Fire Flower

The Fire Flower (ファイアフラワー,　Faia Furawā) is a power-up in the Mario series that grants the ability to shoot fireballs and is also a item in Super Smash Flash.

In Super Smash Flash
Like the Super Smash Bros. series, in Super Smash Flash the Fire Flower emits a steady stream of fire and is held as an item rather than a power-up. Also, once it goes out, it completely disappears, unlike its appearance in the SSB game where one can throw the flower for fiery damage.

Origin
The Fire Flower is one of the power-ups that debuted in the 1985 NES game, Super Mario Bros., and has become one of the most recurring power-ups in the Mario series. In the platformer game it appears, when Mario, Luigi or any character pick up a Fire Flower, they would gain the ability to shoot bouncing fireballs at enemies, gaining their Fire form. The color of their clothing would change as well, normally, being white with the corresponding character color, such as Mario's clothes changing to red and white.

The Fire Flower is also a recurring item is Mario spin-offs, such as Mario Kart and, as with the platformer games, it grants the ability to shoot fireballs at other drivers for a brief period of time, the flower is also the emblem of the Flower Cup.

Trivia.

 * The Fire Flower is one of many items that at some point were confirmed to be in SSF2 but whose current status is unclear.
 * The Fire Flower had already made some appearances in SSF2 where it was briefly seen whenever Mario used his Final Smash to turn into Fire Mario, originally, two appeared but was later changed to one only. This is no longer seen because Mario's Final Smash was changed to the Mario Finale.
