This is a posable action figure of a character from science-fiction/anime.
Here's another fantastic Kamen Rider action figure release by Ohtsuka Kikaku: Kamen Rider Kuuga in Amazing Mighty form! Included in this set are armor parts and henshin belt (all made of PVC) for Amazing Mighty form and a polyurethane body suit that can be put on the articulated die-cast metal body frame to display Kamen Rider Kuuga in Amazing Mighty form. Extremely posable!
