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.

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 a crossover where the characters from 'Harry Potter' and 'Beyond Two Souls' meet in a magical realm. For example, Jodie Holmes could use her powers to enter the wizarding world. Maybe she helps Harry Potter solve a mystery that involves a dark force that is connected to both their worlds, like a powerful entity that feeds on fear and uses the unique magic systems of both universes to grow stronger.

One possible plot could be that the Smurfs accidentally find a magical portal that leads them to the wizarding world of Harry Potter. They could be initially confused but then start to explore.

And they could also get involved in some of Harry's adventures, helping him out in their own little ways.

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.
