It's official: Shaymin to co-star in Movie 11
Details from the March issues of Coro Coro Comics and Famitsu magazine have revealed the full title and co-star of the 11th Pokémon movie, Giratina and the Sky's Bouquet: Shaymin. Details are still being reported from Japan, but Shaymin's Ken Sugimori art and some additional movie plot points have been divulged.
For example, Giratina has two forms: "another form," which is seen in the movie poster and Diamond and Pearl games, and an "origin form," which has yet to be seen. The origin form is seen when Giratina moves between dimensions.
The magazines also cover the Nintendo DS game Pokémon Ranger Batonnage, which will be released March 20 in Japan.
