The Fire-type is a very balanced type overall in Pokémon. One of the Starter Types in every generation, it features a wide move pool and a consistent representation in nearly every region except for Sinnoh. It has three major weaknesses, Water, Rock, and Ground, although most Fire-type Pokémon can learn Solar Beam to counter them all. They're also super effective against the extremely powerful Steel-type, making them extra valuable.
Four Gym Leaders and two Elite Four members are Fire-type specialists, giving the typing a strong showing in all generations except for two and seven. Constantly paired with the Fighting-type, Fire has some of the fiercest and most intimidating Pokémon in the game, most of which are widely known.
Talonflame
When Generation VI first came out, Talonflame was the Fire-type to have. Not only was Fletchling accessible absurdly early but it also reached its final evolution at the very logical level of 35. What truly made Talonflame special, though, was its signature ability, Gale Wings, which gave priority to all Flying-type moves.
Talonflame received a drastic nerf in Generation VII when Gale Wings was modified so that it could only work if the user had full HP. Despite this, Talonflame remains a staple in most Kalos teams. Its Flying-type means it not only loses but becomes immune to Ground. It, however, becomes quad weak to Rock and gains a weakness to Electric.
Turtonator
With a decent Base Stat Total of 485, Turtonator is not the strongest Fire-type. However, its dual Fire/Dragon typing gets rid of its crippling weakness to Water. It only inherits a weakness to Dragon, because Fire is resistant to both Fairy and Ice, which means it takes the best of both types, creating a superior creature. It only learns one Dragon-type move via level up, though, but it has access to several more via TM and TR.
Introduced in Generation VII, Turtonator is exclusive to Pokémon Sun & Ultra Sun, where it can be found in Blush Mountain. It can also be found in the Wild Area in Pokémon Sword.
Chandelure
One of many inspired Pokémons to come out of Unova, Chandelure evolves from Lampent when exposed to a Dusk Stone. Chandelure boasts a very respectable Base Stat Total of 520. Its overall stats are average to decent, but its Special Attack is an insanely high 145.
Chandelure inherits two weaknesses from its main Ghost-typing, Ghost and Dark, while retaining all three from its Fire-typing. However, it also gains immunities to Normal and Fighting, as well as a resistance to Poison. A fair trade, at the end of the day.
Blaziken
Torchic's final evolution, Blaziken serves as the Fyre starter for Hoenn. A dual-type Fire/Fighting mon, Blaziken has the classic 530 Base Stat Total of other Starters, with extra focus on both Attack and Special Attack. Its dual-typing grants weaknesses to Flying and Psychic-types but loses it a resistance to Fairy-types, though it also wins against Dark-types.
During the Hoenn remakes, Blaziken received a Mega Evolution. Mega Blaziken's Stats shoot to the insanely high 630 and its Attack skyrockets all the way to 160, making it even more of a menace.
Centiskorch
Recently introduced in the Generation VIII games, Sword & Shield, Centiskorch is a dual-type Fire/Bug creature. It has an above-average Base Stat of 525, with HP and Attack being its superior assets. Thanks to its typing, it replaces its immunity to Ground with one for Flying. It also becomes weak to Rock, which is problematic.
Centiskorch can learn at least one Grass-Type move to deal with Water and Rock-types, though. It's also one of the few Pokémon to have a Gigantamax form, which immediately puts him in a league of its own. Overall, it's one of the most impressive Fire-types in Galar, which explains why it's Kabu's ace during his Gym Leader battle.
Incineroar
Alola's Fire-type Starter, Incineroar was immediately popular. Although its design seems to suggest it's a Fire/Fighting mon, it's actually a Fire/Dark creature, a refreshing change after three consecutive generations with Fire/Fighting starters. Incineroar has generally balanced stats, with Attack as its highest advantage.
Its typing means it retains all three Fire-type weaknesses and gains an additional one to Fighting. It also gains an immunity to Psychic, as well as resistances to Dark and Ghost. Alola's starters are the best ones of the later generations and Incineroar is a big part of that.
Infernape
And speaking of starters, Infernape has to rank as one of the absolute best of any generation. The consensus is that Infernape is the best starter to choose for any Sinnoh playthrough thanks to its advantageous Fire/Fighting type. It makes the most out of its 530 Base Stat Total by giving special care to its Attack, Special Attack, and Speed. Infernape hits very hard and very fast, making it a considerable threat.
Like Blaziken, its Fighting secondary typing grants weaknesses to Flying and Psychic, while eliminating Rock. If the Diamond and Pearl remakes indeed happen in Generation VIII, then perhaps Infernape, along with its fellow Sinnoh starters, Empoleon and Torterra, will receive a Gingantamax form, but that's still a very big "if."
Charizard
When it comes to popular starters, hardly any of them hold a candle to Charizard. Insanely beloved, Charmander is as popular today as it was back in 1998 when it was first introduced. A dual-type Fire/Flying Pokémon, it has a Base Stat Total of 534, with Speed and Special Attack as its highest stats.
For years, fans wondered why Charizard was not a Dragon. In generation VI, upon receiving its Mega Evolution, it finally became one, at least in Pokémon X. Its regular and Y forms are weak to Water, Electric, and quad weak to Rock. It becomes immune to Ground and gains resistance to Fighting. Its X form loses the weakness to Water, retains both Ground and Rock, and gains one to Dragon. Charizard also received a Gigantamax form in Gen VIII, confirming its place as one of Gamefreak's mascots.
Camerupt
One of Hoenn's hidden jewels, Camerupt was just okay during Gen III but received a considerable boost in Gen VI. Initially, it had an okay 460 Base Stat Total, with high Attack and Special Attack, but pitiful Speed and average everything else. Upon receiving its Mega Evolution in Gen VI, its stats went to the extreme. Its Attack, Defense, Special Attack, and Special Defense became quite strong, but its Speed became even worse.
Its dual Fire/Ground typing makes it quad weak to Water and it does retain its weakness to Ground. However, it loses the one to Rock and becomes immune to Electric. It also gains a resistance to Poison, although it loses the ones to Ice and Grass. Camerupt may be a complicated Pokémon to use, but if used properly it can be a real weapon.
Volcarona
A Pokémon so strong and impressive that many believe it to be a Legendary, Volcarona is indeed a wonderful creature. A dual-type Bug/Fire mon, it loses its weakness to Ground but becomes four times weak to Rock. However, with twice as many resistances as weaknesses, Volcarona is just fine in the type-matchup department.
With a very high 550 Base Stat Total, Volcarona is a very fast Special Attacker with high Special Defense. It actually learns both Bug and Fire-type moves by leveling up and can learn Psychic, Electric, Poison, Flying, and Grass moves via TM. Overall, Volcarona is a truly majestic creature that any trainer would want to have on their team.
