Collum

My biggest sculpture yet.

Collum is a massive, armored demon. Its back is covered in armor that is impossible to break, even with diamond, the hardest material known to man. It has one eye, which is in its chest. This eye is its only known weakness. Collum controls an element with each of its limbs:
Its left arm controls water. It has a large claw, similar to that of a crab, only double. It can blast water from the hole in the middle of these claws.
Its right arm controls fire. It has a huge hand with incredibly sharp claws. It can shoot fire from these nails.
Its left leg controls ice. This lets it freeze whatever surface it is standing on in an instant.
Its right leg controls earth. It can create fissures, stalactites and rockslides just by walking.
