The attack consists of Mario releasing a fireball from his hands to burn down opponents. Mario's Fireball has a reddish-orange coloration.
In the original Super Smash Flash, Mario's Fireball is not affected by gravity and travels in a straight horizontal line until it disappears out of screen; it is able to strike numerous opponents as a result of this, the distance it covers is also quite ample. All these traits are also shared with Luigi's Fireball variant.
For the reboot, Super Smash Flash 2, Mario's Fireball now works more akin to its Super Smash Bros. counterparts: it is affected by gravity and continues to bounce forward until it hits an opponent, doing 5% of damage, or bounces back from a wall, before eventually fizzling out should it not hit anything. Its distance is also reduced.
Fireballs first appear in the arcade game Mario Bros. as an obstacle to evade by Mario or Luigi. It came in two variants: red and green. a red Fireball moves in random patterns affected by gravity while a green one moves in a straight line from one side to another, unaffected by gravity. However, the first time Mario is able to shoot Fireballs himself is in the NES game, Super Mario Bros., done after obtaining a Fire Flower, which can be used to take down every enemy in the game (except for the Buzzy Beetle which is resilient to Fireballs). In SSF2, and unlike SSF, Mario's Fireball attributes seem to be based on the red Fireball obstacle from Mario Bros.. It should also be noted that on its original appearance, a Fireball does not bounce from walls, it immediately disappears after colliding with one, this does not happen in any of the SSF games.
