TM048 (Japanese: わざマシン048Move Machine 048), known as TM48 prior to Generation IX, is a TM introduced in Generation I. It teaches a compatible Pokémon a move. The move it teaches depends on the game. For compatibility, refer to the move's page.
TMs in the Mystery Dungeon series are named only by the move they teach. For example, Attract is the item that teaches the move Attract. Most TMs, however, correspond to a TM in the core series' contemporaneous games.
In Rescue Team DX, TMs can only be used once. Whilst the available TMs are the same as those in Pokémon Sun and Moon, the TM list order is the same as for Super Mystery Dungeon (that is, in the TM order for Pokémon Omega Ruby and Alpha Sapphire), with newly added TMs added to the end of the list.
