Clara Oswald

Oswin Oswald was a human on board the Alaska which crashed into the Dalek Asylum.

Biography
She initially tried to escape the Asylum but was found and converted into a Dalek. Unlike other members of the Alaska, who were partially converted by the nanocloud, she was fully converted, due to her intelligence. In Dalek form she created a dream world for her human mind to dwell in to forget the truth. Under this life, she assumed that she was surviving on souflés and hacked into Dalek systems.

A year later, she aided the Eleventh Doctor, Amy and Rory in finding safe passage. The Doctor attempted to rescue her, but realised she was a Dalek. She wiped the memory of the Doctor from the Daleks' memories.

Oswin raised the Asylum's defenses so the Parliament of the Daleks could destroy the planet and the Daleks committed to the Asylum. (DW: Asylum of the Daleks)
