Marvel fans know one thing for sure when it comes to Thor’s mystical hammer Mjolnir: Only he or she who is worthy may lift it. However, Thor #7 is now out, and apparently Marvel Comics is making some major changes to Thor’s hammer, and how it works. (SPOILERS) As we learn in the latest chapter of Donny Cates’ Thor storyline, Thor has sent Mjolnir back to Earth to perform a little test. The King of Asgard has felt for some time that something is amiss with his realm and powers, and he gets some big confirmation when a random Earthling is able to wield Mjolnir!
