Karl Windsor is a character who would've appeared in the unpublished novel Final Destination: Wipeout. He is a fisherman and a survivor of a plane crash.
Karl either lived in or was on vacation in Hawaii and attended a beach party where Ravyn Blackthorne had a vision of a private plane crashing onto the beach, killing several people, including Karl. She manages to save Karl and at least five other people: her best friend Kim Rachelle, a vacationer named Brett O'Connel, a young woman named Drew Perkin, a teenage boy named Bobby Fraider, Bobby's girlfriend Mandy Robertson, and an Average Joe named Corey Michaels. After this, he and the others would've been hunted by Death and presumably Corbin Wainwright.
Due to Wipeout's cancellation, it is unknown what Karl's fate would've been.
