Biff Tannen
Biff Tannen is a fictional character and the main antagonist in the Back to the Future trilogy, portrayed by actor Thomas F. Wilson in all three films and the Universal Studios ride, as well as in the animated series and stage adaptations. Born on March 26, 1937, in Hill Valley, California, Biff is depicted as a hulking, belligerent, and dim-witted bully who uses intimidation and deception to get what he wants, often forcing George McFly to do his homework and harassing him throughout their lives. He harbors an obsessive, one-sided crush on Lorraine Baines, whom he repeatedly attempts to force into a relationship, and is known for his misuse of idioms, such as saying "make like a tree and get out of here" instead of "leave".
