>>22947482>Gen 6 VulpixYou mean Gen 6 Zorua. Both Fennekin and Zorua have only one tail while Vulpix has six.
Also should point out that all three are very different even though they're all just a bunch of foxes.
Vulpix and Ninetales have the multi tail characteristic from the Kitsune legend
Zorua and Zoroark have the mischevious trickster aspect of the same legend
The Fennekin line is based off Fennec foxes, found in North Africa. They're practically made for the desert climate unlike the other two.
So even if they are all just a bunch of foxes, they're certainly very different in their own right.
