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. Harming Hela, who was able to easily shatter MjĂžlnir, which was forged in that neutron star you're trying to ignore.
2. Easily defeating Sakaar Hulk, who staggered Surtur, something that Hela was also able to accomplish.
3. Creating a massive thunderstorm over Wakanda, which was calculated to be country level.
So not only does Thor have a country level feat, outshining everything Kara has ever done, he has two feats showing that his attack potency is comparable to his durability. And until you show some proof that Reign is small planet level, I'm not accepting that (it's still less than Thor's feats of harming Hela and clapping Hulk, btw). Thor is stronger. Get over your blatant MCU bias and accept that.
PROVE IT!!!
