Since its initial inception in 1997,South Parkhas been pitting four crudely animated boys and their small Colorado town against the weirdest, the wildest, and the most warped catastrophes the modern world has to offer. With a mix of satire and dark humor, creators Trey Parker and Matt Stone have used their penchant for creating and voicing silly characters as a base from which to build one of the most iconic cartoon shows of all time.

While the main cast of goofy characters has largely stayed the same through the show’s over 300 episodes, the side characters and one-offs have given fans exposure to countless celebrity parodies and satirical personalities.
Updated August 07, 2025, by John Charron:Considered by many to be one of the finest examples of satire, South Park is still a resounding success even after decades of laughs. As many die-hard fans will tell you, the characters are the ones who make the show special. Sometimes, it isn’t even the main or recurring characters that make the episode memorable, but rather the one-off goofball that rakes in the chuckles. It’s easy to see that series creators Trey Parker and Matt Stone love using these atypical characters to bring home the jokes. A few one-off characters have become regulars over the years, but the ones that remain in their solitary episode are still just as special.
15Trent Boyett
The boys ofSouth Parkare no strangers to making enemies, but the one that seems to scare them the most is Trent Boyett. After a preschool prank went wrong, the boys blamed it on Trent Boyett, and he was taken away and thrown into juvie.
All goes well until he is released from his confinement and immediately begins hunting down the four boys who wronged him.The whole episode is crazy, but Trent’s tough prison mindset is a funny contrast to the other school kids.
14Keyshawn
Keyshawn the pimp is the star of another classicSouth Parkepisode from the show’s thirteenth season. After Butters inadvertently becomes a pimp, he finds that he needs some advice on how to properly do his new job.
Butters meets up with a real pimp named Keyshawn who teaches the young and naive Butters how to make some real money. Even better is when Keyshawn falls in love with an undercover cop and marries him. Keyshawn could easily have been in more than one episode, though does make an appearance inSouth Park: The Fractured But Whole.
13Baby Fark McGeezax
With a name like that it has to beSouth Park. In the pinewood derby episode, Randy steals a superconductor magnet to use for Stan’s Boy Scouts pinewood derby race, accidentally sending the car into warp speed and ultimately outer space.
Enter Baby Fark McGeezax, an alien bank robber carrying stolen loot. Baby Fark is hysterical, as a composite of old 1930s gangsters, he talks like a silly movie villain,but he is obviously an alien. In reality, Baby Fark is just testing the Earthlings to see if they are deserving to join the intergalactic community, which, of course, Randy ruins.
12Tad
An 80s stereotype in the flesh, Tad is the jerk-wad skier who can’t seem to help but fall into the cliché role of an 80s bully. The whole Aspen episode is a satire of the cheesy 80s movies in which the newbie skier has to take on the king of the mountain to get the girl and save the day.
Awful stuff, but Tad is goofy nonetheless. As, in accordance withfilm trope rules, he loses the big race, but he’s still a great one-episode character and is responsible for some of the episode’s very best moments.
11The Goo Man
An obvious parody of Daniel Plainview fromThere Will Be Blood, The Goo Man is a freaky, but funny “goo salesman.”The Goo Man has but one purpose in his one episode, to sell edible goo. A satirical spin on processed food and meat substitutes, The Goo Man is easily the selling point of the episode.
Every time The Goo Man is on-screen, he gives the other characters the heebie-jeebies. His stern voice, yet silly mission, make him one of the more memorable one-offSouth Parkcharacters in recent memory.
10Charles Manson
Charles Manson isn’t particularly well known for his Christmas spirit, but he is familiar with his dedication to family.South Parkuses Manson’s terrifying image as a cult leader in parallel with the cute holiday fun of aChristmas specialin the classic season two episode, “Merry Christmas, Charlie Manson.”
After Cartman’s uncle breaks out of prison with Manson, the boys find themselves spending the holiday season with the maniac, but, through a little Christmas magic, it becomes clear that even the most deranged psychopaths can find friendship and redemption.
9Internet Video Celebrities
South Parkhas always done a great job at staying relevant with the times. When the boys try to make “internet money” by creating a popular video trend in the essentialone-offepisode, “Canada on Strike,” they find themselves among other earlyinternet memelegends also looking for a payout.
From the Chocolate Rain singer to theStar WarsLightsaber Kid, the internet’s first memes come together in a tiny room for their hard-earned cash. Naturally, things get violent when their internet fame becomes a matter of competition, but, for fans of the show, the inclusion of these memecharactersis unforgettable.
8Cesar Millan
In the brilliant season ten episode, “Tsst,” Cartman’s bad behavior is put to the test through a series of intense television nannies, all of whom end up losing their minds.

The only match for Cartman’s wickedness isDog Whisperer,Cesar Millan, who immediately starts treating the lovable brat like a dog in thisunexpected cameo. Somehow, this technique works, and the rest of Millan’s tactics are downright hilarious as Cartman undergoes an emotional change from bad to good.
7A.W.E.S.O.M. - O 4000
A hilarious Cartman alter-ego, A.W.E.S.O.M. - O 4000 is thepoorly designed robot costumethat Cartman wears on a trip to L.A. with Butters in an effort to retrieve an embarrassing video of himself.
The distance Cartman is willing to go pretending to be a robotcharacteris extremely funny as is Butters' inability to recognize the blatant disguise. Things get hairy for Cartman when his robot antics cross paths with Hollywood and the military as they attempt to use A.W.E.S.O.M. - O for their own purposes.
6Mark Zuckerberg
Celebrities and famous figures are not strangers to theSouth Parkuniverse, yet some cameos are much odder than others. Facebook founder and CEO, Mark Zuckerberg, finally made it onto the show in season 21 in the episode, “Franchise Prequel.”
Portrayed as a bizarre villain who helps Butter’s alter ego, Professor Chaos, spread fake news about the “Coon and Friends” superhero group, Zuckerberg is badly dubbed, uses imaginary mind powers, and continuously talks about blocking people. A perfectone-episodecharacter to have in thissuperhero movie parody.
