FireRed & LeafGreen Treecko Best Moveset
Bulk and offense in one package. Treecko runs Leftovers for passive recovery each turn with a Jolly nature, so it survives long enough to threaten with Substitute. Max Sp. Def and Speed EVs and Normal coverage make it hard to safely switch into.

- Substitute
- Seismic Toss
- Endeavor
