Fire Bar

Fire Bars (also parsed as Fire-Bars , fire bars or firebars ) are rotating bars made of fireballs first appearing in Super Mario Bros. Fire Bars were originally created as an obstacle for The Legend of Zelda series, but ended up being used for the Mario franchise first. They are found in numerous titles and generally act as obstacles in castles and fortresses.

Fire Bars were also given notable appearances in certain castles of Super Mario World 2: Yoshi's Island, which depicted them as swinging three-dimensionally. A three-dimensional Fire Bar depicted with eyes also appeared in Waluigi Stadium and Bowser's Castle course of Mario Kart: Double Dash!!.

Super Mario Bros.
Fire-Bars make their debut in Super Mario Bros. They are not a living enemy and function more as an obstacle as they rotate around a block in a clockwise or counter-clockwise direction. They often appear on the ceiling and floors of castles, or, more rarely, in underwater sections. The first level in which they appear is World 1-4. If Mario or Luigi makes contact with one, he will take damage from the fire. In later games, they are replaced with similar-acting obstacles, such as Roto-discs and Spinners. The first Fire-Bar in World 5-4 is composed of 12 fireballs, as opposed to the normal six fireball length. If the player beats the game and restarts on Hard Mode, Fire-Bars will appear in all possible locations in castles.

Super Mario Bros.: The Lost Levels
Fire-Bars also appear in Super Mario Bros.: The Lost Levels, working as they do in Super Mario Bros.. Unlike in that game, longer Fire-Bars are more common.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64, they appear for the first time in full 3D. They only appear in Lethal Lava Land. Unlike Fire-Bars' 2D appearances, here they spin horizontally. Also different from their 2D appearances, there can be more than one Fire-Bar rotating on the same axis.

Super Mario Advance 4: Super Mario Bros. 3
While they do not appear in the main game, Fire Bars do appear in certain World-e levels in Super Mario Advance 4: Super Mario Bros. 3, more specifically in Swinging Bars of Doom, An Aqueous Adventure and Classic World 1-4. They exist in two variations: either with one Fire Bar around the axis, or with two Fire Bars, both variations being of various lengths. In An Aqueous Adventure, where most of them are found underwater, there is even one with two pairs of Fire Bars rotating in opposite directions.

New Super Mario Bros.
In New Super Mario Bros., Fire Bars first appear in World 6-4. They also appear in the second tower of World 8, and a lone one appears in Bowser's Castle. Here they act just like they do in Super Mario Bros., but are found more commonly more on the ceiling and floors.

Super Mario Galaxy
In Super Mario Galaxy, they appear as obstacles in a number of different galaxies, including the Sling Pod Galaxy, the Toy Time Galaxy, Bowser's Star Reactor, and Bowser's Galaxy Reactor. They function the same way as in Super Mario 64.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Fire Bars only appear in, and , and are often used to guard Star Coins. A double Fire Bar also appears in the tower. In the castle, they are mainly seen in the first room, and only two are seen in the second room.

Super Mario Galaxy 2
In Super Mario Galaxy 2, the Fire Bars' function is the same as in Super Mario Galaxy. They mainly appear in Bowser Jr.'s Fiery Flotilla, Bowser's Gravity Gauntlet, the Slipsand Galaxy, and Bowser's Galaxy Generator. It is also of note that rotating Fire Bars are used during the boss battle with Bowser Jr.'s Boomsday Machine in his Boom Bunker, where they are integrated directly into the Boomsday Machine.

Super Mario 3D Land
Fire Bars reappear in Super Mario 3D Land. Here, they appear in most castles and World 8-6. As with all 3D installments of the Super Mario series, Fire Bars spin horizontally. They cannot be defeated. The game introduces Spike Bars, which are Fire Bars with spiked balls in place of fireballs.

New Super Mario Bros. 2
Fire Bars appear again in New Super Mario Bros. 2. They have the same pattern from both predecessors and may also sometimes hide Star Coins. Fire Bars only seem to be one fireball longer then past games. They mostly appear in castle levels and some World 6 levels.

New Super Mario Bros. U
Fire Bars reappear in New Super Mario Bros. U, where they appear in Screwtop Tower and Slide Lift Tower. Huge Fire Bars also debut in this game, first appearing in Slide Lift Tower. Huge Fire Bars also have a whole level based around them in Superstar Road called Fire Bar Cliffs, which is home to many Huge Fire Bars.

Super Mario 3D World
Fire Bars appear in Super Mario 3D World. This time, some of them rotate around Brick Blocks and ? Blocks. Spike Bars also return with a new appearance.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Fire Bars reappear as a course element in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2. Their length and direction can be adjusted. The center block has a new sprite in the Super Mario Bros. theme, and new sprites were made for the Super Mario Bros. 3 and Super Mario World styles.

The Legend of Zelda series
Fire bars, or Guruguru bars , appear in The Legend of Zelda: A Link to the Past, The Legend of Zelda: Four Swords Adventures, The Legend of Zelda: The Minish Cap, The Legend of Zelda: Phantom Hourglass, The Legend of Zelda: Spirit Tracks, The Legend of Zelda: A Link Between Worlds, and The Legend of Zelda: Tri Force Heroes. As in the Mario franchise, they rotate continuously and are indestructible. However, some games play with this concept, such as switches that change the direction of the bar's rotation. While 2D titles depict the center as a block, 3D titles redesign the center.

Yoshi's Island series
Fire-Bars appear in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. They appear in certain forts and castles. They are usually depicted as swinging three-dimensionally. They also reappear in Yoshi's Island DS.

Fire Bars make several appearances in the Mario Kart series. They make their first appearance in Mario Kart: Double Dash!!, where they appear on the Waluigi Stadium, Wario Colosseum and Bowser's Castle courses. Fire Bars later return in Mario Kart DS, in the Wario Stadium course. Here the Fire Bars have three bars coming off of an eyed central cog. Fire Bars reappear once again in Mario Kart Wii, in the Waluigi Stadium retro course and the game's Bowser's Castle, although in this instance, there are Lava Bubbles at the center. They are also called Podoboo Cogs, keeping consistency with their appearance. Fire Bars make reappearances in Mario Kart 8's Bowser's Castle course and in the DS Wario Stadium retro course. Here the Fire Bars have the same forms as in Mario Kart DS. Similar obstacles, rings of fireballs called Fire Chains, appear in a few of these titles as well.

Paper Mario
In Paper Mario, the Fire Bars reappear in Koopa Bros. Fortress and Mt. Lavalava; this time they swing sideways. They also swing either clockwise or counter-clockwise. If Mario touches one, he loses some HP, but if Mario's partner touches one, nothing happens. Jumping over one of these Fire Bars causes it to swing faster. If Mario dodges one ten times, it will vanish and drop a number of coins. This is the first appearance in which Fire Bars can be destroyed.

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, they reappear in Bowser's third platform level. Here, they can be defeated by Bowser's fire breath. If Bowser come in contact with the fireballs, they can either decrease his size or defeat him (if he is tiny). They also appear in the Palace of Shadow and have the same behavior as they do in Paper Mario.

Super Paper Mario
Fire Bars reappear in Super Paper Mario. In the game, they act in a similar fashion as in Super Mario Bros. and appear in Chapter 1-4 and 8-2. Mario can flip into 3-D mode to avoid the Fire Bars.

Wario: Master of Disguise
Fire Bars appear as obstacles inside Sweatmore Peak in Wario: Master of Disguise. They consist of several small fireballs which rotate around a larger fireball.

Super Smash Bros. series
In Super Smash Bros. for Nintendo 3DS / Wii U, Fire Bars appear as an item. Once picked up, characters can attack others by swinging them, similar to the Beam Sword, although it is fairly powerful. However, every two hits from a Fire Bar causes it to lose a fireball, including blocked hits, shortening it in range. The fireballs closer to the base, however, deal more damage. Fire Bars reappear as items in Super Smash Bros. Ultimate.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, Fire Bars appear in the Trio Whirligig minigame in the Arcade as obstacles. They are made up of two to seven bars, and touching one causes the minigame to end.
