Raiden

A creature of the early '90s Marvel universe, Raiden burst onto the scene in 1994's Venom: Nights of Vengeance #1, courtesy of Howard Mackie and Ron Lim. This brief but memorable presence shares pages with none other than Eddie Brock himself — the lethal protector Venom — alongside a cast including Kass, Trent, and Sean Knight, making for one of that era's darker, grittier corners of the Marvel universe. With only a handful of appearances to their name, Raiden is the kind of deep-cut discovery that reminds dedicated collectors just how richly populated — and wonderfully strange — the symbiote-adjacent world of '90s Marvel truly was.
