trentonlf: In the comics the male Thor died and now a woman is Thor. It's just Marvel trying to appeal to women, just not sure why they picked Thor as a gateway though.
Actually, male Thor
(the real Thor) isn't dead. He was deemed "unworthy" and was stripped of his hammer, his title and
(for reasons I cannot understand) his name. Mjornir was given to a female Asgardian who was then dubbed "Thor, God
(dess?) of Lightning". Male Thor, feeling this turn of events was ridiculous, has taken up a mighty, enchanted axe called
Jarnbjorn in replacement of his former weapon and is working to try to clear his name and reclaim his rightful place in the Asgardian Pantheon.
TL;DR - Comic books.
