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.
Yeah the Scarlet King's battle with the Brothers Death caused all of creation to burn to ash.
The Brothers Death had to summon every single soul that had ever died all across every multiverse, iteration and reality to even stalemate the Scarlet King. They where literally panicking and only delivered the last strike whilst the majority of the fight was done by the Tzadikim Nistarim with the Scarlet King's own seven spears.
Also, the Scarlet King fought Isabel Wondertainment who can interact with SWANNS. Scarlet King was actually very powerful that Isabel Wondertainment had to assemble a team of equally very powerful characters.
If her assistant Emma didn't manage to steal one of his spears, they wouldn't have been able to hurt him.
