Kaine is the Jackal's first temporary success to clone Peter Parker but the flawed cloning process is left deformed and mentally unstable. Kaine is later identified by the Jackal as "Parker 3.0"the implications of this are unknown. The Jackal discards Kaine because the clone starts showing early signs of the degeneration process, and Kaine experiences a strong feeling of rejection similar to that between a father and son. Kaine realizes the partial degeneration also caused a slight amplification of the powers he "inherited" from Peter. Not only has his strength, speed, and agility been copied from the original Peter's, but he gains a "precognitive sense" that shows him flashes of the future (an amplified version of Peter's spider-sense). He also possesses a "Mark of Kaine", a burning touch that he uses to leave eaten away handprints on his victims' faces. Though never explicitly stated within the story, in a later interview former Spider-Man editor/writer Glenn Greenberg revealed that the Mark of Kaine was meant to be another analog of one of Spider-Man's powers, namely the ability to cling to walls.
