fire type pokemon

Defense
The Fire type has its pros and cons defensively. Ground, Rock, and Water moves are all very common, while most of the Fire type's resistances are of little use. Most Fire-type Pokémon will not survive too long in battle; they must deal damage quickly in order to earn their slot on a team. This reflects the nature of fire being a glass cannon; a very destructive force yet at the same time being very fragile. The biggest flaw Fire types have is that all Fire-type Pokémon are weak to Water, with the exception of the legendary Pokémon Reshiram, which is a dual Dragon/Fire type.
However, not only does the Fire type have five resistances, among them being a key resistance to the powerful Ice, but it is also immune to burns, making Pokémon of this type key physical sweepers. Also, most Fire types can at least learn SolarBeam to counter all three of the type's weaknesses.
Offense
Offensively, Fire is very powerful. The ability to deal super-effective damage to Steel-type Pokémon is very useful for Pokémon that specialize in special moves, as many Steel-type Pokémon typically have high Defense but a low Special Defense and would suffer with any special moves thrown at them. Also, Fire-type moves are generally powerful, with around half of its damaging moves having 100 or more for power and 17 out of 27 having 80 or more. While Fire is resisted by four types, two types are hindered by their own bad Special Defenses and relative scarcity therefore keeping their moves rather valuable. Although Fire types often have below average defensive stats, they often have high Speed and Attack stats, making them great offensive Pokémon.
Fire is super effective against four types, tying it in amount with Ice and Rock. However, double weaknesses to Ice and Rock are slightly more common, and Ground and Fighting hit even more types super-effectively. Despite this, Fire is unique in that it is the only type that can cause 5× times damage, due to the combination of Paras's evolutionary family's double weakness and the Ability Dry Skin. Fire types also possess higher offensive stats compared to Ice and Rock types. Many Fire types can now learn Grass moves, which can make double resistances to Fire useless (in this case, Water/Rock types, who are doubly weak to Grass).
