Stallion makes an appearance during Operation: Hollywood and Vain. He is one of the three Hollywood action hero parodies to make appearance in the game and can be controlled by the player to make a stand against Yuri's occupation.
For unknown reasons, Sammy and the other action hero parodies have had their unique dialogue and names replaced by patch 1.001, with all of their quotes replaced by standard GI ones. In this version, Flint is called simply Bodybuilder. The original strings and audio files are still found in the game files.
