The Doctor (TARDIS Cam)

An ever-elusive and unknown incarnation of the Doctor travelled in his TARDIS to many locations and planets. He often never left his TARDIS. He travelled alone. (WC: The Moonscape, et al.)

He travelled to a wrecked planet with destroyed cruisers and dead Cybermen. (WC: The Moonscape) He also visited a Submarine base that had a dead Dalek aboard. (WC: The Submarine Base)
