Ender

Ender is one of the S-Force's greatest enemies. He "ends things. People, planets, galaxies".

Biography
Ender appeared on Earth while Coop was fighting the S-Force and wanted to partner with Coop to rule the universe together. But, when Coop insisted he was good and refused Ender's offer, he instead fought with Coop. Ender lost when Coop integrated the Zorps into Megas and used their power, much to the dismay of the S-Force. When Coop activated the S-Force's greatest weapon, and fired it at Ender, he accidentally opened a matter-antimatter rift, a vortex that sucks anything into it. It claims Ender, pulling him in.
