This is The Beast's current incarnation... or at least my best approximation.
Beast's outward appearance started out as just a regular dude with big hands and feet. Later, his entire body was covered in a grey fur (soon to be replaced by blue). One of his more recent changes was becoming even more cat-like... with big ol' kitty paws and a face that just makes you want to take him home and spoil him with cat-nip toys.
His mutation is currently in flux. You can read more about the Beast, whether you prefer hairless or fuzzy, HERE.
