Treecko are small, bipedal, lizard-like Pokémon. They have two dark green, leaf-like tails, and a red underside, similar to its evolutions Grovyle, and Sceptile. Each of its hands and feet have three digits. It has bright yellow eyes and skinny reptilian pupils. The bottom of its feet are sticky, enabling them to cling to things.

Special Abilities

All Treecko, and all Grass-type starters, have the ability Overgrow, which allows it to use Grass-type moves at 150% if its HP is below 33%. In the Dream World, Treecko's ability Unburden doubles its speed in battle once it's held berry is consumed, assuming it is holding a berry. Tiny spikes located on each of Treecko's digits allows it to stick to and climb walls with ease.

Treecko first appeared in the episode Get the Show on the Road!, where it was introduced to May as one of the Starter Pokémon from Professor Birch.

In the episode Tree's a Crowd, Ash caught a Treecko which would later evolve twice into a Sceptile. It usually puts a twig in its mouth.


  • Treecko, Snivy and Chespin are the only Grass-type starter Pokémon not able to learn Razor Leaf.
  • It is one of the three Grass type starters to not walk on all fours, the others being Snivy and Chespin
  • Treecko is the only Grass-type starter that can climb trees.


Treecko's appearance is based heavily off of a gecko or lizard. More specifically, it is likely based on a leaf-tailed gecko.

Names In Other Languages

Its Japanese name, Kimori, comes from combining the words "ki" (tree) and "yamori" (gecko).
