Prime Video dropped the first full trailer and images for Invincible season 4 on Jan. 21, 2026, and they reshape the show’s central conflict: father and son may be on the same side — at least for now — as a Viltrumite war looms. The new footage sets the stage for a galaxy-spanning fight and confirms the season premieres March 18.
What the trailer shows
The trailer opens with high-impact action and key character moments, including a tense reunion between Mark Grayson (voiced by Steven Yeun) and Omni-Man (J.K. Simmons). In a major reveal, Omni-Man — who once attacked Earth on behalf of the Viltrumite Empire — is recruiting his estranged son to help confront the Viltrumite leadership.
Meet Thragg and the returning veterans
The clip gives viewers their first look at Grand Regent Thragg, voiced by Lee Pace, the ruthless Viltrumite leader who will be central to the new season’s threat. The Global Guardians, the franchise’s premiere hero team that was decimated in season 1, are also shown reforming with both veterans and newer heroes back in action.
New allies and enemies
Season 4 introduces several characters who raise the stakes: Dinosaurus (Matthew Rhys) and Universa (Danai Gurira) arrive to complicate Mark’s life, while brief shots tease recruits Tech Jacket and Space Racer joining the fight. The show’s official logline makes the stakes clear: “While the world recovers from catastrophe, a changed Mark fights to protect his home and the people he loves, setting him on a collision course with a threat that could alter the fate of humanity forever.”
Context and comic roots
Invincible, based on the long-running Image Comics series by Robert Kirkman and Cory Walker (with Ryan Ottley handling most art across the run), continues to hew closely to the source material. Season 4 looks to adapt one of the comic’s biggest arcs — an all-out Viltrumite conflict — while keeping the show’s signature mix of brutal action and darkly comic moments.
Fan and industry reaction
Fans started circulating the first look images and clips on social platforms as soon as they appeared. Outlets and social accounts, including a DiscussingFilm post that shared season 4 images on Jan. 21, amplified excitement about Thragg’s debut and the Mark/Omni-Man alliance. Conversations online highlight anticipation for large-scale battles and how the animated series will handle the comic’s explosive moments.
What to expect next
Prime Video confirmed the season 4 premiere date as March 18. The series already has a fifth season locked in, so viewers can expect season 4 to set up even bigger consequences as the Viltrumite war unfolds. All three previous seasons are streaming now on Prime Video for anyone who wants to refresh before the new episodes drop.
