Deathstroke

Background
U.S. Army officer Slade Wilson volunteered for dangerous hormone experiments designed to create super soldiers. His strength, agility, stamina, and brain capacity were increased. Slade became a mercenary following the end of his army career and sold his services to the highest bidder as one of, if not the best, mercenaries in the world.

Alternate Future
In the alternate timeline where the conflict between heroes and villains has escalated to war, Deathstroke has joined forces alongside Lex Luthor in fighting the remnants of the Justice League.

While initially confronting and attacking Wonder Woman during the final battle, he steals her lasso and uses it on Batman, trapping him and attempting to beat him to death save for the intervention of the Joker, who, in a fit over who should kill Batman, fired a bazooka at them both.

While surviving the blast relatively unscathed, Deathstroke defended himself against Brainiac's invading armies before being digitized alongside Cyborg, Wildcat, Killer Croc, and Circe.
