One-Punch Man Episode 11: The Dominator of the Universe

The S-Class Heroes battle Lord Melzargard, a mud-like alien commander, while Saitama prepares to confront Lord Boros, the leader of the Dark Matter invaders.

The episode opens with the S-Class Heroes—Metal Bat, Puri Puri Prisoner, Atomic Samurai, and Silverfang—continuously attacking Melzargard, a shapeshifting mud creature with multiple heads. Despite their relentless assault, their attacks prove ineffective as Melzargard reforms himself after each strike. The A-Class Hero Iairon, who has lost an arm in the battle, urges them to reconsider their strategy, but the S-Class Heroes refuse to listen and continue their direct approach.

During the fight, the heroes discover Melzargard's weakness: five tiny blue marbles that form the core of his consciousness beneath the mud. As they begin targeting these cores, Melzargard grows frustrated with the prolonged battle. He decides to call the mothership and request a massive bombardment of the area. Before one of his heads can escape to relay the message, Metal Bat intercepts it and destroys it with a powerful swing.

The battle intensifies as Melzargard manages to strike Silverfang, throwing the elderly hero through several brick walls. Despite this setback, the heroes continue their assault and successfully destroy most of Melzargard's heads. With only one head remaining, victory appears within reach for the heroes.

Meanwhile, Saitama confronts Lord Boros, described as the greatest evil Saitama has yet faced. The episode ends with the question of whether this battle will finally require more than one punch from Saitama.
