When performed, Mario would take out and absorb the power of a Fire Flower, transforming him into Fire Mario. This improved his mobility, and infused his attacks with fire, making them stronger and faster.
Moves forwards slightly, then leaps off the ground while punching upwards. After reaching the peak of his jump, Mario will spin in place several times before plummeting downwards and finally crashing into the ground. Mario can be steered sideways, as well as cancel the move into an aerial attack or a special move during Flaming Jump Punch's entire duration.
Fire Mario is a form in the Mario series that Mario takes after obtaining a Fire Flower. Originating in the original Super Mario Bros., this form is the most common of all of Mario's powered-up forms throughout the series, appearing in almost every Mario game featuring power-ups. It most often recolors Mario's clothing to white with red overalls and gives him the power to shoot fireballs. Contrary to its use in SSF2, the form generally has little other use beyond this, though it does grant Mario strength, speed, and even flight in The Super Mario Bros. Super Show!.

Prior to v0.5a of the SSF2 Demo, Fire Mario used a completely different set of sprites and a much different moveset. His standard attack was a seven-hit beat-down and all of his special moves were completely different. The Super Fireball did not release the Mario Finale at full charge (though he released a mini-version of the attack), his side special move was Heat Shield rather than Golden Cape, and his down special move was Fire Mario Eruption rather than Firewall Tornado.
Out of all of the removed content throughout the SSF2 demos, Fire Mario has proven to be one of the most controversial. Fans commonly request its return, complaining that its absence detracts from SSF2's individual identity and makes Mario too much like a clone of his official Super Smash Bros. appearances. Despite these complaints, the developers have stated that it will not be returning.
