Pokémon Steam

A French fan-made Pokémon game in which you embody the son/daughter of the Champion and try to be one in your turn in an all-new region named Exodius.

During the world creation, Arceus - god of Pokémons - was attacked by a "dimensional Pokémon", severely injuring it in one blow. To face this terrible threat, Arceus called Palkia, Dialga and Giratina as reinforcements.

After a fierce fight, the four legendary Pokémons had just enough strength to stand up to this mysterious Pokémon. They miraculously managed to force him back into his dimension.
