If Harry Potter were to become an Avenger in fanfiction, it would be a very interesting mix. Harry is used to fighting dark wizards in the wizarding world. But the Avengers face different kinds of threats. He would have to learn to work with technology - something he's not really familiar with. For example, he might be confused by Iron Man's high - tech suits at first. However, his ability to think on his feet and his courage would make him a valuable addition to the team. He could also introduce the Avengers to magic, which could open up new ways of fighting for them.
In a fanfiction where Harry Potter becomes an Avenger, it would create a whole new dynamic. Harry has a strong sense of justice which aligns well with the Avengers. His Patronus charm could be used in various ways, perhaps as a form of protection for the team or to send messages. And his knowledge of potions might lead to some interesting developments. He could create potions to enhance the Avengers' abilities or to heal them more quickly. Plus, his experience with the Dementors could give him an edge in dealing with foes that have a draining or fear - inducing effect.
Well, he'd probably bring his magic skills to the Avengers. He could use spells like Expelliarmus to disarm villains quickly. His broomstick flying skills might also come in handy for getting around in a hurry or for some unique battle maneuvers.
If Loki becomes an Avenger in fanfiction, it would be a wild ride. He'd bring his complex personality to the team. His relationship with Thor would also be an interesting aspect. They could have brotherly moments within the team dynamic. Loki might also start to develop real friendships with the other Avengers, which would be a big change for him.
In some fanfictions, if Harry Potter becomes a warlock, he might gain even more powerful magic. He could have greater control over spells and be able to perform magic that was previously thought impossible. For example, he might be able to manipulate time in a more complex way or have the power to instantly transport himself anywhere in the wizarding world without the need for a Portkey or Apparition.
If Harry Potter becomes god in fanfiction, he might completely reshape the magical world. He could rewrite the laws of magic, perhaps making it more accessible and less dangerous. He could also bestow extraordinary gifts upon his friends. Hermione might gain the ability to instantly understand and master any spell or bit of knowledge, and Ron could become an unbeatable warrior with superhuman strength in the face of any danger.
In this kind of fanfiction, Harry might teach his children magic in a very different way from how he was taught. He would be extremely protective, having faced so many dangers himself. Maybe he'd pass on the lessons he learned from his own battles, like the importance of friendship and courage.
If Harry Potter becomes the Joker in fanfiction, he would probably start to question all the values he once held. The Joker is all about subverting order, so Harry might begin to undermine the Ministry of Magic and other institutions. He could use his knowledge of magic to play cruel pranks on people, not the innocent kind of pranks he used to do. His Gryffindor courage could be twisted into a reckless disregard for the safety of others.
If Harry Potter becomes a Lamia in fanfiction, his relationships would change drastically. His friends might be both intrigued and a bit scared at first. He would have to adapt to his new form and its characteristics. For example, he may need to learn how to control any new instincts that come with being a Lamia. Also, his role in the fight against Voldemort could be completely different. Instead of using a wand in the traditional way, he could use his Lamia - related powers to combat the dark forces.
If Harry Potter becomes a demon in fanfiction, his relationships would be severely affected. His friends like Ron and Hermione would be very confused and possibly afraid of him. They might try to find a way to reverse the transformation. And Hogwarts itself would be in chaos. The teachers would be divided on how to deal with him, some might want to help him while others might see him as a threat to the safety of the school.
Well, it would be a total chaos. He might use his magic skills to cause destruction. For example, he could turn Hogwarts into a dark fortress and rule over it with an iron fist. His friends would be shocked and probably try to stop him, leading to some really intense battles.
In such a fanfiction, Harry might gain enhanced physical abilities like super strength and speed. He could also have new magical powers related to his vampiric nature. For example, he might be able to hypnotize his enemies. His relationships with his friends would be severely tested. Hermione might try to find a way to reverse his vampirism while Ron could be initially afraid of him.
In this kind of fanfiction, Harry could potentially use the Hulk's strength to fight Voldemort in a very different way. He might be able to smash through dark magic barriers with ease, and his rage - like the Hulk's - could be a new source of power against the Death Eaters.
