John Lumic

John Lumic was a business tycoon and owner of Cybus Industries and the creation of the Cybermen of his universe. Born in Great Britain (he called it 'the Homeland'), he advanced the entire planet through inventions such as the EarPod.

Lumic suffered from a terminal illness and used a motorized wheelchair as transport. He had devoted his knowledge and fortune to discover a way to make himself immortal. To this end, he used Cybus Industries' front organisation International Electromatics to collect homeless citizens to use as unwilling test subjects towards this end.

His Cyber factory in London upgraded the homeless people into Cybermen. He then began his next plan: to upgrade the whole of London. When Lumic's breathing apparatus was damaged by Crane, the Cybermen upgraded Lumic himself into their leader, the Cyber-Controller. When the factory was destroyed, the upgraded Lumic tried to stop the Doctor and his friend's from escaping but fell from his Zeppelin and was destroyed. (DW: The Age of Steel)
