In all Main-line Pokémon games, the fun doesn’t stop once you’ve defeated the Elite Four. There’s always plenty of post-game content to help you squeeze even more playtime out of the game. Brilliant Diamond and Shining Pearl are no exception.

In this Post-Game Guide, we hope to point you in the right direction for all the best things to do once you’ve finally taken down Cynthia and her Garchomp.

Get the National Pokédex and the Poké Radar

Before you can do any of the fun post-game activities in Pokémon BDSP, you’re going to be repeatedly told to finish your Pokédex and hand in the report to Professor Rowan.

You’ll be pleased to know that this doesn’t mean you have to capture all 151 of the Sinnoh Dex’s Pokémon, but you will need to see them all at least once.

By simply playing through the game and defeating the Elite Four, you will probably have seen a vast majority of them, but there are a few that are quite easy to miss…

Sinnoh Pokédex Missable Pokémon

Route 212

One part of Sinnoh that players often overlook is Route 212, between Hearthome and Pastoria. This is because there’s no real need to go there as part of the story.

Because of this, you may miss opportunities to add certain Pokémon to the Sinnoh Dex, such as #102 Chatot, which is only owned by a single trainer who can be found here; Gentleman Jerry.

If you chose Turtwig as a starter you will also want to find Ranger Jeremy on Route 212, who is the only trainer with a #008 Prinplup.


Another easy-to-miss Pokémon is #65 Drifloon. After you have saved the Valley Windworks from Team Galactic Drifloon will return to the area, but only on a Friday.

Go to the Valley Windworks on a Friday (or change the date on your switch to Friday) and you will find one waiting for you right outside the front door!


Another easily missed Pokémon is #115 Riolu. If you don’t want to hatch the Riolu Egg, you will need to find Veteran Grant on the lower floor of Oreburgh Gate, who is the only trainer with a Riolu. You are going to need HM Rock Smash and HM Surf to reach him.


Players are also likely to overlook #114 Unown as there are zero trainers with an Unown in all of Sinnoh. To find one, you will need to head to the ruins on the east side of Solaceon Town and run around in there until you encounter one.

Mesprit, Azelf and Uxie

Now that you have freed Mesprit, Azelf, and Uxie from Team Galactic, you can revisit Lake Verity, Lake Valor, and Lake Acuity to encounter each of them individually.

You will get to fight Uxie and Azelf when you interact with them, adding them to the Pokédex and giving you an opportunity to catch them.

Mesprit, however, will flee when you interact with it, making you chase it across Sinnoh for a chance of catching it.

Not to worry, though, as it will be added to your Pokédex just before it runs away.

Dialga and Palkia

And what about the Legendary Pokémon Dialga and Palkia? You can only get one per game, so how are you to see the other?

Well, if you go back to Celestic Town after defeating Cynthia and speak to her Grandmother, she will show you a picture of whichever legendary you cannot acquire in your game, which is enough to add it to your Pokédex!

Of course, you could always trade or battle with a player who has the other version.


It’s helpful also to note that you do not need to add #151 Manaphy to your Pokédex. Just having the first 150 Sinnoh Dex Pokémon is enough to satisfy Prof. Rowan.

However, if you do want a Manaphy anyway, use the “Mystery Gift” option in the pause menu to get a Manaphy Egg via the internet.

How to Get the National Dex

Once you have filled your Sinnoh Dex with all 150 Sinnoh Pokémon, fly to Sandgem Town and speak to Professor Rowan in his lab. He will thank you for your efforts and then you’ll get a surprise visit from Professor Oak.

He’ll mention something about Ramanas Park being open now, and will update your Pokédex to now include the National Dex feature.

With this, you will now have access to a whole array of new post-game content!

After Oak leaves, Rowan will give you an extra little surprise; the Pokéradar.

About the Pokéradar

The Pokéradar is a new Key Item that you can register from your bag to the button. It can be activated while you are standing anywhere that a Pokémon can spawn; i.e. Tall Grass, Caves, Water.

When you activate it, you will see particles jumping up from tiles where there is currently a Pokémon. Walking over those tiles will start an encounter immediately.

After you complete that encounter, a chain will start and there will be more particles nearby. Walk into another patch of particles to start another encounter.

The more encounters you chain together in this way, the more likely it is that you will encounter a Pokémon with rare stats or “shiny” colors.

There is normally a 1/4069 chance of finding a Shiny Pokémon, but you can reduce this to as low as 1/99 by chaining together 40 or more Pokéradar encounters.

After using the Pokéradar, you will need to recharge it before you can use it again. It charges with each step that you take.

Pokéradar-exclusive Pokémon

As an additional bonus, there are some wild Pokémon that you can only encounter by using the Pokéradar…

Get a Free Eevee

Once you have got the National Dex, you will be able to get an Eevee completely free from Bebe in Hearthome.

Check out our Guide on Where to Get Eevee and how to evolve it!

Catch Rotom

After acquiring the National Dex, you can find and capture Rotom in the Old Chateau at the north end of Eterna Forest at night.

See our full guide for How to Get Rotom and how to change its form!

Catch Cresselia

If you have the National Dex, you can find and interact with Cresselia on Fullmoon Island. Once you have interacted with it, it will roam Sinnoh in the same way as Mesprit. If you can find it in the wild, you will get a chance to capture it.

See our full guide on Where to Find Cresselia and the best ways to hunt it down!

Catch Giratina

After getting the National Dex, you will be able to enter a new area on Route 214, which leads to Turnback Cave. This randomly-generated labyrinth contains the Legendary Pokémon Giratina.

See our full guide on Where to Find Giratina and how to navigate Turnback Cave.

Explore the Battle Zone and Catch Heatran

Once you have the National Dex, you will be able to partake in some extra post-game story content on Battle Zone Island.

The island is covered in tough trainers who are eager to battle you, making this a great place to toughen up your team if you hope to rematch the Gym Leaders.

After concluding the post-game story in Stark Mountain with an NPC named “Buck”, you will be able to find and catch one of Pokémon’s most forgettable legendaries – Heatran, inside Stark Mountain.

View our full guide on Where to Find Heatran and the steps required to access it.

Find Rare Pokemon via Swarms

If you have the National Dex, you can speak to Dawn/Lucas’ sister in the house southeast of the Pokémon Lab at Sandgem Town and find out about Pokémon Swarms!

The first time you speak to her she will tell you that she’s been hearing about Pokémon Outbreaks on the News. Speak to her a second time and she will give you specific details.

Once you have this info, you can refer back to it at any time via the pause menu.

Head to the location in question and you will see what she’s talking about. The Pokémon will be clearly visible in the area, rather than hiding in tall grass. Simply walk up to any of them to initiate a fight.

The Outbreaks change every day so check back frequently to find more rare Pokémon!

Visit Ramanas Park

When you hand in your Sinnoh Dex to receive the National Dex, Professor Oak appears and mentions something about Ramanas Park opening. You can find Ramanas Park at the east end of Route 221, south of Sandgem Town.

In Ramanas Park, you can capture many other Legendary Pokémon from Johto, Kanto, Hoenn, and Sinnoh.

Check out our guide on How to Access Ramanas Park and each of the legendary Pokémon you can find there.

Catch Regigigas

Once you have defeated the Elite Four, you will be allowed to enter Snowpoint Temple, at the north end of Snowpoint City.

On the bottom floor of this temple, you will find a huge Regigigas statue which unfortunately doesn’t do anything. To activate it and fight Regigigas, you will first need to capture all three Regi-legendaries (Regirock, Regiice, and Registeel) in Ramanas Park.

Once you have done that, interact with the Regigigas statue with all three Regi-legendaries in your party and the Regigigas encounter will begin, giving you an opportunity to capture it for yourself!

Challenge All Gym Leaders Again

Once you have the National Dex you will be able to challenge all 8 gym leaders again.

They will have Pokémon at around Level 65-75 and their teams will feature Pokémon from all over Johto, Kanto, Hoenn, and Sinnoh.

This is a great way to gain exp for your Pokémon and is just a fun challenge in general.

You can also fight the Elite Four again whenever you like. They, too, will have more powerful Pokémon and updated teams, offering a whole new challenge for you to sink your teeth into.

It is helpful to note that if you defeat any Legendary Pokémon by accident, you can make them respawn by defeating the Elite Four again!

Take on the Battle Tower

On Battle Zone Island, you will find Battle Tower. Here, you can take on opponents in back-to-back battles until you’re eventually defeated.

With each trainer you defeat, you will receive Battle Points which can be spent on rewards from the Exchange Service Corner. Here, you can buy items, TMs, and even Mints that change the nature of your Pokémon!
