In Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, Dr. Mario's Super Jump Punch only strikes with a single hit, and gives him less distance than Mario's version. Dr. Mario's Super Jump Punch is also stronger than Mario's version, dealing much higher knockback.
Luigi's performance of this move is similar to Mario's, but with some differences: Luigi's version gives him high vertical distance but no horizontal distance whatsoever; and it deals extremely low damage (1-3%) in most scenarios. However, if it is performed right next to an enemy, Luigi instead performs the Fire Jump Punch and deals around 25% damage with high knockback to the enemy.
In Super Smash Bros. for Nintendo 3DS / Wii U, the Super Jump Punch can be customized, where Mario and Dr. Mario share their custom variants, while Luigi has his own unique custom variants. One of Mario's and Dr. Mario's custom variants is Super Jump, which increases the vertical distance but does not deal any damage, while the other one is Explosive Punch, known as Ol' One-Two (named The Ol' One-Two in British English) for Dr. Mario, which produces fire and explosive damage. Luigi's custom variants are Fiery Jump Punch and Burial Header. The Fiery Jump Punch makes it easier to perform the Fire Jump Punch move, while the Burial Header damages grounded opponents while falling.
