Omega White was built from the remains of the original Omega Red by an organization called the White Sky. He, along with his "siblings", was implanted with false memories that result in a strong grudge against X-Force who, as they believe, was hired by some pharmaceutical company to kill their father who discovered a cure for autoimmune diseases.
Omega White was created by writer Rick Remender for the current Uncanny X-Force story arc, Final Execution. He made his first appearance in Uncanny X-Force #25.
Major Story Arcs
Upon receiving a distress call from Deadpool, Wolverine and Earth-295 Nightcrawler embark on a rescue mission. They track him down to a cloud floating above the Pacific Ocean. Seeing no better solution, they decide to teleport inside of it, only to find themselves ambushed by the assassins of the White Sky and the Omegas. The latter easily overpower X-Force's depleted ranks, claiming they will suffer for their parents' death.
Powers and Abilities
Omega White has the power to create energy constructs similar to Omega Red's coils which he uses to drain life force from his enemies. He's also able to render himself intangible, thus becoming immune to physical attacks.
