Susan Mendes

Susan Mendez was a geologist sent to Vega 6 to study a blue rock known as Veganite. In the course of her original investigation she met Alby Brook. (BFDE: Invasion of the Daleks)

Dalek Invasion
When the Daleks invaded Vega 6 she assisted a man named Kalendorf and in turn stopped him from being exterminated by the Daleks.

During the time following the invasion of Vega 6 Susan Mendez came to organise schedules for the slaves of the Daleks to work by, thus saving their lives.

The Dalek Empire
Susan Mendes (friends called her Suz) and Kalendorf worked together, implementing the shift policy throughout the Dalek Empire. Suz became known as the Angel of Mercy.

Sowing the seeds of destruction
As Suz and her friend Kalendorf made their way across the Dalek occupied planets they (mainly through Kalendorf and his telepathic abilities) sowed the seeds of the Daleks' destruction. (BFDE: "Death to the Daleks!")

Susan Mendes' (first) apparent death
Susan was ordered to give a speech that was to be broadcast to the conquered races of the galaxy, telling them that their work efficiency has expedited the Dalek conquest. However, Susan and Kalendorf had ulterior motives for this speech, as they decided that it was time for the revolt that would bring about an end to Dalek rule. On Yaldos, an argument erupted between Susan and Kalendorf on who was to deliver the message, as they knew that such a treacherous act against their Dalek masters would cause them to be exterminated. Kalendorf begged Susan to allow him to deliver the message from a secure location. Susan agreed, and then requested to be alone. Unbeknownst to Kalendorf, Susan requested the help of the Seer of Yaldos where she had her mind psychically linked to the sorceress.

Susan made her speech, telling the slaves what the Daleks wished for her to say. Toward the closing of her speech, Susan announced the one thing that would launch into a galaxy-wide rebellion; "Death to the Daleks!" The crowd repeated those four words like a mantra and Susan's two Dalek guards closed in on her. One was taken down by the rioting slaves, though the second one opened fire, striking Susan down.
