Nomu

Nomu is a villain from the manga/anime series, My Hero Academia. He is an artificial human, specifically created to kill the No. 1 hero All Might, the Symbol of Peace. He is one of the main antagonists in the Unforeseen Simulation Joint Arc.

Personality
Nomu is a mindless beast, as he is unable to think and speak for himself. As a result, he relies on others to speak for his actions. He's not completely mindless, however, as he is shown to be able to take orders from Tomura Shigaraki. Nonetheless, he is a complete monster, determined to kill with no hesitation.

Powers and Abilities
Unlike most of the characters in My Hero Academia, Nomu is one of the few villains to have multiple Quirks, as a result of DNA injection from four different people. These Quirks include:

Shock Absorption: This Quirk allows Nomu to absorb shocks from any attacks, as well as granting him immense durability. It should be noted, however, that he can only absorb shocks, and not nullify them, meaning that his Quirk has a limit.

Shock Regneration: This Quirk grants Nomu a regenerative healing factor, as he is capable of regenerating missing limbs in a matter of seconds.

Immense Strength: Nomu possesses a high degree of super strength. He is capable of breaking bones like twigs and create small craters in the ground with ease. His strength rivals that of All Might's at 100%.

Immense Speed: Despite his hulking size, Nomu is extremely fast, as he was able to save Tomura from Izuku Midoriya in the nick of time and save him once more when All Might charged towards him. He was also able to keep up with All Might in a fist match, until All Might started going beyond his limit.

Overall, Nomu is a very powerful villain, and currently seems to be the strongest artificial human created. He was able to defeat Eraserhead with little to no effort, to the point of leaving heavy injuries on him. Because he was created to be All Might's counter, he rivals him in strength, speed and durability.
