Tenshin Nasukawa isn’t a name familiar to many people, but in the MMA world he’s making monumental waves. The 19-year-old phenom has become the face of major Japanese promotion Rizin Fighting Federation after starting his kickboxing career at 13 years old. His latest victory saw him deliver a breathtaking maneuver that left his opponent stunned on the canvas. The move is known as “rolling thunder,” and normally fighters would deliver the blow with their outside foot. Nasukawa, however, stunned his opponent by tweaking the move and instead used his inside leg, which landed flush on his target.
