What Happened To Every Spider-Man Clone?
1. Ben Reilly
The one that started it all, ol' Benny boy has had quite the journey in the decades he's been around.
In the beginning he was, well, he was just a clone, introduced as that and only that by Gerry Conway when he first introduced The Jackal. But then Ben came back in the 90s as The Scarlet Spider, and soon afterward, the Clone Saga began in earnest.
During this time, Ben Reilly was at his most hated as a character, mostly due to it being transparently obvious that this whole thing was just Marvel trying to replace Peter as Spider-Man so they didn't have to have a married Spider-Man. That didn't take, of course, but Ben was still kicking around, so for a while they just killed him off and called it good.
After several instances of him coming back, and then dying, and then coming back again, and then him being The Jackal (but we don't talk about that), we finally come to the present day, where he and Peter basically co-exist as equals. To the point where Ben is an active player in the current Devil's Reign storyline.
