Thor (Jane Foster)

For many years, Foster was a nurse employed by Dr. Donald Blake, Thor's first mortal host, before becoming a doctor herself. In a 2014 storyline Foster is revealed to be deemed worthy to wield Thor's hammer Mjolnir when the former is no longer able. During this temporary period, she adopts the name Thor, the Goddess of Thunder, and joins the Avengers. This storyline ends with the character sacrificing her life to defeat a dangerous adversary, and the reverting of the mantle Thor to its original bearer.
