The Pokémon Brilliant Diamond and Pokémon Shining Pearl games are set in the Sinnoh region.

Rich in nature, with Mount Coronet towering at its heart, Sinnoh is a land of many myths passed down through the ages.

The Protagonist

A famous professor in the field of Pokémon Evolution recruits you to travel across the Sinnoh region to complete an encyclopedic record of Pokémon known as a Pokédex.

Choose your appearance at the beginning of your adventure.

First partner Pokémon

Before you set off on your journey, you’ll choose Turtwig, Chimchar, or Piplup to be your first partner Pokémon.


  • Made from soil, the shell on its back hardens when it drinks water. It lives along lakes.
  • It undertakes photosynthesis within its body, making oxygen. The leaf on its head wilts if the Pokémon is thirsty.


  • It agilely scales sheer cliffs to live atop craggy mountains. Its fire is put out when it sleeps.
  • Its fiery rear end is fueled by gas made in its belly. Even rain can’t extinguish the fire.


  • Because it is very proud, it hates accepting food from people. Its thick down guards it from cold.
  • It lives along the shore in northern countries. A skilled swimmer, it dives for over 10 minutes while hunting.

Become the Champion

As you travel across Sinnoh filling out your Pokédex, you’ll challenge the strongest Pokémon Trainers in each town: the Gym Leaders.

Defeat Gym Leaders to receive Gym Badges as proof of your victories. Collect all eight Gym Badges to compete in the Pokémon League, where the highest-level Trainers—the Elite Four and the Champion—await.

Win your way through the Pokémon League to earn the title given to only the strongest Pokémon Trainer: Champion!
