K1

The K1 Robot is a giant robot who appears in the Season 4 finale of the "Doctor Who Figurine Adventures".

The K1 robot was originally built to do human jobs which were too dangerous and difficult for humans, such as mining and activities involving radioactive materials. It was built from what was described as a "living metal". Its original intention was to protect humans. If it ever killed anyone, it would become confused.

It was originally found by Morbius after his team lost a "Survivor" style tournament. Morbius used it to slaughter many humans who he convinced were enemies of man. Eventually, Morbius ditched the robot in favor of a Cyberking. Confused, The K1 Robot was found by the Doctors and persuaded that Morbius and the Cyberking were the true enemies of man. After absorbing a large amount of energy from the TARDIS, the robot grew as big as the Cyberking and the 2 metallic titans fought.

Just when it seemed like the Cyberking was winning, the K1 robot released its secret weapon: a virus which dissolved metal. The virus ate away at both the Cyberking and the K1 robot until they disintegrated.
