The Jackal's laboratory, New York City
Web of Spider-Man #119 (1994)
Unable to live a normal life because of his disfigured features, Kaine's anger grew with his strength. Most of all he hated Scarlet Spider whom he, like the Jackal, believed to be the original Spider-Man, and thus the reason for his tormented existence. Believing Peter to be a successful clone, Kaine took it upon himself to ensure that Peter led the charmed life denied the Jackal's other experiments. This ambition eventually led Kaine to murder the Grim Hunter and Dr. Octopus (Otto Octavius).
Kaine followed Ben around the world, working occasionally as a high-priced assassin. In Salt Lake City, three years after leaving New York, Kaine killed Detective Louise Kennedy, the only person who ever made Kaine feel loved, after learning that she was in league with the local mob. Ben was spotted at the scene shortly after, and Kennedy's partner, Detective Jacob Raven, eventually tracked Reilly's fingerprints back to the original Peter Parker in New York City and arrested Peter. Peter was exonerated only after he threatened to make his secret identity known and Kaine confessed to the crime in another effort to preserve Peter's happiness. After Ben was "revealed" to be the original Spider-Man, Kaine escaped from police custody but was killed by Spidercide, a shape-shifting clone of Spider-Man. The Jackal put Kaine's body in a clone regeneration pod, where it was revived some time later.
Still attempting to crush Reilly's spirit, Kaine used Elizabeth Tyne (who was living under the assumed name of Janine Godbe after shooting her abusive father), the love of Ben's life since they had met in Salt Lake City. Threatening to expose her to the police, Kaine ordered Janine to fake her own suicide and leave Ben as he wandered America. After Ben took the role of Spider-Man, Kaine lured Janine back to New York and attempted to kill himself and them. Their love inspired him to relent, and both Kaine and Janine surrendered to the police.Kaine later escaped from prison and was last seen in Greece. His current whereabouts are unknown.
