There is no uniform scale of power level. We actually have arguments about it frequently, though I personally use an incredibly complex system to grade my characters. There's this 10 tier system, the system Skallagrim explained, and plenty of others between. A character you'd call godly could be less than so on my scale, or greater than. Y'see?

Trying to regulate this sort of thing is difficult because of how everyone sees their own character's abilities, and then the character's personalities come into play. A high tier character whose an incompetent martial artist fighting a character whose physically weaker but significantly better trained? It's totally up in the air. 

The problems that emerge when trying to grade the characters on a scale is incredibly difficult.
