Growing up in the Republic of Texas, life was hard for little Johnny Sullivan. His family owned a huge ranch, which was constantly in danger from outlaws and cattle rustlers. Johnny had to learn early how to protect the ranch from outside dangers. His father taught Johnny how to use all kinds of rifles and six-shooters. When Johnny Sullivan grew up, he decided that he wanted to be a lawman like Wyatt Earp or Bat Masterson. He became famous for holding off a whole group of outlaws all by himself with his favorite Shotgun. From then on, all the locals knew him as Johnny 'Shotgun' Sullivan.
