Well, If we go through the assumption that all Fanus are supposed to have animal ears and a tail, that would mean the only other two Fanus characters (Sun and Velvet, because even though we can assume Adam is one, we don't know for sure; Plus, his "Horns" just look like hair to me) must have Monkey ears and a Rabbit tail, respectively. It doesn't look like either one of them has those parts (Monty recently released the character model of Velvet for the Battle Armor contest, and it doesn't look like there's a tail there). So, unless every Fanus we've seen so far is actually a half-Fanus, it's safe to assume that Fanus only posses one animal body part.

The only thing that makes me doubt ^ is that all the characters mention a "Fanus Heritage". Maybe the very first Fanus had two or more parts, but have been eradicated by, or simply inter-bred with, Humans. Just a thought.
