How to watch

Invader Zim follows an incompetent alien soldier from the Irken Empire who is sent to Earth on a fake mission to get him out of the way. With his malfunctioning robot GIR, Zim plots to conquer humanity while being thwarted by Dib, a paranormal-obsessed kid whom nobody believes. Richard Steven Horvitz voices Zim, Rosearik Rikki Simons voices GIR and Andy Berman voices Dib.

🕐 Release Order

Here is the franchise in the order it premiered.

1. Invader Zim Season 1 (2001)
2. Invader Zim Season 2 (2002)
3. Invader Zim: Enter the Florpus (2019)

Nickelodeon canceled the show during Season 2, leaving several finished episodes unaired in the US until they premiered on Nicktoons in 2006. More than a decade later, Netflix released a feature-length revival.

📖 Story Chronology

Story order matches release order. Enter the Florpus picks up years after the series ends, as Zim emerges from his base to restart his plans.

1. Invader Zim Season 1 (2001)
2. Invader Zim Season 2 (2002) — including episodes first aired in 2006
3. Invader Zim: Enter the Florpus (2019)

Which Order Should You Choose?

Watch both seasons first, then finish with Enter the Florpus. The show is mostly episodic, so you won't get lost if you skip around, but the movie is packed with callbacks to the series and rewards fans who know the characters. The original series ends without a proper finale, so the movie is the closest thing to a conclusion — and a great excuse to revisit one of the strangest cartoons Nickelodeon ever aired.
