Based on the title, Evil Ash is surely one of the main characters. But without reading it, it's hard to say who else might be involved. It could be characters from the original source material that Evil Ash has a relationship with, like his friends or enemies.
Evil Ash is the obvious main character here. As for others, it might be characters that are specific to the fanfiction world created by the writer. They could be new characters introduced to react to Evil Ash's betrayal, or it could be other well - known characters from the franchise that Evil Ash is from, who are affected by his betrayal. For example, if it's related to a movie franchise, there could be sidekick characters or love interests of the original Ash who are now at the mercy of Evil Ash's betrayal.
Obviously, Ash is one of the main characters. He's the one who experiences the betrayal and then transforms into a badass.

I'm not entirely sure specifically about this 'evil ash betrayed fanfiction' as there could be many different interpretations. It might involve the character Evil Ash in a situation where he betrays someone or something within the context of the fan - created story.
Some fanfictions might have Misty betray Ash. Perhaps she gets lured by the promise of power or some valuable reward. She could be tricked into believing that Ash is no longer the friend she thought he was and that betraying him is for the greater good.
It could be that there is a young, impressionable character who looked up to Ash Aura. After the betrayal, this character is confused and starts to question his own beliefs. There might also be a powerful mage in the story who has the ability to see the truth behind Ash Aura's actions and is trying to prevent the chaos that the betrayal has caused.
The main characters are clearly Ash and Dawn. Ash is a well - known Pokemon trainer, always eager to catch new Pokemon and become a Pokemon Master. Dawn is also a trainer, and in this fanfiction, their relationship is central, especially with the theme of betrayal involved.
The main character is surely Ash. He is the one who is being betrayed. Mew is another important one. It might be that Mew is the cause, directly or indirectly, of Ash's betrayal. Then, Ash's Pokémon partners are likely to be main characters too. They might be confused or forced to side against Ash. And there could be some antagonists in the story, perhaps some evil trainers or organizations who are behind the plot to make Ash look bad and get betrayed.
The main characters are Ash and May, of course. Ash is a well - known Pokemon trainer with a passion for catching and training different Pokemon. May is also a trainer who has her own goals and journey in the Pokemon world. In this fanfiction, their relationship takes a turn due to the betrayal aspect.
Ash is the central character for sure. Then there could be some new characters created specifically for the fanfiction. They might be the ones who instigate the betrayal. For example, a mysterious trainer who has a grudge against Ash. His friends in the Alola region play a big role too. They are the ones whose reactions to the so - called betrayal by Ash form a major part of the story. Pikachu, as Ash's most loyal pokemon, is also a key character as it has to deal with the situation where Ash is being betrayed.
