Jimmy (The Snag Finders)

Jimmy (along with Welding Robot X-5 ‘Bert’), were once the best sanitary engineers in the entire solar system. Jimmy’s bionic rivet gun that was worn on his arm, was capable of punching rivets through reinforced Tritanium until it was damaged and they were forced to take meanial work as snag-finders aboard construction projects like Space Station Alpha in order to fund the repairs needed.

Fortunately for Jimmy the Doctor repaired his rivet gun when it was needed to expel a cobalt bomb (of the Klytode’s design), into space and thereby save Earth from a planned explosion and crash of the space station that would have changed the Earth climate. (DWAM: The Snag Finders)
