The film 'Lilo and Stitch' deals with a lifeform genetically-engineered with the express purpose of destroying everything it touches falling to Earth and learning the value of love and family. Of all the Disney movies, it's exceptional for the incredibly dysfunctional main characters, and I've seen it more than once. However, I noticed something new and different this time: in typical movie style, the film ends happily, with the Grand Councilwoman of the Galactic Senate (or whatever) happy to allow Stitch to remain on Earth.
The end credits show Stitch teaching in a Hawaiian school about space-travel, and that both Lilo and Stitch get their own flying cars as Christmas presents. Aliens remain on the planet, and they are known about - the relationship overseen by the CIA's somewhat shady 'social worker' Cobra Bubbles.
The Grand Councilwoman is also clearly a member of the Lazax.
My theory is that this film is clearly a prequel to the TI and Rex universe. For anyone keen on the lore, I'd definitely suggest watching this move.
