I love Ben Reilly and Kaine Parker. They're respectively my favorite comic book character and my favorite recent addition to the Spider-Man mythos (with Miles Morales).
However, looking back at the clone saga, I wish it was crystal clear Ben was
not the original Peter Parker. It cheapened both Ben's newfound identity and Peter's trials and tribulations since the 70s (Jean DeWolfe's death, the mariage with MJ, KLH, Venom, Maximum Carnage should be Peter's adventures, not Peter's clone adventures).
If I had to sum up what I feel about this, it's that it feels less personal when Peter's dead parents come back to life (as androids but still) to torment Peter only to learn a few years later that it wasn't the
real Peter. Just his
clone.
Ben was fine being Peter Parker's clone. He made his own life with his own choices and he was happy. Ben was Peter's brother and they had an incredible chemistry. He had this charming bravery as the Scarlet Spider and a happy-go-lucky attitude as Spider-Man that made him my favorite Spider-Man.
What makes Ben great is his identity dilemma: he is an alive 616 "What if..?" of Peter. I loved his adventures as the second Spider-Man in the 90s. He felt to me as a mix of Wally West as the Flash and Dick Grayson as Batman.
What I wish happened throughout the 90s Clone Saga would be that Ben knew he was Peter's clone and that Peter and MJ stuck around NYC while Ben was Spider-Man. My favorite issues were the ones where the Powerless Peter was Ben's "guy in the chair", guiding him, advising him and checking up on him (for e.g during the Skeleton arc or the Spider-Carnage arc).
This was the way fans and Marvel could have their cake and eat it too! Think about Ben Reilly as the relatable, down on his luck, happy-go-lucky Spider-Man whereas Peter was the down-to-earth, grown-up married man with a baby on his way. Peter and MJ would be a central part of Ben's support cast, like they were in the end of the 90s Clone Saga. And eventually, little Mayday would be his niece.
This is why this panel is my favorite panel on any Spider-Man comic book.
