Fireball

A Fireball (also written as Fire Ball) is an orb of fire that can be used as a weapon. Typically, one can only shoot fireballs if he or she acquires a Fire Flower. However, some enemies can shoot fireballs without the use of a power-up. Additionally, Mario can train himself to shoot fireballs from his hand (without using a Fire Flower).

Fireballs appear in Super Mario 64 and Super Mario 64 DS. In Lethal Lava Land, a Fireball may spurt out of the Lava and leap in a straight line. Bowser also use fireball's as a way of attacking.

In the Mario Kart series, Fireballs are used as special weapons. In Super Mario Kart, Bowser would drop these items; touching them would make the driver spin out. Unlike other laid down items such as Banana Peels, however, they would move around a bit on the course. Fireballs reappeared in Mario Kart: Double Dash!!, where they are the special item of both Mario and Luigi. When the special item is used, five fireballs will be launched into the racetrack, hitting other drivers and causing their karts to spin-out. These fireballs are capable of ricocheting off walls. However, after a short amount of time, the launched fireballs will fizzle out.

In Mario Superstar Baseball, the Fireball is Mario and Luigi's special pitch. It, unlike most other pitches, goes in a straight line. The ball, as the name says, turns into an extremely hard to hit, fireball, red for Mario, and green for Luigi. And in Super Mario RPG: Legend of the Seven Stars, Fireball is a monster encountered in Booster's Tower in the Mine Room. Fireball looks like a Sparky or Pyrosphere, but blue in color.

Mario shoots red fireballs while Luigi shoots green ones. It is their normal B move, and it is used by Mario in all three games. Mario's Fireballs are affected by gravity (meaning they bounce against the ground), while Luigi's shoot straight no matter what, unless it ricochets off of something in front of Luigi. Kirby can also use the Fireball move once he has sucked up Mario or Luigi, and the color and performance of the Fireball are according to which Mario Brother he has sucked up.

Yoshi's Fireball
Yoshi too has fireball abilities. He uses this in Super Mario World and Super Mario 64 DS. In Super Mario World they can be spit by Yoshi after making him eat a Red Shell. These look like Podoboos and destroy most enemies. In Super Mario 64 DS, they are in a stream of Fire Breath and are Yoshi's Power Flower power. They are also found from Fire Chomps, Fire Guys and campfires. In Super Smash Bros. Brawl, Yoshi spits single fireballs in his Final Smash form.

Appearances in the Super Smash Bros. series
Fireball is Mario's standard Special Move across all three titles in the series, performed by pressing the B Button unless the player customizes the control scheme. The move allows Mario to shoot a red fireball from his hand in the style of Fire Mario from Super Mario Bros.. The fireballs are affected by gravity, bouncing against the ground until they burn out or hit an opponent. Fireball is a fire attack; opponents hit by the move suffer damage from the fire rather than the impact.
