Invincible Season 4 to bring Thragg, Dinosaurus, and the Viltrumite war. Check new villains, release date and other details

Amazon Prime Video is reportedly working on the fourth season of Invincible. The highly anticipated season promises to raise the stakes with the arrival of Thragg—the most dangerous Viltrumite yet—along with new villains like Dinosaurus and The Devil, while also bringing back fan favorites such as Battle Beast and Omni-Man.

The series, based on Robert Kirkman’s acclaimed comics, has already captivated audiences across its first three seasons, earning praise from both critics and viewers. Now, Season 4 looks set to dive even deeper into the universe’s darkest conflicts.

Invincible Season 4 Plot

The new storyline will pick up directly from Issue #66 of the comics, beginning the epic Viltrumite War arc. Key events include Allen the Alien and Omni-Man’s journey through space, the arrival of Dinosaurus, and the expanding threat of the Viltrumite Empire.


While the series has stayed close to the comics, fans know it isn’t afraid to diverge—Season 3’s unique Hell storyline proved that the show is willing to add original twists. Kirkman has hinted that viewers can expect side plots and possibly special episodes to enrich the main narrative.

Battle Beast, who narrowly survived in Season 3, will return with an expanded role. His insatiable thirst for combat is expected to push him into pivotal clashes. Meanwhile, The Devil—teased in a Season 3 post-credits scene—will finally step into the spotlight.

At the core of the season is Thragg, the most powerful and ruthless Viltrumite ever introduced. After Conquest’s failure to eliminate Invincible, Thragg arrives to take matters into his own hands, setting the stage for the deadliest confrontation in the series so far.
