Biography[]
Early life[]
- "Come on, he's Superman. I've fought beside him. He's the best we have. Oliver would've said that. Hell, they all would have."
- —John Diggle[src]
At some point, John Diggle joined A.R.G.U.S. and worked with Lyla. Diggle befriended Oliver and fought alongside Superman. Through his history with Superman, Diggle became aware of the multiverse. He also became close friends with the Kent family.
Through Diggle's time as a vigilante, he had seen many things: doppelgängers, parallel worlds, and a "glowing box". However, after Oliver died by unknown causes, he put being a vigilante to rest, tired of losing the people he cared about.[1]
A.R.G.U.S. agent[]
Helping the Kent family[]

Lois and Diggle confront Sam Lane.
Doing a delivery job for A.R.G.U.S., Diggle dropped an A.R.G.U.S. weapon off for Lyla in Smallville. After it was successfully sent to General Sam Lane, Diggle talked to Lois Lane and they caught each other up on the events of the last few months.
When going inside to see Sam, Diggle found out along with Lois about what the equipment he is delivering is really being used for—to disable the powers of Superman. Along with this information, Diggle was introduced to John Henry Irons, an individual from another Earth. Diggle then objected to Sam's plan. He was also angry that Sam was being assisted by somebody from another Earth without telling him. Diggle then requested that him and Sam have a talk on this situation.
Diggle argued his point to Sam, objecting to the latter's reasoning of Clark being too far gone to save, as well as using both Diggle and Lyla to achieve this goal. He then left as Irons came in to see Sam.[1]
Meeting with John Henry Irons[]

Diggle talks to John Henry about Bruno Mannheim.
In 2022, Diggle visited Smallville again to meet with John Henry Irons. Diggle told John about how Bruno Mannheim murdered his doppelgänger in 2015, a case that A.R.G.U.S. was investigating. Diggle then asked for his help in finding out why the John Henry of this Earth was murdered.[2]
