The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
about maths? Btw, Powerscaling is based on certain frameworks of philosophy, mathematics and physics that provide the structure. Power-scalers using (mathematical concept) as a means to established the scaling for different characters types. But even mathematical concept has defined limits.
Philosophy offers more hypothetical ideas via theological concepts as Apophatic theology reject scaling concepts/ideas, and seen as the best way to scale a top tier character, which represents something completely unsurpassed or suggest a way to conceptualize something truly Boundless.
