Along with Alolan Sandshrew, Vulpix gained an Alolan variant in Pokemon Sun/Moon. Clearly based on an arctic fox, Alolan Vulpix is an Ice-type Pokemon, which contrasts with the Kanto/regular Vulpix's Fire-typing. With the release of part 1 of The Hidden Treasure of Area Zero, Pokemon Scarlet & Violet players can get their own Vulpix in The Teal Mask.
Pokemon Scarlet & Violet: How to Get Alolan Vulpix
If you have the Indigo Disk DLC, then you might find an Alolan Vulpix in the Polar Biome of Terarium, but only in Pokemon Scarlet.
