Biography
Somehow, Vaughn got into contact with the Cybermen, formed an alliance with them, and then masterminded an invasion of Earth, in return for a large amount of power. However, these plans fell apart when the Cybermen betrayed him. Allying himself with the Second Doctor, and, using an invention that inhibited extra-strong emotions deadly to Cybermen, he helped the Doctor to defeat them. He was killed on the rooftop after being shot by a Cyberman. (DW: The Invasion)

At the moment of death, Vaughn's consciousness was transmitted via satellite into one of fourteen identical robot copies of himself. Over the years, he influenced and manipulated humanity's development. He invested the remains of International Electromatics' empire into new technologies, such as the BOSS supercomputer, the development of the Time Scoop, and Professor Kettlewell's inventions. (DW: The Green Death, Invasion of the Dinosaurs, Robot) As the Cybermen repeatedly attempted to invade Earth, Vaughn bought pieces of their technology in order to repair his failing body with what was left of his money.

In the 30th century, Vaughn encountered the Seventh Doctor. Vaughn captured the Doctor, hoping to learn the secret of time travel from him. The Doctor trapped Vaughn in the TARDIS, preventing him from transferring his consciousness to another body. The Doctor later removed Vaughn's brain crystal and installed it in a food machine.
