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 movie theaters when watching 3-dimensional movies.
Along with Skinhead and Match, the adult 3-D served as one of Biff's bodyguards in 1985A. However, on this occasion, his glasses were not cardboard; instead, they were customized aviators which had red and blue lenses like his old 3-D glasses.
Behind the scenes
- 3-D was portrayed by Casey Siemaszko.
- 3-D screams hysterically when entering Biff's car. It is said that this was mostly improvisation.
- He was never referred to by his real name or his nickname. His nickname is only given in the films' novelizations, screenplays and credits.
