Kakuna Weakness
Type-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.
| Damage | Types |
|---|---|
| 2x (Weak) | Fire, Flying, Psychic, Bug, Rock |
| 0.25x (Resist) | Grass, Fighting |
- 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

Kakuna Red & Blue Guide
In Red & Blue, for a casual playthrough, Kakuna works as a placeholder. Bug/Poison coverage is useful early. The real payoff is Beedrill. That's where the stats start mattering.
