History Characters / RegularShowAntagonists

* WhatExactlyIsHisJobAnyway: While Alpha Dog, Blitz Comet and Demel-Ishun are the rappers, and V-Tron plays the tracks, it's not clear what Francois does other than stand around and look tough.

* TheWonka: An eccentric, in your face Tv personality who apparently has reality-bending powers.

* BackFromTheDead: [[spoiler:They are among the villains revived in "Exit 9b".]]

* AffablyEvil: Outside of his attempts to impersonate, Doug is a legitimately hard-working and nice guy, even as he's arrested he simply gives Rigby a piece of his mind by pointing out how much he has to be thankful for.

* WhatHappenedToTheMouse: While Demel-Ishun gets injured after being crushed, Blitz Comet gets flown away and Alpha Dog is presumably obliterated, we don't see what happens to V-Tron and Francois

* UncertainDoom: Once the park workers escape the moon, the Moon Monster is left at the moon with no explanation as to what happened to it.

* {{Expy}}: Quite possibly of [[Franchise/TheIncredibles Syndrome]], since Ross is also an unrecognized genius who became a high-tech supervillain over rage at the protagonist for a perceived slight, has killed many heroes, and is causing destruction on a massive scale for the sake of his ego. He also has a childish sense of humor despite being played mostly serious, has grown [[VillainousWidowsPeak his hair into a wild spike]], and in the end is undone by a part of his own outfit. Coincidentally, both their [=VAs=] [[Creator/JasonLee have the same]] [[Creator/JasonMantzoukas first name]].

[[folder:Frank Jones]]
!!! Voiced by: John Cygan
!!!Debuted in: Season 4, "Trailer Trashed"

A health inspector who seeks to condemn Muscle Man's trailer so he can take it for himself.

* KickTheDog: Played straight initially as Frank not only threatens to send Muscle Man's trailer to the dump and get it scrapped, but when he gives him and his friends a whole day to spruce the trailer, Franks starts to destroy parts of Muscle Man's trailer, from the windows to his door. Subverted, however, as Muscle Man eventually stands up to Frank by [[TheDogBitesBack decking him in the face]].
* SoreLoser: Frank was the runner-up in the hotdog eating contest Muscle Man won his trailer from. He accuses Muscle Man of cheating back then by mushing his hot dogs together with water and that the trailer should've been his, only for Muscle Man to retort that it was totally a fair move and that the Japanese do it all the time.
* VillainHasAPoint: While Frank is obsessed with getting his hands on Muscle Man's trailer, he wasn't completely lying about it being in poor condition.

* BadPeopleUseAnimals: They harvest baby turtles and use them to achieve eternal youth, apparently sucking their own youth away in the process. There's also a group that do push-ups ''on'' the turtles.

!!!Voiced by John Cygan
!!!Debuted in: Season 5, "Silver Dude"
[[quoteright:386:https://static.tvtropes.org/pmwiki/pub/images/the_silver_man.png]]
A street performer who uses his boombox to steal Mordecai and Rigby's act.

* EnemyMime: [[spoiler: Gets turned into a mime when being sent to street jail.]]
* {{Greed}}: He steals Mordecai and Rigby's songs because he wants all the money from their act all for himself.
* {{Jerkass}}: He copies other peoples' acts, while claiming that he's not ripping them off. And he doesn't care at all.
* LaserGuidedKarma: [[spoiler: When he gets angry and tries to take the money during a street performing battle, he gets sent to Street Jail.]]
* PlagiarismInFiction: Mordecai and Rigby are clearly not pleased with them recording their raps and taking all the credit. In fact his whole act is just him playing what they said on his boombox while doing a basic ball trick.
* SoreLoser: He tries to steal the winnings when his act starts to fail.
* YoureNothingWithoutYourPhlebotinum: He uses his boombox to copy their act; but when his boombox gets destroyed, he tries to rap on his own only to fail miserably.

[[folder:Bert Coleman]]
!!!Voiced by Creator/TroyBaker
!!!Debuted in: Season 5, "Expert or Liar"
[[quoteright:190:https://static.tvtropes.org/pmwiki/pub/images/bert_coleman_5.jpg]]
[[caption-width-right:190:Are you an expert...Or LIAR?!?]]

The eccentric and mean-spirited host of "Expert Or Liar", a gameshow that makes people answer certain questions or be humiliated on national television.

* HateSink: Even by this series' standards, he's so in-your-face odious you'll feel like cheering when Rigby punches him out.
* {{Hypocrite}}: He loves exposing his contestants as "liars", while disguising himself and tricking them onto his show in a very dishonest way.
* {{Jerkass}}: Coleman gets his thrills from humiliating people with questions very few people would know and seems to actively ''want'' them to fail at his contests.
* InexplicablyAwesome: He seems like a normal man at first, but then he shows the ability to warp people to other dimensions based on the subject of his trivia. Given the presence of beings with similar powers, he might be just another otherworldly entity.
* JerkassHasAPoint: He seeks out people who claim to be "experts" and tells them how wrong they are if they don't live up to their claims. Though he's just a huge jerk about it and humiliates them on worldwide television for no other reason just to see them embarrassed.
* MasterOfDisguise: He approaches contestants disguised as random people with lifelike costumes. Rigby spends a lot of time trying to root him out. Then again, he might just have the budget for that kind of disguise.
* NoIndoorVoice: Being a gameshow host, he usually proclaims things loud and obnoxiously.
* RealityWarper: When Rigby approaches him for a rematch, Bert sends them to a video-game based dimension where Rigby must answer each question to overcome obstacles. It's not clear if Coleman actually did this or it's just a metaphorical image, but given the nature of this show, it wouldn't be surprising.
* SlasherSmile: He has an almost constant one.
* UnsportsmanlikeGloating: Coleman is ''not'' a gracious host. The reason Rigby wants a rematch is because Bert was just that much of a dick to him for getting a question wrong.
-->Flower expert!? More like A BIG DUMB LIAR NO-ONE WANTS TO HANG AROUND WITH!
* VillainyFreeVillain: He isn't really evil, just a particularly rude game-show host, but he's such a smug, insufferable jackass you're still rooting for Rigby to take him down.
* TheWonka: An eccentric, in your face Tv personality who apparently has reality-bending powers.
