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.
Intelligence to 55 - 60
Combat to 25
Metro Man is nigh-featless in both
There are some statements, art books, spin offs of metro man.
Sure he is wanked but he can get higher then he already is skip to the metro man part(but I disagree with the death ray argument)
Plus there needs to be evidence that the Island level rocket ship or the Atlantic ocean jello thing were designed to take out Metro Man. Because there's no evidence of that.
Also the Country level multiplier is wank too considering there's no proof that Tighten is billions of times weaker than Metro Man, in fact by that logic, I'm billions of times weaker than my dad because I'm made from sperm cells, which are way smaller than dandruff. The smallest pieces of DNA can replicate a human being but that doesn't mean they are way weaker, like Ben Reilly and Spider-Man for example, Ben Reilly should no more be weaker than Peter, but they should still scale to eachother.
I have Metro Man at Town - Small City which is fine.
