# 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 comics, 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 in one chaotic day, 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.

## Plot

In a flashback, Angstrom Levy is saved and nursed back to health by a trio of advanced cybernetic surgeons called the "Technicians" following his presumed death at the hands of Mark Grayson / Invincible. In the present, Angstrom uses his multiversal powers to summon 18 evil alternate variants of Invincible from across the multiverse and has them wreak havoc on his Mark's Earth to tarnish Mark's reputation. Mark arrives at Payton Penitentiary and engages one of the variants, "Mohawk Invincible", whom he knocks unconscious. Scott Duvall / Powerplex, a supervillain Mark recently defeated, escapes in the chaos, killing an Invincible variant in the process. Over his mother Debbie's protests, Mark's half-brother Oliver joins the fight while Global Defense Agency (GDA) director Cecil Stedman rallies more heroes to face the threat and prepares undead cyborgs called "Reanimen" to provide further aid.
As the war intensifies, Mark and his girlfriend Atom Eve deduce Angstrom's involvement before she is injured by "Omni-Invincible", leading to Mark prioritizing her over the battle. Cecil deploys Reanimen to save Mark and Eve and kill another variant while Omni-Invincible escapes. Over time, Mark and Guardians of the Globe member Darkwing kill two more variants, though Darkwing is presumed dead, while former Guardian Rex Splode sacrifices himself to kill a fourth variant and cover his friends Monster Girl, Bulletproof, and Rudy Connors' escape.
On the third day of their attack, Angstrom orders the remaining eight variants to gather above Mark's house for the second phase of his plan. Refusing to sustain further casualties, they attempt to betray him, but Angstrom strands them in a desolate dimension. Mark faces Angstrom, who briefly overpowers him with a multitude of drones before Mark subdues him. Oliver arrives to convince Mark to kill Angstrom, arguing that he is too dangerous to be kept alive. However, Angstrom flees, losing an arm in the process. The Technicians turn on Angstrom, demanding his obedience.
In the aftermath of the war, Mark reflects on its heavy toll and how public trust in him has been shaken. As he assists in rescue and recovery efforts, an aged Viltrumite envoy named Conquest arrives and expresses disappointment in Mark's lack of progress in subjugating Earth for the Viltrum Empire. Devastated and enraged by the destruction directed at him, Mark charges at Conquest to vent his rage.

## Production
### Casting

Steven Yeun leads the episode as Mark Grayson / Invincible in the episode, portraying 18 alternate versions of the character, each distinguished by unique vocal inflections. His performance, which includes variants such as a Mohawk-wearing Invincible and one in an Omni-Man-inspired suit, was noted as a highlight.
The episode sees the return of Sterling K. Brown as Angstrom Levy, whose multiversal attack drives the central conflict. The supporting cast includes Gillian Jacobs as Atom Eve, Walton Goggins as Cecil Stedman, and Zachary Quinto as Robot. Ross Marquand reprises his roles as The Immortal and Rudy Conners, while Jason Mantzoukas voices Rex Splode. Grey DeLisle and Chris Diamantopoulos also return as Shrinking Rae and Donald Ferguson, respectively.
Several new and returning characters appear during the multiversal battle, including Silver Age-inspired heroes. The episode also features Jeffrey Dean Morgan as Conquest, Jonathan Banks as Brit, Aaron Paul as Powerplex, and Chloe Bennet as Riley, the tomb raider. Clancy Brown voices Ka-Hor, Doug Bradley as voices of The Technicians, and Gary Anthony Williams as the voice of a news anchor. Additional voices include Fred Tatasciore as Adam, and Misty Lee and Jordan Reynolds in various supporting roles.

### Music

A standout track featured in this episode is "When the Party's Over" a 2018 single by American singer-songwriter Billie Eilish from her debut album When We All Fall Asleep, Where Do We Go? (2019), written and produced by her brother Finneas O'Connell. The song, a minimalist piano ballad with choral influences, plays during a pivotal sequence in the episode, enhancing its emotional weight. It accompanies the aftermath of Rex Splode’s sacrificial death on "Day II," where he detonates himself to defeat Retro Invincible, saving Robot and others at the Teen Team base. As the soft melody contrasts the preceding violence, the scene depicts a ruined world strewn with bodies, amplifying the sense of loss and emptiness.
