[Warning: This article contains spoilers for season 4, episode 4 of “Invincible”]

This weekly released episode drags Mark (Invincible) into the Underrealm, teaming up with Damien Darkblood and even Satan himself to battle the magma villain Volcanikka and her forces, all while confronting his own moral doubts and the toll of his violent life.

The episode leans hard into heavy metal action, dark humor, and surreal imagery including a wild Molten Crown retrieval and a brief Slayer soundtrack cameo making it striking but somewhat disconnected from the season’s main Viltrumite conflicts.

Fans are divided though… some love the bold detour into The underworld and the exploration of good and evil, while others criticize pacing issues and animation shortcuts.

The episode ends on a pretty tense cliffhanger with Omni Man and Allen the Alien appearing in orbit, signaling the Viltrumite War’s return. Overall, “Hurm” is a chaotic episode that tests Invincible’s strength and morality but leaves some viewers questioning its place in the season.
