Thomas was the pre-war bowling league champion at Beaver Creek Lanes in 2075 and 2076. At an unspecified time he was deployed for naval duty as a private first class out of Hawaii. The other employees and league members at Beaver Creek Lanes threw a going away party for him, which he eventually found out about prior to the celebration. The destroyer he was on was destroyed in April of 2077, but he survived with grave injuries. He was honorably discharged from the military, but a spinal injury stole his ability to walk and potentially his ability to bowl.
This prompted employees at Beaver Creek Lanes to craft a bowling ball launcher (The Striker) to aid Thomas with his physical inability to bowl as well as a temporary ramp for his wheelchair.
In the single message he wrote on the terminal at Beaver Creek Lanes, he lists his title as private first class, despite the US Navy not having a private first class rank. However, it is possible that he was part of a Marine detachment assigned to a ship.
