What could be an interesting plot in a Harry Potter and Smurfs crossover fanfiction?

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 idea could be that Carly and her friends discover a magical portal in their apartment that leads to Hogwarts.

They end up teaming up to solve a mystery that involves both the wizarding and Muggle worlds.

One interesting plot could be that the wizards from Harry Potter world accidentally stumble upon the Shire while on a magical experiment gone wrong. They meet the hobbits and learn about their simple yet fulfilling lives. Meanwhile, the hobbits are in awe of the magic the wizards possess. Then, an ancient evil that threatens both the wizarding world and Middle - earth emerges, forcing them to combine their strengths. The wizards use their powerful spells and the hobbits' courage and resourcefulness to fight against it.

One idea could be that the magical world of Harry Potter has a security breach that the Incredibles are called to help with. Mr. Incredible could use his strength to move heavy magical objects or hold back magical creatures, while Elastigirl could reach into tight spaces in Hogwarts to retrieve lost magical items. Dash could be useful in quickly delivering important messages across the vast Hogwarts grounds. And Violet's force fields could protect students from dangerous spells.

Perhaps there could be a plot where a powerful dark wizard in the Harry Potter universe creates a spell that merges the two worlds. This causes chaos as ninjas and wizards start to clash due to misunderstandings. Naruto and Harry, realizing the danger, form a group of their friends from both worlds. They include Hermione, Ron, Sasuke, and Sakura. Together, they try to find a way to reverse the spell while also learning from each other. Naruto teaches the wizards about chakra control, and the wizards teach the ninjas about potions and magical creatures.

Well, it could be that a dark wizard in the Harry Potter universe discovers the ADAM and plasmids from Bioshock. He starts using them to create an army of super - powered Death Eaters. Harry and his allies have to figure out how to counter this new threat. They might travel to Rapture to find a way to neutralize the ADAM or find some kind of magical antidote. Harry could use his Patronus charm to fend off the more deranged splicers, and the Weasley twins could use their prank - making skills to mess with the Big Daddies.

One possible plot could be that Hogwarts starts a new course on Pokemon magic. Harry and his friends discover Pokegirls are actually a new form of magical creature. They have to learn how to interact with them and use their unique abilities in the wizarding world battles. For example, Hermione might be really interested in studying the Pokegirls' special powers and how they relate to magic theory.

One interesting plot could be that the characters from Harry Potter accidentally find themselves in the Grimm's fairy - tale world. Harry, Hermione, and Ron could encounter classic Grimm characters like the Big Bad Wolf or Cinderella. They might have to use their magic to solve the problems in this new world, such as helping Cinderella without using magic that would violate the Grimm world's rules. And they could also learn some new magic or skills from the Grimm world that they can bring back to their own world.

A possible plot is that a dark wizard from the Harry Potter world tries to take over Arendelle. Elsa and Anna have to team up with Harry and his friends to stop this threat. The Frozen characters would be introduced to the concept of the Deathly Hallows and Horcruxes. Elsa's ice powers could be a key factor in fighting the dark magic. Maybe her ice can counter some of the dark spells, and together they all discover new ways to combine their unique abilities to defeat the evil wizard.

One possible plot could be that Wolverine somehow gets transported to the wizarding world. He could be mistaken for a dark creature at first because of his claws and rough appearance. But then he teams up with Harry Potter to fight against a new dark wizard who has the power to control metal, which poses a great threat to both the Muggle and wizarding worlds. Wolverine's healing factor and combat skills, combined with Harry's magic, would make for an exciting adventure.
