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.
1. That was mindless hulk, not our savage one.
2. Hulk expolited gladiator's weakness to radiation and used a nuclear reactor to defeat him.
3. When gladiator was taking hulk to space, hulk said he had three seconds to do something before gladiator takes him to space. Taking gladiator's speed which is 100 times the speed of light into account, he would have literally taken less than nanoseconds to take hulk to space. Some nerfing of Gladiator speed here as usual.
