The Zygons are a fictional extraterrestrial race in the long-running British science fiction television series Doctor Who. They first appeared in the Fourth Doctor serial Terror of the Zygons, where it was revealed that centuries ago, the Zygon homeworld was destroyed in a stellar explosion. A craft escaped and somehow made it to Earth, where it then crashed into Loch Ness. When the Doctor encountered the Zygons, they were led by a warlord named Broton. Broton wished to conquer the world to allow a refugee fleet of Zygons to colonize Earth.

The Zygons have shape-shifting abilities, allowing them to replicate the appearance of another being, but they must keep the subject alive in order to use its body print. This skill was vital in their concealment and in their scheme to seize power despite their small numbers. The Zygons were also accompanied by an armoured cyborg creature called the Skarasen, the lactic fluid of which was necessary for them to feed. Broton planned to unleash the Skarasen (or Loch Ness Monster as it was known) on an energy conference in London as part of a bid to conquer the Earth. The plan was foiled and both he and his crew were killed due to the intervention of the Fourth Doctor and the United Nations Intelligence Taskforce (UNIT), while the Doctor caused the Skarasen to return to Loch Ness. Zygon technology is biological in nature: in essence their ships and equipment are actually alive.

The Zygons are expected to return in the 50th Anniversary special in 2013, as suggested from a photo during filming on the official Doctor Who Twitter account. Tenth Doctor actor David Tennant has stated that they are his favourite monsters from Doctor Who.

The Zygons first appeared in the 1975 series Terror of the Zygons, where they planned to conquer the Earth.
