Bigon

Bigon was a Greek philosopher.

Biography
Bigon and other Greeks were abducted by Monarch on his fourth visit to Earth and converted into androids. Bigon was promised that he would rule over Europe once the planet had been conquered, but he rejected this offer, as he believed that democracy was the best form of government. Monarch kept him to provide an element of doubt in his perfect society, because he believed it was an intellectual galvanizer. He aided the Doctor in defeating Monarch, and the androids decided to look for another planet on which to settle. (DW: Four to Doomsday)
