Without Tinted Lens, Butterfree wouldn't see any competitive play. With it? It makes resisted hits deal full damage, turning modest base stats into a real offensive threat. Bug/Flying is solid coverage on top of that. It needs some investment to avoid getting outsped.

Butterfree's spread isn't flashy. Sp. Atk leads, Attack trails, 2 stats clear the bar. Tough to catch and worth 3 Sp. Atk and Sp. Def EVs, on a medium-fast 1M XP curve.

Butterfree Weakness

Vulnerable

Butterfree is weak to Rock, Fire, Electric, Ice, and Flying-type moves. Watch out for Rock attacks, those deal 4x damage. On the flip side, it's immune to Ground-type moves entirely. Butterfree's special bulk (base 80 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.

Butterfree is the final form in a three-stage chain from Caterpie through Metapod. Breeding this form produces Caterpie eggs (quick to hatch). Evolving from Caterpie gave Butterfree the biggest boost in Sp.Atk (+70), bringing the total to 395 stats.

Prediction matters here. Choice Scarf means Butterfree can't change moves after clicking, but the payoff is speed patching through item lock. Max HP and Speed EVs with Compoundeyes back that up. Utility options prevents free switches.

TMs define Butterfree's movepool. The natural moves cover basics with Bug Buzz and Air Slash, but the real versatility comes from technical machines giving it Psychic and Normal coverage and more. That's where the options open up.

    or evolve from Metapod (Step 2)
  • Don't let Butterfree's 395 base stat total fool you. Tinted Lens is what makes it tick — it punches way above its weight class. We rate it C-Tier.

  • Butterfree's biggest threats include Golem (Rock), Charizard (Fire), and Raikou (Electric), all carrying super-effective STAB moves. Golem is the most dangerous since Rock moves deal 4x damage. Ice and Flying-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Metapod evolves into Butterfree at level 10. Butterfree is the final evolution in a 3-stage line starting from Caterpie.

  • Run Tinted Lens on Butterfree. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Butterfree also gets Compound Eyes, but they don't compare.

  • Butterfree fills the balanced role. It's a special attacker with base 90 Sp. Atk. Base 70 Speed is workable — faster than some, slower than many.

  • Butterfree appears in 19 games, including Yellow, Red & Blue, and Gold & Silver.

Butterfree first appeared in Red & Blue and spans 19 games across 9 generations. It later gained a Gigantamax form in Generation 8, adding new dimensions to its competitive identity.
