Pokemon Pearl

Pokemon Pearl is a fan-made idea, this is not leaked information and I do not own the rights to Pokemon.

Plot
As the plot continues, the protagonist encounters the main antagonists, Team Galactic, although their motives are unclear until later. Team Galactic captures Uxie, Azelf and Mesprit, of Sinnoh’s three lakes, and imprisons them, making it the protagonist's responsibility to free them. Upon releasing the trio, he is able to travel to the sacred shrine atop Mt. Coronet and enter the cave, where the leader of Team Galactic awakens either Dialga in Diamond, or Palkia in Pearl. Dialga or Palkia’s powers begin to overwhelm Sinnoh, causing the newly free Uxie, Azelf, and Mesprit to attempt to stop it. It is then that the protagonist is able to engage in a battle with (and has a chance to capture) the version-appropriate Legendary Pokémon. Having completed this, and after meeting requirements set by the Elite Four, the player is able to contend with them, fighting its members and then the Pokémon League Champion, Cynthia.
