## TMs & HMs

Generation III has **50 TMs and up to 8 HMs** — Ruby, Sapphire, and Emerald have all eight, while FireRed and LeafGreen have seven (there's no HM08 Dive in Kanto). The crucial thing to remember: **TMs are single-use.** Teaching a TM move consumes the disc, so each copy you own can be used exactly once — unlike later generations where TMs are reusable. HMs, by contrast, can be taught as many times as you like and double as field moves (Cut, Fly, Surf, Strength, Flash, Rock Smash, Waterfall, Dive).

TMs reach you several ways: handed out by **Gym Leaders** when you beat them, found as items in the overworld, given by NPCs for completing tasks, and bought. The **Celadon Department Store** (FireRed/LeafGreen) and **Lilycove Department Store** (Hoenn) sell a selection, and the **Game Corner** prize counters trade big coin totals for powerful TMs like the elemental beams.

Because a TM vanishes after one use, decide carefully who learns it — and check what each Pokémon can already learn for free by level-up before spending an irreplaceable disc.
