Fire

Fire is a hazard in the Pikmin series. Most Pikmin types are not resistant to fire, and if they touch a fire source, the top of their stems will begin to burn up, they will run around in a panicked state, and if not saved, will eventually succumb and die. They can be saved by being whistled at. Red Pikmin and Bulbmin are completely immune to fire, making them necessary to handle obstacles or enemies that can produce or are on fire. Most enemies that utilize fire can leave flames in their wake.

Leaders are not normally invulnerable to fire hazards: they will take damage and be knocked back if they touch fire. However, by salvaging the Scorch Guard, they will be rendered completely immune to fire.

In Pikmin: Attack of the Breadbugs
Fire can be found mainly in the Inferno Territory of the Land of Wonders. Examples of enemies that use this hazard are Fiery Breadbugs and the Giant Toasty Breadbug. Fire can also be found around the Inferno Territory naturally.

In Pikmin: Wide World
Fire is a common hazard appearing in Pikmin: Wide World in a number of forms. Red Pikmin are resistant to fire and can extinguish a burning Pikmin. They can also stomp out flames to extinguish them prematurely. Any Pikmin, besides Red Pikmin, that touches fire will have the tip of their stem set ablaze, and begin running around until they eventually burn up and die. They can be saved by whistling them, having a Red Pikmin extinguish them, or having water touch them. Leaders that touch fire will take extreme damage from it for as long as they remain in contact with it unless they are wearing the Scorch Guard, which reduces fire damage and reduces it even further the more it is enhanced. Besides enemies, a few sources of fire exist. Incendiary bomb rocks create a fiery, but otherwise harmless, explosion when they detonate, which Red Pikmin can resist. They and other Pikmin types are still thrown back by the force generated by its explosion, however, and Pikmin that aren't Red Pikmin will be ignited as well. Fire geysers may either intermittently or perpetually expel jets of flame. Fire bramble gates are charred bramble gates that cannot be burned down and also contain fire geysers that perpetually expel jets of flame until the gate is taken down. Flames are patches of fire that harm mostly anything passing through them and eventually extinguish on their own. Ultra-hot spray, which can be made by harvesting the green berries of a Sunset Spiderwort, generates a temporary and damaging stream of fire originating from the front of the leader that used it. Wickweed buds can be used to ignite whatever they are used on. Various obstacles can be burned away, such as Asphyxiating Moldclumps, brambles, all types of bramble gates but the aforementioned type, burrow-nit nests, Jackwig hives, and webs. Although a type of bramble, Hydroe Brambles cannot be burned away. Water, forms of water such as rain droplets, and water-based enemies such as Goolixes and Rainwisps, can extinguish fire. Some enemies, such as Oily Groinks and Slick Dweevils, can worsen problems with flames because of the flammable oil they produce, which can be used against them.

Most enemies that utilize fire leave a patch of flames, either directly or indirectly. Blazing Dirigibugs regurgitate incendiary bomb rocks, which they toss down towards leaders and Pikmin when they come close. Charred Skitterleaves intermittently ignite themselves while they run around. Fiery Bulblaxes and Dwarf Fiery Bulblaxes are constantly cloaked in flames, cannot be fully extinguished by merely standing in water or being hit by it, and scatter flames all around themselves when they shake Pikmin off. Fiery Blowhogs and Fiery Blowlets can either spew a jet of fire or a volley of fireballs. Fiery Dweevils can release searing flames, but only do so in self-defense. Fiery Wollywogs and Young Fiery Wollywogs are perpetually cloaked in fire and cannot be fully extinguished by sitting in water or being hit by it. Fireflap Bulborbs are perpetually on fire and drop fiery projectiles while they fly around. Fireflinger Groinks launch volleys of fireballs from their mouth-cannon and are perpetually on fire. Firesnout Grubs expel jets of fire from their mouth. Flaming Mitites are perpetually on fire. Toasty Breadbugs and their giant counterpart are extremely hot to the touch. Incendiary Spectralids fly around, igniting themselves before swooping down at nearby Pikmin and leaders. Pyroclasmic Slooches are perpetually on fire. Telescoping Pumphogs and Stone Pumphogs can shoot either fire or water. The Ancient Bulblax has two Sunset Spiderworts on its back, which have a chance of releasing ultra-hot berries when it lands from jumping. The Emberglow Phosbat can scatter hot embers to defend itself with, which can set Pikmin on fire. The Grimacing Cremblub produces highly-flammable sweat when it needs to cool off. The Plasm Wraith can spit out a fire-based Elemental Plasm that sits over a flat pile of pink, burning slime. Lastly, the Titan Dweevil may, as one of its four hazard-based attacks, turn red before unleashing a massive cloud of fire.
