MIB: Invasion

MIB: Invasion is a 2025 film and the 5th and final film in the MIB franchise.

Plot
A year after the events of MIB:3, K and J go after a intergalactic criminal known as Gabriel Galaxavier. J defeats Galaxavier, but Galaxavier escapes, killing K in the process.

A week after the events of MIB: International, M gets assigned to J, who is traumatised by the death of K and they sent to track down a robotic assassin. M and J defeat the assassin, only to tell that it works for Galaxavier and that they should go to the city morgue. M and J then go the morgue with J reuniting with Laural, a former MIB agent, who does not remember J. A intergalactic bomb goes off with a holographic message from Galaxavier telling J and M to go to the Apollo site (where K neuralyzed J when he was a kid). J then opens up to M about K’s death and J’s relationship with him. J and M realise that Galaxavier is sending them on a wild goose chase and they both go to the same place where J last encountered Galaxavier. Galaxavier then shows up and reveals his plans cause war between every single planet in the universe, including Earth, which will allow him to take over the universe once they destroy each other by sending a assassin to kill the House of Congress. J and M escape to MIB HQ and MIB decides to go to war with Galaxavier. J and M decide to break in to Galaxavier’s ship by using the two flying saucers disguised as the World’s Fair. J and M then break into the ship and battles with Galaxavier. M then neuralyzes Galaxavier with an alien neuralzer, causing Galaxavier to crash the ship, killing him in the process. MIB then neuralyzes the Earth with their international satellite.

J then reveals to M that when K died, he vowed that he would retire from MIB (the same way K tried to do in the first movie). J then asks M to neuralyze him, but M refuses, saying that she has learned so much from J. J then decides to continue to work at MIB until he dies. J and M become partners and fly off into the screen, neuralyzing the audience in the process.
