The Doctor will face the mysterious Missy (Michelle Gomez) this series.
Missy is a nightmarish Mary Poppins inspired character who goes by the rather epic name of 'The Gatekeeper of the Nethersphere'.
But we believe this new character might have a big secret of her own.
Tune in on AUGUST 23RD for the series premiere and watch as the action unfolds.
