Dalek-Cyberman War

The Dalek-Cyberman War was a war between two evil races, the Daleks and the Cybermen, that occured on Earth. The war started when Dalek Sec badmouthed the Cyber-Leader and started a war, but it didn't go well at first because Dalek Sec obviously can't count to four, let alone five million. Despite being massively outnumbered, the Daleks kicked the Cybermen's metal asses and eventually whupped them so much that they considered retreating to another universe simply to get away from the terror that they had unbottled. Not only that, but the Daleks called reinforcements and soon the whole planet was aflame with Daleks and Cybermen engaged in combat all over the world.

In the end the conflict got so out of hand that the Doctor, the last remaining Time Lord, sought the help of The Demon of The Abyss who opened a portal and sucked all the Daleks and Cybermen into the void between worlds.

Despite this, the Cult of Skaro managed to escape to New York in the 1950s, where they began some experiments on pigs that got a little out of hand.
