Used to be the most powerful
Pokemon in the world. But then things started getting pretty complicated, and all the
Pokemon became Gods with power over every single thing in the world. Then Arceus came along and said "GTFO," so Mewtwo had to sink back into the shadows and stay there until the last page of the
internet. Now they got some Yin Yang
Pokemon, who are rumored to be able to control Arceus, which makes no sense since Arceus is supposed to be the creator of the universe, and I don't really don't think Arceus would create it's creators. So then a bunch of fans rose up and said "I am disappoint," and Nintendo's trying to make it look like they're making it like their favorite games, Red and
Blue. But really it's just a bunch of BS, and so people kept saying "I am disappoint," so now Nintendo's just keeping going. And now I am going to play Crystal.
