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 3-dimensional movies.

In the alternate 1985, he is seen still working for Biff, along with Match and Skinhead. On this occasion, his glasses are not cardboard; instead, they are aviators which have blue and red lenses like his old 3-D glasses.

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.
