Ultra-Hand Return

Ultra-Hand Return is Wario's Defensive Power Shot in Mario Power Tennis. Wario flashes a big W, pulls out a strecher with a glove, and extends the strecher toward the ball. This causes the ball to cross over the net with a little power and is a straight shot. This gadget may also come from Bowser's training room, seen in the opening cinema of the game, where Bowser attempts to get Wario and Waluigi get better at tennis so they can beat the Mario brothers in a tennis match.
