- — Diggle to Oliver Queen[src]
John Diggle (born 1977), known mononymously to Oliver Queen as Diggle, is Oliver's bodyguard and chauffeur and an ex-soldier. Oliver, though, tries to avoid him as much as he can. In "Lone Gunman", it is revealed that he had a brother who died working as a bodyguard and thus left behind a wife. He discovers Oliver is Arrow after he is taken to Oliver's lair to recuperate after being shot by Deadshot.
Trivia
- The character's name is likely a reference to Andy Diggle, the author of Green Arrow: Year One, upon which Arrow is largely based.
- Despite his appearance, Diggle is very proficient in hand-to-hand combat.
- Because of the high level of his hand-to-hand combat skills it can be assumed he received this level of training as a young child or during his time in the military. If the latter then Diggle was most likely a member of an elite unit such as Delta Force or SEAL Team 6.
- John Diggle is currently the only character to know Oliver Queen's secret identity, Arrow. He discovered this in "Lone Gunman".
