Nomu (U.S.J.)

Noumu (脳無, Noumu) is a villain and one of the main antagonists of the Rescue Trial Arc. His goal is to kill All Might "The Symbol of Peace".

Appearance
Noumu appears to be a large black monster with his brain exposed on the top of his head. He also has large eyes and sharp teeth.

Personality
Noumu doesn't appear to be able to speak, although he appears to be capable of following orders without question, as shown that he will follow Shigaraki's orders and he is very brutal with his enemies and will not show any mercy.

Rescue Trial Arc
Noumu appears at the Ultimate Space and Jams after Black Mist warps him and the other villains there. When Shouta knocks Shigaraki down onto the ground, Noumu appears before Shouta and fights him, defeating him with ease. When Shouta uses his Quirk to save Tsuyu from Shigaraki, Noumu smashes Shouta's head into the ground. He then blocks Izuku's One For All empowered punch, not even receiving a single scratch from it.

Shigaraki Tomura
Because Noumu doesn't have the ability to think for himself, he relies of Shigaraki to think for him.

Trivia

 * Supposedly, his base power is as strong as All Might's.
