Writers love to mash up different universes and characters. This particular concept could bring in elements of Loki's mischievous nature into Harry's character, creating a whole new set of adventures and challenges for him in the Hogwarts setting.

There are many authors on Wattpad who write about different Harry Potter scenarios, including reincarnation.

One common theme is power and how the reincarnated Harry uses his new - found knowledge to gain more power or use it differently. Another is relationships, like how he interacts with his friends and enemies in a new way.
I really like 'A New Beginning for Harry Potter'. In this fanfic, the reincarnated Harry has a different perspective on his role in the wizarding world. The story dives deep into his relationships with the other characters like Hermione and Ron, and how he tries to prevent some of the tragedies that happen in the original series. It's a great read for any Potter fan.
One interesting story could be where Harry is reincarnated as a pure - blood in a different era. He uses his past knowledge to change the wizarding world for the better, like reforming the Ministry of Magic's corrupt practices. Another might have him reincarnated as a Muggle - born and facing the same prejudices he once fought against, but from a new perspective. There could also be a story where he's reincarnated as a magical creature, perhaps a phoenix, and has to navigate the wizarding world in a completely different form.
One great reincarnation fanfic is 'The Second Son'. It has an interesting take on Harry being reborn with his memories intact. The author does a wonderful job of exploring how Harry's prior knowledge changes his new life at Hogwarts and his relationships with other characters.
Another feature is the change in relationships. Since Harry has a different perspective due to his reincarnation, his relationships with Ron, Hermione, and the teachers can be drastically different. In some fics, he may be more cautious or more assertive in these relationships. Also, the plot can take new directions. For instance, if Harry is reincarnated with new magical abilities, it can lead to completely different story arcs that involve exploring these powers and how they affect the wizarding world.
The protagonist who is reincarnated as Harry Potter is obviously very popular. Readers are interested in how they navigate the world with their new - but also familiar - identity. Hermione Granger is also popular as she often has interesting interactions with the reincarnated character. Her intelligence and strong - willed nature make her a great character to include in these fanfics.
One possible plot could be that Harry starts to show Loki - like traits early on at Hogwarts. He might use his trickery to outwit his enemies, like the Malfoys. Maybe he even uses some of Loki's shape - shifting abilities in a magical way to get out of tricky situations during his adventures.
One possibility could be through some sort of magical accident. Maybe a powerful dark magic spell gone wrong in the Harry Potter world that somehow reaches across dimensions and pulls Batman's soul into the HP universe. Another way could be through the will of a powerful magical being. For example, a wizard or witch with god - like powers decides to reincarnate Batman for their own purposes, perhaps to bring a different kind of justice to the wizarding world.
