Auntie (Three's a Crowd)

Auntie was the leader of a human colony ship in the 29th century.

Biography
Forced by threats from the Khellians, Auntie gave them some of the colonists aboard her ship as food. After the Fifth Doctor arrived on the ship and fought against the Khellians, Auntie helped the Doctor activate the self-destruct of the colony ship that killed most of the Khellians. The leader of the Khellians, Makra'Thon, swallowed Auntie while he was hunting the Doctor. While in his stomach, Auntie activated an explosive device that killed Makra'Thon. Auntie then led her people to colonise a planet. (BFA: Three's a Crowd)
