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.
Batman will have difficult finding a way to harm the Asgardian regardless of several weeks for preparation.
A human born is just foolish to challenge a warrior born god, in no story or fiction this ends well.
Batman is outmatched and no danger to a god, Thor wins easy.
You cannot stop Thor unless you are of similar power to him, Batman is not.
Darkseid has notable exploits (e.g. radon gas, his pride etc). Thor doesn't anything like that. Unlike the other powerhouses in Marvel like Hulk or the Sentry who have mental exploits, Thor has no such weakness. Tell me what exactly can Batman do?
