Fireball is Mario's neutral special move in Super Smash Bros. Ultra Lucha.
When the special button is pressed, Mario shoots a red fireball from his right hand. The fireball goes forwards bouncing in the ground, and is really quick. It deals 5% damage. It is affected by gravity, so if Mario shoots in the air, the fireball will fall at an angle.
In almost all Mario platformer games, Mario (and other characters such as Luigi, Peach, Toad and Rosalina) can obtain Fire Flowers from ? blocks. Fire Flowers give the character the power to shoot fireballs. The character loses the power when hit by an enemy, or, in the case of the Galaxy games, when time runs out.
First Appearance of move: Super Mario Bros. (NES, 1985)
