One possible plot could be that Godzilla somehow arrives in the Pokemon world. The Pokemon trainers initially see Godzilla as a huge threat and try to battle it with their strongest Pokemon. But then they realize that Godzilla is not there to cause chaos but is being chased by some powerful and evil force from its own world. So, the trainers and their Pokemon team up with Godzilla to fight this common enemy. This would involve epic battles between the combined forces of Pokemon and Godzilla against the evil force, with lots of strategy and unique power combinations.
The plot might also involve Godzilla being a sort of 'legendary Pokemon'. In this fanfic, Godzilla could have its own set of unique moves that are much more powerful than normal Pokemon moves. Trainers from all over the world would then be on a quest to find and catch Godzilla. However, Godzilla is not easy to catch or control. Some trainers might try to use underhanded methods to get it, which could lead to a conflict among the trainers themselves, while others would respect Godzilla's power and try to befriend it in a more ethical way.
Another idea is that Godzilla's presence in the Pokemon world starts to disrupt the natural balance. For example, its sheer size and power could be causing earthquakes and other natural disasters. A group of elite Pokemon trainers and their Pokemon must figure out a way to either send Godzilla back to its own world or find a way to coexist with it. They could start by researching Godzilla's biology and behavior to find a solution. Along the way, they would face many challenges and have to make tough decisions about whether to use force or diplomacy.
A possible plot could be that Godzilla is accidentally teleported into the Pokemon world. The Pokemon trainers think he is a new, extremely powerful and dangerous 'Pokemon'. So they try to stop him. But as they try to fight Godzilla, they realize that their normal attacks have little to no effect. Then, a group of legendary Pokemon, such as Arceus and Lugia, decide to communicate with Godzilla. They find out that Godzilla is just as confused as they are about this new world. Together, they try to find a way to send Godzilla back to his own world while also dealing with the chaos that his presence has caused in the Pokemon world, like disrupted ecosystems and panicked Pokemon.
Well, it could be about the Total Drama characters getting transported into the Pokemon world. They might start their own Pokemon journey, with each character having a unique Pokemon team based on their personalities. For example, the more aggressive characters could have strong and fierce Pokemon like Tyranitar or Gyarados.
The Pokemon characters would likely be in awe or fear of Godzilla at first. Smaller Pokemon might hide behind their trainers or larger Pokemon companions. Trainers, being the more inquisitive ones, would try to assess Godzilla's intentions. Some brave trainers might approach Godzilla with caution, trying to communicate using their Pokemon's abilities like telepathy or by using signs. Godzilla, on the other hand, might not understand the Pokemon world's rules and customs at first and could accidentally cause destruction while just moving around.
It could be about Godzilla emerging in the world of Evangelion. Maybe the Angels in Evangelion are confused by this new giant monster. The Eva pilots might have to deal with both Angels and Godzilla at the same time.
Once upon a time, in a strange new world where the boundaries between reality and fantasy were blurred, Godzilla emerged into the Pokemon universe. Pikachu was the first to sense the great beast's arrival. The electric mouse Pokemon was both terrified and curious. Godzilla, on the other hand, was confused by this new land filled with small, strange creatures. As he stomped through the forest, he accidentally knocked down a nest of Pidgey. The Pidgey were angry and began to attack Godzilla, but their small beaks and feathers did little to harm the giant. Meanwhile, trainers from all over the region came to see what was causing the commotion. One brave trainer decided to try and capture Godzilla with a Pokeball, but it was immediately destroyed by Godzilla's atomic breath.
A plot could involve a mad scientist in the RWBY world who tries to recreate the power of Godzilla using Dust. However, the experiment goes wrong and starts to attract the real Godzilla. The RWBY teams then have to deal with the chaos caused by the approaching Godzilla. They might think that Godzilla is there to destroy their world, but as they fight, they discover that Godzilla is actually attracted to the unstable energy that the mad scientist created, which is also a threat to the balance of their world. So, they have to find a way to work with Godzilla to neutralize the dangerous energy source.
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.
Well, one possibility could be that Godzilla somehow ends up in the wizarding world. Maybe a powerful dark magic spell goes wrong and creates a portal that sucks Godzilla in. Harry and his friends at first think it's a new kind of dark creature created by Voldemort. They try to fight it using spells, but soon realize that Godzilla is not exactly evil. Godzilla might then start causing destruction in Hogwarts, and the wizards have to figure out a way to either send it back or control it without killing it.
One possible plot could be that Godzilla emerges in the Naruto world during a time of great unrest. The shinobi are initially terrified but Naruto, with his never - give - up attitude, decides to try and communicate with Godzilla. Maybe Godzilla is there because it senses a great evil in the Naruto world that is similar to the threats it has faced in its own. Naruto and his friends then have to figure out a way to work with Godzilla to defeat this common enemy.
One idea could be that the Pokemon are brought into the Naruto world and are seen as strange chakra - infused creatures. Naruto himself could befriend a Pikachu - like Pokemon that has a special jutsu - like ability. For example, it could use electric attacks in a way similar to how Naruto uses his Rasengan. The Pokemon trainers could be seen as a new type of ninja, with their Pokemon being their summons.
