Skip Pyleen

Skip Pyleen was an astro-race pilot in the year 5,000,000,000. During a race in which he used a Hyposlip 500 lightspeed podule, he was apparently attacked by a group of Rakkonoids and brought on board their ship. The Tenth Doctor followed him and learned that Skip was actually trying to sell the Rakkonoids the secrets of the Hyposlip-500 technology. The Doctor locked them in a room and piloted the ship to the authorities, who arrested Skip and the Rakkonoids. (COMIC: Death Race Five Billion)
