Prime Video made two big Invincible announcements at its Annecy International Animation Film Festival panel this week: Jack Quaid will be joining the cast as the voice of Gravitator in season five, and the show has already been renewed for season six. Cue the “Mark, this is good news!” memes. Mark, this is good news!!!!!! pic.twitter.com/qZl0FA6bh1 — INVINCIBLE (@InvincibleHQ) June 24, 2026 The Prime Video animated series, based on Robert Kirkman’s comics of the same name, just wrapped up its fourth season in April, which was its most-watched season to date, according to a press release. The show follows Mark Grayson (Steven Yeun), aka Invincible, a teenager who gains superpowers that render him nigh-indestructible, as he struggles to just be a teenager while battling terrestrial and extraterrestrial foes, including his father, Nolan (J.K. Simmons), aka Omni-Man. While Quaid’s character, Gravitator, won’t be introduced until season five, we know from the comics that he is a thief and a gifted engineer who turns his life around after a chance encounter with Invincible. Attendees at Annecy were treated to an exclusive video clip of Gravitator, but the rest of us will have to settle for just an image.
