His sense of adventure could skyrocket. Being a dragon gives him the ability to explore in ways he couldn't before. He might be more willing to take risks and venture into unknown territories, both in the magical world and perhaps even into parts of the human world that are off - limits to normal humans. And this newfound boldness could also change how he interacts with the gods and other powerful beings.
On the other hand, he could also become more protective. Dragons are often seen as guardians in mythology. So, Percy might feel an even stronger urge to protect his friends and Camp Half - Blood. He would use his new form to keep them safe from any threats, whether it's a horde of monsters or some other danger.
He might become more fierce. As a dragon, he has the physical power to match his temper at times. He could be less patient with those who oppose him.
His personality would likely become more protective. Since Cerberus is a guardian, Percy might feel an intense need to protect those around him more than ever.
Well, his confidence might shift. As a woman, Percy could be more cautious at first, having to deal with different social expectations. But he could also become more empathetic. Since society often expects women to be more in tune with emotions, Percy might start to pick up on the feelings of others more easily.
She might become more assertive. As a dragon, she has more physical power, and this could give her the confidence to be more outspoken. But she would still keep her kind heart. So, instead of being a shy bystander, she could be more proactive in helping others.
He might become more aggressive due to the dragon's natural instincts. Dragons are often seen as fierce creatures, so he could be quicker to anger.
His relationship with Annabeth would be really different. She would have to adjust to this new form of Percy. At first, she might be a bit scared or unsure, but then she would start to see the advantages of his dragon form and work with him. For example, she could use his ability to fly to reach places faster.
His confidence might increase. Aphrodite is all about charm and allure, and being around her could rub off on Percy. He might become more self - assured in social situations, which is quite different from his sometimes - awkward self in the original stories.
His personality might become more refined. As a goddess, Percy could be more composed and less impulsive. He'd have to think more like a divine being, which might make him more calculating in his actions.
He becomes colder. His emotions like empathy and kindness are gone, so he's more likely to act on pure self - interest.
If Ash were to turn into a Pokemon in a fanfic, his personality would surely be affected. He's used to being in control as a trainer, but as a Pokemon, he'd have to learn to follow others' commands or work within a group. His once outgoing and friendly nature might become more cautious. He'd have to be more aware of predators and threats. And his competitive spirit might take on a different form. Instead of competing in trainer battles, he'd be competing in Pokemon - on - Pokemon battles, which could make him more aggressive or strategic depending on the Pokemon he turns into.
His relationship with Annabeth would be different. She might have to get used to Percy being a pegasus. There could be some initial awkwardness, but also a deeper understanding as she sees him in a new form.
