WARNING: The following article contains spoilers for Invader Zim: Enter the Florpus, streaming now on Netflix.

Invader Zim: Enter the Florpus reintroduces audiences to the world of Invader Zim, bringing back most of the classic cast for a massive new adventure. By the end of the film, Earth has been (barely) saved from the reality-altering effects of the Florpus by the Membrane family. However, the Netflix special makes sure to leave the door open for multiple characters to move forward within the universe. There are even a number of plot threads set up by the film any potential follow-ups could explore.

Here are all the ways Enter the Florpus sets up the future of Invader Zim.

Zim

The titular alien invader has failed to capture Earth for the Irken Empire again and again. But Enter the Florpus sees Zim get closer to his goal than ever before. Not only is he able to trick humanity into backing his plans, but he's also even able to teleport the Earth itself directly to the rest of his race's armada. But the last-minute unity from the Membrane family finds a way to rally and save humanity. Earth is teleported back to its normal place in the universe, and Zim's robotic armies are defeated.

However, the film doesn't end with Zim captured or even paying for his crimes. Instead, Zim is still free and bugging Dib. This suggests that Zim's self-imposed period of waiting is officially over. Even if this plan didn't work, Zim is too stubborn to give up on taking over the world. It appears that Zim is officially back to target the planet and that Dib will once again have to become the main line of defense against Zim and his schemes. Seeing how this was the core of the original series, it's not hard to imagine this set-up allowing for a full-blown Invader Zim return.

The Membrane Family

The Membrane Family ends the film closer than ever. Dib and Gaz have found a rhythm working together, although Gaz's animosity for her brother is still present. Professor Membrane has proven to Dib that he does care about him, even if he's convinced himself that all the alien interactions he just experienced were hallucinations. The family has even (reluctantly) accepted Clembrane, the failed clone Zim made of Membrane, as a member of the family.

But the Membranes still escaped from a high-security space prison via destroying a wall and blasting off into space. That's the sort of thing that would turn someone into a fugitive on a galactic level. There's a chance to people who run the prison might decide to make an example of the Membrane family, and could come to Earth to take them back to jail. This could be what finally reveals to Membrane once and for all that alien life is real... or he could just continue to think they're hallucinations while he blasts them with his laser cannon robot arms.

The Almighty Tallest

The lords of the Irken Empire, the Almighty Tallest have always hated Zim. Zim's antics have led to unparalleled destruction around the galaxy. This is what got Zim assigned to such a backwater planet like Earth in the first place. They'd even casually come to love the belief that Zim was dead. But upon discovering his survival, they both grew furious. It only got worse when Zim teleported Earth right into the line of sight for the armada. This led to the Tallest priming every weapon they had and targeting Earth: they're ready to destroy the world if it means Zim dies too.

Fortunately, Membrane figures out how to teleport Earth away, just in time to escape both the Florpus and the wrath of the Almighty Tallest. Unfortunately for the Irkens, this left them heading straight into the reality-bending Florpus instead. The last we see of them, they're screaming in terror and being morphed by the Florpus as Zim tries to call them. The energies of the Florpus were enough to rip a planet apart, so it's possible that the Irken armada wouldn't be able to survive extended exposure to the Florpus. If they do escape, they could decide to come after Zim (and the Earth) as revenge. But if they don't, it could leave a power vacuum that other Irkens (like Zim's rival Tak) could try to take advantage of.

Tak's Spaceship

Taken from Tak, the other Irken invader who tried to conquer Earth in the original series, Tak's spaceship has quietly played major roles in previous Invader Zim episodes. But the ship's return in Enter the Florpus proves crucial to the Membrane family's victory over Zim. The ship gives Dib and Gaz the chance to save their father from space prison, as well as the ability to return to Earth to try and stop Zim.

Gaz ends up actually seeming to bond with the ship. Her video game skills have always made her uniquely talented to use Irken technology, so Gaz is able to use fly the ship to great effect over the course of the film. But upon returning to Earth, the ship is severely damaged while flying through an asteroid field, leaving it broken once more. However, Dib was able to repair the ship in the past, so there's no reason he wouldn't be able to do so again. On top of that, the friendship that builds up between Gaz and the ship's AI could give her plenty of incentive to repair the ship herself. This would give Gaz more reason to be involved in any future plots that threaten the world.

Directed by Jhonen Vasquez and Jake Wyatt, Invader Zim: Enter the Florpus stars Richard Horvitz, Rikki Simons, Andy Berman, Melissa Fahn, Wally Wingert, Kevin McDonald, Rodger Bumpass and Olivia d'Abo.
