All of the superweapons were thought to be the same and nearly identical. Until recently - a newly awoken Commander constructed a forward base of operation on this metal planet seeking the power of the superweapon. The Commander noted that this metal planet was smaller and had the ability to move between systems. The Commander claimed the superweapon and attempted to activate the ancient weapon from its dormant state. It was operational. By this time, the planet let out an ominous song - the metal planet was alive. And hostile. Every unit under the Commander's control had been influenced by the planets song and had turned hostile. The Commander fled the planet and warned his allies of a newly awoken Commander that was in fact, the super weapon itself.

So pretty much the superweapon is a Commander AI
