Piston Punch

Piston Punch is the Mii Brawler's third up special move that can be used in Super Smash Bros. for Nintendo 3DS / Wii U. The move involves the Mii rising into the air with a series of punches, similar to Little Mac's Rising Uppercut, and dealing multiple hits to any opponents caught in the attack.

The other up special moves available to the Mii Brawler are Soaring Axe Kick as the first custom option and Helicopter Kick as the second.
