My multiverse has tier lists based on how many times more powerful than the average person you are. Each tier, represented by a letter, is eight times as powerful as the previous letter. This represents them as being in "a whole nother league". Adding double of a letter is twice as powerful and three of a letter is double the double. For example, CC would be twice as powerful as C, CCC is 4 times, B is on a whole new tier with 8 times, BB is 16 times more powerful than C, etc.
