What are some interesting ideas for 'Harry Potter Justice League fanfiction'?

One idea could be that Harry Potter is magically transported to the DC Universe and is mistaken for a meta - human. The Justice League initially views him with suspicion but then realizes his unique magical abilities could be an asset in fighting a new, magic - based threat.

A really cool crossover concept could be a combined threat that requires both the skills of the Justice League and the magic of the Harry Potter world to defeat. Maybe a powerful alien sorcerer arrives on Earth. The Justice League's superpowers alone aren't enough, so they team up with Harry Potter and his friends. Harry could use the Patronus charm to fend off the dark magic of the alien, while the Flash could use his speed to quickly deliver magic items to different locations as needed.

Another concept is that the magic from the Harry Potter series starts to seep into the DC universe where the Justice League operates. This causes chaos as the laws of physics in the DC world are disrupted. The Justice League has to seek help from Hogwarts professors to understand and contain this new form of magic energy. Superman might be intrigued by the idea of magic being a new power source or a new threat he can't easily overcome with his super strength.

One interesting crossover could be Harry using his magic in the world of the Justice League. For example, he could use spells like 'Accio' to retrieve important items during a Justice League mission. Maybe he'd team up with Superman and use magic to enhance Superman's powers in a unique way.

Imagine a scenario where a young wizard from the Harry Potter world, who has a natural ability to open portals, accidentally opens a gateway to the world of the Justice League. However, this also attracts the attention of Silent Hill. The League and the wizards have to work together to close the portals and keep Silent Hill's nightmares at bay. The wizards can use their spells and the League can use their superpowers to fend off the encroaching darkness.

One idea could be a crossover where the Young Justice team has to team up with the Justice League to face an interdimensional threat. Maybe a powerful villain from another dimension is trying to invade Earth and the combined skills and powers of both groups are needed to stop it.

Maybe a story where some of the younger members of the Young Justice team are frustrated with the Justice League's methods and decide to take on a mission on their own, but end up getting in over their heads and have to call in the League for help. This could lead to a lot of character development and some interesting dynamics between the two groups.

Well, in a dbz justice league fanfiction, there could be a plot where the power levels of the Justice League members are measured using the scouters from DBZ. This could lead to some interesting reactions. Superman might have an off - the - charts power level that astonishes the Z - fighters. At the same time, the Justice League could learn some ki - based techniques from the DBZ characters. For instance, Aquaman could learn how to fly using ki, which would be a huge advantage for him in underwater and above - water battles.

One idea could be Izuku getting accidentally transported to the Justice League's universe. He could then use his unique Quirk to help the Justice League in a battle against a powerful new villain that they're having trouble with. For example, his One For All power could give him the strength to hold back a giant monster while the League figures out a more permanent solution.

Another interesting plot could be that a powerful villain creates a device that can steal powers. He targets both Ben's aliens and the Justice League members. Ben and the League have to find a way to stop the villain before they lose all their powers. They go on a wild adventure across different dimensions to find the parts needed to destroy the power - stealing device.
