Bonnie (The Zygon Invasion)

Bonnie was the rouge Zygon leader who took the form of Clara Oswald. She originally lived in one of the Zygon colonies, this particular one being located under Clara's block of flats. The Zygons kidnapped Clara, and Bonnie took on her form, pretending to be Clara while she went around England with Jac looking for more clues to the Zygon uprising.

While Bonnie (still in Clara's form) led Jac and some UNIT soldiers into the Zygon colony, she dusted off the Zygon pods in which they were keeping the kidnapped humans. Jac quickly deduced that Bonnie was not actually Clara and that it was the humans that were in the pods. Bonnie ordered her fellow Zygons to kill them.

Later, atop a hill, Bonnie prepared to fire a rocket launcher at Boat One with the Twelfth Doctor and Osgood inside. The Doctor attempted to reason with her over the phone, but Bonnie, depite the Doctor's protests, fired the rocket at the plane. (TV: The Zygon Invasion)
