Collector of Worlds

The Collector of Worlds is an alien android with obscure purposes.

2015
The Collector of Worlds was informed by Orb-One of the First Leader's retrieval of certain assets and received the go-ahead to proceed with his plans.

The Collector moved his his ship to Metropolis, and hovered above downtown. He proceeded his plan by launching a probe at the city, which quickly tunneled deep underground. The device created a force field that cut through everything, including bridges, and cut off communication. The conservation of Metropolis in a bubble was complete in minutes.

The Collector activated an energy beam from the bottom of his ship, targeting the force field around Metropolis.

The Collector anticipated the arrival of Martian Manhunter, the Atom and the Flash aboard his vessel, and descended toward them upon a platform, informing them of their intrusion. When questioned about his presence, he listed his many names, until finally introducing himself as the Collector of Worlds. He proclaimed it was futile to prevent him from preserving Metropolis. The Collector intercepted a direct attack from the Flash, before being telekinetically levitated by Martain Manhunter, who attempted to disable his systems. However, the Collector's reinforced skeleton proved to be too powerful to dismember. The Collector stated he was aware of Manhunter's distraction, and casually dropped the Atom from his grasp. After making quick work of the three heroes, the Collector opened a hatch beneath the Leaguers, sending them plummeting from his vessel.
