Another interesting thing, is that DC's powerscales use their own weird system.
Typically written, 12 is the top.
For example, Brainiac , one of the smartest beings in the universe, is classified as a 12th level intelligence. Brain smokes even the most advanced computers, complete combined knowledge of untold countless civilizations in history, etc.. I imagine the only things above him, would be something nearing complete omniscience and complete omniscience.
Batman, is a 12th level fighter. One of the best combatants in the universe, able to hold his own in most any situation against any enemy, mastery of all the world's martial arts, and mastery of nearly every form of combat to boot.- trained marksmen, strategist, etc etc.
Karate Kid, is 15th level.
By scale, nearly an omnipotent level of martial arts skill.
