With just two day until Invincible season four Prime Video has released a clip of who we will see Mark Grayson fight in the upcoming season. Mark Grayson will have to live up to his namesake in order to overcome and defeat the enemies that are coming.

For those who don’t know, the show is based off of the graphic novel series under the same name. A boy named Mark Grayson gains superpowers from his father Omni-Man, and decides to be a crime fighter named ‘Invincible.’ However, this is not your average run of the mill superhero story for children. This series is graphic and not meant for the faint of heart. In the clip we see Invincible fighting a creature by the name of “Dinosaurus.” The character appears as if he could be a one off character, however if you have read the comic you will have a better understanding of what this character will offer to the story. According to Comicbook, Dinosaurus will not be the only villain standing in Invincible’s way, for the main antagonist for this season will be the Grand Regent of the Viltrumites, Thragg. In the comics Thragg is regarded as the strongest Viltrumite in the world of Invincible and his goal is to take over the galaxy, however Invincible will not allow him to do so.

The cast consists of Steven Yeun (The Rip, Crash Site), Sandra 0h (Good Fortune, Smurfs), J.K. Simmons (Grimsburg, The Accountant 2), Grey DeLisle (Batman: Caped Crusader, American Dad!), Gillian Jacobs (Wylde Pak, Chad Powers), Chris Diamantopoulos (Family Guy, Diary of A Wimpy Kid: The Last Straw), Walton Goggins (Fallout, The Righteous Gemstones), Jason Mantzoukas (Percy Jackson and the Olympians, A Man on the Inside), Ross Marquand (X-Men ’97, Tuesday’s Flu), Khary Payton (Teen Titans Go!, Krapopolis), Zachary Quinto (Brilliant Minds, The Artist), Andrew Rannells (Elsbeth, Too Much), and Melise (NCIS: Los Angeles, Escape Plan: The Extractors).

The fourth season is set to premiere on March 18, 2026 on Prime Video. It’s not too late to binge the first three seasons of the show in order to catch up for the main event.
