Craig is a vermin/alien
i'm not sure what he is
what I do know is that he is a very vorny predator and eats a lot
his stomach is too resistant
In addition, he has a very strong regenerative capacity, you can cut off a limb and he regenerates it without problems
This Creature was taken out of a Capsule and when it came out, it took its form
He has an enormous regenerative capacity that makes him appear invincible.
