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.
Do not listen to the Superman/Kirby stans. They are paid and nobody is oneshotting the other. This is going to be a catastrophic fight. I think this would result in a TIE! Kirby is extremely malleable. You can stretch him in many ways and he is totally fine. He also has the strength to crack planets the size of Earth! If that is not enough for you; Kirby has defeated the embodiment on Negative Energy, not only that but he has defeated Void Termina who is capable of destroying everything up to the 5TH DIMENSION! In terms of speed Kirby can summon the warp star which is faster than light. Also, I am not counting the Super Smash Brothers feats, as they are not canon according to Sakurai (Creator of Smash and Kirby). As for intelligence... Fun fact: Kirby is actually a toddler. Not at his full potential yet. Kirby has a lot more feats... Superman... Is one of the most powerful characters ever, it would take a long time to say all the feats. But if you think Kirby is one shotting superman, clearly you don't know much about this fight. Ik this isn't a well written Oscar nominee argument, but being realistic; There is a good chance they will tie, but if one of of them wins, it won't be without almost losing their life! This is a debate that should be left up to the guys at DC and Nintendo. No fan is gonna be able to figure this itching debate, at least not for a long while. Superman and Kirby would draw. But if I ABSOLUTELY had to choose one, I think Kirby will BARELY get the edge on Superman. Anyways, that's all, thanks! :)
