Page "Jackal (Marvel Comics)" Paragraph 8

Reilly returns years later to New York City, allied himself with Spider-Man, and became the Scarlet Spider.

The Jackal also returned to unleash his clone army and convinced both Parker and Reilly that Reilly was the real Peter Parker and that the other man was the clone, respectively.

Jackal created a number of other Peter Parker clones who came into conflict with Spider-Man, the Scarlet Spider, and Kaine.

The Jackal clone who was thought to have died at Shea Stadium was revealed to have survived and married the Gwen Stacy clone under an assumed name.

Ultimately, the Jackal, in the process of attempting to kill and replace millions of people with clones he could control, was killed falling off a tall building while trying to save the Gwen clone.
