It's in command of Xeno actions and controls the Judger Citadel while the Judgers are in statis, and has at least some self-defense mechanisms. For example, it's equipped with weapons which can fire three powerful yellow energy beams, and a large blue beam that fires from its central crystal. It can be defeated by destroying the crystals powering it.
It is a spider/crab like mechanical being. Its underside consists of metal and weapons, and its top is soft skin and wires. Beige and gunmetal in colour, with a number of spider-like red eyes. It is kept afloat by some unknown power source, likely power crystals.
