Biff Tannen

Biff Tannen is a fictional character in the Back to the Future trilogy. Thomas F. Wilson plays Biff in all three films as well as in the Back to the Future: The Ride, and voiced the character in the animated series. Aidan Cutler played him in the original West End production of the first film's stage musical adaptation, and Nathaniel Hackmann plays him in the Broadway production. Biff is the main antagonist of the first and second films, while his great-grandfather, Buford "Mad Dog" Tannen (also played by Wilson), serves as the main antagonist of the third film. Biff is portrayed as a hulking, belligerent, dim-witted bully who obtains what he wants by intimidating others into doing his work for him, or by cheating. He and his family members are shown to misuse idioms in ways that make them appear foolish and comical, despite their intention to insult or intimidate. He frequently calls others "butthead". Biff's appearance as a corrupt, ostentatious gambling magnate in the alternate timeline of Back to the Future Part II later drew comparisons to casino owner Donald Trump. Writer Bob Gale said in 2015 that Trump had influenced the character, although Snopes noted that neither Gale nor director Robert Zemeckis had previously mentioned such an influence in the preceding 30 years. The character is named after studio executive Ned Tanen.
