Super Jump Punch is an attack that can be executed in all three Super Smash Bros. video games. The characters that perform this attack include Mario, Luigi, and Dr. Mario. You're able to do a Super Jump Punch after tilting the joystick upwards then pressing B, which will cause one of the three aforementioned character to thrust their fists up and jump high. If Mario happens to attack one of his opponents when doing this, then coins will spew out of him. This is basically a recovery move, though it can also be used to deliver damage.
Luigi's Super Jump Punch acts a bit differently. Rather than jumping high up and moving a little in the direction he's looking in, he essentially just jumps straight up, which overall is a poorer recovery attack. Also, if he attacks an opponent while doing this, only one coin will be ejected rather than a multitude of them. Nevertheless, the attack can be much more devastating if performed correctly (you execute the move when you are standing in the same place as the other character) - if you do, the enemy will be engulfed in flames, with the same noise the home-run bat makes, and they would receive up to 25% damage, 24% more than usual!
