Due to the Punisher's homicidal nature, few of his foes became recurring antagonists, the most notable of these being the severely-scarred enforcer Jigsaw. The Punisher also acquired a nemesis in the form of the Kingpin, a longtime Spider-Man and Daredevil foe, and developed enmity with Daredevil himself, who likewise abhorred and fought against the Punisher's brutal methods. Villains such as the Jackal, Bushwacker, Doctor Doom, The Reavers and Bullseye would be used to provide more of a challenge for the character. In addition, heroes such as Spider-Man, Captain America, Daredevil, Ghost Rider, the Hulk, Wolverine, Nick Fury, and Moon Knight – and, on at least two occasions, the preadolescent team Power Pack – would appear. Often the stories would use the appearance of those heroes to provide commentary on the difference between the Punisher and those more colourful characters. During Don Daley's run on "The Punisher" title, his version of justice was described by the editor as "an eye for an eye".
