Austin Marks is a minor character in the Twilight Saga. Austin is best friends with Ben Cheney, and the older brother of the freshman whom Bella Swan asks if she can buy his old motorcycles in New Moon. He lives across the street from Ben.
Austin starts to sit with Bella’s friends sometime during her “dark period”–she first describes him as “older brother to the boy with the motorcycles” but cannot recall when he joined their lunch group. Austin catches the flu the same time as Angela and Conner and can't join them on movie night. Bella buys two busted-up motorcycles from Austin's little brother when she decides to take dangerous activities to hear Edward's in her head.
Austin's only physical feature is his sandy hair.
Austin is noted to share Ben's interest in comic books, action movies, and indie rock music. He also likes outdoors activities.
