Hidden Moves help trainers on their journey throughout Pokemon Brilliant Diamond and Shining Pearl.The system works much differently in these games than in past Pokemon entries. Trainers don't need to teach an HM to their partners to access it. Instead, Hidden Moves are loaded into the Poketch and call upon wild creatures.Overall, there are eight Hidden Moves in Pokemon Brilliant Diamond and Shining Pearl. They are obtained at different points through the story and require a specific Gym Leader to be defeated.How to gain access to each Hidden Move in Pokemon BDSPYou will either find Hidden Moves as TMs, that can be taught to your Pokemon or be given them from non-playable characters. These add them to your Poketch but don't allow you to use them just yet.SnorlaxMonster@SnorlaxMonsterI can't believe ILCA recognized that requiring you to teach HMs to Pokémon to use as field moves was a bad idea, but thought leaving Flash out of the Hidden Moves app and still requiring you to teach it to a Pokémon was fine #PokemonShiningPearl #NintendoSwitch8:15 AM · Dec 4, 2021111I can't believe ILCA recognized that requiring you to teach HMs to Pokémon to use as field moves was a bad idea, but thought leaving Flash out of the Hidden Moves app and still requiring you to teach it to a Pokémon was fine #PokemonShiningPearl #NintendoSwitch https://t.co/tVQGS1oF8uTo use them outside of battle via the Poketch Hidden Move app, you'll need to start beating the Gym Leaders of Pokemon Brilliant Diamond and Shining Pearl.

It used to be you had Technical Machines (TM) and Hidden Machines (HM). Both were moves you taught your Pokémon, but HM's were utility moves.
