Every Pokémon Location in the Grand Underground in Brilliant Diamond and Shining Pearl

I didn't think so many Pokémon could exist here either.

The Grand Underground is a vast wild Pokémon area in Brilliant Diamond and Shining Pearl that lets you capture several Pokémon. Many Pokémon found in the Grand Underground are even rare ones you’d have difficulty searching for in the overworld.

The number of Pokémon you can encounter in the Grand Underground increase a total of five times:

  • When you receive TM96 Strength.
  • When you receive TM97 Defog.
  • When you beat Candice in Snowpoint City.
  • When you receive TM99 Waterfall.
  • When you’ve completed the National Pokédex.

Over 200 Pokémon should be discoverable in the Grand Underground at the last stage.

That said, here’s every Pokémon you can encounter in the Grand Underground, when can you encounter them, and where.

Pokémon encountered the moment you can enter the Grand Underground
