Magnos

Magnos the Binary Star Sentinel is a Quantum Sentinel from Zelem's Nexus who is able to manipulate gravity and mass. His abilities, although shared by most members of his species, are unique because of a natural mutation he possesses that makes him more powerful than any other fighter in his clan. Originally a gladiator who fought for sport in the ring, the Darkspore invasion forced him to join The Crogenitor Insurgency and use his abilities to repel the monstrous invaders.

History
Why would any opponent fight Magnos, the champion who crushed or shattered every being who ever faced him? How could anyone hope to stop a monster who could wield the power of gravity itself? For decades, Magnos lived for nothing more than the applause of spectators who watched him eviscerate his opponents inside the Pristine Triangle blood sport that was the center of his civilization. Like all members of his clan, Magnos possessed a superior ability to manipulate mass. But Magnos' power came not simply by genetic lineage... but the genetic mutation of Crogenitor Zelem. Zelem magnified Magnos's quantum abilities so Magnos could feed directly from any source of radiation: cosmic rays, plutonium ions, or lasers. And in the ring, Magnos was invincible

&nbsp When the Darkspore conquered the Nexus, Magnos and his mightiest opponents--the few he'd left alive--formed a devastating wrecking crew. Combining their hatred of the Darkspore, their limitless endurance and their unmatched quantum attacks, they ripped apart a dreadnought with nothing but their armored hands, and ripped a hole in the myth of Darkspore invincibility forever.
