TMs teach a Pokémon a specific move once, while HMs can be taught and forgotten (with the Move Deleter) multiple times. HMs are essential for navigating the world (Cut, Fly, Surf, Strength, Flash, Rock Smash, Waterfall, Dive). TMs offer powerful battle moves. Many TMs are found throughout the world, purchased, or received as Gym Leader rewards. Use them wisely!
