This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular browser game "Kantai Collection -KanColle-" comes a Nendoroid of the second Shokaku-class aircraft carrier, Zuikaku! The Nendoroid is based on Zuikaku's "Kai Ni A" upgrade but also has parts to recreate her standard version. Nendoroid Zuikaku comes with three expressions including her standard expression, a half-damaged expression that doubles as an expression for combat scenes as well as a grumpy expression.
An alternate body to recreate her half-damaged appearance is also included, allowing fans to enjoy all sorts of different scenes. Other optional parts include a variety of aeroplanes to fly beside her such as a Type Zero Fighter Model 52, a Type Zero Fighter Model 62 (Fighter-bomber), a Zero Fighter Model 52C (Iwai Platoon) and a Suisei bomber. She also comes with some ice-cream just like her sister ship, Shokaku.
Note: Nendoroid Shokaku will be available for preorder at the same time as Nendoroid Zuikaku, and preordering both of them together will include both a "Holding Hands" part as well as a "Fleet Formation Base Attachment" as a bonus! The Fleet Formation Base Attachment allows you to pose the Nendoroids at different heights making them appear in a formation in your display!
