The Clockwork Soldiers were giant, clockwork robots that appeared as toy soldiers and were used for patrols in the Land of Fiction. The soldiers were slow and clanky, but deadly and menacing. The light on top of their hats was used as a camera for the Master of the Land to see from his base, but may not have been how the soldiers themselves saw. They lumbered around with rifles tipped with sharp bayonets. Land of Fiction characters could not see them. (TV: The Mind Robber)

Their exact origin is unclear, if they were created by the Master of the Land or the Master Brain. It is also unknown if they worked with the White Robots or if they were simply a different manifestation of the robots, since they don't appear together at any time.
