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.
Tbh Ice Age Baby has greater meme power over shrek including it's 6ft 10' size, Scrat is literal fiction destroyer due to his desperation of inserting the acorn so as Buck is gag character.
Manny besides agility and hax (like farting or mouth/ear roar) has everything over shrek: strenght, durability, size, range, weapons (tusks are literal weapons), speed, experience, IQ, BIQ.
Also spare me these braindead powerscalings of Shrekverse characters to island lvl, because of braindead calcs. Manny can be scaled as well to scrat who has a lot of Country, continent lvl feats even some solar or multisolar system tier feats because ice age verse reached cosmic lvls unlike shrekverse.
