Nomu (U.S.J.)

"Artificial Human" Nomu is 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
Nomu 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, Nomu had the appearance of a regular human with green hair and thick lips.

Personality
Due to his massive body experimentation, Nomu is not able to speak nor think for himself, so 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
Nomu was once a small thug. Under unknown circumstances, Nomu's body was experimented on through DNA injection from four different people, causing Nomu to acquire Quirks in the process, eventually resulting in Nomu becoming an artificial human.

Unforeseen Simulation Joint Arc
Nomu appears at the Unforeseen Simulation Joint after Kurogiri warps him and the other villains there. When Shota knocks Tomura Shigaraki down onto the ground, Nomu appears before Shota and fights him, defeating him with ease. When Shota uses his Quirk to save Tsuyu Asui from Tomura, Nomu smashes Shota'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 Nomu with Carolina Smash, but does little damage to him. Nomu tries to counter, but All Might dodges. All Might then uses a backdrop slam against Nomu, but Kurogiri opens a gate with his Quirk, allowing Nomu to evade the attack and then clutch onto All Might. However, half of Nomu's body is frozen by Shoto Todoroki, giving All Might the opportunity to escape from Nomu. After Tomura orders him to get rid of Katsuki Bakugo and retrieve Kurogiri, Nomu gets out of Kurogiri's gate, but his frozen half is then shattered. After getting out, Nomu 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 Nomu's punch.

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

Vs. Hero Killer Arc
Nomu has been imprisoned by the Police Force, locked up in a straitjacket. The Police Force try to get information from Nomu, but he does not respond or react to anything they do. Instead, the Police Force did a DNA analysis on Nomu.

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

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

Overall Abilities: Nomu has shown to be very powerful and the strongest artificial human seen thus far, as he is able to defeat Shota (a formidable pro hero) with no difficulty and is able to severely injure All Might to the point where he could not 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 debilitating injuries without a thought.

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

Trivia

 * Nomu's name, "脳無" means "brainless".
 * Nomu shares similarities with DC supervillains such as Doomsday and Validus. All are mindless enemies bioengineered to be physically larger and more powerful than their respective heroes (Superman and All Might), with Nomu and Validus both having exposed brains. They often require the assistance of other superheroes to defeat them.
