Zoroark is mine.
It use to be chimecho and then musharna, but once I saw the film with zoroark in it I fell in love with the fox and now it's my favourite.
I also like:
Luxray, lucario, infernape, staraptor, palkia, emoga, Delcatty, Togekiss, Lopunny, Espeon, umbreon, and all the other eevee evolutions. I also seem to have a small liking of fennekin and litleo. Also pyroar. And growlithe/arcanine. And many more.
