Kin (Nothing O'Clock)

The Kin was an individual that was imprisoned by the Time Lords. It escaped after the Last Great Time War. The Kin could effectively duplicate itself through time travel. Wanting to find the last of the Time Lords, the Kin travelled to 1984 Earth and began to legally buy the planet. In 2010, it had created an alternate timeline where humanity was extinct and Earth was legally its property. However, the Eleventh Doctor tricked the Kin into being trapped at the beginning of time.
