Treecko doesn't appear in Scarlet & Violet. Transfer it from Ruby, Emerald, or Brilliant Diamond to add it to your collection. Check the source games below for encounter details.

Treecko is not available as a wild encounter in this game.

Also found in:

  • Treecko isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Grovyle to unlock its full potential. At 310 BST, it's a stepping stone rather than a team anchor.

  • Treecko's biggest threats include Charizard (Fire), Cloyster (Ice), and Crobat (Poison), all carrying super-effective STAB moves. Flying and Bug-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Treecko evolves into Grovyle at level 16. Treecko is the base form in a 3-stage evolutionary line.

  • Overgrow is the go-to ability for Treecko. It strengthens grass moves to inflict 1.5× damage at 1/3 max HP or less. Its hidden ability Unburden can work in specific setups.

  • Treecko fills the balanced role. It's a physical attacker with base 45 Attack. Base 70 Speed is workable — faster than some, slower than many. And it's fragile — can't afford to take many hits.

  • Treecko appears in 16 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.

Treecko first appeared in Ruby & Sapphire and has been available in 16 games across 7 generations. Obtainable through catching or hatching as a base form in most titles where it appears.
