Davros the great healer
The TARDIS has landed on Necros, the location of the funeral home Tranquil Repose. The Great Healer of Necors is exposed as none other than Davros who is using the organic material in the cryogenic storage units both as the raw material for the synthetic food that is Necros's biggest export and also to create a whole new army of Daleks with which to take control of the universe.
