Well, if Harry Potter wields Mjolnir in fanfiction, it would be an absolute power explosion. Harry already has his magic skills from the wizarding world, and adding the power of Mjolnir would make him nearly invincible. He could use the hammer's lightning - based powers along with his spells, creating some really unique and powerful combat combinations. It would also change the dynamic of his relationships. His friends might be in awe, and his enemies would be even more terrified.
In many cases, Thor eventually regains Mjolnir. However, the circumstances and challenges he faces to do so vary greatly from one comic series to another.
Thor lost Mjolnir in the comics because of various reasons. It could be a powerful villain's curse, or a moment of doubt within Thor himself that broke the bond with the hammer. Sometimes, external circumstances beyond his control also played a role.
In this fanfiction, perhaps Thor hits Loki with Mjolnir as a form of punishment for one of Loki's many tricks. Maybe Loki has double - crossed Thor in a plan to take over Asgard, and Thor's only option to stop him is to use his powerful hammer.
It could be argued that Loki is also a kind of protagonist in his own way. Even though he is on the receiving end of Thor's hammer, his actions leading up to that moment are likely what drive the story. His schemes and plots are what cause Thor to react, so in a sense, he is a central figure in the narrative as well.
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.
" The World's Sword " was a novel from another world that was published on Qidian Chinese website. The author was Glimmering Snow. This was a world of swordsmen, and sword aura was the main theme of this world. The story told that the protagonist, Bai Yue, lost her life in a rescue mission, but she received an opportunity from the heavens. She fused with the fox demon, Little Matchmaker, and came to her world. There, he faced the threat of an unknown power and experienced the love and hatred between humans and demons. For the dream of his loved ones, he wielded his sword and shocked the four seas. His sword, Torch Dragon, once said,"In this life, you are my king." He was concerned about Honghong, Yaya, and Rongrong, and had protected them all his life. The novel was still being serialised. The chapter list and the latest chapters could be found on Qidian Chinese website.
Well, in the fanfic, Spider - Man lifting Thor's hammer might be a sign of a new level of power or respect within the superhero community. It could also lead to new storylines where he has to take on greater responsibilities, like Thor does with his hammer. He might gain some of Thor's powers or a connection to Asgardian magic too. It's a really interesting concept that can open up a whole new world of possibilities for the character and the story.
