How could Izuku's character develop in a fanfiction where he grows a fox tail?

In this fanfiction, Izuku's character development could be quite complex. Initially, he would struggle with the physical changes, like learning how to control his tail movement and deal with the extra sensitivity of his new ears. Emotionally, he would face a lot of inner turmoil. But as he starts to explore the potential of his new form, he could become more confident. He might also develop new relationships with characters who are attracted to his unique form, which could further shape his character into someone who is more open - minded and less shy than he was before.

Izuku's character would develop in several ways. Firstly, he'd learn to rely on magic rather than just his physical strength and quirk. This would change his combat style. Also, the social aspect of Fairy Tail would make him more outgoing. He'd interact with a diverse group of wizards, which would expand his world view and make him more adaptable. He might start to see the value in having fun and not always being so serious about training and fighting, like the Fairy Tail members do.

Well, perhaps the plot could involve Izuku suddenly growing ears and a tail due to some sort of experiment gone wrong. He then has to deal with the new appendages while trying to keep it a secret from his friends and teachers at U.A. High. Maybe he discovers new abilities that come with these changes, like enhanced senses.

If Shirou joins Fairy Tail in fanfiction, his character might develop a greater sense of belonging. He has always been on his own journey, but in the guild, he'd be part of a team. This could lead to him being more open about his feelings and past experiences. Also, his combat skills could evolve as he trains with the other members and is exposed to new fighting styles and magical techniques. He might even start to develop his own form of magic - influenced combat, which would be a new and interesting aspect of his character growth.

One possible plot could be that Naruto discovers a new jutsu or is under a curse that causes him to grow fox ears and a tail. This new form might make his friends initially confused or even a bit scared. But as the story progresses, he learns to control this new part of himself and uses it to his advantage in battles, like having enhanced senses from the ears and better balance with the tail.

Well, initially, Izuku might be overwhelmed by his new cosmic quirk. But as he trains, he becomes more confident. For example, he could start by accidentally causing small cosmic disruptions and then learn to control them precisely.

Harry might become more refined. Fleur has a certain elegance about her, and growing up with her could rub off on Harry. He could become more polite and cultured in his ways.

His character may become more self - reliant. Since he has to fend for himself in the forest, he learns to trust his own instincts. For instance, when facing a wild animal, he has to quickly decide whether to fight, flee or try to communicate with it.

One possible reason could be a strange side - effect of his connection with the Nine - Tails. Since he has the Nine - Tails' chakra within him, in the fanfiction world, this chakra might start to physically manifest in the form of fox ears and a tail during his time in Wave. Maybe the unique environment or a specific event in Wave triggered this abnormal transformation.

Well, perhaps it could be part of a transformation arc in the fanfiction. Izuku starts growing the fox tail gradually, and it's related to an ancient power or a prophecy. As the tail grows, he attracts the attention of certain characters who either want to help him or use him for their own gain. He might have to go on a journey to find out the origin of this new feature.
