In fanfiction, the characters could interact during a global crisis. Let's say an ancient evil is rising that combines magic and advanced technology. The Justice League realizes they need the help of the wizards from Harry Potter's world. So, they send representatives like Superman and Wonder Woman to Hogwarts. There, they meet Dumbledore and the students. The students are excited to see these super - heroes and together they form a plan to fight the evil. They combine the super - powers of the Justice League with the magic of Hogwarts to defeat the enemy.
The characters from these different universes would have very diverse interactions. For example, Harry Potter characters are used to magic, but the superpowers of the Justice League would be something new and astonishing to them. Meanwhile, the horror elements of Silent Hill would be a shock to both the magical and super - powered groups. Superman might try to protect the students of Hogwarts from the Silent Hill monsters, while Hermione would be fascinated by the technology of the Justice League's gadgets and try to learn from them.
In fanfiction, they might interact due to a misunderstanding at first. Maybe the Justice League sees Ben using his alien powers and thinks he's a threat. But then they learn that there are other forces at work that are endangering both their worlds. So they start to communicate and plan together. Ben can show the League his knowledge of different alien races and technologies, while the League can share their experience in dealing with big - scale threats on Earth.
Hermione Granger could have an interesting interaction with Batman. Both are highly intelligent and strategic. Hermione could share her knowledge of magic and ancient texts, while Batman could teach her some detective skills and how to use technology in combat situations.
They could interact in various ways. For instance, Naruto might be in awe of the Justice League's high - tech gadgets and superpowers at first. The archangel could start by explaining to Naruto how the Justice League operates. Then, characters like Batman might be interested in Naruto's stealth and detective - like skills, which are similar to his own in a way. The archangel could also use its powers to help the team communicate, since they come from different universes with different languages.
The characters interact in various ways. Danny could be called upon by the Justice League to deal with a particular threat that has a connection to the Ghost Zone. He would then have to work alongside heroes like Superman or Batman. Superman might be curious about Danny's powers, as they are so different from his own. Batman, of course, would be analyzing Danny's abilities and trying to find any potential weaknesses. Danny's enemies from his own series could also be involved, and the Justice League would have to learn how to deal with these new types of foes.
Well, Naruto himself would be very curious about the Justice League. He would probably be excited to meet heroes with such different powers. He might try to show off his own skills a bit at first. As for the League, Superman would likely be intrigued by Naruto's chakra - based powers. He would want to understand how they work compared to his own superpowers.
They would probably start by being cautious of each other. Then they'd start to exchange skills and knowledge.
Batman would likely be very cautious around the Avengers at first. He'd be observing their tactics and technology. Thor, on the other hand, might be curious about the Justice League's powers, especially Superman's strength. He might challenge Superman to a friendly test of strength.
In a fanfiction, Noctis and his friends could be summoned to Hogwarts by Dumbledore because he senses a great danger approaching that only their combined powers can defeat. Noctis might initially be suspicious of the wizards, but as he gets to know Harry and his friends, he realizes they share the same goal of protecting their respective worlds. They could then train together, with Noctis teaching the wizards some combat techniques and the wizards teaching Noctis about spells.
Hermione could use her vast knowledge of magic and research skills to study Orochi. She might try to find a way to communicate with it, thinking that there could be a rational explanation for its existence and actions. Harry, on the other hand, might be more cautious and initially see Orochi as a threat. He would approach it with his Gryffindor courage, but also be ready to defend himself and his friends.
