Invincible's evil variants of Mark Graysons are abruptly shunted out of the episode before the climax, setting up their potential return.

The final episode of Invincible Season 3 will be released on Prime Video on March 13, 2025, at 12 AM PT. The season includes eight episodes. Major events like the Invincible War and the arrival of Conquest are expected.

It's worth noting that this didn't come entirely out of nowhere though. Angstrom Levy, the genius who kickstarted this war, appeared all the way back in the first episode of season 2. And like in the comics, his storyline, the build-up to The Invincible War, actually developed over a long period of time.
