Mr. Gannosuke
The Gannosuke Clutch has an attacking wrestler facing the opponent, grabbing their arm, twisting it into a modified hammerlock and then performing a front somersault while holding the trapped arm in place as well as legsweeping the opponent's near leg, rolling the opponent backwards while the attacking wrestler keeps the hammerlock applied while also holding the opponent's near leg down with their own leg. This move is also known as an arm trap somersault cradle. This was innovated and popularized by Mr. Gannosuke, who named it after himself.
