OKAY I think this is all I'm gunna do with this for right now, I have other more pressing projects to attend to, but Willow would not leave me alone about finally designing her pokesona all day Friday, so I had to get SOMETHING onto a page.
With that said, here's the form Willow chose: braixen with some ninetales traits. I haven't depicted any tailes here, but I'm thinking they usually curl together as one and fan out when she pulls out her wand to cast magic.
