Dalek Caan

Dalek Caan, although eventually the betrayer of Sec, is a visionary in his own right. He is the last member of the Cult alive and he engineers the destruction of his own race after he rescues their creator, Davros, from the Time War using an Emergency Temporal Shift and goes insane in the process.

He is seen as a prophet by the Daleks, despite his lunacy.
