Zap Jump is an advanced technique used for Lucas (SSBB). This technique can nearly double Lucas' Double Jump.
To execute this move, the player must use PK Fire immediately after initiating the second jump. It is easiest to use this technique on the Gamecube controller by setting another button on the opposite side of the controller to quickly use both buttons nearly simultaneously, such as X or Y to jump and the L trigger to special attack.
can be done by setting c stick to special right snd c stick foward after jumping
