3-D was one of the three high school boys who made up Biff Tannen's gang in 1955.
He got his nickname from a distinctive character trait; "3-D" was always wearing a pair of cardboard 3-D glasses with red and blue lenses, which were worn in theaters when watching three-dimensional movies.
Behind the scenes
3-D was portrayed by Casey Siemaszko.
He was never referred to by his real name or his nickname. His nickname is only given in the films' novels, screenplays and credits.
