The Invincible Season 3 finale, titled “I Thought You’d Never Shut Up,” will stream on Prime Video on Thursday, March 13, at 12:00 AM PT. In this episode, Mark faces his biggest challenge yet as he fights the strongest Viltrumite in the series so far. Earlier, Viltrumites warned about someone much more dangerous, and now, Mark is in serious trouble.
Recently, IGN has shared an exclusive clip from the Invincible Season 3 finale. It features supervillain Conquest (Jeffrey Dean Morgan), a battle-scarred enforcer of the Viltrum Empire, who debuted in last week’s episode during the alternate universe Invincible invasion. His mission is simple—make Mark Grayson (Steven Yeun) prepare Earth for takeover. Watch the clip below.
According to IGN, “Conquest appears in the aftermath of a particularly devastating conflict on Earth—bringing with him an ultimatum from the Viltrumite Empire. Either Invincible carries out his duty and conquers his homeworld in the name of the empire—or Conquest will kill him and finish the job himself. Thus begins the most violent and desperate battle of Mark Grayson’s life.”

In Invincible Season 3, Yeun returns as Mark Grayson/Invincible, alongside Sandra Oh as Debbie Grayson, J.K. Simmons as Nolan Grayson/Omni-Man, Christian Convery as Oliver Grayson/Kid Omni-Man, and Gillian Jacobs as Samantha Eve Wilkins/Atom Eve.
The supporting cast includes Jason Mantzoukas as Rex Sloan/Rex Splode, Zachary Quinto as Robot, Malese Jow as Kate Cha/Dupli-Kate, and Grey Griffin as Amanda/Monster Girl (human form), Rachel/Shrinking Rae, and Betsy Wilkins. Khary Payton voices Markus Grimshaw/Black Samson, Jay Pharoah plays Zandale Randolph/Bulletproof, and Ross Marquand portrays The Immortal and Rudy/Rex. Ben Schwartz joins as Shapesmith, while Walton Goggins returns as Cecil Stedman.
Synopsis: “Everything changes as Mark is forced to face his past, and his future, while discovering how much further he’ll need to go to protect the people he loves.”
