The 'godzilla minus one story' might be about a scenario where Godzilla is somehow diminished or in a state different from its usual powerful self. It could involve a plot where Godzilla has lost some of its strength, or there are factors that reduce its threat level in an unexpected way.
I'm not entirely sure as I haven't read it yet. But it might be about Godzilla in some sort of reduced or different state compared to the usual Godzilla stories. Maybe it features a version of Godzilla that is weakened or has some special condition.
The story behind Godzilla Minus One could be a reimagining of previous events or a completely new adventure. It might have updated special effects and a modern twist to keep fans engaged.
I'm not sure who the main characters in the 'godzilla minus one story' are exactly. However, it's likely to include some sort of protagonist who is either trying to understand the change in Godzilla or is directly involved in dealing with the consequences of Godzilla being in this 'minus one' state. There could also be antagonists, perhaps those who want to take advantage of Godzilla's weakened state for their own gain, or those who accidentally caused Godzilla to be in this state in the first place.
The main protagonist from the movie is often a popular character in fanfiction. Writers like to further develop his character arc, exploring his fears, hopes, and growth throughout the Godzilla - related events.
Another concept could be alternate endings or different ways the battle with Godzilla could have gone. For example, some fanfictions might have the humans using more creative or unexpected strategies to defeat Godzilla, rather than the ones shown in the movie.
A really interesting fanfiction might be set in an alternate universe where Godzilla is a protector of the Earth in a more direct way. Instead of just being a force of nature that causes destruction, he actively defends the planet from various threats, and the story could explore his relationships with different species on Earth.
