Vulpix is a small, quadrupedal, canine Pokémon. It has a red-brown pelt with a cream-colored underbelly. It has brown eyes, large, pointed ears with dark brown insides, and a triangular dark brown nose. Its paws are slightly darker than the rest of its pelt and have light brown paw pads. On top of its head are three curled locks of orange fur with bangs, and it has orange tails with curled tips. It is most commonly seen with six tails. However, Vulpix is born with only a white tail that splits as Vulpix grows. The tails grow hot as Vulpix approaches Evolution.

Vulpix can manipulate fire to such precision as to create floating wisps of flame. These wisps are sometimes mistaken for ghosts by humans, but Vulpix uses them to assist in catching prey. Inside its body is a flame that never goes out. When the temperature outside increases, it will expel flames from its mouth to prevent its body from overheating. Vulpix performs this even when sleeping, as mentioned in the Sleep Style Dex. Vulpix is known to feign injury to escape from opponents too powerful for it to defeat. Vulpix is most commonly found in grassy plains.

Forms
Vulpix has a regional form: Alolan Vulpix.

In the Alola region, Vulpix has adapted to snowy mountain peaks and developed a snowy white pelt. It has pale blue paws, blue eyes, and dark blue inside its ears. Its snout is more pronounced and pointed than that of non-Alolan Vulpix. The locks of hair on its head and its six tails are curlier and have a wispy appearance.

Alolan Vulpix is believed to have arrived in the region at the same time as humans but moved to the snow-capped mountain to avoid other Pokémon. It can be found in small packs, called skulks, that are led and protected by Ninetales. Alolan Vulpix can expel breath as cold as −58 °F (−50 °C), which is capable of freezing anything. While it is not suited to warmer environments, its tail can produce ice to lower the surrounding temperature if needed. An old, local name for this Pokémon is "Keokeo", referring to its white pelt. Weavile is a natural predator of Alolan Vulpix. They can also be found in the Polar Biome of Blueberry Academy's Terarium, where Alola's island life is simulated. As mentioned in Pokémon Sleep, Alolan Vulpix prefers to sleep in freezing cold places. Whenever its resting spot starts to warm up, Alolan Vulpix will use its cold breath to change the surrounding area into a more comfortable temperature.
