The Back to the Future film trilogy and subsequent animated series feature characters created by Robert Zemeckis and Bob Gale.

The lead character of the series is Marty McFly. During the course of the trilogy, he travels through time using a DeLorean time machine invented by his friend Emmett Brown. He also encounters the villain, Biff Tannen, in several different time periods and visits his family ancestors and descendants.

Martin Seamus "Marty" McFly is the son of George McFly and Lorraine Baines McFly. Marty travels between the past and the future, encountering his ancestors and descendants. Marty and his friend Doc Brown help restore the space-time continuum while encountering Biff Tannen (or members of the Tannen clan) at various points in time.

Doctor Emmett Lathrop "Doc" Brown is the inventor of the DeLorean time machine. At various points in time, Doc helps Marty restore the space-time continuum and reverse the changes that were caused by time travel.

Griff Tannen has not been a contender in any CBUB matches.
