Biff Howard Tannen is a fictional character in the Back to the Future trilogy.
He is the main antagonist of the first two films, and a villainous lesser character in the third film.

Biff is portrayed as a towering, violent and aggressive bully who obtains what he wants by intimidating others into doing his work for him, or by cheating.

As the films' important October 2015 date approached, commentators began noting the similarities between the older version of Biff Tannen and then presidential candidate Donald Trump.

When the comparison was brought to writer Bob Gale's attention in an interview, he stated that elements of Tannen's personality were actually based on Trump, who was already well known in the late 1980s for his work in real estate and tabloid controversies.
