Biff Tann

Biff Tann is a "very respected and influential man" who had recently stayed at the Vault 21 hotel with his wife Charlene Tann.

Background
He purchased a Vault 21 suit during his visit and now regularly talks to his friends at home about it, bragging that "the leather from my Vault 21 suit contains the scent of unwashed ages" and refusing to let anyone try it on.

Appearances
Biff Tann is mentioned only in Fallout: New Vegas.

Behind the scenes
Biff Tann may be a reference to Buford "Biff" Tannen from the Back to the Future series of movies. In the second installment, Back to the Future Part II, a version of Biff became "one of the richest and most powerful men in America" by rigging a series of gambling bets. He also operates a casino known as "Biff's Pleasure Paradise".
