Thunder Drop is one of Cole's super powers. Cole jumps from a high place, charges his body with electricity, then hits the ground at full force, sending a shockwave of energy in all direction to all enemies. It's been theorized that Cole, while in mid air, collects the natural electrons from the atom particles of normal air. The longer he stays in contact with the wind during his fall, the more electrons he gathers and the more damage the move does when it hits the ground.
