>In Omega Alpha Adventure 10, it was explained that TMs are machines that contain the essence of the move they teach to a Pokémon. Before this technology existed, other items served the same purpose. Such items are the rings Ultima carries on her staff, which contain the ultimate moves Frenzy Plant, Blast Burn, and Hydro Cannon, and a scroll held by the Draconids, which contains the move Dragon Ascent.Personally though, I just do what the anime does and pretend that TMs don't exist, and just have Pokemon learn everything naturally, or by training.
