Kakuna is Pokédex #014, generation 1 (Kanto). Kakuna is a Stage 1 Grass Pokémon with 80 HP. The card says it evolves from Weedle. In this catalog that name is Weedle (#013).
Kakuna sits at 2/86 in Chaos Rising, position 2 of 122. Before it is 1 Weedle, and after it is 3 Beedrill ex. The set belongs to the Mega Evolution series. It was released on May 22, 2026. The printed size is 86. This checklist is longer, at 122 cards. The listed rarity is Common.
Exoskeleton is listed as Ability. This Pokémon takes 20 less damage from attacks (after applying Weakness and Resistance). The attack Hang Down lists 20 damage. The cost is Grass.

Kakuna (#014) has 21 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 1999 to 2023. The earliest other card is Kakuna 33/102 in Base (1999). Both list 80 HP. The rarity there is Uncommon, and here it is Common. Keiji Kinebuchi illustrated that card, and Mugi Hamada illustrated this one. Retreat cost there is 2, and here it is 3. 6 other cards of Kakuna list a different HP.
The illustrator line reads Mugi Hamada. I count 6 other cards in the catalog with that illustrator.
Chaos Rising set binder is where a full Chaos Rising set goes. This card fills one slot there. A generation binder holds one card of each species. Kakuna can fill a slot in Generation 1 binder (Kanto). I still need this card.
