The characters' interactions would be complex. Hulk might just charge at Kratos out of instinct, seeing him as a potential challenger. Kratos, on the other hand, might hold back at first, trying to gauge the Hulk's power. Iron Man would likely try to scan Kratos to understand his abilities. Thor could start a conversation about their different pantheons.
Superman would probably be polite but a bit reserved when meeting the Avengers. He'd introduce himself simply and state his purpose, which is usually to help. Iron Man, on the other hand, might be a bit skeptical at first and make some snarky remarks. Thor would likely be more open - minded and see Superman as a worthy ally. Hulk might just be interested in seeing if he can take on Superman in a fight.
Superman would likely be very respectful of the Avengers. He'd be curious about their powers and how they operate as a team. Iron Man, on the other hand, might be a bit wary at first, trying to analyze Superman's powers and find any weaknesses. Captain America would probably admire Superman's strong moral compass and see him as an ally right away. Thor might be interested in testing his strength against Superman's. Hulk could either be aggressive towards Superman or see him as a fellow powerhouse.
Well, Percy's power over water is a very versatile thing. He can make water do all sorts of things like form into weapons or shields. Kratos, with his insane strength, can break through almost anything. In a fanfiction scenario, their powers could combine in battle. Let's say they're facing a horde of fire - based monsters. Percy could call up a huge wave of water to douse the flames, and then Kratos could rush in with his blades and start slashing away at the weakened foes. Also, Percy's ability to heal himself in water could be a great asset if Kratos gets injured. He could find a body of water and help Kratos recover, while Kratos could protect Percy during the process.
Harry would probably be a bit shy at first when meeting the Avengers. But he would soon start sharing his knowledge of magic. The Avengers might be curious and ask a lot of questions. For instance, Tony Stark would be eager to understand the principles behind magic.
Their interaction would be tense at first. Young Kratos, full of energy and unbridled aggression, might see old Kratos as a threat or an obstacle. Old Kratos, on the other hand, would be more reserved and cautious. But as they start to communicate, they would find common ground in their shared past and their connection to their family.
An 'Avengers meets Kratos' fanfiction could be really interesting. Kratos has his own set of moral codes which could clash or align with the Avengers'. Captain America might try to understand Kratos' motives and see if he can be trusted. Black Widow could use her skills to spy on Kratos initially to assess the threat level. And then, as the story progresses, they could find common ground in protecting the world or the universe from a greater evil.
They could interact through combat. Kratos is a very battle - hardened warrior, and Naruto is no slouch either. They could start off as opponents, with Kratos seeing Naruto as a strange and potentially dangerous being in his new world. But as they fight, they come to respect each other's skills.
The interactions would be diverse. Batman from Young Justice's world might have a serious conversation with Captain America about leadership. They both lead their respective teams. Artemis could befriend Black Widow and learn some new combat skills from her.
Thor would likely have a very complex interaction. Since Hela is his sister, there would be a mix of family drama and conflict. The other Avengers might be initially distrustful of Hela. Iron Man could crack sarcastic remarks at her. Captain America would try to keep the peace and assess the situation. Hela, on her part, might look down on the Avengers at first, seeing them as lesser beings compared to her Asgardian power.
The Avengers would also have to adjust to the social and cultural norms of Camelot. They can't just barge in and start making demands. Merlin would have to act as a mediator between the two groups. He would explain to the people of Camelot that the Avengers are there to help, and at the same time, he would make sure the Avengers understand the importance of respecting Camelot's traditions. This interaction would create a lot of interesting storylines and character development opportunities.
