John Diggle and J.G. Walker[src]

General J.G. Walker[1] is a corrupt former military general of the United States Army.

Walker tried to frame Master Sergeant John Diggle for the theft of a weapon of mass destruction and the murder of an enlisted soldier after MSG John's team took it from a terrorist group.

Walker's crimes were ultimately exposed, leading to him and his accomplices being incarcerated in a military prison.


At some point after the revelation of the existence of meta-humans and Damien Darhk's dark magic, Walker went rogue.

Sometime after Genesis Day, Walker became the leader of John Diggle's unit while John himself was stationed in Eastern Europe. The unit mission was to recover a nuclear weapon which was stolen by terrorists, but after recovering it, Walker and other rogue soldiers betrayed John, framing him for the murder of a fellow soldier. He then fled the scene, with the nuke.[2]

When John was arrested once again, after Prometheus tipped the feds, Walker wanted John to be transferred, so that he could be killed during the transfer, but Adrian Chase, who was serving as John's lawyer, managed to delay John's transfer by making John punch him.[1]

After Walker crimes were exposed by Felicity Smoak with the help of Helix, Walker and his loyal men fled to Russia to sell the nuke to the Markovian terrorists, but they were ultimately stopped with the intervention of Team Arrow and the Bratva. He was then arrested by A.R.G.U.S., which placed him under custody so that he could be judged for his crimes.[3]


Walker displayed a great lack of empathy, being capable of killing fellow soldiers just to frame John Diggle or selling nukes to terrorists for his own sake.

He also saw meta-humans and Genesis as the world's biggest threats, while simultaneously backing terrorists who had the same intentions.
