A sea slug-like aquatic creature that has grown to enormous size due to exposure to some agent or another. It digs its tentacle-like front feet into the earth, using them to attack faraway enemies. The right side of its body is covered by a shell made from pieces of spaceship; it can remove this shell and use it as an arm of sorts. An organ known as the "core" lies under the shell; whatever it is, it apparently plays a vital role in its life function. __NOEDITSECTION__
