Kaliko

Captain Kaliko was a human pirate of the oil-rich planet Boukon. She was the captain of the Black Gold, and used her ship to attack Oil rigs and steal their oil. She had a treacherous first mate named Swabb and a skeleton crew, who later betrayed her for Oil Core. She had a data chip for the Infinite, but wasn't going to give it to The Doctor. After the Oil rigs attacked, she escaped in a life boat. She was killed by Baltazar. (DW: The Infinite Quest)
