An alternative universe in which Jane Foster finds/picks up Mjolnir First!
this is Marvels’ What if series (earth-788)
Well more like Jane Foster with the power of Thor than actual female!Thor.
Earth X had an actual female!Thor.
What If Jane Foster Had Found the Hammer of Thor?
This is Jane as a god. Marvel cannot tell me different.
I just like the idea that Jane is worthy of Mjolnir, and in my headcanon any version of Jane can pick it up.
Also in my headcanon for this story she ends up keeping Mjolnir and Thor just stays happy being Don and they both end up together (because the way the what-if handled it towards the end was awful).
When Jane Foster picks up Mjolnir and becomes Thor.
From What If v1 #10 (What if Jane Foster Found The Hammer of Thor)
Comparison of the original JiM story were Loki makes his first appearance and the What-if story were Jane picks up Mjolnir before Don, and becomes Thordis (who is like a girl version of Thor).
A lot of stuff happens the same (Loki’s plot to get Thor’s attention, Loki’s hypnotizing Thor/Thordis to get Mjolnir, Thordis throwing Loki to Asgard) but there are some very different things too, like Loki’s dialogue with Thordis (he’s more confused and he makes references to Thordis’ beauty now and then) and the fact that Thordis resisted Loki’s hypnotizing when Thor couldn’t and that she managed to avoid chasing Loki around town by just throwing him into space right away.
Yes, Jane Foster is more effective at taking care of Loki than Thor himself.
From Journey Into Mystery #85 and What If v1 #10 (What if Jane Foster Found The Hammer of Thor)
“WTF Thor has a vagina? Aww hell no! You’re not my son! Yeah that’s right! My son must be in Midgard! Can’t do anything about it now so Loki you’re my favorite now!”
Of course the reasoning here was that Don=Thor but the Thor and Don thing has always been confusing really. But in most comics that I’ve read Don has been his own separate entity and like Jane here he’s just Thor’s host when he picks up the hammer.
And Loki is so smirking, and why wouldn’t he? He is the favorite and only son, he is first in line to get the throne of Asgard, and Odin will finally take him to play catch!
