Y/N should have their own goals and dreams. If they're interested in becoming an Auror, that can shape their actions and decisions. Their reactions to Draco should be based on their personality. If they're a shy person, they might be more hesitant around him. And make sure their dialogue is natural. Don't make them say things that are out of character just to move the plot along. For instance, if Y/N is a studious type, they're more likely to talk about books or spells when interacting with Draco.
The Phantom Troupe could form an uneasy alliance with some of the more morally grey members of the Justice League, like Catwoman or Lobo. They might team up to take down a common enemy that the League can't deal with using their usual methods because of legal or moral constraints.
For Gon, his relationship with Chrollo would be crucial. Chrollo is the leader of the Phantom Troupe, and Gon's sense of justice might clash with Chrollo's leadership. However, Gon might also see some good in Chrollo and try to influence him in a positive way. Killua would likely form alliances with the more practical members of the troupe, like Pakunoda. She's smart and has a good understanding of the group's dynamics. Killua could learn a lot from her about how to survive within the troupe. As time passes, both Gon and Killua would have to adapt to the different personalities and values of the Phantom Troupe members, which would be a continuous process of give - and - take.
One possible fanfiction could involve the Phantom Troupe's unique abilities clashing with the superpowers of the Justice League members. For example, Chrollo's nen ability to steal other's abilities might be a huge threat to the League. Maybe he targets Superman and tries to steal his super strength. This could lead to an epic battle where the League has to figure out how to counter the Troupe's devious tactics.
One possible plot could be that Killua joins the Phantom Troupe in order to protect Gon. He might think that by infiltrating the troupe, he can keep Gon safe from their potential threats. Maybe he initially pretends to be on their side, but as time goes on, he starts to question his own actions and the morality of the troupe.
I like the idea of a Danny Phantom and Ben 10 crossover. Ben has the Omnitrix which gives him access to different alien forms, and Danny has his ghost powers. They could either be rivals at first, each thinking their powers are better, or they could quickly team up to face a threat that requires both their unique abilities. It would be a fun clash of two very different power - based universes.
I think Danny Phantom crossover fanfictions can be really exciting. They bring together different universes and characters, creating unique and unexpected storylines. For example, a crossover with a superhero universe could lead to Danny teaming up with other heroes to fight a common enemy. It's a great way to explore new character dynamics and expand the Danny Phantom world.
It could also be related to the internal politics within the entertainment industry in the fanfiction. There might be some higher - ups who don't like Y/N's presence around BTS and Stray Kids. So, they arrange some difficult situations for Y/N which end up in Y/N getting hurt. For instance, they might give Y/N impossible tasks to perform and when Y/N fails, there are severe consequences that lead to their harm.
