As previously reported, Pokémon Black/White 2 will introduce Keldeo, a new legendary Pokémon with multiple forms. In his regular form, Keldeo looks like the art work we’ve seen of him before:
However, Keldeo is also part of the new Kyurem vs. The Sacred Swordsman Keldeo movie. If you bring the Keldeo from the special event associated with this movie into the game, and take it to Sangi Forest, it will learn the move “Secret Sword,” which will make him take on his Resolution form:
Below are a few screenshots of Keldeo in the game. He’s also in the Pokédex 3D Pro app, and you can take a look at this 3D model after the screens.
