Invincible season 4, episode 4 has revealed that Bruce Campbell voices the demon character Satan, building on his brief appearance in the season 3 post-credits scene. The episode, titled 'Hurm,' sees Damien Darkblood summon Invincible to hell to aid Satan against a rising threat. Campbell's performance shifts from understated to high-energy after a power restoration.
Bruce Campbell first appeared in Invincible at the end of season 3, voicing an unidentified demon alongside Damien Darkblood, played by Clancy Brown. Season 4, episode 4, 'Hurm,' names the character Satan, depicted initially as an elderly, shriveled figure diminished in power. This portrayal marks a new arc original to the animated series, diverging from the Invincible comics. Damien Darkblood summons Invincible to the Under-Realm, or hell, to help Satan reclaim an ancient artifact from a new power emerging in the Earth's depths. The artifact restores Satan's former might, transforming him into a massive, towering monster. Campbell delivers an understated performance early on, evolving into a high-energy presence reminiscent of his demon-slaying Ash Williams from the Evil Dead trilogy. This casting fits Campbell's history in the genre, including cameos in the Tobey Maguire Spider-Man films and Doctor Strange in the Multiverse of Madness. Invincible boasts a star-studded voice cast, featuring Steven Yeun, J.K. Simmons, Sandra Oh, Gillian Jacobs, Walton Goggins, Mark Hamill, Sterling K. Brown, Seth Rogen, and Mahershala Ali. The series streams Wednesdays on Prime Video.
