Kakuna is an insect-like Pokémon with an appearance similar to that of a yellow chrysalis. As a chrysalis, the interior of Kakuna's very hard shell is unseen, with no limbs or other features being shown. Only Kakuna's eyes, jet black in color, are visible from the shell, which are somewhat large in proportion to its body. In Pokémon Red and Blue Versions, Kakuna had arm-like limbs, which were never seen afterwards.
As Kakuna are inside of a shell, they have little or no movement and almost no offensive capabilities. As a defensive measure, they can harden their shells against an attacker and may even be able to use Poison Sting.
In the anime
Kakuna have made various minor appearances throughout the series in a similar fashion to that of their debut appearance.
