In this fanfiction, Harry might face intense training sessions. He could struggle at first to keep up with the more experienced players on the team. Maybe he'll have a rival on the team who doubts his abilities but he'll prove them wrong with his natural talent.
Well, the story might start with Harry getting an unexpected invitation to join a professional Quidditch team. He has to quickly adapt to the more competitive and cut - throat environment. His old Hogwarts friends might be jealous or proud. As he progresses in the team, he could be involved in a big tournament where the fate of the team depends on his performance.
Ron and Hermione could still be important characters. Ron might be super excited for Harry and offer some support and advice. Hermione could be the one making sure Harry doesn't neglect his studies while being on the team.
It could be a jealous teammate who feels that Harry is getting all the attention and glory. This teammate might try to sabotage Harry during practices or matches.
Obviously, Harry Potter himself is a very popular character. He is often the central figure in these fanfictions, as he is the star Seeker of the Gryffindor team. His skills and leadership on the Quidditch pitch are usually highlighted.
Harry might feel really sad at first. He loves Quidditch and being shunned by the team would be like a rejection of something he's passionate about. He could start to isolate himself even more, spending time alone thinking about what he did wrong.
One interesting plot could be Harry leading the Quidditch team to victory against a seemingly unbeatable rival through a new and innovative strategy he devises. Maybe he discovers a secret about the Quidditch pitch that gives his team an edge.
One great fanfiction is 'The Gryffindor Quidditch Revolution'. It focuses on a new player who brings innovative strategies to the team. The story is full of action - the intense Quidditch matches are described vividly, making you feel like you're right there in the stands. The characters are well - developed, and it stays true to the spirit of the Gryffindor team in the original books.
One possible reason could be jealousy. Maybe Harry has some extraordinary talent that makes the other team members feel threatened. For example, if he's a much better flyer or has a special ability related to the game that they don't. Another reason might be some false rumors spread about him. If someone starts a rumor that Harry is using unfair means to win, like a made - up magic charm, the team might shun him out of a sense of fairness in the game.
Perhaps in the fanfiction, the Quidditch team gets influenced by a dark wizard who has a grudge against Harry. The wizard uses a spell to make the team members believe Harry is a threat to them. So they start to betray him by not passing the Quaffle to him during the game, or even colliding with him on purpose during a fly - around. This would lead to Harry feeling extremely isolated and confused as he thought his team was like family.
