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.
An obvious feat which is at least Universal.
But thanks to @Tigerking2020 erasing the statistics for Miraculous characters (and of most other characters I added because I'm knowledgeable of what they can do), everyone else here on SHDB keeps on trolling and lowballing the Miraculous franchise as a whole to only Street Level.
Providing evidence with scans and videoclips is beyond pointless here on SHDB, it's always ignored anyways.
BUT!
The flipside of the coin is that I'm also just as free to simply ignore the evidence which would prove that Lucifer scales in fact much higher than "only" baseline universal.
