Invincible Season 4 opens a new, darker chapter for Mark Grayson and the people around him. The coming season will move into the Viltrumite War arc from the comics, and Prime Video has confirmed several major antagonists who will shape the plot. Those additions change the stakes for Mark’s fights and for the show’s family conflicts.

Most of the confirmed names are ones longtime readers will recognise, but the show is making clear choices about how to use them. Producer and creator of Invincible, Robert Kirkman's comments at conventions and casting announcements have already shown who will appear and how some characters will be handled on screen.

Below are the five villains Prime Video has confirmed will play important roles in the season and what each arrival likely means for the story.


Thragg arrives as the Viltrumite leader and major threat in Invincible Season 4

Thragg is the Grand Regent of the Viltrumite Empire in the comics, and his presence signals the shift to the large-scale Viltrumite War. His arrival raises the level of danger for everyone on Earth because Thragg is written as the strongest and most ruthless Viltrumite. TheDirect lists Thragg among the confirmed villains for the new season, which suggests the show will stage wider battles beyond one-on-one fights.


Dinosaurus appears with both his human side and monster side shown

Creator Robert Kirkman confirmed at San Diego Comic-Con that Matthew Rhys will voice Dinosaurus and the character’s human alter ego, David. This casting indicates the show plans to show both the monstrous transformations and the human motives behind them, so viewers should expect scenes that contrast David’s intentions with Dinosaurus’s actions.


The Devil is returning after being teased in earlier material

A demonic figure was hinted at in material tied to Season 3, and reporting now lists “The Devil” among the Invincible Season 4 threats. That tease means the show will not limit itself to alien empires and super-soldiers. Supernatural elements will also factor into some plot threads.


Battle Beast comes back as a warrior who shifts the field of combat

Battle Beast showed up earlier in the series as a fighter who loves battle more than causes. Reports say the character returns for Invincible Season 4, and his presence usually forces brutal, extended fights that reveal how strong other characters really are. His scenes tend to be physical tests for Mark and the other heroes.


Omni-Man returns with his choices set to complicate family and war dynamics

Omni-Man has been both father and foe to Mark. His reappearance in the season makes the human side of the story, family, loyalty, and hard personal choices as important as the big external battles. Sources list Omni-Man among the confirmed figures who will shape the season’s emotional and conflict arcs.


These five characters of Invincible Season 4 together point to a season that balances large-scale war scenes with personal confrontations. The casting notes and convention reveals so far show the showrunners want to present key comic moments while also using voice actors to draw out each villain’s human side.

For viewers new to the series, Season 4 promises clear, high-stakes conflicts that change how Mark and his world must react.
