Well, Ash's Mega Charizard in fanfiction is a popular topic. Many writers like to explore the new abilities it gains when it mega - evolves. It might have enhanced fire - based attacks that are more intense and have a wider range. Also, it could be portrayed as having a more dominant and confident personality compared to its non - mega form. This can lead to interesting storylines where it's not just about the battles, but also about how Charizard's new form affects its relationships with other Pokemon and Ash's team.
One idea in fanfiction could be that Ash discovers a special item that enables his Charizard to mega evolve again, but into an even more powerful form. This new mega form might have different coloration and enhanced fire - based abilities. It could breathe a type of blue - flame that is hotter and more destructive, making it a force to be reckoned with in battles.
One possible fanfiction could be that Ash discovers a new power within Mega Charizard Y during a crucial battle. This power could be a unique type of fire blast that has the ability to heal his Pokémon as well as damage the opponents. The story could revolve around Ash training Mega Charizard Y to master this new power and use it to defeat a powerful villain in the Pokémon world.
One thing that makes it special is its power. It's usually depicted as being much stronger than regular Charizard, able to defeat tough opponents with ease. For instance, it can take on multiple strong Pokemon at once. Another aspect is the loyalty to Ash. In fanfiction, this loyalty is often shown through its willingness to put itself in danger to protect Ash. It's like a super - powerful protector.
There's a fanfiction called 'Charizard's Evolutionary Journey with Ash'. It's interesting as it looks at how Charizard continues to evolve in terms of its power and its connection with Ash. It has some unique plot twists where Charizard has to use new and unexpected moves to save Ash from difficult situations.
It's possible that he received it as a gift from Professor Oak. Oak might have discovered a way to transfer Mega Stones across regions and sent the Charizardite to Ash in Sinnoh. Another option could be that Ash made a trade with another trainer. He traded one of his Pokémon for the Mega Stone, knowing the potential of Mega Charizard.
The popularity comes from the fact that Ash and Charizard's story in the original series left room for more. Their relationship had its ups and downs, and fanfiction fills in those gaps. Fans can create stories where Charizard overcomes its pride issues more fully, or where Ash uses Charizard in more strategic battles. It's all about expanding on what was already a beloved part of the Pokemon franchise.
Some fanfictions explore the idea of the two Pokemon learning from each other. After the battle, whether it's a win, lose or draw, they might exchange some sort of knowledge or experience. Maybe Greninja learns how to be more aggressive from Charizard X, or Charizard X learns about agility from Greninja. There are also plotlines where the battle is a test of friendship or loyalty between the Pokemon and their trainers.
In fanfiction, it really depends on how the author writes it. But generally, Ash Greninja has incredible speed and agility, along with strong water - type moves. Mega Charizard X, on the other hand, is a powerful fire - type with enhanced stats. If the battle takes place near water, Ash Greninja might have an advantage. However, if it's in an open, dry area, Mega Charizard X could be more dominant.
Fanfiction writers sometimes give Ash's Pokemon mega evolutions that are related to the environment or a specific location. For example, if Ash is in a snowy area, his Snorunt could mega evolve into a form that is better adapted to the cold. It could have ice - based attacks that are more effective in the frigid climate, and its body might be covered in a thicker layer of ice for protection. This kind of portrayal adds an interesting layer to the story and the battles that Ash participates in.
