Fire Mario

Fire Mario and Fire Luigi (originally known as Firey Mario) 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. 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. In New Super Mario Bros. U, Miis can become Fire Miis as well. 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.

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 change to white and their shirts change to red. In the remake, Super Mario Bros. Deluxe, Fire Luigi keeps the white cap and overalls, but his shirt turns green (same as Luigi's regular color-sceme in the original version), while in his regular form he wears 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) revert back to Small Mario (or Small Luigi) if they take damage. The fireballs bounce along the ground and can defeat almost all enemies, including otherwise unbeatable ones such as Spinies; they are also Mario and Luigi's only means of attack in underwater stages. Using fireballs to defeat Bowser is the only method that yields 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 Super Mario World, enemies are turned into coins if they are defeated. However, if the coin is not collected the enemies will reappear if Mario leaves and revisits the area. In the Game Boy Advance remake, if Fire Mario/Luigi got damaged, he 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. Much like in Super Mario World, enemies that are destroyed with Fireballs will turn into coins.

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.

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. Thier appearances make the spots, vest, and pants red, and the white is the cloror of what their spots used to be. A form similar to that of Fire Mario has appeared in New Super Mario Bros. Wii; Ice Mario.

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 classic Mario side-scrollers.

New Super Mario Bros. 2
In New Super Mario Bros. 2, the Fire Flower is one of the power-ups that Mario can use in his new game, retaining the same effects as in previous games. Additionally, when the player beats a stage as Gold Mario, he or she is turned into Fire Mario.

New Super Mario Bros. U
In New Super Mario Bros. U, Fire Mario reappears, once again functioning as it did in previous games. Of note is that Miis are now capable of using Fire Flowers to become Fire Miis.

Super Mario 3D World
In the upcoming Super Mario 3D World, Fire Mario returns, functioning like previous games. Peach now can use the Fire form. Her appearance is based on her sprite from Super Mario Bros. with her hair tied back like in Super Mario Sunshine.

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 Golf series
Although the powerup itself is not present, Mario and Baby Mario have an alternate color scheme that resembles the outfit.

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.

Mario Tennis Open
In Mario Tennis Open, there is a Fire Mario suit that can be unlocked by turning two characters into star characters.

Paper Mario: Sticker Star
Paper Mario: Sticker Star is the first appearance of Mario's fire transformation in a Paper Mario game. Whenever a Fire Flower sticker or either of its variants are used, Mario is transformed into Fire Mario to attack. He attacks all enemies on-screen by hurling one fireball at each of them before reverting back to his normal state.

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 were that the form wasn't just achieved with Fire Flowers unlike in the video games, 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 an orange colorization (like his SMB3 sprite). 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 and the modern appearance. 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
The Nintendo Comics System only features the form in the prologue short, "The Legend"; in one panel, Luigi throws fireballs at some Beezos, but he is wearing his regular outfit rather than his Fire Luigi suit.

Trivia

 * Mario has previously been able to use fire without being Fire Mario, though these instances were when power-ups didn't appear, such as Super Mario RPG: Legend of the Seven Stars or the Super Smash Bros. games. Also, Mario could create a fireball by using the acquired Firebrand skill in Mario & Luigi: Superstar Saga.
 * Fire Mario and Fire Luigi (pictured) appear as alternate colors for Mario and Luigi in Super Smash Bros. Brawl.
 * Super Mario Galaxy and Super Mario Galaxy 2 are the only games where the Fire Flower is lost after it wears off instead of after taking damage.
 * 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 resistant.
 * Fire Yellow Toad's color scheme resembles those of the Mega Mushroom. Fire Blue Toad uses this color scheme in Super Mario 3D World.
 * In Nintendo Land, if a red or green Mii plays Yoshi's Fruit Cart, they will resemble Fire Mario and Fire Luigi without hats.
