Rakkonoids were a race of galactic techno-thieves. They had green skin, pointed dome heads, big yellow eyes and antennae.
In the year 5,000,000,000, a group of Rakkonoids attacked an astro-race to bring Skip Pyleen on board their ship. He had offered to sell them the secrets of the Hyposlip 500 lightspeed podule technology. The Tenth Doctor discovered the plot and piloted the ship to the authorities, who arrested Skip and the Rakkonoids. (COMIC: Death Race Five Billion)
