How would characters from Harry Potter interact with those from Planet of the Apes in fanfiction?

The highly disciplined and technologically advanced Space Marines from Dawn of War would likely view the apes from Planet of the Apes with suspicion at first. The apes, on the other hand, would be wary of these strange, armored beings. However, if they found a common goal, like protecting a valuable resource or territory, they could gradually start to cooperate. For example, the apes could use their knowledge of the local terrain to help the Space Marines in a battle against an enemy that threatens both their existences.

The Gryffindor characters from Harry Potter like Harry himself would probably be very bold and upfront when interacting with the characters in Highschool DxD. They might immediately jump into helping with any dangerous situations. Hermione, with her vast knowledge, could start analyzing the different powers and hierarchies in the DxD world. And Ron might be a bit more cautious but still curious.

Harry might be very curious about the dragon characters in 'Living with Dragon Maid'. He would probably ask a lot of questions about their abilities and their dragon forms. The dragon characters, like Tohru, would be equally interested in Harry's magic. They would likely want to see him perform spells. Harry could also be a bit cautious at first, as he's used to dealing with dangerous creatures in his world, but he'd soon realize that the Dragon Maid characters are friendly.

Hermione would probably be very interested in the historical and magical aspects of King Arthur's time. She might study the old magic used by Merlin and try to apply it to her own spell - casting. For example, if Merlin had a spell for weather control, Hermione would be eager to learn how it worked and if it could be adapted to modern wizarding needs.

Harry Potter would likely be in awe of Hercules' strength at first. He might be a bit cautious too, as Hercules is from a different world of gods and myths. But they would probably quickly become friends as they both have a strong sense of justice. Hermione would be very interested in Hercules' stories about the Greek gods and would constantly ask him questions, trying to learn as much as she could.

Naruto, with his friendly and outgoing personality, would quickly befriend the DMC 5 characters. He would be eager to learn about their world and share his own ninja world experiences. He might even try to teach them some basic ninja techniques, like how to walk on water or climb trees.

The Sith in Star Wars would be a big threat in a combined fanfic. They would likely see the magic in the wizarding world as a new source of power to corrupt. For example, Voldemort and Palpatine could form an alliance. The Jedi and the good wizards would have to put aside their differences and work together. The Jedi's combat skills and connection to the Force, combined with the wizards' magical spells, would be the only way to defeat such a powerful alliance. There would be a lot of drama and action as they fight against the combined might of the Sith and the Death Eaters.

Harry would probably be cautious at first. He's used to the magic in his world, and an Imperial Arm would be something new. He might study it carefully, like he does with new spells. Hermione would be all about researching it, looking for any information she could find. Ron might be a bit more skeptical, but still curious. They would all approach it with the mindset of trying to understand how it fits into their world of magic.

Moana would likely be curious about the magic in Harry Potter's world. She might ask Harry to show her some spells, like the levitation charm. Harry, on the other hand, would be impressed by Moana's courage and her ability to sail across the ocean. He could learn from her about determination. Hermione might study the culture of Moana's island, and Moana could learn about Hermione's love for books and knowledge.

The characters would have very different worldviews. For example, the wizards in Harry Potter are used to a world where magic solves many problems. But the Firefly crew has to rely on their wits, technology and sometimes brute force. So there could be initial misunderstandings. Harry might try to use magic to fix a broken part on the Firefly ship, but Mal might not trust this strange 'power' at first.
