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.

But his doujutsu alows him to shrink anything (only not living creatures besides him)
He can shrink himself
or even open a portal to dodge her attacks
His skills with Black rods will not work on her too..
She had an insane healing factor (resisting even to gungnir)
He has alot of strenght feats ..
But i think she is strongher
Conclusion : He wins... He doesn't need to kill her.
(He has Daikokuten which allows him to store objects or "people" in an alternate dimension... The Daikokuten dimension is a pocket dimension where time doesn't flow, meaning objects or people stored there are essentially frozen in time... SO he doesn't need to kill her, he just needs to store her in the Daikokuten dimension)...She couldn't even teleport to Asgard... imagine leaving Daikokuten dimension (impossible).
