J.K. Simmons (Omni-Man) has confirmed that the Invincible team has already begun work on the show's fourth season.
It's not just his introduction that's been teased either, as fans think they've worked out who's playing him as well.
Mark is better, faster, and stronger in Invincible Season 3 Episode 1, and he puts his strength to the test against Doc Seismic.
