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.
Also, 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.
In the Super Smash Bros. series, 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 shoot in an angle changing with the angle of the battlefield, while Luigi's shoots straight no matter what. Kirby can also use the Fireball move once he has sucked up Mario's power, but he shoots out green fireballs when he sucks up Luigi's power.
Appearance in Other Media
In the Club Nintendo comic "Super Mario: Verloren in der Zeit", Fire Mario uses a Fireball to defeat a Tyrannosaurus rex.
