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.
"Father and son. That's why Sabretooth always considered Logan "sloppy seconds" to his "original" / "real deal." The other critical element in my presentation of their relationship was that, in their whole life, Logan has never defeated Sabretooth in a knock-down, drag-out, kill-or-be-killed berserker fight. By the same token, on every one of his birthdays, Sabretooth has always managed to find him, no matter where Logan was or what he was doing, and come within an inch of killing him. For no other reason than to remind him that he could".
