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. It fluffs out its fur collar to cool down its body temperature. It stores some of the air it inhales in its internal flame pouch, which heats it to over 3,000 degrees Fahrenheit.
