This marks the first time a female will yield Thor's mighty hammer, Mjolnir. She will make her first appearance in the new, relaunched Thor comics this fall. Many are speculating this is hinting a replacement for Chris Hemsworth in the Marvel Cinematic Universe as a lot of comic events have served as a precursor to film events.
Writer Jason Aaron released a statement warning readers about this new woman:
"This is not She-Thor. This is not Lady Thor. This is nor Thorita. This is THOR. This is the THOR of the Marvel Universe, but it's unlike any Thor we have seen before."
The current Thor is apparently being named "unworthy" and will be replaced as the classic God of Thunder we all know. In replacement of Mjolnir he will be equipped with a giant axe called Jarnbjorn.
