Spider-Man: Carnage

Marvel unleashed a new level of mayhem in 1994 with this one-shot that gave the symbiotic serial killer Carnage his own standalone spotlight. Written by David Michelinie and drawn by Mark Bagley, the issue dives deep into the mind of Cletus Kasady, setting the stage for the character's enduring status as one of Spider-Man's most vicious foes. It's a tight, brutal introduction that cemented Carnage's place in the Marvel Universe beyond the pages of The Amazing Spider-Man.
