Mirana

Mirana was Officer 274 of Earth's Interplanetary Police.

Biography
Mirana's mother and father came from the GalSec colony. (AUDIO: Project Infinity) She became a police officer with Interplanetary Police (AUDIO: "Death to the Daleks!") and, during the Second Great Dalek Occupation, was robotised by the Daleks. As an unwitting Dalek agent, (AUDIO: Project Infinity) she pursued Alby Brook. Upon finding him, they fled from the Daleks together to Yaldos. (AUDIO: "Death to the Daleks!")

On Yaldos, the Dalek Emperor linked with Mirana and had her shoot Kalendorf, but he and the Seer of Yaldos were able to free her from the connection, leaving her in a coma for five months during which she was cared for by Dr Johnstone. Upon awakening, she utilised her Roboman implant to supply her allies with the coordinates of the Daleks on Lopra Minor but was ultimately captured and taken with Alby and Kalendorf to become Daleks. (AUDIO: Project Infinity)

The trio were awoken by the Mentor and joined her and the Alliance Daleks, with Mirana becoming captain of the Defiant. After six years of the Enemy-Alliance Dalek War, she helped rescue Susan Mendes and explained what happened during her sleep. (AUDIO: Dalek War: Chapter One) When Enemy Daleks took over the Defiant, Mirana realised that Morli had been brainwashed by the Alliance Daleks and escaped with Marber in an escape pod (AUDIO: Dalek War: Chapter Two) in which they died from asphyxiation. (AUDIO: Dalek War: Chapter Three)

The escape pod was found by the Alliance Daleks long after Mirana and Marber died. The Mentor kept the pod to prove to Kalendorf that Mirana was dead, which she told him many years later at the conclusion of the Dalek War. (AUDIO: Dalek War: Chapter Four)

Behind the scenes
As stated by Nicholas Briggs in Dalek Empire: The Scripts, Mirana was originally supposed to die in Project Infinity but survived due to the strength of Teresa Gallagher's acting.
