Jinkwa

First Pilot Jinkwa was a Chelonian. A Fortean Flicker transported his troop to the planet Hogsumm. When General Fakrid was critically wounded, he transferred command to Jinkwa, whom he finally told was his son. Later, when Jinkwa was going to kill the remaining humans on the planet, the Seventh Doctor was forced to put them in a slow time bubble. (PROSE: The Highest Science, AUDIO: The Highest Science)

Romana eventually visited Hogsumm while trying to track down the Fortean Flicker. She was able to safely turn off the equipment creating the bubble and rescue the humans. Jinkwa then died from the injuries he had sustained previously. (PROSE: Happy Endings)
