Mandy Robertson is a character who would've appeared in the unpublished novel Final Destination: Wipeout.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