Vulpix is a small, quadruped, fox-like Pokémon. It has red-brown pelt, brown, pupil-less eyes, large, pointed ears with dark brown insides, and six orange tails with curled tips. The tails grow hot as evolution approaches for this Pokémon. Vulpix also has curled locks of orange fur with bangs on top of its head. At birth, Vulpix has only one white tail, which apparently splits and grows more beautiful and warmer as it grows older. Vulpix has a cream underbelly, and brown feet with lighter brown paw pads.
Vulpix has a flame inside its body that never goes out, and is capable of manipulating fire to such precision as to create floating wisps of flame. When the temperature outside increases, it will expel flames from its mouths to prevent its body from overheating. Vulpix is known to feign injury to escape from opponents too powerful for it to defeat. Vulpix can be found most commonly in grassy plains.
