It has vivid flame-orange fur with a bushy yellow mane, a wide, fluffy flame-shaped tail, and a tuft of yellow fur atop its head. It has a short catlike muzzle, wide black almond-shaped eyes, and a small black triangular nose. Its ears are long and rabbit-like, with flare-like tips. It has large, bulky paws with no visible claws. Its body is generally bulkier than most of the Eeveelutions.
Flareon have the ability Flash Fire. Flash Fire allows Flareon's Attack to increase when it is hit by a Fire-type move. It has a flame sack in its body. Its body temperature can reach up to 1,650 degrees Fahrenheit before battle.
Flareon is one of the evolutions of Eevee that is caused by exposure to a Fire Stone.
Shiny Flareon has a similar coloration as its pre-evolution, Eevee.
Like all Eeveelutions, Flaron's appearance is feline, mainly resembling lions and large long-haired domestic cats, such as the Norwegian Forest Cat. Flareon's tail is flame-shaped to signify its association with fire. It also possesses a thick mane, and a generally bulky body shape, resembling both a Norwegian Forest Cat (like its pre-evolution Eevee), and a lion. Lions are known to be associated with heat and fire, due to their environment in the sweltering savannas of Africa. The Norwegian Forest Cat, a large long-haired breed of cat, has a bushy tail and a thick mane of fur around its neck, highly resembling Flareon.
Flareon's name originates from the words flare and eon. Flare means to blaze with a sudden burst of flame. Eon means an indefinitely long period of time, relating to the long string of eight eeveelutions.
