If you activate the Power Shot Button, four red fists will appear, two on both sides of Asura and he will say "Come on" in a fast voice. The fists seem to be attached to the back of his head. However, these fists don't hurt the opponent in any way, even if he is really close to Asura.
Asura's Power Shot is the Red Fist Shot. Once he touches the ball to start his power up, he will fly towards his goal, staying at whatever altitude he was already at, and he says "Erie... Ra-ta-ta-ta-ta-ta-ta" in a very loud voice. Before the ball is shot, many (seemingly more than four) of his fists - which he gained after activating his Power Button Effect - will shoot out from him towards the defender's end of the goal. These fists will knock the defender back slightly, destroy any costumes he has on, and deal critical damage to the defender. The actual ball will be shot forward at the defender after all other fists are fired, and it will be shot high. If the defender does manage to block the ball, then he will be pounded to the ground by a huge red fist that comes from the top of the screen. This fist crushes the defender so that he is flattened to the ground. While crushed, the defender cannot move or deflect the ball; Asura can walk over him and the ball will roll straight over him as well. He (obviously) can't use his power shot or any other ability then.

Always watch a video when you play against Asura, so you can play against him for free. One of the achievements you have to fulfill is to beat him in Sudden Death. To win in a Sudden Death, walk forward, try to jump over Asura right from the start and then try to let him stay behind you (jumping is usually required to succeed) and dash him towards your goal. If you do this right, the ball will be untouched. Wait as time goes by, save your power shot. In Sudden Death itself, you have to wait until your opponent uses his power shot. Then power block it and score with your own power shot, to win the Sudden Death and Without conceding a goal achievements! For more tips, please visit our Characters Unlock Guide.
