In terms of character interactions, Naruko would bring her energetic and determined personality to the Rosario Vampire world. She would be eager to learn about their magic and powers. The vampires, on the other hand, would be fascinated by Naruko's ninja abilities. Inner Moka could challenge Naruko to a friendly sparring match to test their strengths. Tsukune would try to mediate between them if things got too intense. And the other characters from both worlds would gradually start to understand and respect each other as they interact more. For instance, Naruto's loyalty to his friends could inspire Tsukune to be more assertive in protecting his friends in the Rosario Vampire world, and the Rosario Vampire characters' acceptance of their differences could teach Naruko's friends a lesson about tolerance.
Naruto would probably be very curious about the vampires and other creatures in Rosario Vampire. He'd be his usual friendly self, trying to make friends.

Tsukune, from Rosario Vampire, could learn a lot from Naruto about determination and fighting spirit.
Max Steel would probably be very cautious at first in the Rosario Vampire world. He's used to a more technological and human - centered world. Tsukune could be curious about Max's powers and technology. And Max might be intrigued by Tsukune's ability to adapt to the monster world. Moka, on the other hand, might see Max as a potential ally or a threat depending on how he behaves around her and the other monsters.
In a Naruko x Rosario Vampire crossover fanfiction, the plot could center around a tournament. The idea could be that both the ninja world and the Rosario Vampire world participate in a grand tournament to prove which world has the stronger fighters.

This would lead to some interesting battles and also some unexpected friendships as they learn about each other's cultures and fighting styles.
The characters would have very interesting interactions. Naruto would probably be curious about the vampires and their powers. The vampires, on the other hand, might be wary of Naruto at first. And if there's a dragon character, it could be a source of awe for everyone.

Well, Naruto's friendly and determined nature would likely make him try to befriend the characters from Rosario Vampire. He might be initially confused by the different species and powers there.

But Naruto could be the bridge between them, showing the Rosario Vampire characters that there's more to power than just intimidation.
The demigods from Percy Jackson are used to a certain code of honor and a hierarchy. In a fanfiction, when they meet the characters from Rosario Vampire, there could be clashes in values. For instance, some of the more aggressive demigods might not trust the vampires at all, thinking they are all just blood - thirsty monsters. But then they might learn that some of the vampires in Rosario Vampire are more complex, like Moka, who has a good side. And this could lead to a change in their views and the start of an interesting friendship or alliance.
If we consider the Hulk, he would be a very intimidating presence to the vampires. But the vampires, especially someone like Klaus Mikaelson, wouldn't be easily intimidated.

For example, if a vampire tries to attack him with speed, he can send out clones to surround and counter - attack.
In a fanfiction, Kuyo could interact through a trade of knowledge. The Naruto characters are known for their unique jutsus and combat strategies.
