Fray'kon was a Kulan. He led a faction on Earth that wanted their species to conquer the planet. They allied themselves with Pierre-Yves Dudoin. Fray'kon killed the head of the pro-conquest faction, Sa'Motta. Arthur Tyler III later killed himself and Fray'kon by ejecting them both out of an airlock, allowing the Eighth Doctor, Fitz Kreiner and Anji Kapoor to escape from a Kulan spacecraft.
