If May joins Team Galactic in the fanfic, her character would go through significant changes. At the start, she might be curious and excited about being part of something new. But as she realizes the true nature of Team Galactic, she would experience a lot of guilt for being associated with them. This guilt would drive her to try and make amends. She would become more determined and勇敢 (brave in Chinese, for lack of a better English equivalent in this context). Her relationship with her Pokemon would also change, becoming stronger as they support her in her fight against Team Galactic.
Pikachu would likely be very confused and resistant. Pikachu has a strong bond with Ash and knows his true nature. It would probably try to shock Ash out of whatever trance or false belief he has from joining Team Galactic. For example, when Ash starts to follow Team Galactic's orders that go against his usual principles, Pikachu might refuse to cooperate and try to show Ash that he's on the wrong path.
Well, if May joins Team Galactic in the fanfic, she might be used as a pawn at first. Team Galactic could see her as a way to get to other trainers or Pokemon. However, May is a strong - willed character. So she could start to secretly undermine Team Galactic from within. For example, she might feed false information to them or help other Pokemon escape their clutches. Eventually, she would probably lead a rebellion within the team to expose their wrongdoings.
One possibility could be that Ash is initially deceived by Team Galactic's false promises of creating a better world for Pokemon. He might be drawn in by their grand talk about power and a new order. For example, they could convince him that their plans for using the power of the legendary Pokemon would benefit all Pokemon in the long run. However, as he spends more time with them, he starts to notice their more sinister motives, like their disregard for the balance of nature and the harm they are actually causing to Pokemon habitats.
One possibility is that Ash joins Team Galactic under some sort of misunderstanding. Maybe he thinks they are a group with good intentions at first. Once he realizes their true nature, he has to figure out a way to escape or stop them. This could create a lot of tension and action - packed scenes in the fanfiction.
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.
Ash joining Team Galactic in fanfiction could mean a complete shift in his character arc. He might be forced to do things against his will at first. But as time goes on, he could use his knowledge of Pokemon to gain an upper hand within the team. For example, he could use his bond with his Pokemon to resist the team's orders that are harmful to Pokemon.
Obviously, Team Galactic itself would be the main antagonists. Their leaders, like Cyrus, would play a big role. Cyrus has his own extreme ideas about remaking the world, which goes against the harmony of the Pokemon world. He would see Dawn as a tool to achieve his goals, and his cold and calculating nature would make him a formidable foe for Dawn in the fanfiction.
Kagome's character development could involve her learning about the responsibilities that come with being a Legendary Pokemon. In the fanfic, she might initially use her powers for her own benefit or to get back to her normal form. But as she meets other Pokemon and trainers who are in need, she starts to understand that she has a duty to protect the Pokemon world. This realization could transform her from a somewhat self - centered girl (in the sense of just wanting to go back to normal) to a selfless hero in the Pokemon world.
Her character could develop a darker side. Being around the Akatsuki, who are often associated with more morally ambiguous actions, might make her question her previous beliefs. She could become more ruthless in combat and decision - making.
Naruto's personality might become more reserved initially. The Anbu experience often makes ninjas keep their emotions in check. So, he might not be as boisterous as the original Naruto. For Sasuke, he could be more on edge around Naruto. He would sense the change in Naruto and feel pressured to keep up. Sakura might become more cautious too. She would see the more serious side of Naruto and might try to be more like him in terms of being focused during missions.
