Raven would have to adapt to a life full of social events and expectations. She might find it difficult to fake enthusiasm for things like royal balls and diplomatic meetings. But she could use her intelligence to quickly learn the politics and social norms. Apple, in Raven's world, would have to adapt to a more individualistic culture. She would need to learn to make decisions for herself rather than relying on the guidance of a court. Over time, she could become more independent and start to influence the people around her with her own ideas of fairness and justice.
A plot could revolve around the idea that a prophecy was tied to their true births. In Raven's world, there was a prophecy that a princess born on a certain day (which was actually Apple's real birth) would bring great change. In Apple's world, a similar prophecy about a powerful magic - user (Raven's true self) existed. When they are switched at birth, the events start to unfold in unexpected ways. The two girls must then figure out how to fulfill the prophecies in the wrong worlds they were raised in, all while dealing with the challenges of their newfound identities.
The development would be quite complex. Naruto, taking on Sasuke's life, would be more in tune with the darker side of the ninja world. He might struggle with the coldness that Sasuke often showed but also use his own warmth to thaw some of the Uchiha's colder relationships. Sasuke in Naruto's position would have to adapt to Naruto's simple yet powerful dreams. He could use his Uchiha abilities to make Naruto's dream of becoming Hokage more achievable in a different way. Also, their battles against common enemies would be very different as they would approach them from each other's perspectives.
Daenerys Targaryen would likely see the new land as an opportunity to expand her rule. She would approach it with her leadership skills and her dragons. However, she would also have to be careful as the new land may have its own powerful forces. She might start by trying to make alliances with the local tribes or kingdoms, much like she did in Essos, but she would soon realize that the new land has its own unique challenges that require a different approach.
Well, in a fanfiction where they switch lives, Naruto would suddenly find himself in Sasuke's world of revenge. He might use his own positive attitude to try and change Sasuke's path from the inside. On the other hand, Sasuke in Naruto's place could bring a more serious and focused approach to Naruto's goals. He might train differently or interact with Iruka and Kakashi in a new way that could lead to some unexpected character developments for everyone involved.
Bay's family might have a mixed reaction. Daphne could be initially jealous as Bay is getting so much attention due to the pregnancy. Regina would probably be very supportive, offering her own experiences as a mother. Kathryn might be more concerned about the practical aspects like Bay's future and education. As for Ty's family, if they are in the military - minded family, they might be disappointed at first as it could disrupt Ty's military career, but eventually come around to support them.
Naruto is used to a world full of ninjas and chakra. In Superman's hometown, which is so different, he'd have to start from scratch in some ways. He'd need to learn about the local laws and customs. His strong willpower would be key. He might start by helping people in small ways, using his ninja abilities in a more discreet way. For example, he could use his speed to stop small crimes before they escalate. As he gets more involved in the community, he'd gradually adapt and become part of the town.
The charm of 'Switched at Birth' OC fanfiction also lies in the exploration of different identities. Just like the main theme of the show which deals with the identity issues of the switched - at - birth characters, an OC can have their own identity struggles. This could be related to their cultural background, personal beliefs, or social status, and how they navigate through the world of the show.
Set the scene well. Describe the places where the story takes place. If it's in a hospital when she finds out about the switch, describe the sterile environment, the sounds, and the people around. And when it comes to her pregnancy, describe how she's changing physically and how that affects her daily life.
Sasuke would likely be very cautious at first. He'd be observing everything closely, trying to figure out the rules of this strange place. His Sharingan might give him an advantage in seeing through some of the illusions in Wonderland. Naruto, on the other hand, would probably be more excited and jump right into things, ready to make friends with the odd - looking creatures.
Tony Stark would adapt by using his intellect. He'd quickly analyze the magic system and try to find ways to work with it. For example, he might figure out how to make his suit interact with magical fields. Thor, being from a world of magic - like powers already, would adapt fairly easily. He'd see Hogwarts as a new and interesting place to explore his powers further. Captain America would rely on his discipline and ability to learn quickly. He'd study the rules and customs of Hogwarts and follow them as best he can.
