Well, it might be a friendship - based fanfiction. Charizard, being a fire - type, and Meganium, a grass - type, could initially be at odds due to their elemental differences. But as the story progresses, they discover that they have more in common than they thought and form a strong bond. For example, they both might be protecting the same territory from a greater threat, and through their cooperation, they learn to respect and care for each other.
It could be a story about their adventures together. Maybe they meet in a magical forest and have to work together to overcome some challenges, like a group of rogue Pokémon causing trouble.
One element could be the contrast between their types. Fire and grass are quite different, so there could be scenes where they have to adapt to each other's presence. For instance, Charizard might need to be careful not to accidentally set fire to Meganium's surrounding plants.
In this fanfiction, perhaps it's a story of two very different Pokémon coming together. Charizard, being a large and powerful fire - flying type, and Typhlosion, a pure fire type. Their kiss might signify the union of different aspects of the fire element. It could explore how their individual powers combine or interact in a new and exciting way, and how this affects their place in the Pokémon world.
Well, perhaps Ash has returned to Kanto for a Pokemon tournament. As he's exploring the old stomping grounds, he stumbles upon Charizard who has been living in the Charicific Valley. At first, Charizard is a bit hesitant, but then it recognizes Ash. They then go on a journey together through Kanto, revisiting old friends like Brock and Misty, and along the way, they have to deal with some rogue Team Rocket members who are up to their old tricks. This reunion rekindles their unbreakable bond.
Perhaps it's a story where a trainer uses a lemon - scented item to attract Charizard. And then they go on a journey together, with the lemon becoming a sort of symbol or good luck charm throughout their adventures. It could also involve other Pokemon being curious about this lemon - associated Charizard.
Another possibility is a coming - of - age type of story. Charizard, who might be seen as a more experienced Pokémon, could guide Charla as she grows and discovers her own powers. They could go on a journey of self - discovery together, facing various challenges that test their courage and loyalty to each other.
The plot might involve Ash starting his journey all over again, but this time with a Charizard as his very first Pokémon. Since Charizard is a powerful and somewhat stubborn Pokémon, Ash would have to learn how to handle it right from the start. He could face challenges like other trainers trying to steal Charizard because of its rarity. Ash would have to prove his worth as a trainer and his connection with Charizard to keep it by his side.
The plot could be that Ash is orphaned at a young age and Charizard finds him. Charizard then decides to raise Ash in the wild. Ash grows up learning survival skills from Charizard and how to communicate with other Pokémon directly.
The plot could be that Ash enters a Kalos - only Pokémon competition with Charizard. They face strong opponents with unique Kalos Pokémon. Charizard might learn new moves by observing the local Pokémon. For example, it could see a Delphox use a powerful fire - type move and try to adapt it to its own style.
In the 'noibat meets charizard fanfiction', it could be that there is a competition between them. Maybe a race to see who can fly the fastest or reach the highest peak. However, during the competition, they realize that they are both strong in different ways. Noibat's small size allows it to be more agile, while Charizard's strength gives it an edge in endurance. This mutual understanding leads to a newfound respect and they end up as friends.
The plot might revolve around Ash leaving Charizard because he believes Charizard has a greater purpose elsewhere. For example, there could be a group of wild Charizard in need of a leader, and Ash realizes that his Charizard is the one. So he leaves it to fulfill that role. In the fanfiction, we could see Charizard initially being reluctant but then gradually accepting its new destiny and leading the group in a new and better way.
