HE HAS COLORS :D
I'm not too too happy with them, but it's close to what I wanted. Plus he can change colors from his diet, mood & lighting, so I weaseled this palette in xD

Ulysses can create crystals out anywhere on his body at will. He can also summon or draw them out from the earth can use them as he pleases (ex: make a staircase of them to walk on, like a boss).

Ulysses belongs to me :D
