Invader Zim made its debut with Nickelodeon back in 2001, and introduced fans to a wild new space world. The franchise was led by the titular Zim, who had come to Earth with the hopes of conquering the planet. Despite the fact that his overseers didn’t expect much from him and had wanted to just get rid of Zim entirely, Zim tried his best to take down humanity with all kinds of wacky machines and experiments. It’s through all of this we found out about a whole new universe too.
Invader Zim Kicked Off a New Sci-Fi World

Originally created by Johnny the Homicidal Maniac creator Jhonen Vasquez, Invader Zim was a rather surprising series released with Nickelodeon at the time. While the network has had edgier cartoons beforehand like with The Ren & Stimpy Show, Invader Zim immediately felt different. Vasquez clearly inject Invader Zim with all of the creepy and kooky qualities that the creator was known for, and it resulted in an animated series that blended together different sci-fi, horror and comedic elements to create something brand new altogether. It was unlike anything seen on the network before or after really.
Invader Zim introduced fans to the titular Zim (Richard Steven Horvitz), an alien from the Irken Empire on the Planet Irk. This empire’s main goal is to spread throughout space and conquer planets, but hilariously have a hierarchy based on how tall they are. Even Zim’s overseers are called “The Almighty Tallest,” and are only in charge because they happen to be taller than the rest of the series. It’s already a fun set up for an alien species, but then it’s taken even further with Zim as it’s revealed that he’s very low on the totem pole.
Zim was already seen as a failure by the rest of the empire as he almost destroyed it in a previous invasion, so the Tallest decide to send him to a faraway planet under the guise of a special mission. This planet turns out to be a dystopian version of Earth that has been ruined by tons of mindless consumerism and capitalism that Zim sort of flounders his way towards trying to conquer with his alien devices and schemes. And as fans might have realized, it led to a ton of shenanigans over the course of its two season run with Nickelodeon.
