If Conor has some special knowledge or power, like the ability to heal quickly. Achilles, being a warrior, would be both intrigued and perhaps a bit jealous. This could create a complex dynamic between them. Achilles might see Conor as a threat to his status as the greatest warrior at first, but over time, they could come to respect and rely on each other's unique abilities.
Conor might initially be in awe of Achilles. Since Achilles is a great warrior, Conor could look up to him and try to learn from his combat skills. For example, he could ask Achilles to teach him how to use a spear effectively.
They could interact in a way where Conor brings modern - day concepts to Achilles. Say, Conor talks about the importance of teamwork in a different way than Achilles is used to in his military campaigns. This could lead to some interesting debates between them about the best way to lead soldiers in battle.
One plot idea could be that Conor, a modern-day person, somehow gets transported to the time of Achilles. He then has to learn the ways of the ancient world and becomes a squire to Achilles. Together, they face various challenges like battles against mythical beasts that are threatening their land.
Naruto might be intrigued by Nunnaly's calm and gentle nature. He could introduce her to his friends in the Hidden Leaf Village. They could have conversations about their different worlds. For instance, Naruto could tell Nunnaly about his dreams of becoming Hokage, and Nunnaly could share her own hopes for a peaceful world.
Aladdin could be in awe of Hercules' strength. He might ask Hercules to show off his feats of strength, like lifting a huge boulder. Hercules, in turn, would be interested in Aladdin's street - smart ways. For example, Aladdin could teach Hercules how to haggle in the marketplace.
In a fanfic, the ponies and God of War characters could also have a conflict at first. The ponies' values of harmony and love might be at odds with the God of War characters' thirst for vengeance and power. However, as the story progresses, they could find common ground. For example, they could both realize that there are greater threats that require their combined efforts. The ponies could use their magic to help the God of War characters in battles, while the God of War characters could protect the ponies from the more brutal aspects of their world.
They could start as strangers who are initially suspicious of each other. For example, when Ben first arrives in the Avatar world, Aang might think he's a new kind of threat. But as they learn more about each other's powers and intentions, they begin to trust and cooperate. Ben could use his alien forms like Heatblast to help Aang in a fight against a fire - bending enemy, while Aang could use his air - bending to give Ben an advantage in aerial combat.
They could also interact in a more everyday - life - like way. Imagine the Gorillaz inviting the Powerpuff Girls to their home. Bubbles would be excited to see all the cool musical instruments. Blossom would be interested in their creative process. Buttercup might get into a friendly wrestling match with Russel. 2D could draw pictures of the Powerpuff Girls, and Murdoc would try to convince them to be part of his next big scheme. Noodle could cook a meal for everyone, and they would all share stories about their different worlds.
The characters could interact through a magical portal. For example, Naruto might accidentally stumble through a portal into the Please Teacher world. He'd be confused at first but then start to make friends with the characters there, sharing his ninja stories.
Weiss and Iron Man could have an interesting dynamic. Weiss is from a wealthy family in RWBY, and Iron Man is a billionaire. They could bond over their knowledge of high - society and use their resources to fund new projects together. Maybe they create a new type of Dust - powered armor for the RWBY characters.
Well, Ron might be initially terrified of Slenderman. But when his friends are in danger, he would step up. The Weasley twins could try to play pranks on Slenderman, not fully realizing the danger at first. Dumbledore, on the other hand, would be very cautious. He might observe Slenderman from a distance, trying to understand his nature before taking any action. In a 'Harry Potter and Slenderman fanfic', these interactions would create a lot of interesting scenarios.
The characters could interact in combat. For instance, Legolas' archery skills could be compared and contrasted with Naruto's ranged attacks using shurikens. They might train together and learn new techniques from each other.
