Jack

Jack is a sphinx and is just a bit smaller than the average cougar. He manages to be a huge asshole even though he almost never says anything, acting a lot like an extremely pretentious housecat. He can become ethereal (he essentially becomes a ghost and it's impossible to touch him, although he can't touch others like this) so he tends to annoyingly walk in on emotional, tense and private meetings and there's nothing anybody can really do about it. While he can move his face to the same extent as a normal flesh-and-blood person can, the texture feels like a porcelain mask.
