The Mechanical Monsters were robots created by a mad scientist to carry out his dirty work, such as robbing banks and jewelry exhibits. They are about 10-12 feet tall and extremely resistant to damage, easily withstanding conventional firearms. They also possess astounding strength and the ability to fly using collapsible propellers around their necks. They have cargo compartments in their backs, big enough to easily fit the body of an adult human, and two nozzles on the lower half of their heads which can project flames at least 20 feet.

In their debut appearance there were about 30 of these robots deployed from a hangar in their creator's remote headquarters housing their large central control device.
