John Diggle (Earth-1: Pre-Crisis)

"I've been a spy, a vigilante, a soldier...hell, I've even been the Green Arrow. The most important job I've ever had is as a dad."

- John Diggle

John "Dig" Diggle is the head of A.R.G.U.S., the former leader and member of Team Arrow, the best friend of the late Oliver Queen and the vigilante known as Spartan.

Early Life
At some point, John Diggle dropped out of college and joined the United States Army.

He later married Lyla Michaels and they had two children, Sara Diggle and John Diggle, Jr..

Oliver Queen's Funeral
"Oliver may be gone, but his mission endures. That mission lives on, Oliver lives on in the people he inspired. Some will take that mission to the rest of the world. Maybe even beyond that. Because if the past eight years has shown us anything It's that this universe is far bigger than any of us could have dared imagine. Even if it is a little less bright without him in it."

Trip to Gotham
In 2021, John Diggle went to Gotham City for an appointment at Gotham General due to his fogginess in his mind. During the trip, John Diggle met Luke Fox and played poker with him along the latter's attempted murderer, Russell Tavaroff. John later witnessed Tavaroff fighting Luke in an alley and stopped him. As Tavaroff told him it was not his fight and justified his own crimes, John punched him in the stomach once more and scared him away.

John then bought painkillers for his headaches and for Luke, who refused the offer. John sat down next to Luke and told him about anger, and how it could win a fight. He also told him that he would make his family proud and was interrupted by the flickering Batsignal, which sends a Morse code message that says "Need Fox Help". Luke left John and they bid goodbyes to each other.

The Godspeed Imperative
Weeks later, John went to Central City with the Entropy Trap in order to stop the Godspeeds from wreaking havoc in the city. He approached Team Flash and successfully captured a Godspeed with Barry. Soon, John witnessed Barry interrogating the Godspeed and went to clean up the mess when the Godspeed escaped the Pipeline. However, John was surprised by Barry's sudden burst of anger towards Chester P. Runk with the damaged device.

John talked to Barry afterwards and asked him about his aggressive attitude towards his team. Barry told John that he was worried about his future and his doubts on going to 2049 to check out his daughter. John convinced Barry to do so, using their common role as a father to remind him that being a father is the most important role he has ever had.

Cecile Horton later brought John to investigate August Heart's whereabouts in 2021. On the way out, John experienced a headache and Cecile was able to sense infinite voices in John's head. John assured Cecile that he is capable of fighting and encountered a Godspeed. John shot him with nanites, courtesy of Ray Palmer, and temporarily defeated him. However, the headaches resurfaced and brought him on the ground until Frost arrived, protecting him from the Godspeed. The trio then went to the site of the future Dayton Labs, seeing a scared man hiding from them. Cecile and Frost brought him to S.T.A.R. Labs and restored his memory. John, on the other hand, brought the damaged Entropy Trap with him and bid goodbye to Chester.

Called to Smallville
"I can't imagine the courage it took for you to survive whatever the hell it was that got you here, but you're gonna need that courage today. The world will be praying you made the right call."

- Diggle to John Henry Irons

After receiving a call from Sam Lane, Lyla sent John to Smallville in order to deliver the ammunition for the Red Solar Rocket. However, Sam did not inform him about his plan to kill Superman as a contingency plan. John and Lois confronted him and questioned his choice. Sam defended himself and claimed that A.R.G.U.S. would not have given him the ammunition if they knew about his plan. John then brought Sam to a strong conversation, telling him that killing Superman is not the way to safe the world. He later reminded Sam that as Spartan, he fought alongside Superman and that he was the best of they have. John told Sam that Oliver, along other heroes, would say the same. Before John left, he told Irons that he should make the right choice.
