Hear me out, I'm aware that main series characters like Bugsy are mentioned in the game. Also the fact that there's actual Pokemon available throughout the game oppose to fakemon, kind of makes this a dumb idea. But I think the Pokemon Reborn world is set in an alternate universe or possibly an alternate timeline of sorts. I'm somewhat early in the game, so if this has been answered in the story already, ignore this. I don't want to be spoiled. I just wanted to discuss a theory. All be it, a generic one.
