We need new categories to the Strength Scale to show higher levels of strength. Characters like Superman, Darkseid and Doomsday need a category like 100,000+ tons to differentiate between them and other Class 100 supers like Captain Atom or Wonder Woman.
It's an outdated and obsoleted page. Besides, the classifications, "Class 100" etc., aren't used by DC (to my knowledge), they're just invented and arbitrary. In many cases, people are just described as "super strong", without a clear limit.
