Magic itself is a nono, but they can refer to or call their powers magic. It has to be a specific ability that functions in a mechanicaly specific way, though.

ok, im drawing my ideas from a novel series. in the series its magic but ill give you a rundown-

Death touch (requires physical contact) - Spreads physical corruption such as Necrosis on his victim, this takes a few moments to kill an average human. The spread is slower and takes more effort on Parahumans, and can be totally nullified by high level regeneration abilities. 

Raise Dead (30ft range) - Can raise the dead, returning their "soul" to the body and reanimating them, while they maintain a certain level of personality they are still under control. this ability does not work on parahumans at all. Reanimated people do have extremely high durability (as physical damage does very little to a corpse) and strength (muscles fueled by the energy of the reanimator)

Siphon Life (requires physical contact) - uses the latent life energy of a recently dead parahuman to repair the user from psysical damage such as gunshot wounds and broken bones. this also grants him weaker, and temporary access to the deceased parahuman's abilities (3-5 minutes).
((Siphon Life is operating under the assumption that there are many lowish level parahumans as well.))

if this doesnt work i expect i can come up with something else
