The Greek gods would view Percy in a new light. Zeus might be especially interested and a bit wary, as Thor's hammer has power over lightning, which is also Zeus' domain in the Greek pantheon. Some of the Norse gods, if they were to interact with Percy, would have a strange relationship with him. Thor might be curious and perhaps a bit miffed that a Greek demigod can lift his hammer. Percy's enemies, both Greek and Norse related, would be more afraid of him and might try to find ways to separate him from the hammer.
His relationship with Annabeth would likely become more complex. Annabeth might be both in awe and a little jealous of Percy being able to wield Thor's hammer. She might see him as even more of a hero but also worry that he's getting involved in something too big for them to handle together. With his other friends like Grover, Grover would probably be really excited and see Percy as even more of a protector. The other demigods at Camp Half - Blood might either look up to him more or be a bit intimidated.
Well, if Percy Jackson picked up Thor's hammer in a fanfic, it would be a really cool and unexpected turn. Percy is a demigod with his own set of powers from the Greek pantheon. Thor's hammer is a symbol of great power in the Norse mythology. Maybe Percy would gain some new abilities related to thunder and lightning, like Thor has. He could also face some challenges as the hammer might attract unwanted attention from both Greek and Norse mythological beings who would either be jealous or want to use him for their own purposes.
Thor would probably be shocked at first. His hammer is something very personal and a symbol of his power and worthiness. But then he might see the potential in Spider - Man and be proud that someone else worthy has been able to wield it.
Percy would probably be in awe of Thor's hammer at first. He might try to lift it out of curiosity, just like in the Thor stories where others try. If he couldn't lift it, he'd be determined to figure out why. His friends, like Annabeth, would be more cautious. She'd probably research about the hammer and try to find a logical way to deal with it. Grover might be a bit scared of it, sensing the powerful magic it holds.
In such a fanfiction, perhaps Peter would gain new powers. Since only the worthy can lift Thor's hammer, it would show that Peter has a pure heart and noble character. He might use the power of the hammer to fight stronger enemies, like those that the Avengers alone couldn't defeat easily.
Well, in fanfiction, if Harry picks up Thor's hammer, he might gain the powers associated with it. He could suddenly have enhanced strength, the ability to control lightning to some extent, and be deemed worthy in the eyes of the Asgardian magic that governs the hammer. It would be a really cool twist as Harry comes from a world of magic already, and this would be like adding another layer of powerful magic to his repertoire.
In the fanfiction, if Naruto picks up Thor's hammer, he might gain some new powers related to Thor. Maybe he could control lightning like Thor does. Since Naruto is already powerful in his own right, this could make him nearly unstoppable. He could use the power of the hammer in his battles against powerful foes in the Naruto universe.
In fanfiction, if a human picks up Thor's hammer, it often gives them extraordinary powers. They might gain the ability to control lightning like Thor, or have enhanced strength and durability. It could also lead to them being recognized as a worthy hero, and they may be thrust into adventures in the realm of the Asgardians or on Earth, defending it from various threats.
His relationship with Annabeth would be really different. She would have to adjust to this new form of Percy. At first, she might be a bit scared or unsure, but then she would start to see the advantages of his dragon form and work with him. For example, she could use his ability to fly to reach places faster.
They might start with some mutual suspicion. Percy would be cautious around Thor as he's a very powerful being from a different mythology. Thor might see Percy as a bit of an oddity at first. But then they could start to exchange stories about their adventures. Percy could tell Thor about his battles with the Titans, and Thor could share his tales of fighting giants. This would lead to a newfound respect between them.
The other Asgardians like Heimdall could also be present. Heimdall, with his all - seeing eyes, might be observing the human who has the hammer. He could play a role in guiding the human on how to use the power of the hammer properly or warn them of impending threats from Asgardian enemies.
