What could be an interesting plot for a Harry Potter and The Incredibles crossover fanfiction?

Well, in this crossover fanfiction, perhaps Syndrome creates a device that can absorb chakra and targets Naruto. The Incredibles get involved when they see the chaos caused by Syndrome's new weapon. Dash could use his speed to help Naruto outrun the initial attacks, while Naruto teaches the Incredibles some ninja techniques for stealth and perception. They combine their powers to take on Syndrome and his minions.

One possible plot could be that Naruto is somehow transported to the world of The Incredibles. He teams up with the Incredibles family to fight a new villain who has the power to steal ninjutsu. Naruto teaches the Incredibles some basic ninja skills like stealth and using chakra to enhance their physical abilities, and in return, they help him understand the modern world he finds himself in.

Well, perhaps the Infinity Stones somehow end up in the world of The Incredibles. This attracts the attention of both the Avengers and the Parr family. The two groups initially have some misunderstandings as they try to claim the Stones. But then they realize that a powerful new villain, created by the combined energy of the Stones, is emerging. So, they join forces. Dash's super - speed could be useful for quickly transporting the Stones, while Thor's lightning powers could help in battles against the villain's minions.

A plot might involve a villain who has stolen some of Syndrome's old tech and is using it in combination with the technology from Big Hero 6's universe. The Incredibles and Big Hero 6 team up to track down this villain. Frozone could use his ice powers to freeze some of the overheating tech created by the combined bad - guy tech. Honey Lemon's chemical - based gadgets could be used to counteract some of the effects of Syndrome's old inventions. And Jack - Jack, with his multiple powers, could provide some unexpected solutions and comedic relief during their adventure.

Well, perhaps the magical creatures from the Harry Potter universe end up in the '300' setting. Dragons could be used by the Spartans to fight their enemies. The centaurs could also join the battle, lending their archery skills. And Harry could learn some combat skills from the Spartans, which he could then use back in the wizarding world to fight Voldemort's Death Eaters.

One possible plot could be that the Incredibles' city is suddenly facing a new kind of threat that involves some high - tech villains who can climb walls like Spider - Man. Spider - Man, while on a trip to this city, stumbles upon the chaos. He teams up with the Incredibles. Mr. Incredible is impressed by Spider - Man's agility and web - slinging skills. Together, they fight the villains, with Elastigirl using her stretching abilities to reach places Spider - Man can't easily get to and Dash using his speed to distract the bad guys while Spider - Man goes in for the final web - capture.

Well, perhaps the Death Note from the Bleach universe gets mixed up with the magic in Harry Potter's world. A powerful wizard could get hold of it and start using it in ways that disrupt the balance of life and death in both worlds. Harry and his friends would have to figure out how to stop this misuse, with the help of some Bleach characters who understand the true nature of the Death Note.

One idea could be that Eragon, while on one of his adventures in Alagaësia, accidentally creates a portal that leads him to Hogwarts. There, he meets Harry Potter and they quickly realize they have a lot in common. They could team up to fight against a dark force that somehow threatens both their worlds, like a new type of dark magic that combines the magic of Alagaësia and the dark arts from the wizarding world.

In a more comical plot, Hagrid could accidentally stumble upon a small Transformer while in the Forbidden Forest. Thinking it's a strange magical creature, he brings it back to Hogwarts. The Transformer, being a bit lost in this new magical world, causes all sorts of chaos in the castle. Harry and his friends have to figure out how to get the Transformer back to where it belongs while also dealing with the daily challenges at Hogwarts.

One possible plot could be that the Duel Monsters from Yu - Gi - Oh! are introduced to the wizarding world of Harry Potter. Wizards start using them in duels instead of their traditional spells. Harry and his friends have to learn the new rules of these duels and face off against a dark wizard who has mastered the most powerful Duel Monsters.
