Long-time numbers crunchers know that the power scales between different comic book companies are widely disparate, as an example, Marvel Comics has used a 'class' system in the past. (IE: Class 50 Strength is equal to about fifty tons.) While DC Comics has had their top-tier characters having the ability to speed through time, or lift entire planets.
As Alternate Identities takes place in a world that is not guided by any comic book universe, we have an opportunity to establish a uniform scale that does not have any of the problems inherent in combining different worlds.
Accordingly all characters will align with a power standard that places the top-most heroes and villains at a level in excess of 100 tons.
When describing powers and abilities (even those beyond raw strength) it is advisable to use examples to help demonstrate limits, but remember that even the most powerful of individuals will always be classified within this 'beyond 100 tons' bracket, and exponentially higher limits should not be used.
