Super Jump Punch
The Super Jump Punch is a jumping move Mario, Luigi and Dr. Mario can perform in the Super Smash Bros. series. It was executed by pressing B while holding the control stick upwards. When Luigi was performing it, he was jumping forward like Mario in the original SSB, but he jumped straight up in Melee. He could recover using the Green Missile attack. When either of the Marios perform the attack, coins would fly out of the enemy, and the foe would receive about 10 % damage. Dr. Mario's version of the attack is the exact same as Mario's, only more powerful. According to screenshots, Mario and Luigi will use Super Jump Punch yet again in Super Smash Bros. Brawl.
When Luigi performs it, only one coin flies out of the enemy. But, if done correctly, the enemy would be cloaked in fire and would receive up to 25 % damage. However, Luigi must be positioned right in front of his enemy for this Super Jump Punch to work, otherwise it results in 1 % damage.
