I'm not sure about its popularity. It might be popular among some fans who like to see alternative and edgier takes on the Pokemon story. But it could also be quite controversial as Ash is such an iconic and generally well - liked character, and making him a cheater goes against the common perception of him.
In Ash's adventures in legendary Pokemon fanfics, he often has extraordinary encounters. For example, he might form unique bonds with legendary Pokemon that are not part of the main canon. These fanfics can take his story in new and exciting directions, like having him team up with a Mewtwo in a way that defies the normal Pokemon - trainer relationship. It's all about exploring the untapped potential of his character in the context of the amazing world of legendary Pokemon.
One of the popular fanfics where Ash calls the strongest Pokémon could be those where he summons Arceus. In some fanfictions, Ash might have a special connection with Arceus, the so - called 'God of Pokémon'. This could lead to epic battles and adventures as he teams up with the most powerful being in the Pokémon universe.
I'm not sure specifically what this particular 'ash pokemon ash alola blind fanfic' is about without reading it. It could potentially be a fan - created story where Ash is in the Alola region and has some sort of blindness - related plotline. It might involve his adventures in the Alola region with his Pokémon while dealing with this new handicap, like how it affects his battles or his relationships with other characters.
I think Lucario would be an interesting addition. It's a very intelligent and powerful Pokemon. It could sense danger and help Ash make better decisions. Also, Squirtle is a fan favorite. Its cute appearance and water - type abilities can add a lot of fun to the story, especially in water - related adventures.
One reason could be a sense of over - whelming responsibility. If Ash has too many Pokemon to care for in the fanfic, he might feel he can't give each one proper attention and thus abandons some. Another possibility is if a particular Pokemon has some sort of 'dark side' or uncontrollable power that Ash fears he can't handle, leading to abandonment.
If Red was Ash's father in a Pokemon fanfic, Ash might start with a Pikachu like in the original series, but it could be a special Pikachu that Red had some connection to. Maybe it was a Pikachu that Red had trained briefly or had a unique bond with.
To write a good fanfic in this category, you need to really understand Ash's character. Capture his spirit of adventure and determination. Then, when creating your own character's journey, make it different but still in line with the Pokemon universe. For example, your character could start their journey with a Pokemon that has a special connection to Ash's Pikachu. Develop the relationships between characters well. Show how they interact with Ash, Misty, and Brock. And don't forget to include exciting battles. Describe the strategies used by both the trainer and the Pokemon in detail.
It could be about a fan - created story in the Pokemon universe, specifically related to the 'Pokemon Red' game and a character or concept named Ash. Maybe it's a new adventure for Ash in the 'Pokemon Red' world, with different battles, encounters with rare Pokemon, and unique storylines that the fan has imagined.
