Monarch (Four to Doomsday)

"One only harms what one fears"

- Monarch

The Monarch was the ruler of the Urbankan race. He was obsessed with discovering the secret of faster-then-light travel. He believed that by doing so he would go back in time to the creation of the Universe and meet God, whom he believed would be himself.

Monarch first left Urbanka circa 55,500 BC and arrived at Earth circa 35,500 BC, where he abducted Kurkutji and other Australian aborigines. Returning to Urbanka circa 25,500 BC, he returned to Earth circa 15,500 BC, where he abducted Villagra and other Mayans. Returning to Urbanka circa 10,500 BC, he returned to Earth circa 5500 BC, where he abducted Lin Futu and other Chinese people. Returning to Urbanka circa 3000 BC, he returned to Earth circa 500 BC, where he abducted Bigon and other Greeks. After returning to Urbanka for the last time in 731, he began his final journey to Earth, which he planned to colonize with his people- having reverted the entire population of his planet, along with every native of Earth he'd taken from his previous visits, into elaborate silicon chips, which allowed him to store over six billion sentient beings of approximately human size in one spaceship-, intending to approach Earth with a message of peace and goodwill, and then release a poison against humanity that would, in his own words, release them from 'the great tyranny of the universe- internal and external organs', along with all the various other factors that went with that, such as the need to sleep, rest, eat, drink, and so on.

Eventually, only four days away from Earth in 1981, Monarch ran into the complication of the TARDIS materialising on board as the Fifth Doctor was trying to get his companion Tegan back to Heathrow. Meeting the leaders of the four ethnic groups on the ship, The Doctor quickly befriended Bigon, the only leader who hadn't been won over by Monarch offering to make him leader of his 'group' on Earth; as a philosopher, Bigon felt that democracy was the only civilised form of government, but fail-safes in his android body had stopped him rising up against Monarch in the past. While The Doctor tried to figure out a way to stop Monarch, Tegan attempted to take the TARDIS to Earth to warn everyone, but only succeeded in materialising outside Monarch's ship in the vacuum of space, while Nyssa was taken to be turned into an android... and Adric, won over by Monarch's vision, agreed to convince The Doctor to let Monarch inside the TARDIS.

The Doctor was eventually able to convince Adric that Monarch was lying to him; all he needed Adric for was to convince the people of Earth, organic life-form to organic life-form, that he wasn't a real threat until it was too late. The Doctor and Bigon then won Lin Futu, the Chinese leader, over to their side by pointing out that Monarch would never give up control of such a populous people as the Chinese, then winning the other two leaders, Villagra and Kurkutji, over as well. With no other way to get the TARDIS back, The Doctor and Adric were forced to go on a spacewalk to get it back... but, with Adric having been given the only space suit, The Doctor would only have six minutes to get to the TARDIS before he froze to death.

Despite the intervention of Persuasion and Enlightenment, Adric was able to remove their main circuit boards before they could kill either him or The Doctor, and The Doctor eventually got to the TARDIS by throwing a cricket ball at the wall of the Urbankan ship; the ball bounced off and returned to The Doctor's hands, and its momentum carried him to the door of the TARDIS, where he was able to make a short hop back onto Monarch's ship to pick up Nyssa and Tegan. Outraged, Monarch tried to shoot them, but The Doctor hit him with a sample of his own toxin and Monarch's body shrivelled in on itself; as The Doctor had suspected from Monarch's foolish belief that faster-than-light travel was the key to travelling through time, Monarch himself was still at least partly organic, demonstrating just how hypocritical he really was.(DW: Four to Doomsday)
