Monstrous hunters and bullies of the ocean depths, karkinoi are hulking crab-like humanoid brutes that live only to destroy creatures that dare cross their path and then feed on the corpses of the vanquished. While karkinoi can walk on land, they do not enjoy long periods away from the sea, as they dry out, crack, and eventually suffocate. Karkinoi stand over 9 feet tall and weigh over 800 pounds.
