What Happens in Episode 10

Episode 10 is projected to be a major narrative turning point, setting up the climax and conclusion of the Monster Association Arc:

The Monster King Revealed: The core leader of the Monster Association, likely Monster King Orochi, makes his formal appearance or unleashes his full power, overwhelming the surviving S-Class Heroes with ease. This moment serves to raise the stakes higher than any previous threat.

A Hero’s Downfall: One or more prominent S-Class Heroes, having exhausted their limits against the earlier threats, are decisively defeated by the newly revealed superior monster, emphasizing the gravity of the situation.

Saitama’s Breakthrough: After being lost or distracted in the sub-levels, Saitama finally blasts his way into the main chamber or confrontation site. His appearance, following the heroes’ devastating defeat, provides the trademark comedic and powerful tonal shift of the series.

The Setup for the True Battle: The episode will likely conclude right as the confrontation between Saitama and the major threats begins (Orochi, potentially combined with Psychos or other high-level executives), leaving the audience on a massive cliffhanger for the next episode.

The episode expertly balances despair and hope, showing the absolute limits of the S-Class Heroes before introducing the one character who operates beyond all limits.

Why You Shouldn’t Miss Episode 10

Episode 10 is essential viewing as it brings the season’s focus to the ultimate threat and the main protagonist. It’s the perfect blend of high drama, power scaling climax, and series-defining comedic timing.

Fans will highly value Episode 10 for the terrifying visual reveal of the Monster King’s true power, the unforgettable entrance of Saitama at the most desperate moment, and the dramatic setup for the season’s final battles.

This is the episode where the action ceases to be a war and becomes a definitive encounter between absolute evil and absolute power.

💬 My Personal Take:

“Episode 10 is pure payoff for the entire season’s buildup. Seeing the final boss monster unleashed and easily crush the strongest heroes is a necessary moment of despair, which makes Saitama’s inevitable, anticlimactic entrance so much more satisfying. The episode’s success hinges on making the audience truly believe the world is doomed, just before the bald savior arrives.”
