Not necessarily. There are many powerful characters in Marvel Comics, and Godzilla's strength can vary depending on the storyline and the opponents he faces.
Godzilla might see the pregnant Muto as a threat. After all, Mutos are his enemies. So he could start hunting it down to prevent more Mutos from being born.
Naruto would probably be both amazed and a bit scared at first. But being Naruto, he would quickly jump into action. He might try to use his rasengan against Godzilla, thinking it could do some damage. However, he would soon realize that Godzilla is much more powerful than he initially thought and would have to come up with a different strategy, like using his speed to avoid Godzilla's attacks and find its weak points.
Shinji would probably be terrified at first. He's already hesitant and scared in his normal battles, and Godzilla is much larger and more intimidating than the Angels he usually faces. Asuka would likely be more aggressive, thinking she can take on Godzilla with her Eva. Rei, on the other hand, would be very calm and observant, trying to understand Godzilla's nature. Misato would be in a panic initially, but then quickly start strategizing on how to deal with this new threat. Gendo would see Godzilla as either a new opportunity or a major obstacle depending on his long - term plans.
Some of them might be amused. For instance, Hulk could find it funny if Godzilla was shown as being weak in the fanfiction. He might laugh and say 'That big lizard not so tough!'.
Some of them would be amused. Hawkeye might chuckle at the outlandish scenarios in the fanfic. Black Widow would be more reserved but still interested. She'd be quietly observing and thinking about the implications of the story. Captain America would try to find the moral of the story, if there is one, as he always does.
Ruby would probably be both scared and fascinated. She's always been curious about new things, and Godzilla is definitely something new. But she would also be worried about the destruction it could cause. Weiss might be more cautious and initially see Godzilla as a threat to the order in Remnant. Blake would likely be on guard, observing Godzilla's behavior to see if it's truly hostile or not.
In the 1970s Marvel Comics graphic novel, Godzilla was a huge deal. It brought the iconic monster into the Marvel universe. It allowed for crossovers with other Marvel characters. It was significant as it introduced Godzilla to a new set of fans who were into Marvel Comics, expanding the reach of the Godzilla franchise in a different medium.
A plot could involve a mad scientist in the Marvel universe who, in an attempt to create a super - weapon, accidentally opens a portal to Godzilla's world. Godzilla comes through the portal and starts rampaging. The Fantastic Four, being experts in strange phenomena, are the first to investigate. Reed Richards tries to figure out a way to send Godzilla back while also protecting the city from its destruction. Meanwhile, the X - Men get involved as some mutants start to have strange reactions to Godzilla's presence. For example, Beast might be fascinated by Godzilla's unique physiology and try to communicate with it. Eventually, they discover that Godzilla is actually chasing a powerful energy source that the mad scientist's experiment also attracted. They work together to lead Godzilla to the energy source, which is then used to power a device that sends Godzilla back home.
