 Thunderclap's piston-like metal gloves are connected to a hydraulic device in the back of his suit which uses potential and kinetic energy that allow the gloves to collide together faster than the speed of sound.The resulting sonic boom (approximately 2000 decibels) is released outwards in a destructive energy sphere which strikes any matter with which it comes into contact with tremendous impact.The sonic boom also has the tendency to temporarily deafen and disorientate anyone in the immediate area.
