Xavier starts by snapping his fingers, freezing time. Xavier dashes foward and punches his frozen oppent rapidly. Xavier then appears behind his foe and kicks them the other direction. Xavier teleports back to his starting place and kicks his foe into the air. Xavier then appears in the air and double axe handles his opponent back to there starting place. Xavier teleports back to where he once and snaps, unfreezing time.

Xavier first used this move while in the tournament once he battled the school bully: Yuuta.
