Ultimate Spider-Man, Vol. 1 #7 (2001)

Secret Identity
Spider-Man's first outing against a super villain could have gone better, but could also have gone much, much worse. Peter managed to get the Green Goblin over to a much more secluded region, where police helicopters unfamiliar with the situation try to arrest both. The Green Goblin takes several bullets in the chest and ends up in the river, but Spider-Man avoids serious injury. In the aftermath, Harry Osborn reveals the Green Goblin's identity.
