Also Cerulean Cave had super strong pokemon. Why is that? Maybe Mewtwo trained them? Perhaps a genetic thing, that allows them to be super strong? What keeps Mewtwo restrained? He could just walk out the hole and kill the guard. I don't think that's hard. Referring to the war, wouldn't there be any mention of the war in the entire Kanto region? I do agree with the genderless pokemon could breed in their own way, as well as Phione evolving. Also the person who guarded the Cerulean Cave, could have had potential access to the cave as well. Which leads to my next question. What happened to the cave? Water submerged it? That theory could be used, as inside the cave water was filled in. Although it doesn't explain if the user couldn't just dive into the water, and enter the cave. Although dive wasn't introduced wouldn't it be possible to dive in, if the Hohen region introduced it? Also there is no mention of Johto or Kanto in the Hoenn region. Also what's up with the little rocks blocking up the sea? In the Pokemon Universe, there is rocks blocking the ocean (For obvious reason, going any further would glitch up the game.) But, what would it lead to?
