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.
At his peak (returning from Wasteland) Cole was invincible , turned into an avatar with unlimited power, and capable of casually warping an alternative timeline into existence where particular events had not yet happened or had played out differently , with different consequences from what they had in the main timeline.
Even before becoming an avatar, Cole had powers such as casual time travel, dimensional travel, transmutation, teleportation, telekinesis, pyrokinesis, shapeshifting etc I do not even remember the entire myriad of broken magical powers Cole had, other than he'd hax-stomp most opponents easily , and top of all that Cole is also a strong and skilful martial arts fighter (both unarmed as well as with a sword) + ofc the usual superhuman durability all demons in Charmed have (e.g. bullets don't kill them etc).
Cole stomps.
