Ivan the Space Biker

Ivan the Space Biker is the nickmame of Gordon Freeman's original model.

Overview
Designed by Chuck Jones, Ivan had a full, wild beard that made him look like a typical biker, hence the nickname of "Ivan the Space Biker". He had a flattop haircut, no glasses, and a grey-green HEV Suit with "Research" written on the back. The beard was heavily reduced to eventually turn into Gordon's stylish goatee. Of note is that he already had brown hair and green eyes. The model, "doctor.mdl", can still be found in the game files.

Trivia
Ivan has a cameo appearance in the web comic Concerned.
