Back To The Future: The Ride
Biff has a major role in the Back to the Future ride film. The ride reveals that in 1991, Doc established the Institute of Future Technology (IFT). On May 2, 1991 (which is also the day the ride opened), time travel volunteers from the IFT went back to 1955 to make sure that the timeline was back to normal following the events of the films. In 1955, 18-year-old Biff stowed away in the time machine, and, once in 1991, caused havoc in the institute before stealing the time machine and blasting through time. Doc, with the help of the audience, followed Biff through time in the new 8-seater De Lorean. Biff visited October 25, 2015 (almost the 30th anniversary of the first time travel experiment), the Ice Age, and the Late Cretaceous period, where he nearly perishes in what he dubs a "lava-fall", before being bumped in the back by the eight-passenger De Lorean at 88 MPH and heading back to 1991. Biff was then taken back to 1955, where he belonged, by Doc. He thanked Doc and the De Lorean passengers for saving his life, but promptly turned aggressive again when apprehended by institute personnel.
