The Machine Empire is an alliance of several smaller mechanical kingdoms. For a long time the Machine Empire was sidelined from the war between good and evil by brutal infighting as the various monarchs jockeyed for position. Now having reached an accord to resolve the matter at a later time, King Mondo and the Royal House of Gadgetry are free to pursue their planned conquest of key parts of the galaxy.

Where the mind games of Rita Repulsa and the fierce brutality of Lord Zedd have failed, perhaps the cold calculation of King Mondo can succeed. Even if Mondo fails, there is always Prince Gasket and his own ambitious attempts to build an empire that will surpass that of his father. And never forget King Aradon and the other leaders of the Royal Houses that make up the monstrosity that is the Machine Empire as they too seek the pieces they need for complete domination.
