Skullhuggers: Xlyym uses Skullhuggers, these devices attach to a skull and allow Xlyym to control his victims.
Xlyym is a member of the Fomalhauti race, and profited from his race's conquest of the Banari, a race whose entire male population had been wiped out. He made one of the Banari, Trieste, his consort, and placed them under his control using Skullhuggers. He also benefited from the Haab, the Banari's servant race. At some point, he joined Skeletron's Starblasters in their quest for the Starbrand, although he was frequently annoyed at having to take orders from Skeletron.
Xlyym was present aboard the Dark Seed as Nygorn presented Skeletron with the captured Uatu the Watcher. After learning the history of the Starbrand from the Watcher, Skeletron dispatched Xlyym in a cargo vessel to earth's Atlantic Ocean to create a diversion while the others attempted to capture Kayla Ballantine, current wielder of the Starbrand.
Xlyym chaffed at taking Skeletron's orders, but agreed to install two Planetary Thrusters on the ocean floor to tear the earth apart.
