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.
If it were a fight (and movie Art) I don't know cause I've never seen MzR
But if was a type of fight where they each had identical problems (like a maze puzzle/trap) Artemis (book) would curbstomp the poor guy and if it were the movie i don't 100% know because his intellect is never really use all that much (but I did stop the movie during the troll fight cuz the move sucked -4/10)
