Kakuna

Kakuna is a Bug/Poison-type Pokémon from the Generation I games. It is the first evolution of Weedle, who can evolve into Kakuna starting at level 7. Kakuna itself can evolve into Beedrill starting at level 10. They resemble a yellow chrysalis, and within their shell, Kakuna's large, black eyes are the only visible part of its body. Kakuna is one of several Pokémon to not appear in Pokémon Sword and Shield.

Because Kakuna are cocoons, their movement and therefore their moveset is limited. The main move that Kakunas can use is Harden, which increases its Defense. If evolved from a Weedle, Kakuna can inherit some of its moves, including Poison Sting. Kakuna has Shed Skin as its ability, giving it 1/3 of a chance each turn to recover from any possible status effects.

Kakuna falls under the Cocoon Pokémon category, as well as Metapod, Silcoon, and Cascoon. Aside from being cocoons, a consistency between all four is that as Wild Pokémon they can only use Harden.

In the Pokémon anime, Kakuna made its debut in "Challenge of the Samurai".

Leveling
The learnset is the same throughout Generation I to Generation VII.

Etymology
Kakuna's English and Japanese names are based on the word "," although the English word acts more as a misspelling.
