KaiserIOT aggregated the powers and equipment of supers into five categories. From least to most they are:
- Class S: Possesses no known superhuman abilities.
- Class M: Possesses no superhuman abilities, but controls rare or powerful technology in lieu of superhuman abilities.
- Class E: Possesses minor superhuman abilities not deemed a threat to the world at large.
- Class K: Possesses major superhuman abilities that could potentially be dangerous on a large scale.
- Class X: Possesses superhuman abilities that have the potential to be cataclysmic in nature. Considered highly dangerous.
