What Have I Done? (Invincible)

"What Have I Done?" is the seventh episode of the third season of the American adult animated superhero television series Invincible, based on the comic book series of the same name by Robert Kirkman, Cory Walker, and Ryan Ottley. Written by Robert Kirkman and directed by Haylee Herrick, Dan Duncan and Shaun O'Neil, the episode adapts elements of the "Invincible War" storyline from the original comic volume Still Standing, notably issue #60, and is noted for its large-scale action, emotional depth, and significant plot developments.

The episode is structured into four segments—labeled "Day One," "Day Two," "Day Three," and "End of the War" depicting the rapid escalation and resolution of the "Invincible War" within a single 50-minute episode. This format, inspired by the comic’s issue #60 where the war unfolds across four chaotic days, expands the timeline across three days and a concluding aftermath.

The episode premiered on Amazon Prime Video on March 6, 2025, as part of the season's weekly release schedule following a three-episode premiere on February 6, 2025.
