Nomu

Artificial Humans, also known as Noumus, are individuals who were modified by the League of Villains.

Appearances
Though they may have different appearances, in size, color, shape and extremities, they all have their brains exposed, with their eyes planted in them.

Personalities
The Artificial Humans don't have a personality; they are only able to follow orders and can't think for themselves.

Ultimate Space & Jams Arc
The artificial human Noumu fights alongside the League of Villains against the students of Class 1-A. In the end he is defeated by All Might and is taken into custody by the Police Force.

Field Training Arc
Tomura Shigaraki orders three artificial humans to wreck havoc in Hosu. One of the three artificial humans throws a Pro-Hero into a driving train. Gran Torino then charges at the villain.

Powers and Abilities
Each Artificial Human posses multiple Quirks, some like Noumu's have two specific Quirks that were given to him counter All Might's.

Artificial Humans are brain dead due to the heavy experimentation and Quirk implantation performed on them (as seen in Noumu's case); this has caused the Artificial Humans to lose their speech, personality and response. The Artificial Humans only respond and take action through the orders of their superiors, as Noumu did not attempt to fight back from being restrained by the Police Force, nor did he respond to any question that the Police Force gave him.
