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.
batman does barely show any strength feats while john wick has lifted killa (a 400 pound 190kg man) with ease
john wick quickdrawed 7 guys before any could react
batman was taken down with a sniper rifle for a couple of second john wick has a dragon breath which would likely do more damage from up close
john wick easily dodged bullets and is an actaul trained assasin being able to kill multiple people with multiple weapons
his durabilty is roughly on par with batman but his endurance is way better being able to fight while getting stabbed, shot, falling from deadly heights and with broken bones while batman had to use venoms bane or whatever the green thing was he used to get back up while john doesnt john is also way better in combat and a headshot would likely incapicate/Kill batman
