In the Sinnoh remakes, players can catch rare characters in Hideaways. Here is a list of every Pokemon that can be found in Pokemon Brilliant Diamond & Shining Pearl’s Grand Underground.

Pokemon Brilliant Diamond & Shining Pearl are largely faithful adaptations of the 2006 DS titles. A good example of this is the Pokedex as Studio ILCA chose to go with the original 151 Pokedex over the expanded Platinum edition.

However, BDSP actually allows Trainers to catch Platinum ‘mon early into the game with the new Hideaways feature. So those disappointed in not being able to get Houndoom, you are in luck as you can catch the Fire-type and many more. Here is a full list of every Grand Underground Pokemon.

Players can find rare Pokemon not in the Sinnoh Dex in the Grand Underground.

While the Sinnoh Underground was technically in the original Diamond & Pearl, Studio ILCA has gone to great lengths to massively overhaul it. So much so that players are able to score powerful Pokemon as early as Eterna City (which is towards the beginning of the game).

While exploring the underground caverns, players will stumble into mini terrarium-like rooms called Pokemon Hideaways that have a handful of species roaming around.

This changes after beating the story and unlocking the National Pokedex in the post-game. The list below is every ‘mon you can get before the Elite Four. Note: We are still discovering Underground Pokemon. We will update this as we find them.
