I Thought You Were Stronger

In the Viltrumite Prison, Nolan tears through defense robots and guards as part of the grim preparation for his execution, earning cold congratulations from General Kregg. On Earth, Mark comes home to find Angstrom Levy holding Debbie and baby Oliver hostage. Failing at first to place the scarred stranger, Mark eventually recalls the harbor explosion that mangled Angstrom, who blames him bitterly and refuses every offer of help. Angstrom's power lets him fling Invincible through a series of bizarre realities, from a world of intelligent raptors to encounters with a spider-powered hero and a pack of zombies.

As he teleports his enemy around, Angstrom is haunted by memories from countless dimensions where alternate, murderous versions of Invincible butchered his other selves and families. Convinced Mark is a monster in every timeline, he grows more unhinged, dismissing Mark's insistence that he once tried to save him at the harbor.

Left alone with Angstrom, Debbie fights back, smashing a flowerpot over his head and slashing him, but he snaps her wrist and vows to hurt the whole family. When Mark finally pins his tormentor and sees his mother's broken arm, his restraint evaporates. Angstrom reveals that his healers rebuilt his body with enhanced strength, and the two crash into a barren wasteland. There Mark unloads all his pent-up fury, beating Angstrom into a bloody ruin and finishing with a double-fisted blow to the chest. Believing he has killed him, Mark stares at his bloodied hands and mutters, in horror, that he thought his enemy was stronger.

Cecil and the GDA secure Debbie and Oliver as Mark spirals into guilt. Alternate future heroes, including a Monster Girl, a Bulletproof, and versions of Atom Eve and Robot, arrive to send Mark home, and future Eve confesses her love before he steps back into his own timeline. Subplots close threads across the cast: Rudy and Amanda begin dating, the Immortal discovers Dupli-Kate faked her death, and explorers Jane and Riley awaken Ka-Hor, who insists he needs a male host. In the Viltrumite Prison, Nolan meets fellow inmate Allen the Alien and admits he misses his wife. The eighth and final episode of the second season, and the sixteenth overall, it introduces Invincible to the multiverse.
