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.

The 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, Diggle met Luke Fox and played poker with him along the latter's attempted murderer, Russell Tavaroff. Diggle later witnessed Tavaroff fighting Fox in an alley and stopped him. As Tavaroff told him it was not his fight and justified his own crimes, Diggle punched him in the stomach once more and scared him away.

Diggle then bought painkillers for his headaches and for Fox, who refused the offer. Diggle sat down next to Fox 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". Fox left Diggle, and they bid goodbyes to each other.

The Godspeed Imperative
Weeks later, Diggle 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, Diggle witnessed Allen interrogating the Godspeed and went to clean up the mess when the Godspeed escaped the Pipeline. However, Diggle was surprised by Allen's sudden burst of anger towards Chester P. Runk with the damaged device.

Diggle talked to Allen afterwards and asked him about his aggressive attitude towards his team. Allen told Diggle that he was worried about his future and his doubts on going to 2049 to check out his daughter. Diggle convinced Allen 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 Diggle to investigate August Heart's whereabouts in 2021. On the way out, Diggle experienced a headache and Horton was able to sense infinite voices in Diggle's head. Diggle assured Horton that he is capable of fighting and encountered a Godspeed. Diggle 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. Horton and Frost brought him to S.T.A.R. Labs and restored his memory. Diggle, on the other hand, brought the damaged Entropy Trap with him and bid goodbye to Runk.
