The boy's life would be turned upside down. He'd no longer be able to go to school or interact with his human friends in the same way. He'd have to learn the language and customs of the Pokemon world. His senses would be heightened, allowing him to see in the dark better and hear faint sounds. He might also develop a natural instinct to protect those he cares about, which could lead him into dangerous situations as he tries to defend his new Pokemon friends from threats.
His life would change a great deal. For one, he'd have to get used to moving on four legs instead of two. He'd also have to learn how to use his new Umbreon abilities like Quick Attack and Foul Play. Socially, he might be shunned by some humans who are afraid of Pokemon, but be welcomed by other Pokemon who see him as one of their own.
Sakura's personality could become more competitive. In the ninja world, male characters are often shown to be more competitive. So, as a boy, she might be eager to prove herself against other male ninjas. She could also develop a more laid - back attitude in some aspects, like not being as self - conscious about her appearance as she was when she was a girl.
He'd probably be more innocent. The snobbish and often cruel Draco we know would be replaced with a more naive and curious version. He might not have the same prejudices as he does as a teen or adult.
His relationship with Tails would be strained. Tails would be confused and a bit scared at first. Sonic would have to hide his new vampiric urges from Tails, which would create distance between them. With Knuckles, there might be more of a distrust as Knuckles is very protective of their world. Knuckles might see Sonic as a threat now that he's a vampire.
With his love interests, if he had any, it would be completely different. If he was interested in a girl before, she might see him as a rival now. And if there were guys who had a crush on him as Superboy, they might be confused or even more attracted to him as a girl. Also, his relationship with his family members, like his father figure, might change as they adjust to his new gender.
In a fanfiction where Natsu turns into a girl, his relationships would be turned upside down. His relationship with his friends would be filled with awkward yet endearing moments. His male friends might have a hard time adjusting at first, but gradually they would accept the new Natsu. Natsu's relationship with the female characters would also change. He might find himself being included in more girl - only activities, which would strengthen his bonds with the female members of the guild. And his relationship with the outside world, like with other guilds or villains, would also be different. Enemies might underestimate him because he is now a girl, but Natsu would prove them wrong with his strength and determination.
If Naruto was turned into a monster in fanfiction, his relationship with the village would change drastically. The villagers who have finally started to accept him as a hero would once again be fearful. His friends would be divided in their reactions. Some, like Shikamaru, would immediately start thinking of ways to solve the problem. Naruto's relationship with his mentor, Kakashi, would be put to the test. Kakashi would have to balance his duty to the village and his loyalty to Naruto. And Naruto himself would feel isolated, which could further impact his relationships as he might become more withdrawn in his monster form.
Naruto's life would change drastically. He would have to adapt his living space to accommodate the baby. His daily routine would include things like feeding, changing diapers, and putting the baby to sleep. Also, he would be more cautious in battles because he now has someone depending on him at home.
If Trunks turned into a girl in fanfiction, his personality might become more in tune with feminine traits. He could become more empathetic. For example, he might be more attuned to the emotions of others around him. Also, his fighting style could potentially change. Maybe he would rely more on agility and finesse rather than brute strength. His relationships with other characters would also shift. His male friends might start to see him in a different light, and he might attract new friends who are female.
Ash's personality could become more diplomatic as a girl. In the Pokémon world, he would need to navigate different social situations. As a girl, he might use charm and persuasion more often. His love for Pokémon would still be there, but he could show it in a more gentle way. For example, instead of just being excited about catching new Pokémon, he might focus more on the well - being and happiness of the Pokémon he already has.
If turned into a kid, Deadpool's personality would lose some of its edge. He'd be more impulsive in a child - like way, not thinking about the consequences as much as he does as an adult. His love for chaos would remain, but it would be more like a child's playfulness. He might also be more vulnerable in a sense, showing emotions more openly like a kid does.
