!Main Characters

!!Ren Hoek
[[caption-width-right:250:Not Ren's natural state, but fitting nonetheless.]]
->Voiced by: Creator/JohnKricfalusi (seasons 1-2, ''Adult Party Cartoon''), Creator/BillyWest (a few episodes in season 2; seasons 3-5)

->''"They think Iím crazy. But I know better. It is not I who am crazy - it is I who am MAD!"''

An asthmatic Chihuahua prone to psychotic breakdowns and acts of violence. Whatever he does, expect for it to be somehow materially motivated.

* AdaptationalVillainy: He was hardly a nice guy in the original show, but ''Adult Party Cartoon'' ramps up his worst qualities while reducing or outright excising his good ones.
* AllMenArePerverts: Just watch "Naked Beach Frenzy" and you'll know what we mean.
* AmbiguouslyGay: WordOfGod says Ren likes human women, but "when you look like Ren, you take what you can get".
* AntiRoleModel: Stimpy thinks otherwise, though.
* '''AxCrazy'''
* CatchPhrase: "YOU EEDIOT!"
** "Five bucks!"
** "WHAT ''EEEZ'' IT, MAN?!"
* ChewToy: In the original series, though he deserves most of it, given his jerky nature.
* CivilizedAnimal
* CollectorOfTheStrange: Opera records, uncurable diseases, dinosaur droppings, and celebrity wigs. Glass coffee tables in "Ren Needs Help".
* ComedicSociopathy
* CryCute
* DeadpanSnarker: Sometimes. "What's so secret about ''that'' spot?"
* DepravedBisexual: He has sex with Stimpy and feels attracted to women, while he's not the most stable person to be around.
* DogsAreDumb: Averted. Ren is rather intelligent and most definitely very cunning.
* EnfantTerrible: It is shown in "Ren Seeks Help" that he enjoyed torturing and mutilating animals as a child.
* FacePalm: Does this frequently. Best example is in "To Salve And Salve Not" when he does the after going insane for about five seconds and his face cracking and turning blue.
* FreakOut: Extremely prone to them, as he's both neurotic and psychopathic. Surprisingly for a cartoon, however, his freak outs tend to be very realistic.
* FreudianExcuse: He explains his tendency to be violent with "the first sensation I felt in my life was [[MinorInjuryOverreaction unspeakable pain]]. From then on, I wanted to inflict the pain on others!". [[DisproportionateRetribution He was referring to a doctor who slapped him on the buttocks right after the carriage.]]
** That and the lye.
** It is also implied that his life growing up was anything but sane; one scene shows Ren's father intending to give Ren a pistol to kill a frog with, but his mother quickly intervenes....and passes Ren a [[ChainsawGood chainsaw]] instead.
* FunnySchizophrenia: "Hermit Ren". His SanitySlippage was extremely disturbing and borderline creepy, every second of it, [[BlackComedy but it was]] PlayedForLaughs.
* GeniusBruiser
* HairTriggerTemper
* TheHedonist
* TheHermit: [[ExactlyWhatItSaysOnTheTin "Hermit Ren"]].
* HeterosexualLifePartners: WordOfGod confirmed that the "heterosexual" part varies depending on [[RuleOfFunny what is funnier]] for a specific episode.
* HumanlikeFootAnatomy
* Hypocrite: It's jarring to see Ren smack Kowalski for smoking in "Fake Dad", telling him that smoking is unhealthy... but in many episodes of "Red and Stimpy Adult Party Cartoon" we see Ren smoke constantly.
* IAmNotWeasel: He was mistaken for a number of other animals, like a rat, cat and even a mosquito.
* IJustWantToBeLoved: Says this word for word in 'Stimpy's Fan Club'.
* InferioritySuperiorityComplex: And how.
* InsaneEqualsViolent: Sort of averted here. Ren is both insane and violent, but almost never at the same time. It's very scarce for him to perform acts of violence when he's having his psychotic {{Freak Out}}s. ToThePain monologues, on the other hand...
* IntelligenceEqualsIsolation: Something he complains about in "Sven Hoek" and "Stimpy's Fan Club". Also, Stimpy seems to be his only friend ''and'' admirer.
* IronButtMonkey:Even moreso than Stimpy, but he usually brings it on himself.
* ItsAllAboutMe: Ren is frequently selfish and inconsiderate (when not outright abusive) to Stimpy. This was a more nuanced vice in the Spumco made episodes, though took over his personality in many Games episodes.
* {{Jerkass}}
** JerkWithAHeartOfGold: In the original series. More of a JerkWithAHeartOfJerk in the Games episodes ([[CharacterCheck with the odd exception]]), but returns to his old personality in some episodes of Adult Party Cartoon!
* KickTheMoralityPet
* LackOfEmpathy
* LargeHam
* LaughingMad: Frequently - Creator/JohnKricfalusi admitted Creator/BillyWest did the most extreme laughs, seeing as John isn't a professional voice actor and was unable to laugh madly enough.
* LeanAndMean
* ManHug: Not very manly in some instances, like "Stimpy's Fan Club".
* TheMentallyDisturbed
* TheNapoleon
* NoCelebritiesWereHarmed: Ren is one of a long line of cartoon characters who have a voice based on PeterLorre.
* NoIndoorVoice
* NoRespectGuy
* OddCouple
* OddFriendship: One has to wonder how they became best friends in the first place. Stimpy is a KindheartedSimpleton whereas Ren is an AxCrazy {{Jerkass}}.
* OlderThanTheyLook: Pursuant to "I Was a Teenage Stimpy", he is much older than his best friend, maybe even around 60 years old in human age.
* OohMeAccentsSlipping: Billy West's voicing for Ren had a very erratic dialect to say the least. Kricfalusi had some moments too, but far more subtle.
* PlayedForLaughs: '''Averted''' in most cases of his epic [[FreakOut freak outs]]. When pushed to his mental limit, Ren becomes genuinely terrifying and disturbing. Some of them are quite ''dark'' for an ostensibly [[WhatDoYouMeanItsNotForKids "kids cartoon"]]; it seems as though the aim of several of his freak outs weren't exactly to incite laughter from the audience, but for pure shock value. Take, for a good example, [[https://www.youtube.com/watch?v=dW3Roqmfr94 this scene]] where he very realistically descends into madness while contemplating murdering Stimpy.
* PsychopathicManchild
* SanitySlippage: Too many of them, but the most infamous examples are "Stimpy's Fanclub", "Space Madness" and "Hermit Ren".
** "Ren Needs Help" turns this UpToEleven.
* TheScrooge: He can have some greedy tendencies.
* {{Seme}}: In 'Adult Party Cartoon', he explicitly states himself as this.
* SensitiveGuyAndManlyMan: Manly Man to Stimpy's Sensitive Guy.
* ShorterMeansSmarter: this varies, of course, due to the {{Off Model}}ness of the show - sometimes, Ren would be Stimpy's height, others, he would be noticeably smaller.
* SmallNameBigEgo
* TheSociopath
** SociopathicHero
* StrawNihilist: Would have been revealed to be one in the unmade episode "Life Sucks". He spends the whole episode telling Stimpy about the horrors of humanity and hammering into him that life is meaningless, horrible and stupid.
* StrongFamilyResemblance: Averted with Sven. He has some typical canine traits, but in general resembles Stimpy much more than Ren, both in terms of appearance and personality.
** Ren's father would either resemble Ren physically, albeit taller (Ren Seeks Help), or look more like Sven (Hermit Ren).
*** His mother looks like him more.
* TalkingAnimal
* TookALevelInJerkass: In the Games episodes. One could argue he's no less sociopathic under Spumco's pen, but he lacks as many redeeming moments of genuine empathy or repentance ([[JerkWithAHeartOfJerk or reveals them to have a insincere or selfish ambition]]).
** According to Bill Wray, the series was actually pressured to make Ren meaner in the Games era (a complete contrast to the mandates of the Spumco seasons). Some accounts even suggest some softer moments for Ren were intended in episodes such as "Ren's Pecs" and "Sammy And Me", but were omitted to befit this mandate.
* TranquilFury: He can get so angry that he becomes [[DissonantSerenity eerily pleasant]], which is best shown at the end of [[http://www.youtube.com/watch?v=iR6KjNmN2BA Sven Hoek]].
* TrueCompanions: With Stimpy.
* {{Tsundere}}: Borderline type A.
* UnsympatheticComedyProtagonist
* VillainProtagonist: In The Games episodes and the occasional episodes of Adult Party Cartoon.
* VitriolicBestBuds: Type A with Stimpy.
* VocalEvolution: When Kricfalusi returned to voicing Ren in Adult Party Cartoon, his pitch was somewhat deeper and gravelier, with his resemblance to Peter Lorre being more blatant. Allegedly this was because Kricfalusi had trouble making his voice sound right via pitch shifting.
** Billy West underwent a similar evolution. His initial roles as Ren were more helium pitched. When decided he could reproduce the voice without pitch shifting, he continue the role in his natural voice. He also started to mimic Kricfalusi's version less, his accent becoming less pronounced and the tone more nasal and hammy.

!!Stimpson J. Cat
->Voiced by: Creator/BillyWest, Eric Bauza (''Adult Party Cartoon'')

->''"I'm hiding in the closet...like an idiot."''

Stimpy is an overweight manx cat[[note]]On the other hand, maybe his tail is very, very, VERY short. Then again, his not having a tail may just be the "you-know-what" of the gag of the moment. It's not really the point either way...except when it is. [[MST3KMantra It's just that kind of show]].[[/note]] with no...er, well, let's say "little" brains (though not as extremely little as, say, [[TheSimpsons Ralph Wiggum]]) and a big heart. Despite having to deal with Ren's [[AxCrazy insanity]] and violence, he manages to put up with ''everything''.[[note]]Then again, that may also be part of the gag, since being the "eediot" he is, he's implied to not even realize what kind of person Ren really is, though that typically changes between episodes...sometimes.[[/note]]

* {{Adorkable}}
* AmbiguouslyGay: Prominent in the original series (unlike Ren, he was never portrayed as attracted to any female character, though the very first episode showed Stimpy as a chick magnet when he became famous), obvious in ''Adult Party Cartoon''.
* AscendedFanboy: In 'Stimpy's Big Day', he wins a poem writing contest for the chance to meet Muddy Mudskipper, and becomes a big star in Hollywood, doing all sorts of TV shows and commercials, all despite Ren's "cartoons will ruin your mind" rants.
* BewareTheNiceOnes: He calls out on Ren and is extremely grumpy in "Son of Stimpy".[[note]]Then again, considering [[DeconstructiveParody what this episode]] [[DudeNotFunny is really all about]], it may not count...[[/note]]
** In "Terminal Stimpy", he manages to terrify Ren in a fit of rage.
* BigEater
* BreakTheCutie: A number of episodes, most notably "Son of Stimpy".[[note]]On the other hand, this was only done as part of John K.'s attempt to prove his point about "fake pathos".[[/note]]
* BumblingSidekick: So bumbling, that Ren would just ''love'' to [[LiteralMetaphor "kick" Stimpy]] [[IncrediblyLamePun to the "side"]], but, as stated on the "You Eediot" music album...
-->"He's better, than no one."
* ButtMonkey: Very much, but not to Ren's extent.
* TheCaretaker:
* CatchPhrase: "Oh joy!"
* CatsAreMean: Subverted. Stimpy is a cat and possibly the nicest character on the show.[[note]]That, and as far as Ren is concerned, he's too stupid to be mean, anyway...[[/note]]
* {{Cephalothorax}}
* CharacterizationMarchesOn: In the pilot, Stimpy was more a slightly dopey prop for Ren to bounce off of, and barely had any speaking lines. The show quickly evolves Stimpy into an idealistic CloudCuckooLander who has almost as many limelight roles as Ren.
* {{Cloudcuckoolander}}
* CollectorOfTheStrange: His magic nose goblins.[[note]]"I picked them myself!"[[/note]]
* TheCutie: He is not very bright, but he has a heart of gold.[[note]]Ren would disagree about him being "cute", though.[[/note]]
* DumbIsGood[[note]]Except for when dumb is just...well, dumb.[[/note]]
* ExtremeDoormat: Comes with the territory of being an "eediot".
* FatBestFriend
* FatIdiot: Or as Ren would call him, a "fat bloated eediot".
* FatCat
* {{Gasshole}}
* GeniusDitz: Well, he thinks of and creates his own inventions. Some of which actually work, although their level of usefulness to humanity is unimpressive, making it more a subversion.
* HeavySleeper: Quite a few times. Ren would be awake at night and screaming, and not bothering Stimpy one single little bit!
* HeterosexualLifePartners: On Stimpy's side, however, this was highly debatable in the Nickelodeon days of the show, with many thinking that Stimpy was either asexual, [[BiTheWay bisexual]] with no proof, or just StraightGay. ''Adult Party Cartoon'' confirms the last implication.
* HumanlikeFootAnatomy: Subverted, except when it's not. He's usually toeless, but then again, how else would he know the feeling of [[{{Squick}} squishing kitty litter between them]]?...
* IAmNotWeasel: George Liquor has mistaken him for a dog, but didn't change his stance in this matter even after being corrected by Stimpy.
* InelegantBlubbering: He's quite a sight when sad or otherwise hurt. He'll either do this, or outright cry.
* InnocentBlueEyes: In various close-ups you can see that he has them.
* IronButtMonkey: A ''lot'' less than Ren.
* JerkassBall: Similar to Ren, while the Games seasons mostly remained loyal to his original KindheartedSimpleton persona, there are more frequent instances of Stimpy acting obnoxious, spoilt or high order InnocentlyInsensitive when the plot requires it.
* KindheartedSimpleton
* MadScientist: In his spare time, when he's not hanging around with Ren.
* ManChild
* MoralityChain: To Ren, to an extent - we can't be sure due to cases of DependingOnTheWriter.
* NiceGuy: Stimpy is friendly to everyone, even ''[[{{Jerkass}} Ren.]]''
* NoCelebritiesWereHarmed: His voice is based on [[Film/TheThreeStooges Larry Fine]] from ''The Three Stooges''.
* OddCouple: An understatement, but an example nonetheless.
* OddFriendship: One has to wonder how they became best friends in the first place. Stimpy is a KindheartedSimpleton whereas Ren is an AxCrazy {{Jerkass}}.
* ThePollyanna: Except for "Ren Seeks Help", when he finally loses it.
** A draft for ''In The Army'' did have him chewing out Ren for getting them into trouble multiple times, but it seemed out of character for him, so they changed it.
* ReedRichardsIsUseless: If Stimpy has the money and genius to make inventions like the Happy Helmet, why doesn't he sell some of them so that he and Ren won't have to keep changing jobs?
** [[FridgeHorror Because they could be used for evil]].
*** That, and he's...well, Stimpy.
* SensitiveGuyAndManlyMan: Sensitive Guy to Ren's Manly Man.
* SimpletonVoice: Modeled after another famous {{Cloudcuckoolander}}, [[Film/TheThreeStooges Larry Fine]].
* SpeciesSurname
* StupidGood
* TalkingAnimal
* {{Uke}}: In "Adult Party Cartoon", as explicitly stated by Ren.
* WhiteGloves: Don't ask why he has fingernails over them, though.
* VitriolicBestBuds: Type A with Ren.
* VolumetricMouth: Mainly when he cries.

!Other Recurring Characters

!!Mr. Horse
[[caption-width-right:202:A true RenaissanceMan.]]
->Voiced by: Creator/JohnKricfalusi (seasons 1-2,''Adult Party Cartoon''), Creator/BillyWest (seasons 3-5)

->''"No, sir. I don't like it."''

Mr. Horse is perhaps the OnlySaneMan. But he might be the AxCrazy one, too. He was a doctor, a psychologist, a psychically unbalanced creep, a war hero, a spokesman for the United Nations, an airplane pilot and many, many more. Who knows what he really is?

* CatchPhrase: "No sir, I don't / didn't like it."
* DeadpanSnarker
* NewJobAsThePlotDemands
* OnlySaneMan
* RenaissanceMan
* ThinkingTic: When asked what he thinks of something, he rubs his chin with his hoof and puckers his lips saying "Hmm...", before inevitably replying "No sir, I don't like it."
* WriterOnBoard

!!George Liquor, American
[[caption-width-right:250:George Liquor: American!]]
->Voiced by: Michael Pataki

->''"It's discipline that begets love!"''

George Liquor is an American so conservative, he thinks Republicans are communists. However, that part of his character was expanded in his own cartoon, ''The Goddamn George Liquor Program'' - in ''WesternAnimation/TheRenAndStimpyShow'', he's portrayed as a man with a strong faith in rules and discipline. He's only made 2 appearances on the show, due to the {{Nickelodeon}} execs' absolute condemnation for the character.

* AxCrazy
* {{Bowdlerize}}: His last name "Liquor" was censored with a RecordNeedleScratch SoundEffectBleep in original Nickelodeon airings of the show due to the alcohol reference (according to WordOfGod, Nick also interpreted the name as a play on "lick her").
* CatchPhrase: "What's this crap?!" and "HELLO! I'M GEORGE LIQUOR! AMERICAN!"
** "A smart-mouth, huh? A ''smart-mouth!''!"
* ChuckCunninghamSyndrome: He made only two appearances in the show (one of which was banned for a long duration of time), Nickelodeon allegedly hated the character and were willing to let Kricfalusi take the rights to Liquor with him following his departure. A third Liquor appearance was planned for Adult Party Cartoon but only made it to storyboard stages by the time of its cancellation.
* ComedicSociopath
* {{Eaglelander}}
* {{Jerkass}}: Probably unintentionally.
** He scares ''Ren'' at times.
* GoodIsNotNice: George firmly believes in discipline and rules, but takes them to an overzealous extreme.
* LargeHam
* LaserGuidedKarma: In "Man's Best Friend".
* LineOfSightName: Meta-example; in an interview with Wild Cartoon Kingdom #1, John K said that he instantly conceived the character upon seeing [[http://1.bp.blogspot.com/_XwGYOcz2ASU/RXJGGaNXBiI/AAAAAAAAAcE/LL_MiyiTWL4/s1600-h/wck1_pg38.jpg a sign for a (now long gone) liquor store]] in Van Nuys, California which was named George's Liquor (although the S had fallen off by the time John saw it).
* StepfordSmiler: Even when Ren was ''beating him up''.
* UnwittingInstigatorOfDoom: A strange example of a fictional character being one in real life. The episode with him getting brutally beaten up by Ren was one of the reasons for Creator/JohnKricfalusi's firing.

* KnightOfCerebus: Victor is known for being the most malicious and unpleasant character who has probably appeared on the show. And probably, he and his father are the only true antagonists in the show.
* PermaStubble: Victor's dad has this.
* {{Sadist}}: Both of them.
* SmokingIsCool

* SmokingIsCool
* TrademarkFavoriteFood: MEAT!

!!Wilbur Cobb

Voiced by Jack Carter

A former cartoon producer, first introduced in the episode "Stimpy's Cartoon", to whom the years have not been kind. He showed up in a few other shorts as a stock "rambling, crazy old man" character.

* {{Cloudcuckoolander}}
* {{Malaproper}}
* RamblingOldManMonologue: He's prone to this. In one episode, he's rambling to another old man who promptly dies. Cobb fails to notice and goes right on talking.

A small green ghost that spends his entire appearance trying to scare Ren and Stimpy and failing miserably. Only appears in the episode "Haunted House".

* BackFromTheDead: At the end of the episode.
