[[WMG: The Martian Rats used to be a slave caste for the Mice before the Plutarkian invasion]]
Ever wondered why the Rats in the original series worked for the Plutarkians and remained such even after their masters' defeat?
* Good theory. It would also explain why Modo objects so much to being called a rat.

[[WMG: The Martians are the descendants of the mutated survivors of the [[Franchise/SailorMoon Silver Millennium]], and venerate Sailor Mars as a goddess]]
I just love the image of Sailor Mars on a bike leading an horde of Biker Mice into battle.
