Well, he might bring his magical skills and experiences into the Vrasta fanfiction world. Maybe he'd use his spells to solve some of the unique problems there, or make new friends among the Vrasta characters. It could also be that his presence changes the power dynamics in that fictional setting.
In the Vrasta fanfiction, if Harry Potter were to join, it would create a whole new set of storylines. His identity as the Boy Who Lived would attract a lot of attention. Some characters in the Vrasta world might be in awe of his abilities, while others could be jealous or see him as a threat. His knowledge of the wizarding world, from potions to dueling, could be shared or even adapted in the Vrasta fanfiction. And depending on the nature of the Vrasta world, he might have to face new villains or challenges that are different from those in the Harry Potter series. This would not only change his own character arc but also the overall plot of the Vrasta fanfiction.
He could introduce new strategies based on his experiences at Hogwarts. Since he's faced so many challenges there, he'd be able to think of unique ways to win matches. Also, his fame might attract more fans to the Vrasta Vultures. He could be like a star player who not only plays well but also brings a lot of attention to the team.
In a fanfiction where Harry Potter joins a gang, it could lead to a whole new set of adventures. The gang might be involved in some underground wizarding activities, like illegal potion - making or trading in dark artifacts. Harry, being part of it, would be caught in a web of danger. He would have to navigate between his new 'friends' in the gang and his old friends from Hogwarts. This could create a great internal conflict within him as he tries to figure out who he really wants to be and what kind of wizard he wants to grow into.
In this fanfiction, Harry might also form alliances within the Wizengamot. He could team up with some of the more progressive members to counter the conservative forces. His skills as a wizard and his leadership qualities from his time at Hogwarts could come in handy in the political arena of the Wizengamot. He could even start initiatives to improve the relations between the wizarding world and other magical creatures, which would be a significant step forward in the world of Harry Potter fanfiction.
He might use his magic to create amazing stage effects. For example, he could make the instruments float while playing, which would surely draw a huge crowd.
Well, he might bring his unique magical skills from the wizarding world of Hogwarts. His ability to use spells like Expecto Patronum could be a great asset against the darkspawn that the Grey Wardens fight. Maybe he'd form new friendships with the Wardens and learn their ways of combat and survival.
In a Harry Potter fanfiction where Bellatrix Lestrange joins, she could be a major source of conflict. She's extremely skilled in the Dark Arts. Her addition to the story might see her influencing the plot in ways that are both unpredictable and dangerous. For instance, she could manipulate other characters, especially those on the darker side of the wizarding world. She might also introduce new magical elements or artifacts that are related to the Dark Arts. Her character is so complex and unpredictable that she could either be a pure antagonist or, in a more creative take, have a change of heart and become an anti - hero, but this would require a very well - written and thought - out plot.
Well, he could bring his unique magic skills. Maybe he'd use spells to enhance the Avengers' abilities or help them in tricky situations. For example, he could use a spell to make Iron Man's suit even more powerful or create illusions to deceive the enemies like Loki does.
Well, he might learn a whole new set of combat skills. The Varia are known for their tough and unique fighting styles. Harry could become even more formidable in battle. Maybe he'd also have to adapt to their strict code of conduct, which would be a big change from Hogwarts.
Well, he'd probably bring his magical skills to the military. Maybe he could use spells for things like reconnaissance. For example, he could use the invisibility cloak to spy on the enemy, or use the Patronus charm to send messages in a secure way. His quick thinking and combat experience from fighting Voldemort would also be useful in military strategies.
If Harry Potter were to join Magneto in fanfiction, it would be an interesting blend of two different fictional universes. Harry's loyalty and courage could potentially influence Magneto. Maybe Harry would try to convince Magneto to use his powers in a more benevolent way. On the other hand, Magneto's experience in fighting for the rights of the oppressed could give Harry new perspectives on the treatment of Muggle - borns in the wizarding world. Their combined forces would surely be a threat to any foe, with Harry's spells and Magneto's control over metal.
