Sean Robertson is a student from Lakeview High School who attended the field trip to New York before he became the only student to survive Jason Voorhees's killing spree in Friday the 13th Part VIII: Jason Takes Manhattan.
He is the love interest of Rennie Wickham, and accompanies her throughout the film as she and her peers face down Jason Voorhees first on the S.S. Lazarus, a ship captained by Sean's father, Admiral Robertson, and eventually the streets of New York City.
