The BBC have confirmed that the Zygons are returning to Doctor Who to join David Tennant for the 50th anniversary special. If anyone recalls the Zygons the classic aliens that David Tennant always wanted to face. He will have to thank his friend – Steven Moffat.

So who are the Zygons apart from being David Tennant’s favourite monster?
The Zygons are a long lived species with the ability to shape shift by matching a captive humanoid’s shape. One caveat, the captive must remain alive for the Zygon to match their body shape.
They first appeared in the Terror of the Zygons. The Zygons home world was destroyed and an escape craft had crashed into the Loch Ness. Several centuries later they encountered the Fourth Doctor, Sarah Jane Smith (Elisabeth Sladen), Dr Harry Sullivan (Ian Martar)and the Bridadier Lethbridge-Stewart (Nicholas Courtney) as UNIT investigates what was had destroyed several oil rigs of the North Sea of Scotland.
