Jimmy Gardner is a character from Dark Seed II. Though he is not the main antagonist of the game, he is presented as an adversary of the game's hero, Mike Dawson.
Jimmy was once a straight-A student in school. Ever since dropping out, however, he mostly spent his days in the Pool Hall chalking a pool cue. Mrs. Ramirez paid Jimmy a large sum of money to kill her husband after she found out that he was having an affair with Rita. When Slim finds a love letter from Mr. Ramirez to Rita, he shows it to Jimmy as proof that he killed Mr. Ramirez. Jimmy pulls out a gun and threatens to shoot Slim, but Mike Dawson gets in between them. Mike asks Jimmy if he thinks he can fight him. In typical Mike Dawson fashion, Jimmy knocks him out in one punch before being punched out himself by Jack. It is later stated that Jimmy has been put in a coma, and he is not seen again for the rest of the game.
