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.
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.
Godzilla was obviously one of the main characters. There were also likely some human characters who were either trying to stop Godzilla or study him. Maybe some military personnel. But overall, Godzilla was the central figure driving the action and the story in the 1970s Godzilla Marvel Comics graphic novel.
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.
No, the 1954 Godzilla movie was one of Godzilla's earliest works, but it was not the earliest. The name Godzilla first appeared in a Japanese manga of the same name in 1942. Before that, there were other forms of Godzilla's image, such as appearing in news reports, posters, and advertisements.
