This is such an interesting character (and not just from a story perspective). He's gone through the most species changes of anyone, starting off as an antelope before transitioning through three or four others before I settled on warthog. In retrospect, this is absolutely the right fit for his personality, and I'm really pleased with the design. As I'm certain you all will be too :P
And in case anyone's concerned, he will have the more musclegut body type option. There's no question.
