Marvel: Strength Manipulation

Nezhno Abidemi (Gentle)
Nezhno has the ability to increase the muscle mass of his body, allowing him to drastically increase in size and strength almost instantly. Nezhno's powers, while great, are also temporary and self-destructive; the user of his powers puts massive strain on his body, and most instances of using his powers results in Nezhno passing out. Furthermore, Nezhno states that the user of his powers will ultimately kill him. His tattoos, which are made of vibranium, are meant to keep his powers in check. However, Nezhno's resting strength gradually increases every time he uses his powers, and, according to Nezhno, the vibranium will eventually fail, meaning his body will no longer be able to control its own power, causing him to die.
