Drusa

 was a fighter pilot captain allied with Rassilon in the Dark Times.

She accompanied Rassilon in capturing the Ninth Doctor and Rose Tyler when they accidentally intruded on their battle against the vampires, with Drusa piloting as Rassilon gave commands. Much later, after the Doctor had infiltrated a vampire coffin ship to track down the kidnapped Rose, Drusa captained Rassilon's bowship as the Gallifreyans attacked the coffin ship and the surrounding Cucurbites. She used her special thoracite arrows to kill Hugo who was attacking the Gallifreyan forces and helped seal the victory for the Space Lords.
