[[folder: Antagonists]]

! The Greasers
-> Voiced by: Creator/TomKenny (Cliff), Maria Bamford (Shriek), Creator/CarlosAlazraqui (Lube)
* [[spoiler: BolivianArmyEnding]]: They're last seen [[spoiler: getting eaten by a giant sea monster. The reason it's this and not [[KilledOffForReal a certain other trope]] is because Cat, Dog and their parents all survived the same fate, so it's possible that the Greasers would get out too ([[SeriesFinale not that it really matters]])]].
* BrattyHalfPint: Shriek
* EmbarrassingFirstName: Cliff's name is short for Clifford, which he isn't proud of. Shortly after, it's revealed that Lube's name is Ignatius.
* FantasticRacism: They really hate cats. Crosses over with AnimalJingoism because they're dogs.
* FatBastard: Cliff
* GangOfBullies
* HiddenDepths: All three of them have these. Cliff is very much [[RealMenWearPink in touch with his feminine side]], Shriek has a crush on Dog and is SecretlyWealthy and Lube is a skilled mechanic.
* [[{{Jerkass}} Jerks]]
* MeaningfulName: Shriek. She shrieks. Boy does she ''[[CuteButCacophonic shriek]]''
* [[LikeFatherLikeSon Like Parents Like Son]]: Lube's parents are shown in the finale, and they're just as dumb as he is.
* RealMenWearPink: Cliff [[spoiler: takes ballet]]. He's not only really good at it, but he's also really ''proud'' of it.
* SecretlyWealthy: Shriek. [[RebelliousPrincess She really hates it, though]].
* SpoiledBrat
* TerribleTrio
* TokenGoodTeammate: Lube is not only the nicest Greaser, he's probably the nicest character in ''the entire show''.
* TrueCompanions: [[DependingOnTheWriter Several episodes]] show them to be this. They may be rather nasty bullies, but they stick together.
* VillainousCrush: Shriek has a crush on Dog. Strangely enough, ''Cat'' seems to be attracted to her.

! Rancid Rabbit
-> Voiced by: Creator/BillyWest
* BigBad: Nearly every episode he's in has him as the main antagonist.
* CatchPhrase: "Leaping lumbago!"
* CorruptCorporateExecutive: It's implied that he actually ''owns Nearburg''.
* TheDitz: Sometimes.
* EvenEvilHasStandards[=/=][[PetTheDog Pet the CatDog]]: Seeing [=CatDog=] swarmed with psychotic fleas and the flea belt no longer being enough to help them is enough to convince him to give them a flea bath with no apparent ulterior motive.
* FatBastard
* {{Jerkass}}
* WhyDoYouKeepChangingJobs: Subverted. He doesn't change jobs, he has ''all the jobs''.

! Eddie the Squirrel
-> Voiced by: Dwight Schultz
* BrattyHalfPint
* HarmlessVillain
** NotSoHarmless: He almost killed Lube with a tick at one point and built a giant robotic cat to get revenge on the Greasers and enslave the town.
* IneffectualSympatheticVillain: Heavy on the ineffectual, light on the sympathetic.
* InformedSpecies: He's supposed to be a squirrel?
* MotorMouth: Nobody can shut the little twerp up.
* '''SmallAnnoyingCreature'''
