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.

"Even after all these months, she couldn't make herself entirely believe that actual Jedi blood ran in her veins-not only Jedi blood, but the blood of arguably the most powerful Jedi in history."
> Luke Skywalker and the Shadows of Mindor
"Gillard also reports that the duel will explain how Obi-Wan is able to defeat his protege, even though Anakin has been established as the most powerful Jedi who ever lived."
> The Making of Revenge of the Sith
"This is Anakin Skywalker:
The most powerful Jedi of his generation. Perhaps of any generation. The fastest. The strongest. An unbeatable pilot. An unstoppable warrior. On the ground, in the air or sea or space, there is no one even close. He has not just power, not just skill, but dash: that rare, invaluable combination of boldness and grace.
He is the best there is at what he does. The best there has ever been. And he knows it."
> Revenge of the Sith
"Skywalker is arguably the most powerful Jedi alive, and he is still getting stronger."
> Revenge of the Sith
Anakin has power unprecedented, meaning he is more powerful than Valkorion. This is backed up by him being stated to arguably be the most powerful Jedi of all time, putting him on par with Yoda, who scales to Sidious, who scales above Valkorion. This is also supported by Pre-Mustafar Darth Vader, who is only slightly stronger than Anakin, being stated to surpass all Sith before him and having unparalleled power.
"Palpatine elevated himself to the position of Emperor, and dispatched Vader as his ultimate enforcer. With his unparalleled Force abilities, Vader swept through the Jedi Temple."
