Because of the differences between the arcade and console versions of the games, the designs of the Lee brothers tend to vary throughout the series. While the original arcade game has Player 1 controlling a blond-haired Lee brother dressed in a blue outfit and Player 2 as a brown-haired brother in red, the NES version had their hair and outfit colors switched around: Billy was now the brown-haired brother in blue, while Jimmy became the blond-haired brother in red. "Super Double Dragon" was the first game to have the Lee brothers sport different hairstyles during gameplay, with Billy being given a laid down hairstyle and Jimmy a spiky flat top, a design convention adopted by later games such as "Double Dragon Advance" and the smartphone versions, although some of the promotional art and in-game visuals for the earlier games (such as the ending photograph of ' and the story sequences/character portraits of ') had already depicted the Lee brothers with differing hairstyles. Other games, such as the Neo Geo fighting game and "Double Dragon Neon", depict the Lee brothers as identical twins like in the first arcade game.
