The character could be reborn as a Legendary Pokemon in a world where Legendary Pokemon are hunted. This would make their survival and journey to discover their new identity extremely challenging. They would have to constantly hide their true form while also trying to figure out how to use their powers and find their place in this new and dangerous world.
Well, by changing Kakashi's relationships. For example, the OC might have different interactions with Obito's spirit or with Rin in memories. This can create new emotional depth.
Another way for the main character to stand out is through their knowledge. If they have knowledge from their past life or some other source that gives them an edge in understanding Pokemon behavior, evolution, or hidden locations of items. This knowledge can help them make better decisions, whether it's choosing which Pokemon to catch or where to go next in their journey. They can also use this knowledge to solve problems that other trainers can't.
I think it is. Fanfictions often take existing universes and mix them up in new ways. Harry Potter has its own set of rules regarding magic and the wizarding world, while Pokemon has its own system of catching and evolving creatures. Combining these two means creating a whole new set of adventures. For example, imagine Harry and his friends going on a quest to find a rare and powerful Pokemon in the Forbidden Forest. It could lead to all kinds of new storylines that we haven't seen before.
You can make it unique by changing the setting. For instance, if Ash starts with a Bulbasaur in a post - apocalyptic world where most Pokemon are scarce. This would force him to find new ways to train and care for his Bulbasaur, and also deal with other survivors who might be jealous or desperate for his Pokemon. It would be a completely different dynamic from the original series.
You can make it unique by having the spells be tied to emotions. For example, if a trainer is feeling extremely angry, the transformation spell goes wrong and they turn into a half - pokemon, half - monstrous form. It adds an unexpected twist.
Obviously, Ash is one of the main characters. Since it's about him being a legendary Pokemon in this fanfiction, he's central to the story.
The villains in the fanfiction can also be considered main characters in a sense. They might be after the power of the legendary Pokemon. There could be a team of bad guys who are trying to capture and control a Groudon or a Kyogre to cause chaos in the Pokemon world, and Ash has to stop them. Their actions and plans create the conflict that Ash has to overcome in the story.
One unique aspect could be the exploration of Snape's family history in a different light. The OC might discover something new about the Snape family that changes the way we view his character. Also, the story could deviate from the typical Snape narrative by having the OC - as Snape - use his skills in a completely different field. Instead of just being involved in the war between good and evil, he could focus on magical research or something else entirely.
He can become more confident in his abilities. Since Legendary Pokemon are so powerful, if Ash can form a bond with one and work together successfully, it boosts his self - assurance. In these fanfictions, he might start to believe more in his own intuition and skills as a trainer. For instance, if he manages to communicate with and help a Legendary like Celebi, he'll see himself as someone capable of handling extraordinary situations.
One way to make it unique is to have Ash crossdressing not just for fun or by accident, but as part of a prophecy. There could be an ancient prophecy in the Pokémon world that says a hero will appear crossdressed to save the day. And Dawn could be the one who initially discovers this connection. Also, the story could involve Ash having to master a new type of Pokémon training that is only accessible to those who crossdress, adding a whole new dimension to the plot.
