Wave zap
The wave zap is a recovery technique used for Lucas in Super Smash Bros. Brawl. It can be used by combining the zap jump and Magnet Pull techniques. To perform the technique, use a B-sticked PK Fire by pushing the C-stick in the opposite direction that Lucas is facing while pressing B and double jumping at the same time. Then, immediately use PSI Magnet. Lucas will shoot backwards a huge distance with a huge vertical jump. This can be combined with Reverse Magnet Pulling to go forward as well. It is possible to do a technique resembling this by doing a normal Zap Jump, but also changing the angle of the jump.
Alternatively, an easier method can be used on a B-sticked Gamecube Controller with Y or X set to jump. In midair, Press X/Y and (with the timing of a normal Zap Jump) immediately after push the C-stick and Analog stick in opposite directions (left and right, you cannot use up and/or down). Then push the C-stick down to do a Magnet Pull. To recover to the right, push the Analog stick to the left (you will still need to push the C-stick in the opposite direction). To recover to the left, push the Analog stick to the right.
This move can be used to KO after a fully charged PK Freeze.
