Marty McFly III was a possible descendant of Marty McFly and Martin McFly Jr. His existence as the third to carry the name of Marty was dependent on the McFly future that Jennifer Parker witnessed in 2015, as deduced by the following events:

  • George McFly confronting Biff, kissing Lorraine, and becoming a writer
  • Marty McFly getting injured in the car race against Needles

Behind the scenes

As the card game in which this person appears deals with a series of alternate universes, this character cannot be considered film canon.
