Kaine Parker, the clone of Peter Parker, has had a long history. First he was a crazed villain, then he was a murderous ally who cause Peter more trouble than he was a help, then he was killed and brought back to life and turned into a horrible spider monster. It was only once Peter concocted a cure to the spider virus that infected New York City that finally cured Kaine, not only of his beastly condition, but also of his disfiguration and insanity caused by the imperfect cloning process that created him.
Once he was of clear mind and the Spider Queen was defeated after the events of Spider-Island, Kaine left town, heading for Houston, with the Spider-Man costume Peter had given him. The only problem he had, is that Madam Web had tampered with the costume so that it could no longer turn invisible, and was stuck in a red and black pattern in an attempt to force him into becoming a hero. Even though Kaine believed he didn’t deserve being a hero because of his past actions, he could stop himself from trying to save people when he saw that he could do something. People in the city started calling him the Scarlet Spider due to his red outfit, which Kaine didn’t like at first because he believed he would tarnish the name once held by his clone “brother” Ben Reilly. Eventually Kaine accepted the title and role as a hero, and tried to do his best to be the new Scarlet Spider while in Houston.
