When Ash is tied up in fanfiction, it usually creates a sense of urgency and danger. It forces other characters, like his Pokémon or his friends, to step up and take action. For example, his Pokémon might have to work together in a different way than usual to rescue him. This can lead to new character developments and relationships.
The theme of Ash being tied up can completely change the direction of the plot. It can introduce new villains or motives. For instance, if a previously unknown group ties him up, it could be because they have a different view on Pokémon training. This then leads to a debate or conflict within the story about the right way to train Pokémon. Also, it can make Ash more vulnerable, which is a contrast to his usually confident self in the official Pokémon series, and this vulnerability can be used to explore his character deeper.
The overprotection in the fanfiction can add a lot of drama to the plot. There could be conflicts between Ash and his overprotective friends. He might feel suffocated and try to break free, which can lead to arguments. On the other hand, it can also lead to some heartwarming moments. When Ash does get into a tough situation despite the overprotection, his friends coming to his rescue can strengthen their bonds and move the story in an emotional direction.
Ash's injury can change the whole dynamic. If he's injured, he can't lead his Pokemon in battles as effectively. So, his friends might have to take over. For example, Brock could use his knowledge of Pokemon care to help heal Ash and also strategize for battles in Ash's absence.
One possible plot could be that Ash gets tied up by a group of Team Rocket grunts who manage to outwit him. They tie him up to stop him from interfering with their latest evil plan to steal rare Pokémon. His Pokémon then have to work together to free him and foil the villains' scheme.
Team Rocket is the most likely candidate. They've always been after Ash's Pikachu and tying him up would be a way to stop him from protecting his Pokémon. They could use ropes or some kind of Pokémon - powered restraining device.
In some Pokémon Ash tied up fanfictions, the situation is more of a misunderstanding. Maybe a group of new trainers thought Ash was a poacher because he was in an area that was restricted for a special Pokémon breeding ground. So they tied him up. Ash then has to explain his situation and his love for Pokémon to them. This type of fanfiction often delves into Ash's character, showing his passion for Pokémon and how he can turn a bad situation into a good one by making new friends among the trainers who initially mistook him.
The reunion of Ash in fanfiction can be a catalyst for many things. If he reunites with a character who has some hidden knowledge or power, it can open up new story arcs. For instance, if he meets an old sage who tells him about a secret Pokémon technique. Also, when he reunites with a Pokémon he thought was lost forever, it can bring back memories and emotions that were buried. This can lead to Ash making different decisions in the story, like choosing a different path in his journey or changing his training methods.
It could also expand the lore. Old fanfics often have their own interpretations of the Pokemon world. When Ash uses ideas from them, it might introduce new concepts or relationships that weren't part of the original story. This can make the Pokemon world seem even larger and more complex.
Ash's transformation into a Gardevoir would have a complex impact on his relationships. Some Pokemon that were once his rivals might see him in a new light and either be more respectful or more envious. His bond with his own Pokemon team would change too. They would have to adapt to his new abilities and appearance. And he would form new relationships with Pokemon that are more associated with Gardevoir's kind, like other Psychic or Fairy - type Pokemon.
It can bring new discussions to the fan community. People will debate about the possible reasons for Serena hating Ash. This can lead to more creativity as fans explore different scenarios and character developments. However, it might also put off some fans who are only interested in positive portrayals of the characters.
The argument might also make their relationship more complex. Other characters in the Pokemon world might get involved, either trying to mediate or taking sides. This could create a web of relationships around Ash and Serena, affecting how they interact not only with each other but also with their friends and Pokemon. And depending on how they handle this situation, their relationship could either grow stronger or become more distant.
