The Foreign Megadeuses come from beyond the sea to attack Paradigm City. The true threat of the 3 megadeuses was worse than imagined. They are revealed to be vessels designed to deliver the components of Big Fau to Alex Rosewater. Carnot contained the head, hips and legs. Robespierre contained the shoulders and midsection (including the cockpit). Fouche carried the arms. The megadeuses were dismantled and the parts for Big Fau were assembled. The discarded parts, slated as scrap, are reassembled to form Bonaparte.
Each of the three foreign megadeuses is capable of unleashing bolts of electricity from the tips of their hands and from their heads.
Carnot could open and close its mouth and use it to crush the enemy or immobilize it.
Carnot was armed with a phonosonic machine, similar to sound weapon seen in Constanze. This device, embedded inside the megadeus, generates phonosonic waves that slowly break apart the enemy.
Robespierre's arms are used as giant drills. These drills can be extended out at the opponent with the megadeus's accordion-like upper arms.
- Carnot: the largest of the three, has a squarish body that contains a sonic based weapon.
- Fouche: has an electrical attack generated from its hands and horn, which can arc to Carnot's hands and Robespierre's horn.
- Robespierre: has drills for arms.
- The Union is a reference to the French Revolution.
