John Diggle is an A.R.G.U.S. agent in a reality where Superman is Earth's only superhero.

John has worked with Superman multiple times in the past. He knows that Superman's secret identity is Clark Kent and is friendly with his wife Lois Lane.

General Sam Lane contacted John and asked him to deliver an A.R.G.U.S. red solar flare to Smallville, Kansas when Superman was kidnapped and brainwashed by Tal-Rho. John assumed the flare would be used to merely restrain Superman and was outraged when he learned Sam and John Henry Irons planned to use it to kill him. He argued that they owed Superman to explore every possibility to save him, and told John Henry that he hoped he would make the right decision. Ultimately John Henry was able to help Superman break his brainwashing without killing him.[1]

A year later, Diggle returned to Smallville and told John Henry that A.R.G.U.S. was investigating the murder of his counterpart on their Earth; and believed that Bruno Mannheim, the head of Intergang, was responsible.[2]


  • John mentions Oliver Queen in his first appearance. Following the revelation that Superman & Lois does not take place on Earth-Prime it is unclear if he was referring to the Oliver Queen of Earth-1, which would suggest that this version of Diggle was involved in the Crisis on Infinite Earths; or the Oliver Queen of his own world, who may have also operated as the Arrow for a time in the past.
