Nicktoons Unite! is an American animated action-adventure comedy crossover web television miniseries created for Netflix. It is a crossover of various Nickelodeon cartoons and is loosely based on the video game of the same name.


Upon accidentally discovering that the universe he inhabits is only one of many, Zim decides to conquer all of them. He puts together an army of nefarious villains so he can accomplish this. And if that's not enough, the constant travelling through dimensions is starting to affect other worlds by merging them together and transporting various characters away from their homes. Multiple familiar characters (i.e. TMNT, SpongeBob SquarePants, Lincoln Loud, Jenny Wakeman, Timmy Turner, etc.) are forced to come together for what will be the biggest adventure of their entire lives. Can they somehow restore order to their broken multiverse? Or could the threat be much bigger and badder than they first thought?
