Expatriate of the U.S government, currently involved in some crazy scheme to save the world, and his own skin.
Movers are powerful telekinetics who are trained to identify the specific atomic frequency of a given material and alter the gravitational field around it, usually causing the nearby air to appear warped. This allows them to move both animate and inanimate objects. Advanced Movers can work at the molecular level, creating Energy shields in the air around them or create Power Fists and kicks, a strike that delivers 3x the power than a punch delivered normally. Nick is a Mover, but not very advanced one.
