"EVERYTHING is funny. So long as you know it's a joke nothing is offensive. YOU try to protect people from wising up and getting beyond the idiotic shock and into a place where they can see how ridiculous things are. Do I think rape and abortion is funny? FUCK NO!! Jeezus! But Aborto and Rape-bo? HELL YES!"
— Jhonen Vasquez getting a bit preachy in Fillerbunny 3.
"Someone once said to me 'Jhonen, why do you make up so much shit on your Twitter?' and I just strangled the bastard with my tentacle arms."
Jhonen Vasquez is the creative force behind several comics, cartoons and other works, including Johnny the Homicidal Maniac, I Feel Sick, Squee, Fillerbunny, and others. He's widely known as the "Invader Zim Guy".Vasquez's characters are disturbed people living in a Crapsack World. A wildly hilarious one. His main characters include a violently schizophrenic serial killer, an unstable megalomaniacal extraterrestrial, an abused and terminally terrified child, and a tortured and suicidal bunny rabbit. Just to name a few. His jokes mostly involve very stupid people getting horribly maimed, tortured, yelled at, mocked and patronized. He's also quite fond of Doomy Dooms of Doom.Comics and cartoons include:
Also, this trope is basically half of GIR's personality.
Jhonen himself has frequently been described as a real life example of this.
The introduction to the "Meanwhiles" section of the Squee collection states that the express purpose of said comics was to keep him from getting bored with the main characters and their world.
Author Avatar: Assumed by many of his fans about comic strip artist Johnny C., despite Jhonen's statements to the contrary. Parodied by his "autobiographical" comic where he goes on an unbelievable adventure that, in humorously underwhelming ways, parallels one of Johnny's stories.
Notably: "I HAVE RATS IN MY ANUS". Nny's a bit of a hypocrite at times.
In I Feel Sick, after Devi quits her jobs and walks out, Jhonen makes a small cameo only to be told by Devi's ex-boss "I'm going to rape you up the butt and throw you out the window!" Cut to a scene of Devi exiting the building and a guy in the background falling out the window screaming "WHYYYYYY!?"
Butt Monkey: Fillerbunny, not to mention every single one of Johnny's victims.
Plus Dib, Squee, etc...
The Cameo: Fillerbunny once showed up in Invader Zim, as did an alternate-dimension version of Nny and various writers for the show. However, years before, Rob Hummel— Vasquez's main writing partner on the show— is depicted as a slimy department-store employee who is forced by aliens to mate with a chicken in one of the JtHM "Meanwhile" segments. Happy Noodle Boy also has a tendency to show up where he doesn't belong.
Not to mention said aliens become recurring characters of his. They show up several times in Squee & even have a major role in an episode of Zim (where they talk with inexplicable Liverpudlian accents).
Character Filibuster: Several of Jhonen's characters go on frustrated rants in the face of the crazy-ass world they live in, though their indignation is usually undercut by their own insanity/absurdity. Johnny C. and Dib are main offenders.
Transplant: Ms. Bitters appears in both Squee and Invader Zim. Since there's otherwise no indication one should consider the show a crossover, she might otherwise be considered an extremely blatant expy, or alternate dimension version of herself.
There are a few minor appearances by other comic characters in the show though. Tenna appears in one episode clubbing with GIR, and a 'demon' version of Nny can be seen on the Halloween episode, though that still is shaky ground to say they're all in a shared universe.
More solid evidence is the aliens from Zim episode "Abducted" being recurring players in Squee. The horned aliens that counter them in Squee #1 are also clearly precursors to the Vortian race that makes appearances on Zim.
