John Lumic was a business tycoon. He was CEO, director and co-founder of Cybus Industries and the creator of the Cybermen and High Content Metal. Born in Great Britain (which he called "the homeland"), he advanced the entire planet through such inventions as the EarPod.
Though he publicly denied rumours of ill health, John suffered from an incurable life threatening disease that made him so frail he became wheelchair-bound. Although what kind of disease it was remained unknown, John had the following symptoms: difficulty breathing, frailness and needing intravenous medication. Even this disease didn't stop him from dressing in an immaculate business suit, complete with a tie. Even though he wore a ring on the fourth finger of his right hand, no explanation is given as to why.
He devoted all of his resources to finding a way to extend his own lifespan. To this end, he used Cybus Industries' front organisation, International Electromatics, to abduct homeless people for test subjects. They were transported to Battersea Power Station, Lumic's factory in London, where they were upgraded into Cybermen. John took strict measures to keep the project secret, even killing Kendrick who threatened to blow the whistle to Geneva.
Hoping to gain government approval for his work, John unveiled the Cyberman model to the President of Great Britain. To Lumic's dismay, the President rejected the project. Viewing the President's decision as a death sentence, John set in motion a plan to overthrow the government. He mailed a pair of EarPods to the wife of one of his employees, Pete Tyler, ostensibly as a birthday present. In reality, the EarPods scanned Jackie Tyler's brain so John could find the security arrangements and passwords for that night. Knowing the President would be among those in attendance at Jackie's party, John dispatched a horde of Cybermen to kill him (along with any other potential dissidents). (TV: Rise of the Cybermen)
Once his life-support system was damaged by Mr Crane, John realised that he would soon die and pleaded with his Cybermen to help him. The Cybermen reasoned that keeping him alive would be redundant, and against his protests, forcibly upgraded him into their new master: the Cyber-Controller.
This Cyber-Controller was similar to his subordinate Cybermen, except his brain was visible and his eyes glowed with blue light. He remained seated in a chair made from titanium alloy, connected by tubing, though he did have full mobility as long as he disconnected the tubing.
His brain housed in a metallic body, Lumic announced that his Cybermen would take control of London before overthrowing the world. Soon afterwards, the Battersea factory was destroyed from the Cybermen exploding due to their emotional inhibitors getting deactivated. This was delaying the Cyberman invasion. The upgraded Lumic angrily tried to stop the Doctor and his friends from escaping in a zeppelin. Before Lumic could reach them, however, Pete Tyler used the sonic screwdriver to cut the rope ladder suspending John above his factory. He promptly fell into the burning wreckage below to his presumed death. (TV: The Age of Steel)
Although John probably died, the Cybermen lived on across the world. The Preachers devoted themselves to dealing with them. The Cybermen crossed through The Void into the Earth of N-Space. Their invasion force of five million Cybermen was defeated there. (TV: Doomsday) A remnant group was also defeated by the Tenth Doctor, seemingly ending the Cybermen. (TV: The Next Doctor) They somehow lived on however, and ventured into space. (TV: The Pandorica Opens)
