One Punch Man Season 3 Episode 10 drops this Sunday, and the Monster Association's underground stronghold is about to witness carnage on an unprecedented scale. Although Child Emperor was able to survive being resurrected by Phoenix Man (barely), the real nightmare has yet to come. The S-Class Heroes are still lost in the maze, divided, and nowhere near as strong as they need to be.

What Can You Expect from One Punch Man Season 3 Episode 10?

Following the epic showdown we saw in the last episode, One Punch Man season 3 Episode 10 is gonna change things up quite a bit. The S-Class heroes are pretty beat up and split up throughout the depths of the Monster Association's labyrinth.

Expect this next episode to show that there's more to the whole monster organization than meets the eye. Zombie Man will likely be a major character in this episode as well, since we've seen him responding to Child Emperor's messages from the last episode. We're definitely going to see more from Zombie Man and get to see him battle.

The title of this episode is "Bloodbath of the Immortal," so the episode's definitely gonna be heavy on the fighting. Several character arcs are climaxing as they prepare for the end of the season. Meanwhile, Saitama continues to take it easy, exploring the underground base for what will be a big final showdown.


What Happened in One Punch Man Season 3 Episode 9?

In Episode 9 called "Brave Child," you have probably seen one of the craziest fights of Season 9. When Child Emperor nearly ran out of time trying to save Waganma from being killed by the Monster Association because they were hiding in their underground base at the time, he faced Phoenix Man. Phoenix Man took Child Emperor's defeat as his first resurrection; he evolved to a dragon-level threat status.

In order to protect himself against Phoenix Man, Child Emperor needed to use his last resort weapon. Phoenix Man broke through the shields Child Emperor had on his defense and completely demolished Child Emperor with a huge amount of power.

The Brave Giant was the mechanical suit that was built underneath the Monster Association and activated by Child Emperor with drills, which he strategically placed across the Monster Association site. The Brave Giant had dragon-level strength, but it needed to be activated within three minutes; otherwise, it self-destructed.

An even stronger Phoenix Man returned to a form called the Phoenix Brilliant Eagle, where he was now at a rank of cadre level within the Monster Association hierarchy. He proved his strength by tearing off the arm of the Brave Giant with very little effort.

In One Punch Man Season 3 Episode 10, Saitama had an encounter with his former enemies Hellfire Flame and Gale Wind, who had been resurrected thanks to Child Emperor's electric attack and Phoenix Man's power to bring people back to life. While they were wandering around naked inside the tunnels, they ran into Saitama. However, instead of fighting with him, they made a short joke out of it and quickly left.

One Punch Man Season 3 Episode 10 is definitely worth tuning in for the continuing buildup of the Monster Association Story Arc because Episode 10 does seem like a key point in the overall story, and the convergence of numerous plotlines will lead to even bigger action scenes.
