Ever since the latest update (As of April 7, 2013), tons of fanart has been leaking out on artistic websites and personal websites. While art is being shared, tons and tons of theories have been tossed out and some to be rumored. Some with new forms, like Deoxys and the space rocks, or maybe a clone of a clone. Or, my personal least favorite, Mewtwo evolving or morphing with Mew to make a totally new Pokémon. What do you think is the most reasonable theory?
