Quirk
Cell Activation: Katsuma's Quirk allows him to speed up the activity of cells in the body of anyone he touches. It’s implied he can do this to himself as well.

It can be used to heal a person's wounds as well as improve their physical performance. After prolonged usage, Katsuma can suffer from exhaustion. So far, his Quirk has been shown to work on people with Type O, A, and B blood.
