This page explains the purpose of the Hidden Moves (HMs) and where to find them.

Back in the days of Pokémon Red and Blue, Hidden Machines were items that can directly teach certain moves to Pokémon that can learn them, similar to Technical Machines (TMs). Unlike TMs, HMs can be used infinitely; also, the moves taught via HMs can be used outside of battle, to get past obstacles etc.

The last time HMs appeared was during the generation of Pokémon X and Y. If you’ve played the earlier Pokémon games, you may remember that HMs were rather cumbersome, often wasting valuable space in a Pokémon’s moveset. Or in the extreme case of the original Diamond and Pearl, encouraging you to drag a Bidoof or Bibarel with you…

Since Brilliant Diamond and Shining Pearl is a remake of one of these earlier games, HMs have returned. Although thankfully you no longer need to drag a Bidoof or other HM slave with you!

How to Use Hidden Moves¶

After obtaining a HM, it will be automatically be registered to the Hidden Moves app in your Pokétch. While this app is open, you can freely use any of the registered HMs by selecting them. A wild Pokémon will then come and use the HM for you.

To save time, you can also press the A button to inspect the obstacle etc. where you can use a Hidden Move, to use the Hidden Move there and then.
