"Flareon's fluffy fur has a functional purpose-it releases heat into the air so that its body does not get excessively hot. This Pokémon's body temperature can rise to a maximum of 1,650 degrees Fahrenheit."
Flareon always seems to pop up in player teams, especially when the Special Attack stat is boosted via training, because it makes Flareon a very deadly opponent. And why not? Fire-Types are very cool, and very powerful, and it's worth it to have a powerhouse on your team when in a pinch.
Flareon's Basic Attack is Ember, while its Special Attacks are Heat Wave, Fire Blast and Flamethrower.
