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.

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.

Cyrus, Boss of Team Galactic

Cyrus is a charismatic figure who speaks and acts with a calm, logical demeanour. He detests human minds and emotions, finding them defective.

Team Galactic Commanders


Mars is a strong-willed commander who hates to lose and has sworn loyalty to Cyrus. Her passion for Pokémon sometimes inspires powerful emotional outbursts. Her partner Pokémon is Purugly.​


Jupiter has a mysterious air about her. She is undeniably skilled at Pokémon battles, but she’s willing to do anything—even steal other people’s Pokémon—to achieve her goals. Her partner Pokémon is Skuntank.​


Saturn is a cool and collected commander. Despite being one of the few who occasionally harbour doubts about Cyrus’s plans, Saturn is cold and dispassionate enough to carry out his orders faithfully. His partner Pokémon is Toxicroak.​

Legendary Pokémon

During your adventure, you’ll be able to encounter the Legendary Pokémon Dialga in Pokémon Brilliant Diamond or Palkia in Pokémon Shining Pearl.

Dialga and Palkia are Legendary Pokémon that appear in the myths of the Sinnoh region. It is said that Dialga is the master of time, while Palkia is the master of space. Both are known as deities to the people of Sinnoh.

How will these two Legendary Pokémon be involved in your story?

At a glance, this mysterious Pokémon statue in Eterna City looks a bit like Dialga and a bit like Palkia as well—but it’s unclear who created it, in which era, and for what purpose.


  • Dialga has the power to control time. It appears in Sinnoh myths as an ancient deity.
  • This Pokémon is spoken of in legend. It is said that time began moving when Dialga was born.


  • It has the ability to distort space. It is described as a deity in Sinnoh mythology.
  • It is said to live in a gap in the spatial dimension parallel to ours. Palkia appears in mythology.

Mount Coronet and the Spear Pillar

Mount Coronet towers over the center of the Sinnoh region, its peak always covered in snow. This huge mountain is sacred to the people of Sinnoh. A massive maze sprawls within it, but the deeper you go, the stronger the wild Pokémon you’ll encounter.

On the peak of Mount Coronet is the Spear Pillar, which appears to be the ruins of an ancient temple. No one knows if the people of old once used this place for their rituals, or if it was perhaps the dwelling of some sacred creature.

Legendary Pokémon Uxie, Mesprit, and Azelf​

These three Legendary Pokémon feature prominently in many of the Sinnoh region’s myths.

What role will Uxie, Mesprit, and Azelf play in your adventure?​

Uxie is called the Being of Knowledge.

    Mesprit is called the Being of Emotion.

      Azelf is called the Being of Willpower.

        Three lakes represent the Sinnoh region.​

        Sinnoh boasts three lakes filled with bountiful water: Lake Verity, Lake Valor, and Lake Acuity. According to regional myths, Legendary Pokémon slumber at the bottom of these lakes.​
