Nomu (U.S.J.)

"Artificial Human" Noumu (脳無, Nōmu) is a villain, an Artificial Human and was a member of the League of Villains, who is one of the main antagonists of the Unforeseen Simulation Joint Arc.

Appearance
Noumu appears to be a large black humanoid monster, his body is very muscular and has many scars around it. His brain is exposed on the top of his head, while his large eyes are around it and his mouth has the shape of a bird's beak that has sharp teeth in it.

Before his transformation, Noumu had the appearance of a regular human with thick lips.

Personality
Due to his massive body experimentation, Noumu isn't capable to speak nor think for himself, to compensate this inability he is only capable of following orders and will do so without question, as shown when he follows Tomura's orders. He is very brutal with his enemies and will not show any mercy.

History
Noumu was once a small time thug. Under unknown circumstances, Noumu's body was experimented on through DNA injection from four different people, causing Noumu to acquire Quirks in the process, eventually resulting in Noumu becoming an artificial human.

Unforeseen Simulation Joint Arc
Noumu appears at the Unforeseen Simulation Joint after Kurogiri warps him and the other villains there. When Shouta knocks Tomura 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.

All Might attacks Noumu with Carolina Smash, but does little damage to him. Noumu tries to counter, but All Might dodges. All Might then uses a backdrop slam against Noumu, but Kurogiri opens a gate with his Quirk, allowing Noumu to evade the attack and then clutch onto All Might. However, half of Noumu's body is frozen by Shouto, giving All Might the opportunity to escape from Noumu. After Shigaraki orders him to get rid of Katsuki and retrieve Kurogiri, Noumu gets out of Kurogiri's gate, but his frozen half is then shattered. After getting out, Noumu begins to regenerate, regaining his lost limbs. He then attacks Katsuki, but his punch is blocked by All Might who is sent back a distance by Noumu's punch.

However, Noumu's attack forced Katsuki to evade, allowing Kurogiri to escape from Katsuki. Noumu and All Might engage in a fist fight, punching each other blow for blow (although Noumu has the upper hand thanks to his Quirk). All Might decides to go beyond his 100%, and, with a devastating punch, Noumu is sent flying out of the U.S.J, defeated. It is revealed that All Might's punch sent Noumu flying into a forest 400m away from the U.S.J and he is captured by the authorities, putting up no resistance whatsoever.

Field Training Arc
Noumu has been imprisoned by the Police Force, locked up in a straight jacket. The Police Force try to get information from Noumu, but he does not respond or react to anything they do. Instead, the Police Force do a DNA analysis on Noumu.

Quirk and Abilities
Shock Absorption (ショック吸収 Shokku Kyūshū): Noumu's Quirk grants him the ability to absorb the shock of any attack, but Noumu has a limit to how much he can absorb.

Super Regeneration (超再生 Chōsaisei): Noumu's second Quirk grants him the ability to regenerate anything, from injuries to limbs.

Overall Abilities: Noumu has shown to be very powerful and the strongest artificial human seen thus far, as he was able to defeat Shouta (a formidable Pro Hero) with no difficulty and was able to severely injure All Might to the point he couldn't move. Designed as a counter to All Might, he has been described as a humanoid punching bag for his combination of Quirks that allows him to take powerful blows and debilitation injuries without a thought.

Immense Strength: Noumu possesses an incredible amount of raw physical strength, being able to fight on par with All Might for a considerable amount of time.

Immense Speed: Despite his herculean bulk Noumu, beyond his surreal amount of strength is blindingly fast. Noumu was able to intercept Izuku Midoriya's full power Smash blow and able to keep up with All Might in a pummel contest.
