During battles or difficult situations, they would communicate effectively. Naruto would shout out his plans and strategies, while Rath would use his more technical knowledge to complement Naruto's ideas. Their different personalities, Naruto's boldness and Rath's more calculated approach, would make their interactions interesting and dynamic.
At the start of their interaction in the fanfiction, Batgirl would approach Naruto with a sense of wariness. But Naruto's infectious energy would soon break down that barrier. They would communicate about their different worlds, with Naruto trying to understand the concept of a city like Gotham without ninjas. Batgirl would be fascinated by the chakra system. In combat, they would have to learn each other's fighting styles quickly. Naruto might dash in headfirst, while Batgirl would be more strategic. They would need to find a balance, and through their interactions, they would develop a mutual respect. Naruto would learn from Batgirl's discipline and Batgirl would be inspired by Naruto's ability to bring out the best in people around him.
Naruto would probably be his usual energetic self, trying to figure out who Rosalina is. Rosalina, being a more calm and mysterious character, would be a bit reserved at first. But Naruto's positive attitude might make her open up. They could start by just sharing their stories, Naruto about his ninja training and Rosalina about her duties in the cosmos.
At first, there could be some misunderstandings. Naruto might mistake Ahsoka's Jedi calm for arrogance, and Ahsoka might find Naruto's boisterousness a bit much. But as they spend time together, they'd realize they have a lot in common. Both are strong - willed fighters dedicated to protecting their worlds. They'd start to learn from each other. Naruto could learn about patience from Ahsoka, and Ahsoka could pick up on Naruto's never - give - up attitude. They might even have some friendly sparring matches that help them understand each other better.
Sasuke might be intrigued and also a bit jealous of Naruto's homunculus powers. He'd probably see it as another thing that makes Naruto different and stronger. Sakura would likely be worried at first, but then try to understand and help Naruto control his new - found abilities.
Maybe Naruto and Rath team up to fight a common enemy. Rath has his own set of powers and Naruto has his chakra - based abilities. They combine their strengths, like Naruto using his Rasengan along with Rath's energy blasts to defeat a powerful foe that threatens both of their worlds.
Sasuke might initially be suspicious of King Kong. He would see it as a potential threat to the ninja world. Naruto, on the other hand, would be more open - minded. He would probably try to make friends with King Kong right away. Sakura might be a bit scared at first but then be impressed by King Kong's strength and want to study it in a medical - ninja way to see how such a large creature functions.
Naruto would probably approach Bowser with his usual friendly and curious nature. He might ask Bowser a bunch of questions about his world and his powers. Bowser, being the big, tough villain he is, would likely be initially hostile or dismissive. But Naruto's persistence could break through that. They might end up having a conversation where Naruto tries to convince Bowser to be less of a bad guy, while Bowser tries to intimidate Naruto into leaving him alone.
Naruto would probably be very curious about Leia's world. He might ask a lot of questions about the spaceships and the different species. Leia, on the other hand, would be intrigued by Naruto's ninjutsu. They would start by getting to know each other's abilities.
The interactions could also involve some comical moments. For example, Ironman trying to understand how Naruto can run on water or up trees without any visible technology. And Naruto would be completely baffled by things like Jarvis, Ironman's AI. However, when it comes to serious battles, they would start to respect each other's abilities. Ironman would see the raw power and determination in Naruto, and Naruto would admire Ironman's strategic thinking and advanced weaponry. They would communicate in a mix of broken English (from Naruto) and some basic ninja signs that Ironman would have to learn.
Naruto would probably be very curious about Rapunzel's long hair at first. He might keep asking her how she can control it so well. And Rapunzel would be amazed by Naruto's ninja skills, like when he does his rasengan. She would probably want to learn some of those cool moves. Naruto, being the friendly and helpful type, would be happy to show her some basic ninja stances.
