Pokémon Pearl is a traditional Pokémon RPG that takes place in a region called Sinnoh.In the Sinnoh region, there are two Pokémon that symbolize the region. They appear in the Sinnoh reigon's myths and old folklore. One is called Dialga, and is said to have the power to control time. The other is called Palkia, who is said to have the ability to distort space. The sinister organization called Team Galaxy is trying to rule the region by utilising these two Pokémon's power. During your adventure to complete your Pokedex and become the Champion, these two Pokémon, and Team Galaxy, intertwine into the story and lead you on a fantastic journey across the Sinnoh region.When you set off on your travels, you play as either a boy or girl Trainer. You can utilise the DS's dual slots to transfer Pokémon from the GBA Pokémon games and you can link up with Pokémon Ranger to access more special content. Pokémon fans have caught glimpses of Mime Jr., Lucario, Munchlax and Weavile in Pokémon movies, and these Pokémon feature in this game.
