You can try looking on some fan - fiction websites like FanFiction.net or Archive of Our Own. There are often a lot of Pokemon - related fanfics on those platforms, so there's a chance you'll find 'pokemon evil ash fanfic' there.
Well, 'pokemon evil ash fanfic' could be about an alternative version of Ash where he turns evil. Maybe he gets corrupted by some dark power in the Pokemon world. It could involve him using his Pokemon in cruel ways or having different goals that oppose the usual values in the Pokemon series.
Obviously, Ash is a central character. Pikachu is also often there, as it's Ash's main Pokemon. Misty and Brock might be in the fanfiction too, trying to figure out what has happened to Ash and how to stop his evil ways. Sometimes, Gary Oak could be involved, either as an antagonist to Ash's new evil self or as someone trying to help bring him back to the good side.
It depends on what you like. If you're a huge Pokemon and Ash fan, it might be great. It could offer a fresh take on the familiar character.
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 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.
Another possible plotline could be that Evil Ash is on a quest to conquer a certain region. Serena, with her own Pokemon, decides to oppose him. Along the way, they both discover new things about the Pokemon world and themselves. Serena might have to team up with other trainers to stand a chance against Ash's newfound power.
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.
