Nomu is a beast metaphorically and literally. It is the result of experimentation involving combining multiple quirks into one human body. This Nomu is all about soaking up damage and throwing it right back at his rival.
Nomu's Response ability requires it to commit a foundation and in return only take six damage from an attack. If the attack would do twenty damage, Nomu can simply not block the attack and instead commit one foundation to take 6 damage. Damage absorption is the name of this quirk.
Next Nomu has an Enhance ability that gives it's non-throw attack a damage bonus equal to the difficulty of the attack. If the attack has a five difficulty then it receives five damage. This effectively doubles the power of most attacks when Nomu is attacking! Super strength quirk activate!
