Kakuna sits in the middle of its evolution line — stronger than Weedle but not yet at full power. Most trainers push through to Beedrill as fast as possible. Known as the Cocoon Pokemon. Part of the Gen 1 roster.
You won't find a real weakness in Kakuna's stat line. It's well-rounded for the Cocoon Pokemon, and what it does with that depends on moveset and items. Yields 2 Defense EVs, on a medium-fast 1M XP curve.
Almost incapable of moving, this POKéMON can only harden its shell to protect itself from predators.
Kakuna Weakness
FragileType-wise, Kakuna takes extra damage from Fire, Flying, Psychic, Bug, and Rock. Kakuna's physical bulk (base 50 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
This Bug/Poison-type links Weedle to Beedrill. Kakuna has 205 stats but sits in the Undiscovered egg group. Defense has grown the most so far (+20), but there's still another 190 stats to gain in the final evolution.
How to Evolve
Best Build
Gen 1 build content has limited support (no abilities, held items, or natures).
Try selecting a different game/generation filter, or check back later.
A compact toolkit overall. The offense runs through Poison Sting for Kakuna, with limited coverage doing what it can. Don't expect versatility from this one.

At 205 BST, Kakuna is firmly in pre-evolution territory. Evolve it into Beedrill before bringing it to any serious fight.
Kakuna's biggest threats include Charizard (Fire), Aerodactyl (Flying), and Alakazam (Psychic), all carrying super-effective STAB moves. Bug and Rock-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 35 Speed, Kakuna won't outrun any of these threats so switching to a resist is usually the safer play.
Kakuna is leaning toward the physical side (base 25 Attack). Fragile — can't afford to take many hits, too. But the speed tells the real story — base 35 Speed is low. Priority moves or Trick Room are the way to go.
