Fanfiction often takes creative liberties. It could be that there is a cross - over event that changes the nature of Thor's hammer's worthiness test. Maybe a powerful magical entity in the Harry Potter universe meddles with the hammer's magic. Harry Potter has shown great moral fiber throughout his adventures. His ability to love deeply, his sense of justice, and his unwavering determination against evil could be seen as the 'worthiness' factor by the hammer's magic, allowing him to lift it.
One implication is that it shows the universality of certain values. If Harry can lift the hammer, it means his qualities like courage and selflessness are recognized across different fictional universes. It also blurs the lines between the two worlds of magic, making for interesting crossovers in the story.
In some fanfictions, it could be because Peter has a pure heart. Just like in the MCU, only those worthy can lift Mjolnir. Peter might have proven his selflessness and heroism in a particular situation, which made him worthy enough to lift Thor's hammer.
In fanfiction, absolutely. Fanfiction is a realm of limitless possibilities. It could be that in a particular story, there's a magical spell or some kind of power - up that allows Harry Potter to meet the criteria for lifting Mjolnir. It might also be a part of a grander plot where different fictional universes collide and the rules are rewritten. Writers might use this as a way to explore new character dynamics and create unique story arcs.
Well, in fanfiction, the rules can be bent. Maybe it's because Hermione has a purity of heart and strong will, similar to what's required to lift Mjolnir in the original Thor lore. Fanfic writers often play with the concepts of different universes colliding, so her magic and intelligence could combine in a way that gives her the 'worthiness' to lift the hammer.
One reason could be his pure heart. Harry has shown great courage and self - sacrifice throughout his story, which might be seen as 'worthiness' in the context of Mjolnir.
Vision cannot lift Thor's hammer in the comics. The hammer's magic is very selective, and Vision doesn't possess the qualities necessary to overcome its enchantment and lift it.
In the comics, characters like Captain America and Beta Ray Bill have been able to lift Thor's hammer.
It could be due to a cross - over event. Suppose there was a rift in the fabric of different fictional universes. Harry Potter, being in the wrong place at the right time, stumbles upon Thor's hammer. And because he has a pure heart (which is often a requirement to lift Mjolnir), he is able to pick it up and wield it, much to the shock of both the wizarding community and the Asgardians.
In some comic storylines, Thanos is able to lift Thor's hammer through extraordinary cosmic powers or specific plot devices.
In the comics, Vision was not shown to lift Thor's hammer. The ability to lift the hammer is usually reserved for characters with specific qualities and story arcs that didn't apply to Vision.
