Eren could be really interesting. Given his ability to transform into a Titan, he might be curious about Godzilla and try to understand his power. He could also see Godzilla as a rival in terms of power and might try to prove himself by interacting with Godzilla in some way.
Yang would be a likely character. She's bold and not one to back down from a challenge. She might see Godzilla as a huge opponent to test her strength against. Maybe she'd start off trying to punch it, only to realize that brute force alone won't work and then have to figure out a more strategic way to interact with it.
I think Hulk would be the most interesting. He's all about brute strength and smashing things. Facing Godzilla, he'd be like a tiny but very angry force against a huge monster. It would be a battle of the titans in a sense, and seeing how Hulk reacts to Godzilla's size and power would be really exciting.
Natsu would be a likely candidate. He's always up for a challenge and not afraid to take on powerful opponents. He'd probably be the first to rush towards Godzilla, either to fight it or try to befriend it in his own Natsu - like way.
It could be really exciting. Imagine Godzilla suddenly appearing in the world of Attack on Titan. The Titans would be no match for Godzilla's size and power. Godzilla could easily stomp on the Titans, and the Survey Corps might initially be terrified but then see Godzilla as a potential ally against the Titans.
It's really hard to say. Godzilla has his massive size and powerful atomic breath. But Titans in 'Attack on Titan' are also very large and strong, and some of them are extremely fast. If Godzilla could use his atomic breath effectively, he might be able to take out a lot of Titans quickly. However, if the Titans could swarm him all at once, they might be able to overpower him.
Well, in many of them, the first encounter between Godzilla and the Titans is always exciting. It's like two huge forces colliding. For example, in some stories, Godzilla's atomic breath against the Titans' powers creates a really intense moment.
Naruto would probably be very curious about Godzilla. He might try to talk to it, even though Godzilla can't really communicate in the same way. He'd likely use his friendly and fearless attitude to approach Godzilla. Godzilla, on the other hand, might just see Naruto as a small, insignificant being at first. But as Naruto shows his determination and power, Godzilla might start to respect him in a way.
One interesting pairing could be Godzilla and Hulk. Both are powerful, almost indestructible forces of nature. They could have an epic battle at first, as they both have a tendency to lash out when provoked. But then they could end up teaming up against a greater threat, like a powerful alien invasion. Another great pairing would be Godzilla and Iron Man. Iron Man could use his technology to study Godzilla, and perhaps even try to create some sort of armor inspired by Godzilla's abilities. And Godzilla could provide a physical presence that Iron Man could rely on in a fight. Also, Godzilla and Thor could be a fascinating pair. Thor's god - like powers and connection to nature could be paralleled with Godzilla's own primordial power. They might have a mutual respect for each other's strength.
I think Iron Man and Armin would be an interesting pairing. Iron Man with his brilliant mind and high - tech gadgets could learn a lot from Armin's strategic thinking. And Armin could be amazed by Iron Man's technology and learn new ways to fight the Titans.
It has to be Naruto himself. His never - give - up attitude and his ability to make friends easily would make him a great addition to the world of Attack on Titan. He could inspire the characters in that world, like Eren, to keep fighting even in the face of despair. Also, his unique powers would be really cool to see against the Titans.
