Legendary Pokémon from previous generations are available in Brilliant Diamond and Shining Pearl, with most able to be obtained in just one version of the game.
In order to find them, you'll need to head to Ramanas Park. However, there are a few prerequisites:
Which Slate do you need to find Raikou?
Ramanas Park is a vast area made up of several caves, in which a specific type of Slate is requested.
In order to unlock the three Legendary Beasts, take the Johto Slate to the Johto Room and place it on the plinth.
Save your game before placing the Slate if you're looking for a specific Beast -- if the one you want doesn't appear, just reload your game and try again. This will save you valuable time hunting Mysterious Shards, which are quite rare.
Meet Raikou, the Electric Beast
Capturing Raikou can be challenging. Here's what you need to know about the Thunder Pokémon.
Shiny Raikou
Raikou's shiny version is quite similar to the base form, being a darker shade of orange. Be mindful if you choose to knock out or flee when looking for another of the Legendary Beasts.
Tips to make it easier to capture Raikou
Follow this advice to make catching Raikou easier:
- Use a Quick Ball at the very start of the encounter, and a Timer Ball if the battle lasts more than 10 rounds.
- Take a Pokémon with False Swipe to ensure you don't accidentally kill it.
- Take a Pokémon that can inflict Paralyze or Sleep.
- Pay attention to how much PP its moves have.
- Save your game right in front of it, before engaging.
Absol is a good option for catching Raikou, especially if it can learn Thunder Wave.
If you accidentally knock it out, you will need more Johto Slates. Once you have captured it, you will not be able to re-summon it.
Additionally, upon exiting, an NPC will give you a Raikou Statue for your Secret Base.
