Clockwork soldier
From Tardis Wiki, the free Doctor Who reference
The Clockwork Soldiers were giant, clockwork robots that appeared as toy soldiers and were used as patrols in the Land of Fiction. The Soldiers are slow and clanky, but deadly and menacing. The light on top of their hats is used as a camera for the Master of the Land to see from his base, but may not be how the Soldiers themselves saw. They lumber around with rifles that end with sharp bayonets. Land of Fiction characters could not see them. (DW: 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 work with the White Robots or if they are simply a different manifestation of the robots, since they don't appear together at any time.
