Natasi Ashia (D20)

Natasi Ashia (Caprica Six) is one of the central characters from Allen Knott's Battlestar Galactica: Betrayal series. It is due to her religious epihiany that humanity is worth saving that this series of events leads to the first Cylon Civil War also known in this reality as the "Betrayal War".

Natasi is based on the canon character of Caprica Six (D1)

Betrayal
Natasi betrayed the Cylons in order to save humanity (most especially her romantic partner, Gaius Baltar), because she believed it was her final God-given mission. To wage a rebellion against her own kind, she recruited several other humanoid Cylons into her plan. Including most notably Gina Inviere

'Notes
