As we all (probably) know, X and Y will be based on Genetics, DNA, etc. The Japanese logo shows a bit of DNA and the games are named after Chromosomes, X and Y. If this is so, what role will Genetics play in the Plot of the Games? I'm going to make two lists: My Predictions and My Hopes.
The enemy team will try to clone Pokemon to make an army of strong Pokemon
The leader will try to clone Yveltal or Xerneas because of their rarity and use it as his (or her) Pokemon against its will
Mew and Mewtwo will return (Mewtwo being a clone) and have some relevance to something in the plot
More info on Genesect and Kabutops and maybe more like that (Think Robo-Aerodactyl:ksmile::ksmile:)
More fusions (maybe)
Mutations of Pokemon (again, maybe)
Please post your own!
