If Taylor does have Marvel Comics Thor abilities all I will say is YIKES. 100+ ton lift capacity (Index of the Marvel Universe puts Thor at Class 100 Strength) puts her at Brute 9 EASY. Throw in Mjonir which is Striker 9 plus a blaster 9 subrating because she can throw the sucker PLUS Shaker at least 10 (Weather Control; I say 10 because Thor can call down REAL lightning).
It doesn't work that way.
You can't say she can list X mass that makes her Brute 9. Able to lift 100+ tons could be as low as Brute 4 depending on other details(not that I think that's the case here), Mjolnir doesn't give her a striker rating, not unless you can point to some exotic effect Taylor can apply to other people or objects but needs to touch them to apply it (and no "smashing to pulp" isn't an exotic effect that gets a striker rating).
I agree about the high level shaker and some blaster rating although unless I'm missing something I think Blaster is much too high as most of the effects will be folded into the shaker rating. Also producing real lightning isn't that impressive, if that was the extent of her weather control I wouldn't call it more than shaker 4-5 at most. She can produce comic book lightning, i.e control how much power it does, control exactly where it goes(even if that's right next to a lightning rod or needs to travel around three corners to reach it's target) plus very localized (or not if she wishes) winds enough to flip over vehicles, etc... so I agree her weather control could earn her a shaker 9 if she's not stupid about how she uses it, although so far she hasn't realized she can do it.
Blaster 5-8 Is an option, Thor's lightning while powerful, is not capable of destroying cities.
Thor doesn't have a striker rating, his/her hammer is brute.
Shaker 6-8 for the weather control. (Mainly cos it can be called down anytime, anywhere)
1)Weather control can definitely destroy cities.
2)Ability to destroy cities is not a requirement for any level of blaster or shaker.
3)I can see her getting either a very high shaker OR a very high blaster level depending on how she uses her powers once she figures it out, but not both.
Actually thinking about it she might get labeled a Brute/Mover/Shaker/Master with no blaster rating, given that the hammer can move on it's own and her lightning would be folded into the blaster rating.
Of the individuals in Brockton Bay, my guess would be three possibilities. Panacea, Miss Militia and Vista. Panacea might qualify, but she might need some psychotherapy first. Miss Militia might since she really, truly believes in her duty as a Hero. And Vista is a cheating cheater who cheats by lifting the space around the hammer rather than the hammer itself.
While this story seems to be using comic book "worthy" definition I can't help but wonder who would be worthy according to the Mythological Thor standards, Hookwolf and Grue both seem likely, as does Armsmaster and canon Skitter.
