Spider-Man Unlimited #1, May 1993
Carnage organizes a group of like-minded maniacs (Shriek, Carrion, etc.) on a murderous spree in the infamous 1993 crossover event from Marvel. In the intro issue, Ron Lim delivers this terrific splash as Spider-Man tackles Doppelganger, an evil near-mindless version of Webhead created during The Infinity War saga.
The “Comics Code” was completely superfluous by now, if not an outright joke. This storyline, which is the basis for a video game, and influenced the second Venom film, features so much bloodshed and violence its pretty much impossible to keep a bodycount.
The Green Goblin is a pussycat compared to these guys.
