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.
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.
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.
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.
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.
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.
In a 'naruto joins team hebi fanfiction', perhaps Naruto joins them because he realizes that the line between good and bad isn't as clear as he thought. Team Hebi might be on a path that Naruto initially opposes, but as he gets to know them, he discovers they have some valid reasons for their actions. He could then try to influence them to change their more dangerous or unethical ways.
In this fanfiction, Naruto could join Team Taka as a result of a political situation. For example, the villages might want to form a temporary alliance through the ninja teams. Naruto's presence would bring his unique skills and also his sense of loyalty and friendship. He might teach the members of Team Taka about the value of comradeship which they lack to some extent.
The plot might involve a power struggle within Team Rocket. Ash and Misty could be brought in because they possess certain skills or knowledge. For example, Ash's bond with his Pokémon could be seen as a valuable asset. Misty's understanding of water - type Pokémon might also be desired. However, they soon realize that they are being used in a power play between different factions of Team Rocket, and they must decide which side to take or find a way to break free from the whole mess.
In a 'pokemon dawn joins team galactic' fanfiction, the plot could involve Dawn being lured by Team Galactic's false promises of power. Maybe they convince her that their goals for the Pokemon world are noble at first. She might start to question her own values and the way she has been training Pokemon. However, as she delves deeper into Team Galactic, she could discover their true evil intentions and then have to struggle to break free and redeem herself.
Well, one plot twist could be that Ash is actually a double agent. He pretends to join Team Rocket to gather information for the good guys. Maybe he discovers a big secret plan of Team Rocket, like they're planning to steal all the Pokeballs in a certain region. This would completely change the power dynamic and put Team Rocket on high alert.
