Power: Choi Seungjoo is able to redirect and dampen arbitrary amounts of an object's momentum. He can turn angular momentum into linear momentum and vice-versa, as well as change its direction. Backlash accrual increases sublinearly with mass, and it is theorised that he would be able to redirect a moving commercial airplane and survive, though this has not been tested.
Backlash: Loss of coordination, making his movements look rubbery and "noodle-like". At high ends, hypermobility to the point of weakening of tendons, which may lead to lesions or ruptures.
