Brelarn

Brelarn was a Warlord of the Zygons. He and a group of Zygons crashlanded on the planet Earth around the start of the 20th century with two Skarasens.

He served as the Zygon commander during their plot to defeat the Human race and turn Earth into a new Zygor. Some of the Zygons felt this was too risky but he felt the risks needed to be taken. He personally thought up the scheme of of killing King Edward VIII, and when world leaders attended his funeral capturing them in order to take their Body Prints. Brelarn took the form of the dog Teazel and mauled three Zygons to death for mutiny. After Teazel escaped his reverted form changed back to its original Zygon form. He attempted to stop the Doctor subduing the Skarasen. The Skarasen sighted his master and angrily ate him whole. (TDA: Sting of the Zygons)
