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.
Wolverine is helpless even against Spider-Man's webs. Spider-Man's webs are twice as durable as steel. This means that Wolverine, which has a lifting force of 1-2 tons, is well above the level that it can be saved. The Spider-Man, on the other hand, has a lifting capacity of up to 25 tons. Even if Spider-Man can't kill Wolverine with pure force, he can kill him very easily by strangling him. Wolverine has been killed in this way many times before. Not to mention the fact that Wolverine can't touch Spider-Man because of Spider-sense.
