Kaine

Kaine is a genetically unstable clone of Peter Parker, created by the Jackal during the infamous Clone Saga. Bearing Spider-Man's powers alongside a degenerative cellular condition, he emerged as a scarred, morally ambiguous figure operating in the shadows outside traditional heroism.

Few characters to crawl out of the tangled web of 1990s Marvel have proven as durable as Kaine, who made his mark in Web of Spider-Man #119 in 1994 — right in the thick of the era's most ambitious and labyrinthine Spider-Man storytelling. Created by Terry Kavanagh, Steven Butler, and Randy Emberlin, Kaine has spent over three decades haunting the edges of the Spider-Man corner of Marvel, racking up 116 catalog appearances and five collector-recognized key issues that speak to just how significant his presence has become. His deepest roots run through Spider-Girl, Amazing Spider-Girl, and Scarlet Spider, where he keeps company with the likes of Peter Parker, May Parker, and the Scarlet Spider himself — a rogues' gallery of legacy heroes that underscores how thoroughly Kaine is woven into the fabric of Spider-Man's extended mythology. If you're a fan who loves characters with genuine longevity, moral complexity baked in from the start, and a publishing history that stretches well into the 2020s, Kaine is absolutely worth your time.
