@kaneundertaker2: I'm not sure if the site is eating your posts or you're deleting them after posting them (I can see them in my notifications tab, just not here). But I do think you've made your argument.
While I do think that their isn't enough to differentiate them to be their own unique characters in the same way Elseworlds or What If characters don't have their own pages (most of the time). You seem passionate about them having their own pages and I don't know enough about Pokémon manga to honestly say how different they are.
@kaneundertaker2: I think the problem with those characters is that most of what happens to them is superficial in the grand scheme of things. The Pikachu example wouldn't apply as we consider Pikachu(s) their own character so the fact it evolves wouldn't factor into that decision.
Although, I do think that if the Japanese counterpart of Ash has enough information that can be detailed out, it can be merged with the Ash Ketchum page explaining that he was based on Satoshi as off the top off my head their is no information about his Japanese origins.
