Don Chaney

 was a boss of a crime rig in 1938 New York City. He found some extraterrestrial guns, and planned on selling them to the highest bidder. One of his minions, Mouse, was selling them behind his back so he had him killed. He then had the Eighth Doctor and Glory Bee kidnapped and taken to his lair in the Brooklyn Bridge. They escaped, but then the rightful owners of the guns, the Laiderplacker, arrived. He took the Doctor and Charley to CBS, so the Doctor could trick the Laiderplacker. (AUDIO: Invaders from Mars)
