The crowning moment for many Pokemon players is when they finally get the chance to catch the Legendary creatures that feature on the cover of the game's artwork. In the case of Brilliant Diamond and Shining Pearl, those Pokemon are Dialga and Palkia.
You'll have to go through the wringer to earn a chance at catching either one and we've to all the info you need to prepare to catch them.
Pre-Warning
You would be wise to turn off autosave and drop a save point right before you encounter Dialga or Palkia. If you were to defeat either of the Legendary beasts with autosave turned on, then you will have lost your only opportunity.
How to Get to Dialga or Palkia
To earn the chance to battle either of these Pokemon, you'll need to essentially beat the main game story in either Brilliant Diamond or Shining Pearl. Here's a rundown of the story points that you'll need to complete beforehand;
- Complete first seven gyms by defeating their leaders
- Reach and defeat Cyrus in Team Galactic's HQ
- Defeat Saturn and free the Lake Trio
- Defeat Mars & Jupiter at Mt. Coronet
- Once again, Defeat Cyrus
After you complete the above steps, you're presented with the chance to battle and catch Dialga in Brilliant Diamond or Palkia in Shining Pearl.

You can use your Master Ball to guarantee a catch here or save it for another time. If you choose to use an alternative method we would recommend Ultra Balls. It's not going to be easy so make sure you're well stocked up before taking on this battle.
