Spider-Man has a long and convoluted history with clones. Dating back to 1975, Spidey dealt with Professor Miles Warren, aka the Jackal, and his crazy obsession over Peter Parker and Gwen Stacy. Despite the Spider-Man clone apparently dying, he returned 20 years later in the Clone Saga story arc which resulted in the character taking on the mantle of the Scarlet Spider.
The Jackal has returned, yet again, and is causing more havoc in Spider-Man’s life with the current Clone Conspiracy storyline. Several deceased characters have returned, but that isn’t much of a surprise in a Spider-Man story. The big shock came when the wall crawler came face to face with the well-dressed Jackal.
