She-Hulk, Meggan (transformed), Captain Marvel in Binary form, Tarene the Designate, Gaea (if she counts), and Jean Grey in Phoenix mode (if she counts) are all above the class 100 limit. As are Hope, Geiger, and Rogue when copying the right powers. Valkyrie can reach this level when in Disir form, but then she turns into a villain. Danger is exactly class 100, as is Red She-Hulk, but she can go well beyond that if she absorbs enough energy. Hippolyta is probably currently around the same level, as is Ardina. UltraGirl might have the potential to evolve to class 100, but is currently class 50.
