpreting or getting offended by his artwork. He gets over it by the end [[spoiler: Paints a painting that is incredibly well received and ends up hung in Benson's office]] and is seen taking an art class at community college with CJ in "I Like You High.
** In "Rigby in the Sky with Burrito", he used to play the saxophone in high school when he was in jazz band.
* JerkWithAHeartOfGold
* ManChild: He's a lot more level-headed and less impulsive than Rigby, but just as eager to slack off and do childish things.
* NiceJobBreakingItHero: He and Rigby are (in)directly responsible for a ''lot'' of the really weird things that happen during the show. Though, unlike Rigby, he usually knows when to play and when to be serious when things hit the fan, quickly leaping to straighten things right if it's in his power.
** Perhaps the ''biggest'' example of this so far is during the episode "It's Time" when he [[spoiler:accidentally kills Rigby and has to go back in time to save him.]]
* NotSoAboveItAll
* PettingZooPerson: WordOfGod is that he's "a dude in a bird's body". He doesn't fly or do anything remotely avian.
* PinkGirlBlueBoy: Blue Boy to Margaret's Pink Girl.
* OfficialCouple: Mordecai and Margaret eventually get together, but her having to move far away for school ended the relationship. After taking a while to get over her, Mordecai is now officially with CJ.
* RedOniBlueOni: The blue to Rigby's red.
* TheSlacker: Doesn't appear so at first, but often joins in with Rigby's escapades for the sake of rivalry or just for the hell of it. "Just Set Up The Chairs" is a prime example. Since season two had started, he seems to be more inclined to go along with Rigby, but still has a better sense of responsibility than Rigby.
* ToothyBird: He is drawn with a beak full of teeth.
* TotallyRadical: Says "dude" and "man" a lot.
* VerbalTic: He tends to say "hmm" a lot, usually with a head-bob.
** He also has a tendency to stretch out words when excited.
** Plus, he usually uses "dude" when referring to Rigby.
* VitriolicBestBuds: With Rigby. Eventually he also befriends Benson and Muscle Man, despite not getting along well at first.
* WeirdnessMagnet

!!!Voiced by: William Salyers
!!!Debuted in: "Pilot"/Season 1, "The Power"
[[caption-width-right:198:STOP TALKING!]]

A much shorter raccoon and Mordecai's best friend / frequent coworker. Being energetic and immature, he's usually the one who instigates any sort of trouble that Mordecai or the other characters get into. He is a high school drop-out who never received his diploma, and Mordecai thinks that's pretty funny.

Has a very tall younger brother named Don, who is an accountant.

* {{Adorkable}}: Not as much as Eileen but has his moments.
* AdultsDressedAsChildren: Type A in "Fuzzy Dices". When the park workers needs kid to get inside a SuckECheeses center, they have Rigby wear a hoodie, a fanny pack, and a backward cap due to his size.
* AlliterativeName: Rigby the Raccoon. Probably done for humor purposes.
* AllMenArePerverts: The only reason he didn't want to see "Pajama Sisters 2" is because "They're just gonna talk about their feelings -- ''fully clothed''," yet in "The Unicorns Have Got to Go," he didn't see the appeal of having sexy women tearing a man's clothes off as seen in the Dude Time cologne commercial.
* AntiHero: Despite being selfish, he's still often willing to do the right thing.
* AntiRoleModel: He's lazy, greedy, rude, selfish, smug and convinced he's a lot smarter than he actually is.
* AloofBigBrother: One to his brother Don. Namely because Don was taller, stronger and smarter than Rigby. They patched things up though.
* AmusingInjuries: Rigby, The One-Cheek Wonder. Illustration on the [[Radar/RegularShow Getting Crap Past the Radar subpage]].
* AttentionDeficitOohShiny
* BackToSchool: After being mocked for never getting his diploma, Rigby briefly tried going back to school. It didn't last long.
* {{Badass}}: Taking down {{Eldritch Abomination}}s nearly once a week definitely makes him qualify.
* BadLiar: Partially averted; Rigby is perfectly capable of telling a convincing lie, but Mordecai is better than him at lying.
* BigEater: Rigby is definitely one of these.
--> (''Rigby's stomach growls'')
--> '''Mordecai''': Don't touch that cake.
--> '''Rigby''': It's a medical emergency!
--> '''Mordecai''': You just ate a sandwich!
** At one point he eats so much junk food his body literally quits on him.
* BookDumb: He's a high school drop-out, and his recklessly stupid attitude only reinforces it. But there is more to him because of:
* BrilliantButLazy: More-so than Mordecai. The only reason he hasn't been fired is because he's actually efficient when properly motivated.
* ButtMonkey: Possibly one of the best examples, every episode will result in some pain coming to him or even dying in some episodes. Add in his physical weakness where he can't retaliate and near everyone can beat him up and he's almost TheChewToy.
--> '''Benson''': First on the agenda is trophy talk. Who gets the trophy on what day? I think the schedule is more than fair.
--> (''Everyone on the team is scheduled to have the trophy for two days each week, except Rigby who only has it one day.'')
* CantGetAwayWithNuthin: Along with Mordecai but Rigby mostly makes problems by trying to be cool or doing something petty that he thinks is irrelevant. Naturally, it will always come back to get him.
* CartoonyTail: Rigby's tail always points up when he's standing or walking. Real life raccoons keep their tails on the ground when standing, as their hind legs are usually too weak to support their bodies on their own.
* CatchPhrase: "OOOOOOOOH!", "Check it", and "STOP TALKING!".
** He also has 'Ah, what?' whenever Benson asks him to do anything (usually as punishment) and 'Why?' when Benson threatens to fire him.
* CharacterDevelopment:
** Rigby has grown much closer to Eileen; in "Yes Dude Yes" he eagerly suggests going to the movies with her, while in "Do Me a Solid" he only accepted a date as a solid, and did everything possible to sabotage it. Later, it goes even further in "Diary", where he admits that she looks hot without her glasses on. In "Terror Tales of the Park", his tale even has a photo of her when he's transformed into a house. Seasons four and onward have him spending time with her when Mordecai's unavaliable.
** Rigby also became [[ShipperOnDeck more supportive Mordecai's crush on Margaret.]] He started off [[FriendVersusLover hostile of that aspect]] but eventually grew to trying to help Mordecai out in that regard.
** He's also grown a better understanding of Mordecai's relationship than Mordecai himself, pointing out problems Mordecai out and trying to help him solve them.
** As seen in "Bank Shot", he now has a much better relationship with Don after working out his resentment towards him in "Don" and calls him for help when everyone else is mad at him at the moment.
* CharacterizationMarchesOn: Similar to Mordecai, Rigby has become [[TookALevelInKindness less of a jerkass/brat]] over the course of the series. He's still a massive slacker though.
* CheatedAngle: He, too, is rarely seen from the front.
** He also sometimes gets what fans refer to as the [[FanNickname "shark face"]], as seen [[ here]].
* TheChewToy: Though he brings it on himself sometimes.
* {{Claustrophobia}}: He displays this in "Terror Tales of the Park II" and in "Portable Toilet" and he doesn't think clearly when he's in closed spaces.
-->'''Rigby''': We're gonna starve before they find us! Why did you eat the whole sandwich?! You should of saved some just in case!
-->'''Mordecai''': Dude that makes no sense.
-->'''Rigby''': [[NoYou You makes no sense!]] (pounds on the door and screams) [[HypocriticalHumor Help, I'm trapped in here with a crazy person!]]
* CoolLoser
* CrouchingMoronHiddenBadass: Proven in the Death Punch episode.
* DeadpanSnarker: Not as much as Mordecai, but is able to hold his own.
-->'''Mordecai''': Come on, Margaret and I are just friends.
-->'''Rigby''': Yeah, [[GettingCrapPastTheRadar friends without benefits.]]
* DeathIsCheap: Rigby has died at least three times (expelled from his own body, thrown into a time void, crushed during an arm wrestling match), being revived each time.
* {{Determinator}}: Stayed attached to Muscle Man's chest for ''eight solid hours'' in a mentor-harness just so he could keep his job.
* DisneyDeath: In the episode "It's Time". [[spoiler:[[BackFromTheDead He came back to life via time travel.]]]]
* FoolishSiblingResponsibleSibling: The foolish sibling to Don.
* FragileSpeedster
* FunnyAnimal: See above. He digs through trash and runs on all fours when in a hurry.
* GenreSavvy: In the episode "Temp Check", he describes himself as a 'lovable scoundrel'.
** He's become this in regards to Mordecai's relationships, able to see them clearly when even Mordecai himself cannot. It becomes a plot point when Mordecai nearly strands himself in space to avoid dealing with his feelings towards CJ and Rigby's able to talk him back.
* TheGlassesGottaGo: Rigby seems to be a firm believer of this since he thinks [[spoiler: Eileen is hot without her glasses on.]]
* GreenEyedMonster: Most of his idiotic schemes and troubles are motivated by his jealousy of some thing or another.
* HairTriggerTemper: Whenever called out or trolled.
--> '''STOP TALKING!!!'''
* {{Hypocrite}}: In "Bet to be Blonde", he makes fun of Mordecai and the Blonde Men for being blonde, but it's revealed that he used to have blonde hair during high school.
* {{Jerkass}}: Pre CharacterDevelopment, after which he becomes a...
* JerkWithAHeartOfGold: Driven home in the hot dogs episode, where Rigby truly seems to care for Mordecai after they both get trapped in the freezer.
** Also in the episode "A Bunch of Baby Ducks", where Rigby insists on keeping the ducks, and calls them his.
** Another example is at the end of "Do Me a Solid" where Rigby destroys the only video evidence of the humiliating solid he made Mordecai do.
** The first Halloween special drives home Rigby's dependency on his friends. The characters all share a horror story for the group: Pop's idea of horror is a scary doll drawing on people's faces. Muscle Man's idea of horror is dying in a crash. Rigby's idea of horror? Everyone BUT him dying and being left alone. He dies too, at the end, by means of a giant egg. This gets worse when you find out later he is deathly allergic to eggs.
** In "Video Game Wizards", he was deeply heartbroken when Mordecai chose Skips as his partner instead of him.
** Rigby is a total jerkass in "Wall Buddy", for the sole reason that Mordecai doesn't help him tidy up their room. This is in stark contrast to his behavior in most previous episodes, but you could find it [[RuleOfFunny hilarious]].
* JerkWithAHeartOfJerk: Rigby wouldn't dare help anyone if Mordecai didn't force him.
* KnowNothingKnowItAll: Particularly in "Rigby's Body," where, even after his body literally quits on him, he stubbornly insists that he was right about everything.
* LameComeback: He has trouble arguing without resorting to one of these.
* LargeHam: A big ham in a tiny body.
* ManChild: He may be 23, but he acts like an out-of-control teenager most of the time.
* NeverMyFault: If he can, he'll try to avoid taking blame for any of his mess up. And he can be ''really'' stubborn, so much so that he'll only admit when he's wrong when the problem he caused has grown too large to be controlled.
* NiceJobBreakingItHero: He and Mordecai are responsible for a ''lot'' of the weird problems that occur in the series. Though a good majority of the problems come from his end due to his immaturity.
** "I can fix it! I can fix it!"
* NoYou: Practically his catchphrase when he argues with someone.
* PingPongNaivete: Despite the AllMenArePerverts joke above, he doesn't understand "why people ''really'' go to concerts."
* RascallyRaccoon: To an extent.
* RedOniBlueOni: The red to Mordecai's blue.
* RunningGag: He can never win at punchies.
** As a Foil to the above gag, Rigby frequently wins against Mordecai in Rock Paper Scissors.
* ShesNotMyGirlfriend: Will deny any sort of feelings for Eileen despite spending almost all his time with her when not with Mordecai.
* ShipperOnDeck:
** For Mordecai and Margaret.
** He's switched to Mordecai and CJ, prefering CJ to Margaret.
* SiblingRivalry: Hates his brother Don for being more popular than him, stealing his friends, and [[spoiler: [[BigLittleBrother being mistaken for Rigby's big brother when ''Rigby'' is the older brother.]]]]
* TheSlacker: Though, in some instances (like "Death Punchies" or "Caffeinated Concert Tickets") he's shown to have all the ambition necessary to achieve his goal.
* TemporarilyAVillain: DependingOnTheWriter. He had done some villainous deeds which are not acceptable.
* TooDumbToLive: Once tried to eat a huge omelette to earn a free hat, despite being deathly allergic to eggs.
** "I thought if I ate really fast, maybe I wouldn't notice."
** Played for laughs at times. He also appears to have a knack for dousing life threatening fires with lighter fluid.
* TookALevelInBadass: To the point of going DrunkWithPower [[spoiler: until Mordecai does it too.]]
* TookALevelInJerkass: In ''Do Me a Solid''. Takes an even worse one in ''Wall Buddy''.
* TookALevelInKindness: Towards Eileen. At first he was a jerk to her, but as the series goes on he's warmed up to her and now seems to legitimately care about her.
* TotallyRadical: Like Mordecai, says "dude" and "man" a lot.
* {{Tsundere}}: Is heavily implied to be this, especially towards [[ImpliedLoveInterest Eileen]].
* UnsympatheticComedyProtagonist: Most of the time. He's reckless, selfish and immature.
* VerbalTic: Also prone to "Hmm"ing a lot.
* VitriolicBestBuds: With Mordecai. Eventually he also befriends Benson and Muscle Man, despite not getting along well at first.
* WeirdnessMagnet

!!!Voiced by: Sam Marin
!!!Debuted in: "Pilot"/Season 1, "The Power"
[[caption-width-right:200:"Get back to work or YOU'RE FIRED!"]]

An anthropomorphic gumball machine, and Mordecai and Rigby's boss. Although he generally seems mildly annoyed, at the worst he can get really pissed if Mordecai and/or Rigby have messed something up.

* AllDrummersAreAnimals: Subverted in "150-Piece Kit" when the audience finds out that the man behind Hair to the Throne's famous drum solo was ''Benson.''
* AnimateInanimateObject: He's a talking gumball machine.
* AntiHero: He's nice sometimes. Other times he can be a weapons grade prick.
* AntiVillain: Treats Mordecai and Rigby like crap most of the time, but he's just doing his job.
* AxCrazy: His HairTriggerTemper is so extreme that he reaches many times a psychotic behavior.
* {{Badass}}: From ripping a phone off the wall with one hand to becomming a super saiyan of rage. See BigDamnHeroes.
* BerserkButton: Getting prank calls, apparently.
** Whatever you do, DON'T THROW TRASH AT HIM.
** Starts shouting in {{Angrish}} and gives chase when Rigby says he's "[[GeorgeJetsonJobSecurity all talk]]" in "A Bunch of Full Grown Geese".
* BigDamnHeroes: In "Benson Be Gone" he returns to the park just in time to [[spoiler: save it from Susan]].
** He also [[spoiler: arrives with his drum set at the last second, [[PowerOfRock giving the cast enough music power to destroy the Summertime Lovin' cassette.]]]]
** And again in "Stick Hockey" when [[spoiler: he arrives just in time to finish Mordecai and Rigby's stick hockey death match and is revealed to be a master at the game.]]
** Got yet another one in "Cool Bikes" when he [[spoiler: saves Mordecai and Rigby's lives by attacking the judge that was sentencing them to death and aiding in their escape.]]
** He got a small (yet awesome) one in "Karaoke Video". Mordecai and Rigby are attempting to steal the video of them dissing on their coworkers. Some brawls between the bars employees and them eventually turn into an all out bar brawl. Near the end it shows Benson hopelessly looking at the ridiculous warfare just as the tape lands in front of him. He picks it up curiously and the owner of the bar punches him in the face and orders him to give it back. [[spoiler: He then smashes the karaoke tape right into the owner's face, knocking him out and destroying the tape in the process. He basically saved Mordecai and Rigby's necks from himself without even realizing it.]]
---> [[spoiler: '''Benson''': You want it?! FINE! TAKE IT THEN!]]
* BreathWeapon: Benson unleashes a torrent of pure, pent-up rage at Mordecai and Rigby during "Think Positive" in the form of a mouth laser.
* TheCaptain
* CantHoldHisLiquor: Has a weakness for [[GRatedDrug chicken wings]].
* CatchPhrase: "Get back to work!" and "Clean up this mess!" (both of which are usually followed by "Or you're fired!")
* TheCavalry: [[spoiler: The guys are losing to a physical manifestation of an EarWorm that they're battling by playing a counter EarWorm. When Benson arrives, Mordecai assumes he's there to yell at them for messing up the park with their battle. He is there to yell at them, but for forgetting a key part of an EarWorm: the beat from the drums which he plays.]]
* CharacterDevelopment: He's noticeably more tolerant of Mordecai and Rigby after "Benson Be Gone", not getting as angry at them for when they mess up. [[spoiler:He even came to their rescue in "This Is My Jam"]].
** Also shows in "Jinxed" when he subverts his RantInducingSlight because they apologized for slacking off, where before he'd not have given them the time of day. He ''did'' lose it earlier in the episode when Rigby was intentionally enraging him trying to break his jinx, but Benson didn't take it out on Rigby and instead vented his rage elsewhere.
** Newer episodes even had him lead the group in downtime activities, like a weekly game night and paying for everyone at a bar, even Mordecai and Rigby.
** It's revealed in "Stick Hockey" that [[spoiler: he used to be a champion stick hockey player until ten years prior to the episode when his apprentice Dave was killed in the final round of a tournament. Now he sees himself as a loser who wasted his life on stick hockey and now he's wasted his life in a dead-end job.]]
** "Think Positive" revealed that Benson of all people was [[spoiler:TheQuietOne in his family, and his father taught him that the only way to get stuff done is with a HairTriggerTemper. His giant rant at the end had him imply that he always [[JerkWithAHeartOfGold holds off on firing Mordecai and Rigby because he really just wants to teach them to be more responsible]]]].
** "150-Piece Kit" reveals he performed a legendary drum solo for the band Hair to the Throne, one everyone though was done by the band's drum machine. [[Awesome/RegularShow He then proceeds to perform said solo again in front of the whole park, proving he did it.]] The episode also has him turning down an offer to tour with Hair to the Throne to keep working at the park showing how much he loves the place.
* TheComicallySerious
* ADayInTheLimelight: "Benson Be Gone" was his first one, but "Think Positive" was more about ''his personality''.
* DeadpanSnarker: He sometimes leans on this especially when the HaHaHaNo trope is used.
-->'''Rigby''': And we'll be all like "In your face!"
-->'''Benson''': [[SarcasmMode Haha]], and I will be all like [[SuddenlyShouting GET BACK TO WORK!]]
* DependingOnTheWriter: Benson's characterization ranges from a JerkWithAHeartOfGold to a full-blown JerkAss that [[HairTriggerTemper overreacts to everything]].
* DysfunctionalFamily: Benson's family taught him to yell whenever he wanted something, which turned him into a big anger ball.
* EarlyBirdCameo: First appeared in [[ "2 in the AM PM'']], one of J. G. Quintel's first short films, in the gas station clerks' acid-induced hallucination.
* EnragedByIdiocy: Oh so easily.
* {{Expy}}: Big rounded head, large nose, GrumpyBear attitude. Sounds familiar to [[SpongeBobSquarePants Squidward]], right?
** If it's not a coincidence, he started off as being based off of Sam Marin.
* FreudianExcuse: "Think Positive" implies that Benson is so quick to raise his voice because his father told him, "You'll never get anything you want in this world if you don't yell for it."
* GagNose
* GeorgeJetsonJobSecurity: He threatens to fire Mordecai and Rigby on a daily basis.
* GoodIsNotNice: He often threatens to fire Mordecai and Rigby, but all he's really doing is his job. He's only friendly when things aren't out of hands.
* GrumpyBear
* HaHaHaNo
* HairTriggerTemper: Has very explosive outbursts that often end with "'''''...OR YOU'RE FIRED!!'''''" Generally seems to be ready to blow his cool at the drop of a hat anyway.
* HighPressureEmotion: His gumballs turn red when he's angry.
** [[spoiler:"Think Positive" makes this trope literal. If he holds in his anger too long, he starts burning things at his touch and destroying everything until he's let it out.]]
** [[spoiler: And even then, at the highest pressure, he turns flaming gold.]]
* JerkassHasAPoint: While he can be quite obnoxious, it's understandable since Mordecai and Rigby rarely do their job and are almost ''always'' slacking off. [[StatusQuoIsGod You just have to wonder why he hasn't]] [[JerkWithAHeartOfGold fired them for good yet, though.]]
* JerkWithAHeartOfGold: Despite his extremely short temper and being constantly annoyed by Mordecai's and Rigby's antics, when he's in a good mood he'll treat them very well, and he considers all of his employees to be friends.
** On a couple of occasions Benson has claimed that [[ToughLove he does something tough on Mordecai and Rigby out of concern for their future and wants to instill some sense of responsibility in a pair of irredeemable slackers]].
** It's still there, though, as seen in "Stick Hockey", where he throws out Mordecai and Rigby's stick hockey game (even though they finished all their jobs) just because he didn't think they'd finish (although he ''does'' regret his actions, and even helps get it back).
*** At the end he admits he did so because he was afraid that they'd end up wasting their lives playing the game like he felt he did with a part of his own.
* KnightInSourArmor
* LargeHam: Having a Hair Trigger Temper does not help his case. He's even more rowdy when intoxicated.
* MeanBoss: Benson arguably skirts this line. He yells a lot and constantly threatens to fire his employees, but it is fairly clear that he runs a tight ship and his constant yelling is somewhat justified. Furthermore he claims that his aggressive attitude is him trying to hammer a sense of responsibility into Rigby and Mordecai, and he does reward his employees every once in a while.
** He walks the talk - he'll genuinely praise his employees, Mordecai and Rigby included, when he feels they've done a good job. The ending of the episode "Grave Sights" is a good example of this.
** He's also fairly nice to Skips (who is hard-working) and Pops. He's also a bit strict with Muscle Man, but that's more because he's obnoxious (although he normally does his work).
* NiceGuy: Whenever he doesnt have to deal with Mordecai & Rigby.
* NeverMyFault: When his car ends up missing and the cops don't do anything to help him, he resorts to hiring a bounty hunter from the future to find the perpetrators and his car. It turns out, however, that the perpetrators were Mordecai and Rigby, who secretly took it for repairs after breaking the windshield of his car. To make matters worse, as part of the terms, [[BloodKnight the bounty hunter]] [[IrrevocableOrder was allowed to do as he wished when he found the thieves]], regardless of the outcome, which in this case did not necessitate such a thing by any measure as the car had been returned good as new. In the meantime, the bounty hunter ends up wrecking the house in pursuit of Mordecai and Rigby. Even after Benson called him off, the bounty hunter ends up accidentally destroying the car. Benson sticks Mordecai and Rigby with the tab even though it was his idea to send in the bounty hunter in the first place. Then again, this whole mess would have never happened if Mordecai and Rigby just [[CouldHaveAvoidedThisPlot told Benson that they damaged his windshield or that they took his car in the first place]].
** It's brought up again in "Gold Watch", where he immediately curses Mordecai and Rigby after waking up in the desert because of his own drunken recklessness.
* NoIndoorVoice: If you get him really mad, of course. [[spoiler:"Think Positive" made it loud enough to make Mordecai and Rigby go deaf!]]
* NoodlePeople: He has long, gangly arms and legs.
* NotSoAboveItAll: [[spoiler: '''OOOOOOOOOOOOOOH'''!!]]
** Calvin Wong's Formspring also spoiled (by accident) that [[spoiler: he's a huge fan of rock music, in particular "Foghat, Hall and Oates, Asia, Toto, and Phil Collins."]]
* NotSoStoic: As seen in his scene in the ending of "Mordecai and the Rigbys" where he nonetheless gives them both a standing ovation after their disastrous performance and Mordecai's speech.
** Seen again in "This Is My Jam". He's initially angered by the omnipresent ear-worm, but willingly joins in on drums to help Mordecai's improvised band defeat it.
** In Carter and Briggs", he lets Mordecai and Rigby use the park cart for a contest where the price is a supporting role in their favorite cop show, on the condition that they wear the park's official shirts on TV if they win.
* ObnoxiousSnarker: Sometimes borders on this, especially if it's a [[{{Dramedy}} bad timing]].
* OnlySaneMan: For a relative use of "Sane".
* PermaStubble: WordOfGod is that his gumballs are supposed to resemble this, as a visual sign that he is over-worked.
** Which would technically mean that, in Benson's flashback in "Take It Easy," not only did he have stubble 'as a child,' but his mother also had stubble, and his sister's face was almost entirely covered in it, seeing as her "gumball line" was above her eyes. Scary.
* PerpetualFrowner
* PrematurelyBald: A flashback revealed that a younger Benson was humiliated on a game show, and the stress was so intense that he instantly lost all of his brown hair.
* RantInducingSlight: Benson doesn't get REALLY upset at Mordecai and Rigby until ''after'' whatever horrible situation they created has been resolved.
** Decreased in number after "Benson Be Gone", after which it happens noticeably less often.
* TheReasonYouSuckSpeech: Gives a truly epic one to Mordecai and Rigby in "Think Positive":
* RedBaron: [[spoiler: Benson was once known as the [[NamesToRunAwayFromReallyFast Death Dragon]] in stick hockey circles.]]
* RetiredBadass: Was an expert in Death Stick Hockey and played what is considered the world's greatest drum solo.
* SeenItAll: When [[MundaneMadeAwesome the usual daily crisis happens]], he tends to not question the fact that it's happening so much as how Mordecai and Rigby caused it. For example, when Mordecai and Rigby turn up with a [[HumanPopsicle thawed-out caveman]], he simply tells them to get rid of him because he won't be covered by the park's insurance.
* SoreLoser: He takes dodgeball [[SeriousBusiness very seriously]]. He also [[{{Understatement}} doesn't take losing very well]].
* TheSlacker: If you can believe it, even more so than Mordecai and Rigby. In "Benson Be Gone," the two try to teach Benson it's okay to slack off a little as long as you get back to work, but Benson takes this as meaning it's perfectly fine not to work at all. If he doesn't have a constant stream of work, he won't work at all.
** Justified as he used to [[spoiler: spend his days as a stick hockey player which is not known for bringing in money. He was a drummer which is less of an example, but given what [[SexDrugsAndRockAndRoll rock does to a guy...]] Benson outright states he's wasted his youth.]]
* TeamDad: Despite his annoyance with the main duo and the rest of his employees at times, he's nonetheless very protective of them, evidenced in episodes such as "Benson Be Gone", or "Stick Hockey"
* TookALevelInBadass: Arguably in his DayInTheLimelight episode "Benson Be Gone", especially when he [[spoiler: takes a limo and tries to run down the One-Winged Angel version of Susan, dying in the process.. Leon takes his place at the last minute, but still!]]
** Benson takes another level in badass in "Stick Hockey", where [[spoiler: the game is apparently an underground bloodsport complete with rampant death, burning pits, and lots of spikes.]]
* TalkingInYourSleep: In "Saving Time", Mordecai and Rigby notice him doing this while they break into his house.
* TookALevelInJerkass: In later episodes, he's gotten a lot more aggressive and openly spiteful towards Mordecai and Rigby.
* TookALevelInKindness: As above, it really varies according to the writers as whether he's nice or not.
* VagueAge: WordOfGod revealed that Benson is anywhere between the ages of 25 and 35.

!!!Voiced by: Sam Marin
!!!Debuted in: "Pilot"/Season 1, "The Power"
[[caption-width-right:300:"Good show, jolly good show!"]]

The son of the park's wealthy owner who's been sheltered all his life. He's a humanoid lollipop from Lolliland. He's mostly there to be comic relief. Also, Mordecai and Rigby can get away with almost anything around him because he doesn't know better. The episode "Dizzy" reveals that he has an extremely dysfunctional relationship with his father, who's as scary as Pops is kooky.

* {{Adorkable}}: Incredibly so. His childlike demeanor, antiquated linguistics and kind personality make him very endearing.
* TheAllegedBoss: He's technically the boss of the park but rarely asserts his position and acts more like a co-worker.
* AnthropomorphicFood: Arguably.
* Badass
** BadassGrandpa: If being over 100 years old, and being able to [[spoiler:best ''a freaking '''polar bear''' '' in wrestling]] doesn't qualify him...
** CrouchingMoronHiddenBadass: In "Really Real Wrestling" it turns out he used to wrestle. Turns out he's still pretty good at it too.
* BarbieDollAnatomy: Seen when naked Pops is falling down the cliff in "Brain Eraser".
* BenevolentBoss: He's technically the head of the park, but he lets Benson run things and acts like any other worker. He treats everyone with kindness and respect. Just listen to how he speaks to Benson when he politely tells him not to yell at Rigby.
* BornInTheWrongCentury: Though, since he is from Lolliland, it's possible that his way of dress and behavior is normal where he's from.
** Perhaps not--as seen in "Skips Vs. Technology", he's over 100 years old.
* CatchPhrase: "(Jolly) good show!"
** Sometimes turns into "Bad show... very bad show" when he's sad.
* CharacterOverlap: He first appeared in one of two pre-''Regular Show'' sketches that JG Quintel made called [[ "The Naive Man from Lolliland."]]
** In "Don", he believes lollipops are the same thing as money, and are therefore suitable for paying bills, which gets the park into some trouble. The exact same situation is the plotline for the aforementioned sketch.
*** Pops "generally" considers lollipops to be the equivalent of money. "The Power," among other episodes.
** He briefly appears in the other JG Quintel sketch (2 in the AM PM) as one of their hallucinated forms.
* ChildhoodBrainDamage: Mordecai and Rigby travel back in time and meet a younger Pops, acting lucid and sane, unlike the {{Cloudcuckoolander}} he is in the present. Later during a car chase, they accidentally hit Pops, who then starts giggling like present-day Pops.
* {{Cloudcuckoolander}}: Pops' flighty behavior is said to come from either getting run over by a cart or by a brain tumor from excessive cell phone use.
* CoolCar: His schway [[FlyingCar flight capable]] ride, Carmanita.
* CoolOldGuy: Maybe.
** Also, in the karaoke episode, Pops punches a guy while singing without even being fazed.
** Also in his CharacterOverlap above, he [[spoiler: wipes the floor with three guys. One them the size of a wall.]]
* FragileFlower: A rare male example that isn't always played for laughs- in fact, seeing Pops cry is absolutely [[TearJerker heartbreaking]] sometimes. Pops is very sensitive and it doesn't take much to make him cry. When someone ''does'' greatly upset him, his friends immediately come to his aid and stick up for him.
* FunnyForeigner
-->"Oh, I ''adore'' Rock Paper Scissors! Except where ''I'' come from, it's called 'Quartz Parchment Shears'"!
* GeniusDitz: [[spoiler: His wrestling skills.]] Also, his cherry tart, which one the pie contest for ''ten years in a row''.
* TheHeart: Despite his many quirks, Pops is a sweet, gentle, child-like man who's the type to have a kind word for anyone when they need it, and to help a baby bird back into its nest. ''Everybody'' who works for the park loves and wants to do right by the guy, and messing with him is a collective BerserkButton.
* KindheartedSimpleton: The guy's a total flake (and also somewhat of a crybaby,) but is easily the nicest character in the whole show.
* LetsGetDangerous: [[spoiler:"...Who wants to wrestle?" Curbstomping ensues.]]
* LiteralMinded: Inverted by Pops.
-->'''Mordecai:''' That taxi's yellow!
-->'''Pops:''' My taxi is no coward, I assure you!
* ManChild: He's a (super-)centenarian with the mind of a small child. However his vocabulary is very formal.
* MeaningfulName
* MissingMom: We first see his mother in 1879 in "Skips vs. Technology". But in the present time, we never see his mother throughout the show.
* MoralityPet: To pretty much the entire Park crew, just see the lengths they go to get him his birthday present in "Fuzzy Dice".
* MundaneObjectAmazement: Pops can summon up an inordinate level of awe for even the most boring task or object.
* MusclesAreMeaningless: Much stronger than his lanky 100+ year old frame suggests.
* NiceGuy: He is probably the single kindest and sweetest character in the entire show. Almost absurdly so.
* NiceHat
* NoSocialSkills: Sometimes has touches of this. Justified in that he seems to have the maturity of a five-year-old.
* PointyHairedBoss: He's extremely negligent and a more than a few episodes stem at least in part to him letting something happen or trusting Mordecai and Rigby too much. He also has a problem with failing to see how much Mordecai and Rigby fail as employees.
* ShelteredAristocrat
* ShownTheirWork: His really real wrestling is actually fairly accurate. Notable moments include dropping Four-Armageddon with a single leg takedown, the Fire Marshall and Hissy-Fit with five-point throws, and finishing Four-Armageddon with a triangle choke.
* SpoiledSweet: [[AccidentalPun No pun intended]].
* SupremeChef: His cherry tart was the best pie in the pie contest, and he's won said contest 10 years in a row.
* TenderTears: Frequently.
* TookALevelInBadass: [[spoiler: In "Really Real Wrestling".]]
* UpperClassTwit
* VocalEvolution: His voice was lower and more soft-spoken in "The Naive Man from Lolliland". It seems to become a little more high-pitched and screechy through each season.
* WellDoneSonGuy: His scary father, as seen in "Dizzy".

!!!Voiced by: Creator/MarkHamill
!!!Debuted in: "Pilot"/Season 1, "The Power"
[[caption-width-right:171:"I've seen this before."]]

A yeti who also works at the park. He seems the most tolerant of the crazies he works with, and is often quick to find a solution to any problem.

* TheAce: Most of the time.
* {{Badass}}: He's been adventuring and fighting evil for over 100 years.
** CulturedBadass: Is actually quite nice and polite as well as being a good fighter.
* TheBigGuy: A unique combo of Class 2 and 5.
* BigfootSasquatchAndYeti
* BullyHunter: In "Skips' Story", he was the only one in school to stand up against Klorgbane and challenge him to a fight.
-->'''Walks''': Walks never walks away from a bully.
* BunnyEarsLawyer: A highly intelligent yeti who gets around by skipping. Yeah, perfectly normal.
* TheComicallySerious: He is always serious despite this.
* CoolOldGuy: The oldest guy in the cast and quite a cool customer.
* DefrostingIceKing: Gruff, quiet and sardonic. But fun if you get to know him.
* TheEeyore
* EveryoneWentToSchoolTogether: In "Skips' Story", he attended high school with Gary, the Guardians of Eternal Youth, and Klorgbane during the 18th century.
* GeniusBruiser: At times Skips seems to be able to improvise very quickly, as seen in ''The Power'' near the end. Likewise, his quick thinking brings about the avatar by which Rigby destroys the Destroyer of Worlds.
* GentleGiant: Is one of the nicer characters on the show, as well as the strongest.
* HalfDressedCartoonAnimal: Rarely seen with a shirt on.
* '''HeroicBuild''': Just look at the guy.
* IHatePastMe: Averted when he meets his teenage self in "A Skips in Time". Walks, before Skips changed his name, doesn't want to be like his present self because he believes he has become boring and refuses to change his name to "Skips". Skips was angry at first but he understands that he's a teenager and he'll grow out of it.
* KryptoniteFactor: Even with his immortality, it turns out that an excess of stress without proper management is the only thing that can potentially kill him. [[spoiler:[[AnthropomorphicPersonification Unless he kills it himself.]]]]
* TheLostLenore: [[spoiler: Mona, his high school sweetheart who was killed when she pushed him out of the way of falling rubble caused by Klorgbane's attack on the prom.]]
* MeaningfulRename: He always skips rather than walking. [[spoiler: It turns out his real name is not Skips, but Walks. He changed it because he got tired of everybody asking him why he skips everywhere instead of walking]]
** That turns out to be partily true [[spoiler: in ''The Diary'', he reveals he likewise skips in memory of a girl he once loved but lost in the past. ''Skip's Story'' goes into more detail about this.]]
* MrExposition: With his SeenItAll nature, he usually provides info on whatever threat the park is facing.
* MrFixit: According to "Skips vs. Technology", he's in charge of basically any repair work needed around the park, a role he fills quite well... at least, when it comes to physical stuff. Fixing a malfunctioning computer seems to be a bit beyond him.
* MyGodWhatHaveIDone: Gets this in "Over The Top" after [[spoiler:killing Rigby]]. He's so guilty that he [[spoiler:puts his eternal soul on the line to win Rigby's soul back from Death.]]
* NiceGuy: Actually quite nice, although [[TheStoic he's always serious.]]
* NiceJobBreakingItHero: Um, [[spoiler:KILLING Rigby]] in the arm-wrestling episode.
** Again in Sugar Rush, a fact that Rigby chides him about.
* OlderThanTheyLook: He made a deal in order to obtain eternal youth.
** To the point of Really700YearsOld (over 220 years at least).
*** It's even foggier now with Skips' Story revealing how he got his immortality, but doesn't reveal when exactly the story takes place.
*** He seems to have been born in the 18th century and witnessed the American Revolution, making him at least two-and-a-half centuries old.
* OnlySaneMan: Along with Benson.
* PerpetualFrowner: Rarely seen smiling, [[NiceGuy but don't let]] [[GentleGiant it trick you.]]
* RageBreakingPoint: When Klorgbane had a hand in Mona's death, Skips sent him flying.
* ReasonableAuthorityFigure
* SeenItAll: Very few things seem to faze him and he somehow knows just how to deal with all the insanely weird things the park has to deal with. Justified possibly due to OlderThanTheyLook.
* TheSmartGuy: Fills this role whenever Muscle Man has TheBigGuy role. He can fix almost anything (except computers), and comes off as the wisest of the team.
* TheStoic
** NotSoStoic: Has moments were he's smiled and broken his stoic personality.
* SuperStrength: Those muscles aren't just for show.
* TopHeavyGuy: Big time.
* VocalEvolution: His voice was a lot more gruff in the pilot.
* WalkingTechbane: As shown in "Skips VS Technology" he can fix almost anything, except computers.

[[folder:Muscle Man]]
!Mitch "Muscle Man" Sorenstein
!!!Voiced by: Sam Marin
!!!Debuted in: "Pilot"/Season 1, "Just Set Up the Chairs"
[[caption-width-right:219:"You know who else is a troper? MY MOM!!"]]

An ironically-named, short, out-of-shape guy, who has a hicklike lifestyle.

* {{Acrofatic}}: There are times, especially during an episode's climax, where Muscle Man shows this. Despite his short and fat build, he seems to have super-strength.
* AmbiguouslyHuman: Muscle Man looks more humanoid than anyone else in the regular cast (possibly except for Eileen, who has been identified as a mole, and Pops who is supposed to be a lollipop), but he's green. "Trucker Hall of Fame" showed that Muscle Man's brother's skin was white and his hair was brown (just like his brother and father).
* AmbiguouslyJewish: Has an Ashkenazi[[note]]Ashkenazi Jews are the ones who can trace their ancestry to the indigenous Hebrew speaking peoples of Canaan in South Western Asia, and migrated to non German-speaking areas, including Bohemia, Hungary, Poland, Belarus, Lithuania, Russia, Ukraine, Romania, and elsewhere between the 11th and 19th centuries.[[/note]] last name ("Sorenstein"), and in the Christmas Special, his sweater has a dreidel on it.
* AscendedExtra: Since season 2.
* BerserkButton: Don't spill soda on him. It will most certainly lead to your DisproportionateRetribution.
* BewareTheSillyOnes: Muscle Man may seem like an idiot. But with the occasional bout of SuperStrength, a serious vindictive streak, and [[TheChessmaster Chessmaster]] level smarts at times, it's wise to avoid his ire.
* {{Catchphrase}}: "You know who else [[MadLibsCatchphrase __________]]? MY MOM!" and "[[OhCrap Oh no]], bro!"
* CharlesAtlasSuperpower: Do NOT get Muscle Man mad. His strength increases to insane proportions when he does for some inexplicable reason.
* TheChessmaster: [[spoiler: Surprisingly, Muscle Man is more than capable of pulling off a multilayer ThePlan.]]
** An example of this is in 'Trailer Trashed', where he [[spoiler: fakes out a false health inspector who's trying to get his trailer, by running an empty truck to the border. Turns out, the trailer was back at the Park, being guarded by High Five Ghost.]] None of the other park employees were in on it, prompting Rigby to comment, "Remind me to never touch Muscle Man's stuff."
* DrillSergeantNasty: Muscle Man in "Muscle Mentor". [[spoiler: And it actually works.]]
* EvenEvilHasStandards: He maybe a prankster, but Muscle Man was ashamed of himself when Pops got hurt from of his actions.
* FatBastard: When he's the episode's antagonist.
* FanDisservice: PlayedForLaughs.
** {{Gonk}}: The most consistently unattractive man in the cast.
* FatIdiot: Gradually got away from the idiot part through CharacterDevelopment.
* FatAndProud: He used to be a bodybuilder. But doesn't give a damn that he's a fat dude now.
* GagBoobs: Muscle Man's [[Film/FightClub bitch tits]] (which he acknowledged on "Party Pete" in his line, "It takes guests with breasts, and mine don't count"). He even got smacked in the face with them in "Rage Against the TV".
* GeniusDitz: "Exit 9B" shows that he's actually smart enough to lead a college lecture on quantum physics. Either that, or GBF Jr's brainwashing somehow increased his intelligence.
* GenreSavvy: "This is the future, bros. There's gotta be a time machine!" [[spoiler:He was right.]]
* IronicNickname: He seems to be anything but muscular. It turns out that he used to be [[MeaningfulNickname very muscular]], and even though he's fat now, he's still ridiculously strong.
* {{Jerkass}}: Originally, Muscle Man was a {{Jerkass}} to Mordecai and Rigby, culminating in "My Mom". However, [[CharacterDevelopment he's become]] a nicer person since then, willingly working with Mordecai and Rigby in "The Night Owl".
** JerkWithAHeartOfGold: Although he's still an immature idiot, he's never mean towards women. Plus, he started to willingly work with Mordecai and Rigby and view them as friends.
* LargeHam: "WOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!"
* LetsGetDangerous: Both of them at the end of "The Night Owl".
* MeaningfulName: He actually is very muscular, but it's covered by a thick layer of flab.
** And as shown in "Slam Dunk" he's actually a good athlete, when he smokes Mordecai and Rigby at basketball. Several times.
** In "The Night Owl", he defeats several guards by physical means and knocks out The Night Owl with a single punch.
** Considering the fact that he throws trees and boulders effortlessly in ''Starter Pack'' Muscle Man might have finally lived up to his name.
** In "Power Tower" it's revealed that the nickname is from his bodybuilder days before he let himself get out of shape.
* MyGodWhatHaveIDone: Muscle Man get this in prankless after a prank gone wrong nearly killed Pops and swore off pranking (Which is bad since a rival park restarted a VERY vicious war.) the only way to snapped him out of it was tricking Muscle Man that the rival park hurt Pops in a prank as well.
* [[OhCrap Oh no, Bro!]]
* OnlyKnownByTheirNickname: Averted; his real name of Mitch Sorenstein is revealed in "Muscle Woman".
* ThePrankster: He's apparently the best in town.
* RoaringRampageOfRevenge: [[spoiler:Goes ''batshit'' insane once Mordecai & Rigby prank him for pranking Thomas nonstop by telling Thomas did it to make him look good. It all turns out to be a big prank against the duo...though Thomas loses his car.]]
* ScrewTheRulesIHaveConnections: As one episode shows, Muscle Man has a lot of friends around town. Heck, a police officer chases afters him just to tell him how awesome he is.
* SoreLoser: Muscle Man. He will someones life an utter hell if he loses at something.
* StealthPun: Muscle Man is a [[AmbiguouslyHuman green-skinned humanoid]] who likes to mess with and torment the other characters. [[spoiler:He's a troll, both [[AllTrollsAreDifferent literally]] and [[{{Troll}} figuratively]].]]
* TheStoner: The green complexion, pink eyes, man boobs, chubby build, and Pink Floyd poster do point to signs that Muscle Man could be on drugs (most likely marijuana, since all of those are signs or traits associated with pot use), but nothing has been confirmed by the creators (though given the strong adult undercurrent of the show, it might be true).
* StoutStrength
** SuperStrength: When angered, he's able to rip ''buildings'' out of the ground and throw them.
* TalkToTheFist: In "Night Owl", [[spoiler:after returning to the past after the title character froze him, Hi-Five, Mordecai, and Rigby for several hundred years, the Night Owl starts chewing them out for ruining his plan. So Muscle Man knocks him out cold mid-rant.]]
* ThoseTwoGuys: Muscle Man and Hi-Five Ghost
* TookALevelInKindness: Especially in "The Night Owl."
* TokenHuman: Muscle Man. [[AmbiguouslyHuman Maybe.]]
* VocalEvolution: Muscle Man sounds quite different in a few early episodes, especially "Rigby's Body".
* YourMom: Inverted; Muscle Man makes "My Mom" jokes instead of "Your Mom" jokes. Rigby and Mordecai even try to tell him that the "your mom" jokes work better. "Trucker Hall of Fame" reveals that the "My Mom" jokes were from his father's "My Wife" jokes.
* XanatosGambit: Some of the pranks he pulls off nearly require clairvoyance with their absurd specificity.

[[folder:Hi-Five Ghost]]
!Hi-Five Ghost
!!!Voiced by: J.G. Quintel
!!!Debuted in: "Pilot"/Season 1, "Just Set Up the Chairs"

Muscle Man's perpetually nervous ghost-looking friend [[ExactlyWhatItSaysOnTheTin who hi-fives him a lot]].

* {{Adorkable}}: "The Postcard" sets him up to be this.
* ADayInTheLimelight: "The Postcard". Only took five seasons...
* BirdsOfAFeather: With Celia. They love the same coffee shop, down-tempo electronica, the same music album, watching animals in the aquarium, and they don't like the food in Wing Kingdom. But unfortunately, none of them had cellphones back then.
* BoyMeetsGirl: With Celia.
* IntangibleMan: At least when he wants to be. Usually demonstrated when someone tries to punch him. He'll let it pass through, then strike back.
** Oddly enough, he fails to escape after being gripped by the evil living pumpkin in "Terror Tales of the Park III", despite Mordecai even shouting out: "Fives! Just phase through, man!"
* InterspeciesRomance: With Celia, a human.
* MultiArmedAndDangerous: Hi-Five Ghost (and his family) can apparently form extra arms when needed. HFG once appeared with ''five''.
* ThePromise: He and Celia both agreed to meet up again when she finishes her schooling and if they're both single by sending him a postcard to let him know she's back in the country.
* TheQuietOne: Hi-Five Ghost spoke only one full sentence in the entire first season. The episode "Muscle Woman" has Fives talk more than usual due to Muscle Man isolating himself, implying that he usually doesn't talk because Muscle Man just does all the talking for him.
** As one episode shows, apparently he doesn't talk because he's jinxed and Muscle Man will punch him if he ever talks around him. Rigby broke his jinx and afterwards he talks much more often.
* SatelliteCharacter: High Five Ghost is excluded from a lot of the park group's activities, serving mostly as an accessory to Muscle Man. [[ A cut gag from one ending storyboard lampoons this.]]
** "Exit 9B" actually had to have brand new scenes when his memory was restored, because he's so ancillary.
* OurGhostsAreDifferent: It's not clear whether HFG is living or undead. His family also consists of ghosts, and they all live normal lives.
* OutOfFocus: '''''Oh, yeah'''''.
* VocalEvolution: When J.G. Quintel took over for JeffBennett, Quintel's voice zigzags between sounding like a pitched-up Mordecai and sounding like himself during the "embarrassing voice cracking" stage of male puberty.

!!!Voiced by: Creator/RogerCraigSmith
!!!Debuted in: Season 4, "Exit 9B"

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

* AffectionateGestureToTheHead: He is officially welcomed to the park staff with a group petting session.
* AscendedExtra: Actor example; Roger voiced dozens of minor and incidental characters prior to being added to the roster for good as Thomas.
* BerserkButton: He doesn't like to be called a mama's boy. Muscle Man learned that the hard way.
* BlankSlate: Given he has no specific character role yet, for some fans he tends to fall somewhere between this and TheEveryman.
* BrickJoke: 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.
* ButtMonkey: Mainly in "Starter Pack" and the Christmas Special.
* ChickMagnet: 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. [[spoiler: "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.
* TheDogBitesBack: In "Exit 9B" [[spoiler: 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.]]
* TheDragAlong: 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.
* GoingCommando: Decides to do so to avoid getting wedgie'd by Muscle Man again.
* GreenRooming: 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", [[spoiler:although a good chunk of that time is spent frozen.]]
* InitiationCeremony: Mercilessly pranked as part of his hazing in the episode after he is introduced, by Muscle Man in particular. [[spoiler: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.]]
* TheIntern: Thomas is interning at the park as part of his college course.
* NaiveNewcomer
* OnlySaneMan: Only guy who routinely questions the bizarre antics the park crew get into.
* PettingZooPeople: A literal example.
* PhraseCatcher: 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
* RidiculouslyAverageGuy: At least where he is the main character.
* SixthRanger
* StraightMan: To everyone that isn't Benson.
* TookALevelInBadass: Who knew Thomas was strong enough to [[spoiler:put Muscle Man in an armbar]] in ''Thomas Fights Back''? He also helps the group by [[spoiler:pulling off a [[TheChessmaster brilliant gambit]] as an undercover intern at the opposite park]].

[[folder:Other Characters]]
!Margaret Smith
!!!Voiced by: Janie Haddad
!!!Debuted in: Season 1, "Caffeinated Concert Tickets"

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

* AllGirlsWantBadBoys: 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 HeroicBSOD from seeing Pops naked).
** Eventually inverted around Season 3.
* BarefootCartoonAnimal: In most episodes, though in some she does wear shoes.
* BareYourMidriff: Has her moments.
* BlackComedy: If her story in "Terror Tales of the Park II" is any indication, she's got a messed up sense of humor.
* BrainlessBeauty: Had tendencies of this in early seasons, but has [[CharacterDevelopment developed]] to be a little smarter and more reasonable. And she ''did'' get into college. So there's some modicum of smartness up there.
* CharacterizationMarchesOn: Margaret was a FlatCharacter 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).
* DaddysGirl: 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''.
* DamselInDistress: In the Cartoon Network RS game, ''Fist Punch''.
* DistaffCounterpart: To Mordecai. They were quite clearly designed to complement each other.
* FeatherFingers
* GenderEqualsBreed: Her mother is a robin, like herself and her father is a ''human.''
* GenreSavvy: In "Picking up Margaret" Margaret is hesitant to trust that Mordecai just wants to give her a ride and isn't being betted or in some other way forced to, then she wants to make sure nothing crazy is going to happen.
* InterspeciesRomance: 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.
** Considering [[spoiler:her mom married a human, it seems to be a trait she picked up from her]].
* LethalChef: 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.
* MsFanservice: She tends to dress rather provocatively.
** In "Slam Dunk" we get a [[MaleGaze close up of her butt]], [[GettingCrapPastTheRadar seriously.]]
--->[[ Hey Mordecai!]]
* MyGirlIsASlut: 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".
* [[NiceGuy Nice Girl]]: She's really friendly [[BewareTheNiceOnes most of the time.]]
* NightmareFetishist: 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.
* NonMammalMammaries: "Lady pecs", in Mordecai's words. She even gets to show a little {{sideboob}} in the concert episode, and cleavage in others.
* PettingZooPeople
* PinkGirlBlueBoy: Pink Girl to Mordecai's Blue Boy. Technically, she's bright red, but it looks pink due to color saturation.
* PutOnABus: In the season 4 finale, after she was accepted in her dream college.
* SatelliteLoveInterest: 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.
* SeashellBra: During Mordecai's dream sequence in the episode "Meat Your Maker", he envisions Margaret wearing one that just [[GettingCrapPastTheRadar ''barely'']] covers her [[UnusualEuphemism lady pecs]].
* OfficialCouple: With Mordecai as of ''Meteor Moves'', but the relationship didn't last too long, once she got accepted into college.
* TheSmurfettePrinciple: In the entire first season, she was in only ''three'' 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.
* ToothyBird
* WhatDoesSheSeeInHim: 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 "[[CatchPhrase OOOOOOOOH!]]")''
** This extends even to Mordecai, because even though he's a NiceGuy, 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.

* ActionSurvivor: 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...
* {{Adorkable}}: Good lord is she ever.
* AuthorAvatar: 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.
* BlindWithoutEm: After hearing that [[spoiler: Rigby thinks she's hot [[TheGlassesGottaGo without her glasses on]]]], she tries to serve coffee without them and bumps into a table.
* BrainyBrunette: Including straight A's in school.
* CharacterizationMarchesOn: Her Cloudcuckoolander tendencies are played up far more in "Do Me a Solid" than they are in later episodes.

** 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.
* ADayInTheLimelight: "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" [[spoiler: Her first major role following Margaret's departure]]. She gets her first full example of this in "Video 101".
* HiddenDepths: Proves to be an adpet trainer in "One Pull Up"
* {{Meganekko}}: An anthropomorphic one.
* OneBookAuthor: 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.
* SatelliteCharacter: Suffers from the same affliction as High Five Ghost, serving mostly as a side dish that comes along with Margaret. She never gets much screen time to herself.
** At least until "One Pull-up", where she gets a considerable amount of screentime, with Margaret not appearing once.
** Subverted [[spoiler:permanently]] after [[spoiler: Margaret leaves for college. ]]
* SheCleansUpNicely: In "Access Denied".
* ShipperOnDeck: 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.
* ShrinkingViolet: Has shades of this.
* SkintoneSclerae
** In later episodes Eileen seems to go through a redesign. She loses this and her pigtail is done up on the other side.
*** [[spoiler: She still has this trope with her glasses off.]]
* StalkerWithACrush: 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.
* WhatDoesSheSeeInHim: With the way Rigby acts towards her, you'd think she'd try someone else...
** [[spoiler:He warms up during "Camping Can Be Cool" - he thinks Eileen starting a fire without matches [[YourApprovalFillsMeWithShame and throwing a rock through Margaret's car door]] is pretty awesome.]]
** This is subverted as of later episodes, with Rigby treating her nice and even showing hints of being attracted to her.

* VisualPun: He's a sour lollipop.
