Super Jump Punch

The Super Jump Punch (スーパージャンプパンチ, Super Jump Punch) is Mario, Dr. Mario, Luigi, and Waluigi's up special move.

Mario
Mario's version of the Super Jump Punch has him jump diagonally upward. If he strikes an opponent during the jump, he deals several hits while coins fly out of the enemy (which is accompanied by the coin sound effect from the official Mario games).

Dr. Mario
Dr. Mario's version of Super Jump Punch, while behaving in a similar way to Mario's, has a few traits that distinguish it from its normal counterpart; there are two hits, with the first hit sending opponents into the second hit, which is an explosion that launches opponents. As such, it is stronger than his normal self's version.

Luigi
Luigi's Super Jump Punch, contrasting from his brother, does not deal multiple hits. Most of the move consists of a large sourspot that deals 1% damage and almost nonexistent knockback, while producing a single coin. However, if the move connects with fighters right next to Luigi at the very beginning, the move deals drastically increased knockback and electric damage to opponents hit. Additionally, the move sends Luigi straight upward, with low horizontal drift after the rise, forcing Luigi rely on Green Missile and Luigi Cyclone for horizontal recovery.

Waluigi
Waluigi's Super Jump Punch, much like Luigi's, sends him straight upward, and has a sweetspot when the move connects in the first few frames, though the descending portion is very different: as he descends, Waluigi spins, surrounding himself in a light blue vortex. This vortex has an active hitbox that deals multiple hits, and this descent gives Waluigi full access to horizontal control.

Origin
The Super Jump Punch is based on the simplest technique in the Mario series - the jump. This allows Mario and Luigi cross gaps, defeat enemies, and break bricks.

The move in particular is based on how Mario and Luigi can jump to break certain blocks to reveal coins, the main currency of the Mushroom Kingdom, by holding their fists upward to punch. These coins can be seen when Mario and Luigi (sourspot only) uses the attack on a foe. These coins use the design from Super Mario 64, and are accompanied by a sound effect that resembles the "coin get" sound effect from Super Mario Bros.
