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.
During his peak (in my opinion) during the Dark Avengers run, he'd successfully stolen Iron Man's role as director of SHIELD, replace it and the Avengers with HAMMER and his own team and still had the backing of the common people. He lost it all due to self sabotage because the Goblin persona was creeping back.
During the Red Goblin event he was beating Spider-Man however was baited into removing all advantages because in the end, he wanted it to be Goblin's win not Carnage's.
that's my opinion in this
