10th Movie Clooz

According to PokeAni.com, Dialga vs. Palkia, the next Pokémon movie, will also feature a Diamond and Pearl event-only legendary Pokemon (which are either Sheimi, Arseus, or Darkrai). The Pokemon will be revealed in next month's issue of CoroCoro on February 15th. If you read the Diamond and Pearl in-game legend that is posted, understand it, and the legend turns out to be true, you may already know who the Pokémon is (I know who the legend refers to, but the legend relating to the movie is another story).
