Certain techniques called Hidden Machines (HMs) can be used outside of battle, and these are usually only earned after beating a town’s Gym Leader. How to get each of them is discussed within the walkthrough of this guide. HMs can be taught to different Pokemon as many times as you want, provided that those Pokemon are capable of learning them. Learning HMs will give you and your Pokemon access to parts of the map you have not yet visited. For instance, learning Surf will allow your Pokemon to travel across the seas and discover faraway island locations, which are necessary to your quest.
These HMs can be found and learned during the course of the game:
| HM | Ability |
| 01 | Cut |
| 02 | Fly |
| 03 | Surf |
| 04 | Strength |
| 05 | Flash |
| 06 | Rock Smash |
| 07 | Waterfall |
| 08 | Dive |
