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.
Think of the Crow as: an immortal Captain America (Peak human strength, speed, reactions and agility) with nigh-invulnerability, insane amounts of pain tolerance, immunity to diseases and poisons, that can summon big numbers of crows and has some mental powers (Psychometry and clairvoyance) except he is always bloodlusted.
Then pit him against Ghul.
If you don't want help just ignore :)
