Green Goblin II

Origin - Amazing Spider-Man #121-#135

by Ross Andru, 1974

Suffering clinical psychosis from a bad batch of LSD, Harry Osborn witnessed the death of his father battling Spider-Man. Stripping the Green Goblin off his father, he took on the identity of the Green Goblin in order to avenge his father.

Devoting all his time to practicing with the Green Goblin equipment and exploring his father's secrets, Harry becomes more and more withdrawn from his friends and sullen towards Peter in particular. Suspecting the truth, Harry begins spying on Peter and going through his personal belongings. It isn't long before Harry witnesses what he's always suspected: Peter Parker is Spider-Man, and Spider-Man killed his father.

From Amazing Spider-Man #135: Epilogue: it takes place here, in a warehouse we've seen before, and it features this youth whose face is definitely familiar. Yes, it's the warehouse where Norman Osborn died. Yes, the youth is Harry Osborn. And yes, this is the former secret headquarters of the man who killed Gwen Stacy. As for the rest, we must wait for tomorrow.
