Fire Mario

Fire Mario and Fire Luigi are the forms Mario and Luigi take after powering up with a Fire Flower. The form was first introduced in Super Mario Bros., and is one of the few forms to appear in more than one game. Wario also made use of a Fire Flower to become Fire Wario in a last-ditch attempt to defeat Mario in Super Mario Land 2: 6 Golden Coins. Strangely, the fireballs produced by these abilities can be thrown underwater. In New Super Mario Bros. Wii, Yellow Toad and Blue Toad can turn into Fire Yellow Toad or Fire Blue Toad. Fire Mario is one of the many ways, possibly safest along throwing a Shell, under the power of a Starman or being Hammer Mario, to take out Hammer Bros. and their relatives, just by throwing fireballs at them. Hammer Mario is a Hammer Bro. version of Fire Mario, except the hammers can take out enemies that fireballs can't. This form's polar opposite is Ice Mario. In Super Smash Bros. Brawl, Mario does not however, need a fire flower to get his fire powers. For other characters, however, there is a fire flower power-up that will give him/her temporary fire powers.

Super Mario Bros.
In the form's first appearance, in Super Mario Bros. (and later in the Japan-only sequel, Super Mario Bros.: The Lost Levels), both Mario and Luigi's hats and overalls would change to white and their shirts would change to red. In the remake, Super Mario Bros. Deluxe, Fire Luigi kept the white cap and overalls, but his shirt turned green (same as Luigi's regular color-sceme in the original version), while in his regular form he wore a green cap, green overalls and a brown shirt. Mario and Luigi's form with a Fire Flower is still the same in the Japan release, Super Mario Bros.: The Lost Levels

They became Fire Mario or Fire Luigi after coming in contact with a Fire Flower, thus gaining the ability to throw fireballs. However, Mario (or Luigi) would revert back to Small Mario (or Small Luigi) if they were to take damage. The fireballs would bounce along the ground and could defeat almost all enemies, including otherwise unbeatable ones such as Spinies; they were also Mario and Luigi's only means of offense in underwater stages. Interestingly, using fireballs to defeat Bowser was the only method that yielded points.

Super Mario Bros. 3
After a brief absence from Super Mario Bros. 2, Fire Mario returned in Super Mario Bros. 3 with one slight change in that Mario and Luigi would both change to an orange colorization instead of their clothing changing. However, this may be because of limitations on the NES, as official artwork and remakes of the game depict Mario with red overalls and a white hat and shirt. This was the first game where, if damage was taken, they would only revert to their super form.

Super Mario World
Fire Mario's appearance in Super Mario World was the first time he appeared in-game as depicted in artwork. It was also the first time that Fire Luigi had a different colorization from Fire Mario. They retained all the skills found in earlier releases, with the added ability to throw two fireballs at either side of themselves when using the new Spin Jump move. In the Game Boy Advance remake, if they got damaged, they would change back to their super form, like in Super Mario Bros. 3.

New Super Mario Bros.
After the release of Super Mario Land 2: 6 Golden Coins, Fire Mario did not make another appearance for fourteen years, finally returning in New Super Mario Bros.. Fire Mario and Fire Luigi function exactly the same as they did in the earlier Super Mario Bros. titles; however, they were no longer Mario's highest form attainable. Many new power-ups were introduced, and would simply over-ride the Fire form when their items were encountered and utilized. However, when Mario or Luigi gets hit, they will become Super Mario just as in any other game.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Fire Mario (or Fire Luigi) has the same abilities of the predecessor. Also, Yellow Toad and Blue Toad can use the Fire Flower Power-Up. A form similar to that of Fire Mario has appeared in New Super Mario Bros. Wii; Ice Mario.

Super Mario Galaxy
Fire Mario made its 3D platformer debut in Super Mario Galaxy, found in the Freezeflame Galaxy, Dusty Dune Galaxy and Deep Dark Galaxy, with a few changes, such as the form being time-limited instead of being lost by taking damage (which meant Mario could now be hit and still retain this form), the fireballs could no longer be used underwater and Mario wouldn't be able to Spin until the form wore off. Fire Luigi also appears when using a Fire Flower as Luigi.

Super Mario Galaxy 2
Fire Mario (and Fire Luigi) re-appears from Super Mario Galaxy in Super Mario Galaxy 2. Mario can turn into this form in the Rightside Down Galaxy, Freezy Flake Galaxy, Slipsand Galaxy, Upside Dizzy Galaxy and Battle Belt Galaxy. Fire Mario must be used to clear the missions "The Great Crate Incinerator" in the Rightside Down Galaxy, and "Burning Upside Dizzy" in the Upside Dizzy Galaxy, where he must burn all the crates in the time limit.

Super Mario 3D Land
In Super Mario 3D Land, Fire Mario returns once more as one of the power-ups Mario can obtain. Unlike the other 3D titles featuring the form, Super Mario Galaxy and its sequel, Fire Mario does not have a time limit in Super Mario 3D Land, only being lost when Mario is hit, like in the Mario side-scrollers.

Super Mario Land
While Fire Mario didn't appear in Super Mario Land, a form very similar to it, known as Superball Mario, made its first and only appearance.

Super Mario Land 2: 6 Golden Coins
In Super Mario Land 2: 6 Golden Coins, the form's appearance was changed again, this time only simply adding a feather to the top of Mario's cap (most likely due to the Game Boy's inability to display the color difference). Additionally, in the final phase in the battle with Mario, Wario used a Fire Flower to become Fire Wario (again, by adding a feather to his cap) and resorted to fighting solely by throwing fireballs. He was still defeated, causing him to revert to Tiny Wario and run away.

Mario and Sonic at the Olympic Winter Games
Though Fire Mario doesn't appear in Mario and Sonic at the Olympic Winter Games, players can purchase a Fire Mario suit for their Miis when buying a random lottery ticket at the Secret Shop.

The Super Mario Bros. Super Show!
In The Super Mario Bros. Super Show!, this form was called Super Mario or Super Luigi, due to their actual Super forms being their regular forms. some of the differences from the games where that the form wasn't just achieved with Fire Flowers, but also Stars, a Magic Pendant and at one point, a shock from a high voltage. In some instances, the form itself was referred to as Fire Power, a name which carried over into the two following series. As well as granting the Mario Bros. with the ability to shoot fireballs from their fingers, the form endowed them with extra strength, speed and even the ability to fly. Toad also used this form in the episode "The Fire of Hercufleas". Princess Toadstool turned into this form in "The Trojan Koopa", although she did not shoot fire.

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3, the form was changed to match its appearance in Super Mario Bros. 3: Mario had colorization and could only throw fireballs. Bowser, with the help from the Power Pendant, could also use this form in the episode "Super Koopa".

Super Mario World
In the Super Mario World cartoon the forms appearance was changed again to match its appearance in Super Mario World. However, the form had very limited screen time in this series; it was only featured in the episodes "Send in the Clown" and "King Scoopa Koopa".

Nintendo Comics System
Strangely, the Nintendo Comics System almost never featured either form. The only appearance was in the prologue short, "The Legend"; in one panel, Luigi was shown throwing fireballs at some Beezos, but he was wearing his regular outfit rather than his Fire Luigi suit.

 * At Nintendo World, during the time period when people could interact with Mario or Wario, if someone asks Mario a question about his attire while being Fire Mario, he claims that the red jumpsuit and white shirt are fire resistance.
 * Despite this, Fire Mario is not invincible to lava, and therefore, it will damage him normally if touched.
