Invincible Season 3 Episode 7 Review: What Have I Done?
Invincible Season 3 Episode 7, “What Have I Done?” sees Mark square off against an unimaginable threat with devastating results, effectively building on the moral dilemma established last week. Powerplex makes a brief resurgence, and with that ending, we see the Invincible War will inevitably give way to the Advent of Conquest. It’s an action-packed, high-octane affair.
What Have I Done?
This penultimate outing is almost nonstop action. The creative team wastes no time getting to the meat of the narrative — Mark Grayson versus Angstrom Levy’s army of Evil Variant Marks. In a way, this balls-to-the-wall approach to the Invincible War makes viewers feel like we’re part of the fight. We’re immersed almost instantly into the story.
“What Have I Done?” maintains this breathless momentum from start to finish, even in the more dialogue-heavy scenes. These scenes are a necessary break from the ultraviolence and gore and are crucial to the plot.

Additionally, the episode showcases the most superheroes we’ve ever seen on Invincible. Unfortunately, most are no match for the Alter Marks (as I’m calling them). The unfettered violence and bloodshed isn’t anything out of the ordinary for this series, but it’s just a lot of the aforementioned at once. Oof. Thankfully, it’s executed well.
A Jack of All Voices
Steven Yeun puts his impressive vocal versatility on display in “What Have I Done?” He makes the Alter Marks sound, well, like Mark, while adding a twist to each one. You can tell he had a blast voicing these different characters in the booth. It’s always a guaranteed good time for the audience if actors are relishing their roles.
Jason Mantzoukas also gives his all this week as Rex. The immense growth for Rex throughout the past three seasons has felt organic and earned. His relationship with Rae is so sweet, too. All this makes his death that much more gut-wrenching.

Mantzoukas has such a distinctive voice, and it really works for a character — one who’s typically comedic relief — like Rex. He can do comedy and drama; he can go larger-than-life and pull back when needed.
The Return of a Foe
Angstrom Levy’s return has been teased all season on Invincible. I should’ve known he wasn’t off the board. After all, it’s the age-old TV rule: No body, no death. Sterling K. Brown is another wonderful vocal talent whose voice boasts an imposing, formidable air. Why wouldn’t you bring him back?
His return and ultimate revenge against Mark — by having the Alter Marks destroy the world — sends our titular hero to a dark place. He realizes he never actually killed Angstrom, but the urge to do so is overwhelming in “What Have I Done?” However, Oliver’s stamp of approval regarding Angstrom’s murder gives Mark pause.

He’s clearly thinking about the example he might set for his little brother. Ultimately, Angstrom almost slips through Mark’s fingers entirely, leaving an arm in his wake as he falls through a portal. Mark is now left with regret for not acting sooner. Cecil reminds him, though, that Mark’s strong moral compass sets him apart from his evil variants.
Being the Light in the Dark
That’s the whole point, isn’t it? Mark is beset by corruption, darkness, and unmitigated violence from all sides. He battles his half-Viltrumite nature to ensure it doesn’t overpower his humanity. He refuses to be like his father. Powerplex might view Mark through a black-and-white lens, but there’s so much more nuance to superhero-ing than he realizes. The series deftly addresses this.
Now, with the arrival of Conquest, Immortal and Dupli-Kate’s retirement, Rex’s sacrifice, and Eve out of commission, Mark will have to face even greater threats sans allies. Invincible might be strong, but can he beat the second most powerful Viltrumite? And where is Omni-Man?
The stakes are higher than ever. However, if there’s anyone who can be a light in the dark, who can send evil packing, it’s Mark Grayson.

Stray Observations:
- Donald gives major Two-Face vibes in “What Have I Done?”
- At least The Pentagon doesn’t have to change the parking sign this time. Parking will continue to be in the rear, folks.
- I’m very glad Invincible doesn’t go the “Bury Your Gays” route with William and Rick. We need some sunshine in this almost oppressively bleak episode.
- I love the Billie Eilish needle drop — “when the party’s over” is a surprisingly apt tune for this narrative.
- The snapping of Eve’s leg almost made me queasy, and it takes a lot for that to happen. Ew.
- I can’t believe Rex Splode sploded himself. I should’ve known he was doomed when he embarked on a relationship with Rae.
- Hats off to the Technicians who put Angstrom back together. Those are some damn good surgeons.
- I’m glad we got a resolution to the Jane/Riley/Ka-Hor storyline. Those poor women are finally free.
