Susan "Suz" Mendes was a human geologist who was used by the Dalek Emperor to give hope to the other slaves, earning her the nickname of the "Angel of Mercy" during the Second Great Dalek Occupation. After bringing about a rebellion and sharing her mind with the Emperor for a time, she caused the Great Catastrophe and became the Dalek Supreme.
Suz was born on Vega VI where she lived with her mother and father (AUDIO: Invasion of the Daleks, Dalek War: Chapter One) and was regularly sent pickled onions by her grandmother, who lived on Earth. (AUDIO: Invasion of the Daleks, Project Infinity) She was only vaguely aware of the Daleks from history lessons, the last war against them being centuries before her birth.
Becoming a geologist, Suz worked as a researcher for the Reinsberg Institute and was sent in search of rare mineral deposits (AUDIO: Invasion of the Daleks) for Project Infinity, of which she was unaware. (AUDIO: Project Infinity) She developed something of a relationship with Alby Brook, her regular water taxi driver. (AUDIO: Invasion of the Daleks)
The Dalek occupation
When the Daleks invaded Vega VI, Suz refused to flee the planet with Alby and went looking for her family. She survived the invasion and was, like the other survivors, forced to mine veganite, her defiance in saving Kalendorf - whom she befriended - bringing her to the attention of the Dalek Supreme. The Dalek Supreme had an audience with her and agreed to give the slaves food and rest, later telling her to come up with a work/rest rota to give the people hope. (AUDIO: Invasion of the Daleks)
Suz spent six months travelling between Dalek-occupied planets bringing hope to the slaves through similar means, telling the Dalek Supreme that she needed Kalendorf as a companion to keep her going and secretly having him deliver telepathic messages to the slaves telling them to stand by for rebellion. She began to feel a sense of accomplishment for what she was doing and became known as the Angel of Mercy.
When rebellion began early on K5000, Suz sold Wernay and the rebels out to keep her and Kalendorf's secret, further appalling her companion with her apparent pro-Dalek leanings which she began to recognise. The Daleks made her watch the Earth Alliance's attack on Guria and allowed her to see Alby for a brief moment through vid-link, later being probed by the Dalek Supreme on what he meant to her. (AUDIO: The Human Factor) She was left shaken by this experience. (AUDIO: "Death to the Daleks!")
Years later, Suz was forced to stop the Zalerians from fighting the Daleks, who returned to Spiridon to reawaken their army and make them invisible. When threatened with an Ogron, she confessed that Kalendorf was likely amongst the rebels and urged the Daleks to exterminate the Seventh Doctor to save Kalendorf and Skerrill from his destruction of the army before being taken to complete a new assignment. (AUDIO: Return of the Daleks)
On Celatron, Suz realised that she had no real power over the Daleks after attempting to refuse to obey any Dalek but the Dalek Supreme and a Dalek Supreme Controller exterminated her Celatron assistants before her eyes. She declined the offer of having Kalendorf killed and replaced with Alby and, (AUDIO: "Death to the Daleks!") having realised that she was a collaborator, (PROSE: Suz) formed a link with the Seer of Yaldos so that her memories and knowledge could live on. (AUDIO: Project Infinity) Following a meeting with the Dalek Emperor, she incited rebellion by shouting "death to the Daleks!" on a live broadcast (AUDIO: "Death to the Daleks!") and was paralysed and taken away.
Transmatted to a ship in orbit, Sysan was put in stasis to become a Dalek at some point in the future. (AUDIO: Dalek War: Chapter One) Unbeknownst to her, the Dalek Emperor had transferred his mind into hers to escape the Mentor and her Daleks. (AUDIO: Dalek War: Chapter Two)
Sharing a mind
Almost six years later, the Mentor found the ship and ordered that Suz be destroyed in order to kill the Dalek Emperor inside her mind. She was saved by Alby and awoken by Mirana and Dr Johnstone, who informed her of what had happened during her slumber, how she had survived and that, in early days of the Enemy-Alliance Dalek War, the Dalek Emperor likely transferred his mind into her. (AUDIO: Dalek War: Chapter One)
Aboard the Defiant, the Daleks demanded that Suz be handed over to them so that the Emperor might be restored. She agreed to go with them, threatening to kill herself unless her friends' lives were spared, and was reunited with Alby before being scanned by the Daleks and briefly taken over by the Emperor. (AUDIO: Dalek War: Chapter Two)
Back in control of her body, Suz determined that the Emperor chose her because Alby would almost certainly save her, meaning that he had weaponised their love. Morli attempted to kill her, but she was saved by the Daleks and later reunited with Kalendorf who told her to make a broadcast rallying people to the Daleks' side against the Mentor's. (AUDIO: Dalek War: Chapter Three) When Alby tried to shoot Kalendorf, who he believed had brainwashed Suz, she shot and killed him.
Suz agreed to go to Earth with the Dalek Supreme to have the Emperor removed from her mind. However, her mind was instead completely erased, giving the Emperor full control of her body. She was briefly restored thanks to Kalendorf's telepathic powers and sent a destructive impulse through the Dalek net, destroying every single Dalek connected to it in what was known as the Great Catastrophe. (AUDIO: Dalek War: Chapter Four)
As the Dalek Supreme
The Dalek Supreme analysed data on the progress of her plans and gave orders to her subordinates. (AUDIO: The Healers) She ordered the capture of Galanar and tortured him before telling him that he had been created by the Daleks, as were the rest of his kind. (AUDIO: The Survivors) She ordered Elaria to win Galanar over to the side of the Daleks and believed that she was successful before realising that she had betrayed them. (AUDIO: The Demons) The Dalek Supreme commanded the destruction of the Ranger 1 when Elaria and Galanar escaped aboard it. (AUDIO: The Warriors)
The Dalek Supreme tortured Siy Tarkov and told him that she had once been human, legitimately asking why humans continue to defy what she believes is a superior race and exposing him to radiation which will mutate him into a Dalek. She believed that she had triumphed in her plan to turn humans into Daleks to attack the Galactic Union and, in response, Galanar gave her a speech about the strength of the human race.
