If you mean the F-Zero vehicle then go to Fireball (F-Zero).
A Fireball 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).
