Zygons, let zygons by zygons
We’ve made it to the end! You deserve a big round of applause for sticking with me this whole month and having to read so much about Doctor Who. Let’s face it, if you’ve been reading all this time and aren’t a Doctor Who fan you’re either my mom or my wife!
One of the few frenemies of the Whoniverse. Sometimes an enemy, sometimes not.
Zygons have the ability to take the form of any human, which is probably works out best for them since they look like walking hamburger meat.
They also shoot stuff from their hands that can knock out their prey, or kill them. Zygomatic normally leave people alive. As long as the person they’ve taken form of is still alive they have a continual feed of information from their brain.
One time when the Zygons tried to take over Earth, they came face to face with Kate Stewart and Osgood from UNIT. In order to work out their differences, Doctors Ten and Eleven altered their consciousness so that nobody knew who was human and who was Zygon anymore.
The current Osgood is at least part Zygon. There’s two of them, and at least one of them is a Zygon. Possibly both. She’s not telling.
