Fire

"A flaming ability that burns white hot! Light the fuse, roll into a fireball, and scorch through the air with a bang. Embrace the blistering flames of Fireball Inferno!"

- Fire's Flavor Text

Fire is one of Kirby's basic Copy Abilities. It was one of the first, debuting in Kirby's Adventure alongside other iconic abilities like Beam and Ice.

General Information
The ability is most often confused with Burning. Not only do they revolve around the same element, but Burning's main function, a charge forward whilst covered in flames, is oftentimes an attack used by the Fire ability itself.

Also adding to the confusion is the fact that when Rick acquired the Burning ability in Kirby's Dream Land 2 and Kirby's Dream Land 3, he would blow out fire just like the Fire ability. The attacks obtained when mixing abilities with it in Kirby 64: The Crystal Shards (in which it has the same properties as Burning) were based more on Fire as well.

This ability's primary attack is spewing fire, setting any nearby enemy ablaze. But in more current games, Kirby has also mastered other techniques, such as covering himself in fire as means to severely damage enemies.

In Kirby: Right Back at Ya!
Kirby has obtained Fire in many episodes of Kirby: Right Back at Ya!. It is the most common ability used in the anime, with nine appearances in total. The attack that Kirby uses depends on what he swallowed to get the ability. For example, torches give him his standard Fire breathing attack, while inhaling fireworks allows him to spit fireworks back, like the Fireworks Combo Ability from Kirby 64: The Crystal Shards. In the transformation sequence,the green gem forms in the crown and catches fire. Fire Kirby also makes an appearance in the 3-D short "Kirby 3D". It is also notable for being the first seen in the anime as well.

Super Smash Bros. series
Fire Kirby appears in both Super Smash Bros. Melee and Super Smash Bros. Brawl as one of the collectible trophy. Inhaling Bowser will allow Kirby to blow fire, and his Bowser hat is reminiscent of the Fire Ability hats posture when breathing the fire is the same. The same thing happens when he inhales Charizard. In Melee, Kirby's dash attack is also the Burning Attack, only it cannot rush through the air if used over an edge (thus is affected by gravity) and Kirby will still fall downwards during the attack if so.

"When Kirby swallows a fire-wielding enemy, he transforms into Fire Kirby. Not only does he breathe fire in this form, but he can also sprout flames on his entire body and damage enemies by crashing into them. Fire Kirby wears the bright red headdress of his enemy Burning Leo. The hat turns into a helpful weapon when thrown."

- Trophy description

"Kirby when he inhales an enemy who uses fire. Shooting fire from his mouth, Fire Kirby can cook enemies from afar. This ability also allows Kirby to light explosive blocks, fuses, and so on. In Kirby Super Star and Kirby & The Amazing Mirror, Fire Kirby can roll his burning body into enemies as an attack move."

Trivia

 * In Kirby Super Star, the ability cap's design was shared with Ice and Plasma, so the flames at the top were a solid decoration. This gives it the appearance of Burning Leo or, to a lesser extent, Hot Head's original design.
 * While the GBA remake of Kirby's Adventure was the first appearance of the new design, Kirby Air Ride reused the original design from Kirby Super Star.
 * The canceled Kirby GCN also would have given subtle changes to the newer design, similar to Kirby's Return to Dream Land except the gem would have been cut as a hexagon. Incidentally, the unused Kirby GCN version of this design is seen as a Trophy in Super Smash Bros. Brawl.
 * In Kirby: Squeak Squad, Fire could be used to burn away foliage, clouds, or ice cubes, thus altering the landscape around Kirby, and sometimes revealing hidden items or pathways.
 * This is one of the only four abilities in Kirby: Triple Deluxe that can break ice blocks. The others are Hammer, Fighter, and Circus.
