One idea could be swapping the personalities of Deku and Bakugo. Deku could be bold and brash, while Bakugo might become more timid and self - doubting. It would create a whole new dynamic in their relationship and how they interact with other characters.
First, study the original characters thoroughly. Know their traits, backstories, and relationships. Then, when swapping their personalities, think about how their new traits would interact with their existing circumstances. For example, if you swap Midoriya and Bakugo, Midoriya's new aggressive personality would likely have a different impact on his relationship with All Might, who was used to his meek self.
A Bakudeku personality swap fanfic can be really interesting. In such a story, the typically explosive and brash Bakugo might become more reserved and empathetic like Deku usually is. Meanwhile, Deku could take on Bakugo's confident and assertive traits. This swap can lead to unique character interactions. For example, their relationships with other classmates would change drastically. Bakugo, in Deku's body, might struggle with his newfound lack of physical strength at first but would likely use his strategic mind to compensate. And Deku in Bakugo's body could have to deal with the high expectations and the fear others have of Bakugo's power.
One popular trope is the 'fish out of water' experience. Bakugo, now with Deku's personality, has to adjust to being less physically capable but more emotionally intelligent. He might struggle to fit in with his former self's friends. Another trope is the newfound respect between the two. As they experience each other's lives, they gain a deeper understanding of one another. Also, the 'role - reversal' in hero training is common. Deku, in Bakugo's body, might show a different fighting style that combines Bakugo's power with Deku's strategic thinking.
One common theme is identity exploration. When the characters swap bodies, they have to re - evaluate who they are and how they are perceived. Another theme is relationship dynamics. Their relationships with friends, family, and love interests change as they are in a different body. For example, a male character in a female body may experience different levels of closeness or distance from their friends.
There's also 'Gender - Bent in BNHA'. This fanfic takes a different approach where the body swap is more of a long - term situation. It shows how the characters grow and change as they navigate life in the opposite gender's body. It has a great plot that keeps you hooked from start to finish, and the character development is really well - done.
One common theme is the exploration of different relationships. When personalities are swapped, characters interact in new ways. For example, Naruto with a different personality might have a different dynamic with Sakura or Kakashi.
One idea could be to swap Ruby and Weiss's personalities. Ruby, with Weiss's more uptight and rule - following nature, would be strict about combat training and protocol. Meanwhile, Weiss, with Ruby's carefree and enthusiastic personality, would be more likely to charge into situations without over - thinking. This would create a lot of humorous and interesting character interactions.
One idea could be to swap the personalities of Twilight Sparkle and Pinkie Pie. Twilight could become super bubbly and party - loving, while Pinkie Pie could turn into a studious and serious pony. It would lead to hilarious situations as they try to adapt to their new personalities within their daily lives in Ponyville.
Well, 'The Great Personality Swap in Naruto-verse' is a great read. In this fanfic, not only the main characters like Naruto have their personalities swapped, but also some of the side characters. It creates a whole new dynamic in the story. There's also 'Naruto's Altered Ego' which focuses mainly on how Naruto's swapped personality affects his relationships with others, like his friends in Team 7.
