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.
Infinite Versions of Dandy exist in infinite other universes, and all of them are still Dandy.
Even when all infinite universes come to an end (which btw. Dandy himself can cause, thanks to transdimensional particles) - Dandy still exists unfazed in a void, and there Dandy can even become God himself or "The Narrator", if he so chooses.
There's nothing Reinhard can do to counter Dandy's OmniLock. Dandy doesn't even need to "do" anything spectacular to win, he can simply outlast Reinhard.
