John Diggle (UE-43)

John "Dig" Diggle is the head of ARGUS.

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 ARGUS 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 save the world. Before John left, he told Irons that he should make the right choice.
