Treecko has only gone further downhill since DPP. This unfortunate little gecko struggles to adapt against new threats such as Ferroseed and Larvesta as well as old enemies such as Houndour and Bronzor. Yet, with a passable base 70 Speed and base 65 Special Attack, Treecko stands out as one of the few attacking Grass-types in Little Cup that does not rely on the weather. Overall, Treecko might not always be the best choice for a team, but it's definitely worth considering for originality or to fulfill a particular niche.

Attacking Lead

Eviolite / Focus Sash Overgrow Hasty / Naive
Moveset EVs
~ Leaf Storm
~ Hidden Power Fire
~ Giga Drain
~ Quick Attack
36 HP / 240 SpA / 200 Spe

Treecko's attacking lead set from DPP is still perfectly capable of functioning in the BW metagame. Leaf Storm is Treecko's most powerful STAB move and hits common leads such as Hippopotas very hard. Hidden Power Fire provides excellent additional coverage, smacking Grass- and Steel-types switching in to soak up Leaf Storm, such as Snover, Ferroseed, and Bronzor. Giga Drain serves as an alternative STAB that also provides recovery in a pinch. Quick Attack is used in the last slot to finish off weakened enemies and frail sweepers such as Wingull.

Swords Dance

Life Orb / Eviolite Overgrow Naive / Jolly
Moveset IVs
~ Swords Dance
~ Bullet Seed
~ Drain Punch
~ Rock Slide / Hidden Power Ice
3 HP
236 Atk / 200 Spe

Though Treecko has a higher Special Attack stat, access to Swords Dance and a better physical movepool make it a decent physical sweeper. Bullet Seed and Drain Punch both became more powerful this generation, allowing Treecko to use them more effectively. Bullet Seed is Treecko's best physical STAB move, and the fact that it breaks through Substitutes means that users of the move will be unable to effectively check Treecko. Drain Punch replaces Giga Drain as a source of recovery while still hitting most Steel-types hard. Rock Slide is the preferred option for superior coverage, but Hidden Power Ice can be used to hit Dragon-types and opposing Grass-types harder.

Other Options

Choice items might seem like a good idea, but they are not recommended due to Treecko's average attacking stats. Crunch and Pursuit hit Ghost- and Psychic-types, but they offer inferior coverage to Treecko's other moves. Treecko also has access to Leech Seed and Synthesis, but its frailty prevents it from being able to use them effectively. Energy Ball is an excellent STAB move, but Giga Drain is superior because it provides recovery. Brick Break is another good option, but like Energy Ball, it is outclassed by a recovery move. GrassWhistle would be a good alternative on the Lead set if it weren't for its poor accuracy. Lastly, Treecko has Agility, which could work on its own set had Treecko been blessed with higher offenses.

Checks and Counters

Like many fast sweepers, Treecko hates priority users; Croagunk in particular resists most of its attacks on both sets. Treecko is also easily revenge killed by Choice Scarf users such as Houndour and Chinchou. Litwick is problematic for both sets as it can take all of Treecko's attacks bar Rock Slide and the rarely seen Crunch and OHKO with a STAB Fire Blast. Bulky Poison-types such as Skorupi can come in on Bullet Seed and Drain Punch and strike down Treecko with a STAB attack. Ferroseed and Bronzor take even a Drain Punch comfortably and threaten a KO with Gyro Ball or, in Bronzor's case, Hidden Power Ice.


Treecko's Dream World ability is Unburden, which doubles its Speed if its item is used up or removed. This ability would be more useful than Overgrow for Treecko, but unfortunately, it only comes on a Level 10 male Treecko, making it illegal in Little Cup.
