One of the 90 children kidnapped and inducted into the Spartan program, Ajax-013, as he became known, was a notorious Spartan, serving amongst his brothers and sisters-in-arms during both the Insurrection and the Great War, and beyond. A specialist in close quarters operations, and electronic warfare, his keen intellect and sharp wits are tempered by an uncanny brutality in combat. Difficult to control and predict, he's forged a legacy of bloodshed and violence across dozens of worlds.
