I'll have to go with Vulpix for this one. First of all, for some reason Zorua never truly grew on me, though I suppose I'm fine with it... but Fennekin? Based on appearance, that would be a no. I just can't stand that conceited little smile, I'm sorry. ^^ However, I once used a Vulpix/Ninetales as a starter replacement in BW2, so you could say that I'm a bit biased.
