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.
KAKUNA remains virtually immobile as it clings to a tree. However, on the inside, it is extremely busy as it prepares for its coming evolution. This is evident from how hot the shell becomes to the touch.
Kakuna Weakness
AvgType-wise, Kakuna takes extra damage from Fire, Flying, Psychic, and Rock. The Bug/Poison typing picks up 4 resistances to work with. Kakuna's physical bulk (base 50 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
Kakuna sits between Weedle and Beedrill in this three-stage line. Not the final form yet. For breeding, quick to hatch with a decent partner pool via one 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
Breed with Kakuna to get Weedle eggs easily using 37 partners from the Bug egg group.

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. Rock-type attackers are also a problem. At base 35 Speed, Kakuna won't outrun any of these threats so switching to a resist is usually the safer play.
Shed Skin is the go-to ability for Kakuna. It has a 33% chance of curing any major status ailment after each turn. It's Kakuna's only ability.
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.
