During the events of Halloween Horror Nights: Islands of Fear back in 2002, Carnage, also known as the ruthless, murderous, and pure evil serial killer Cletus Kasady, was the head of the island-turned-scare zone called Island Under Siege. He appeared specifically in the haunted house called Maximum Carnage, based off the Marvel storyline of the same name. However, the maze alters the storyline into Carnage slaying all of the superheroes that have came after him before he took over the world. The Island Under Siege scare zone was also themed exactly like the maze. It is known that in the maze, people found bodies of defeated superheroes hung up as trophies in Carnage's evil hideout, such as Spider-Man decapitated, Wolverine's arms ripped apart, and Captain America covered in blood along with his shield. Carnage summoned other villains such as Crossbones, Sabretooth, the Silver Samurai, and Kraven the Hunter to chase people. Carnage also summoned his henchmen during the plot of the Maximum Carnage maze. The Marvel idea was unfortunately used only once at Halloween Horror Nights, as the maze was a failed concept.
