Grecin

A genetically-engineered assassin used by the inhabitants of Poydras. The Grecin is almost unstoppable once it is programmed with a target and implodes upon destroying that target. Karyna put one on board the Titanic to make sure Leximas was killed. After it decapitated John Jacob Astor, Bradley Dillon managed to drop a smokestack on it. That only made it mad. Leximas rescued Bradley from the monster, which then went down with the ship. The Grecin itself was an orange-skinned, vaguely ape-like creature standing six-feet in height. It had green eyes, large fangs and a rudimentary intelligence. ("That Sinking Feeling" [WAY])
