I'd like to change:
The power to take the potential energy stored in an object and convert it to kinetic energy thus “charging” that item with explosive results.
Into:
The ability to store and absorb a massive amount of energy and channel this energy into his physical attacks. This would mean once an attack has landed 'charged' energy would be blasted into his opponent with the capability of causing immense internal damage.
With that and his new temper I can give him the codename "frenzy" and his weight would be edited to something closer to 200 to accommodate this storage of energy.
