Strong Guy has the ability to absorb kinetic energy, using it to increase his physical strength to superhuman levels. This causes his upper body to swell dangerously, so he cannot keep it up for long (he uses humor to distract from the pain). When absorbing energy, any damage he would take grants him an Attack token instead. This allows him to build up devastating counterattacks. However, if he ever accumulates too many tokens, he’s immediately KO’d.
