Invincible Season 4 Plot

The Invincible Season 4 storyline will continue from Issue #66 of the comics. It will show Allen the Alien and Omni-Man’s journey in space, the arrival of Dinosaurus, and the beginning of the Viltrumite War.

Battle Beast, who survived in Season 3, will also return. Fans can expect his role to expand in the upcoming episodes.
