Probably because it was the first Gen V pokemon introducted and was showcased in its own movie along with Zorua. Zoroark always struck me as a poor mans Lucario. He may even get a bigger fanbase if Pokemon Co. decide to have him as their new rep for Super Smash Brothers IV.Scrafty. Zoroark sucks. Idk why it has such a huge fan base. It's terrible. Scrafty is just awesome. Hi Jump Kick, Ice Punch and such, it's just awesome.
And it's adorable. <3
