Shape-changing aliens which arrived hundreds of years ago on Earth. After sending a distress call, their leader, Broton, learned that their homeworld had been destroyed in a natural disaster who first appear in Terror of the Zygons.

He suggested that the Zygon fleets come to Earth and although it would be many hundreds of years before they arrived, he planned to terraform Earth in preparation.

The Zygons brought with them a Skarasen which supplied them with the nutrients they needed to survive. By the late twentieth century, Broton was ready to begin his plan.

He replaced the Duke of Forgill, an important local to the people of Tullock, as well as being on the board of the Scottish Energy Commission. This gave him access to the World Energy Conference, to which he planned to lure the Skarasen and use it to destroy everyone inside, throwing the world into panic and confusion.

The other Zygons also impersonated Tullock locals. One, Madra, briefly impersonated Harry Sullivan but was killed trying to attack Sarah Jane Smith.

The other two impersonated Sister Lamont from the hospital and the Duke’s ghillie, known as the Caber. They were blown up when The Doctor activated the ship’s self-destruct mechanism, while Broton was shot by Brigadier Lethbridge-Stewart.

In the early 21st century, the Zygons that were frozen in 1562 woke from their stasis cubes and infiltrated UNIT, gaining access to the technology in the Black Archive. Kate Stewart set off a nuclear device beneath the archive. Before the countdown reached zero, the Tenth, Eleventh and War Doctors temporarily erased the memories of the original Kate, Osgood and McGillop, as well as their Zygon impersonators causing them to forget which ones were real and which was Zygon. Both Kates cancelled the detonation, and the humans and Zygons were able to create a peace treaty between them. When no one was looking the Zygon copy of Osgood slipped the original’s inhaler back to her. (The Day of the Doctor)
Some years later, a rebel faction of Zygons, led by Bonnie, began to undermine the ceasefire. Bonnie had taken the form of Clara Oswald, and was determined to expose the 20 million Zygons living on Earth and find a land of their own. (The Zygon Invasion)

Zygons were able to produce electricity bolts from their hands that could knock out other species. They could also kill enemies by turning them into piles of wires, that sparked with electricity. (The Zygon Invasion)

They were gained the ability to forge a telepathic link with someone and take the form of a loved one from their memory. (The Zygon Invasion)

A Zygon was captured by the Twelfth Doctor and Osgood.

Under a Zygon base in Turkmezistan, this Zygon attacked The Doctor while he was rescuing Osgood from her chains with his sonic sunglasses. However, a cave-in trapped the Zygon, prompting the Twelfth Doctor to secure it and bring it aboard Boat One, where it was questioned. It refused to tell The Doctor its name but revealed the Zygons’ new intention: to rule the world. (The Zygon Invasion)
