Invader Zim is an American animated television series created by Jhonen Vasquez that aired on Nickelodeon in the early 2000s. It followed Zim, an alien invader trying to conquer Earth while disguised as a human schoolchild, and became known for its dark humour, distinctive art style and loyal cult audience. Although its original run was short, the series lived on through reruns, comics and the 2019 film Invader Zim: Enter the Florpus. Short clips from the show are now widely shared online as nostalgic meme sounds.
