Jerkass / Futurama

Jerkasses in Futurama.

---

• Bender. In "A Pharaoh to Remember", Bender, Leela and Fry are trapped on an ancient Egyptian planet where Bender encourages the overseers to whip the slaves (which include Leela and Fry) more and work them harder. This goes on to where he starts ordering people worked to death to construct a monument to himself. Bender's callousness reaches such extremes at times it leads even the Robot Devil himself to be taken aback.
• Zapp Brannigan. He sends waves after waves of his men to their deaths, often sits back whilst doing so, and is a sexist perverted pig who has manipulated women into bed with him. He is also very cruel to his lieutenant Kif as he frequently treats Kif like a slave.
• The Professor himself agrees when Fry describes him as a "senile, amoral crackpot". He gleefully sends the crew to very dangerous missions (many of his previous employees died because of this). The Sting shows he's sent multiple crews on the same mission and each time they died.
• Hermes Conrad also counts. He is a huge bully towards Zoidberg as he often utters racist slurs towards him, deducts his paychecks for no reason, and hates him for reasons that he doesn't even bother to explain. Hermes also considered blowing the entire Planet Express Crew out of an airlock in one episode and after he decided to become a cyborg, went into deeper levels of jerkassery.
• Leo and Inez Wong. Not only are they greedy, and self-centered ranch/casino owners who frequently mistreat the native Martians who have to work for them. Not to mention their treatment of Amy, which only starts with them always being happy to remind her how tubby she used to be just to make her miserable. Leo himself is one of the villains for the movie "Into the wild Green Yonder" where he tries to wipe out 12% of the milky way for a miniature golf course.
• The head of Richard Nixon. He cheats in presidential elections, acts like a tyrannical dictator, has attempted to commit genocide on all the robots as a quick solution to global warming (the entities responsible for getting him elected the second time), and clamped an embargo on Omicron Persei 8 just because its ruler's son accidentally misfired a gun at a headless clone of Agnew.
• Ndnd is one towards her husband, Lrrr the ruler of Omicron Persei 8. All she basically does is nag and verbally abuse him all the time as in "Lrrencocilable Ndndifferences". She goes as far as to hit him over the head with a frying pan and kick him out of their palace house just because he botched an invasion on Earth and got her a gift consisting of a J.J Abrams face mask, and she even gets away with all of this without receiving any punishment whatsoever.
• The scammers from Bender's Big Score are Smug Snakes that unapologetically steal the personal info of everyone on Earth and send Bender (who is infected with an obedience virus) to kill Fry (who travels back to the year 2000) after they're done with abusing the time travel code on his ass (which they used to steal pretty much every important piece of art/architecture).
• Most of the kids at the orphanarium while Leela was growing up qualify, though Kirk qualifies the most. He mocks Leela for only having one eye in the most brutal fashion out of the bunch despite the fact that he's blind.
  Leela: How can you make fun of me, Kirk? You're blind!
  Kirk: My eyes may not work, but at least I have two of 'em! (laughs very loudly)
• Master Fnog from "Raging Bender" is a misogynistic douche who makes fun of Leela for trying to be a warrior instead of a housewife. He also stoops to cheating in a fake fight, which Leela calls him out on:
  Master Fnog: Better than being a girl! Like you! You're a girl! (laughs)
• Robot Santa. Due to a programming error, he invariably judges everyone (with the sole exception of Zoidberg) as naughty. Thus, he takes a sadistic delight in terrorizing everyone on Christmas night by destroying property, killing anyone he sees on the street, and abuses his toymaking Neptunians to the point that he doesn't even pay or feed them. It turns out that the person who was responsible for the programming error on Robot Santa was none other than Professor Farnsworth, who went back in time when the robot was created in a misguided attempt to correct his programming when in fact Robot Santa didn’t have any errors when he was first created.
