This is a posable action figure from the Figuarts series.
As usual, this offering from Bandai's S.H. Figurarts series is all you could possibly ask for in a compact, posable figure of your favorite heroes. This time, it's Kamen Rider Den-O in his climax form. Of course there are plenty of option parts to give you dozens of different ways to portray the figure, including three sets of hands, two versions of his sword, and parts to replicate the "axe form," "rod form" and "gun form," and they can be attached to either his leg or arm to duplicate various killing attacks from the show. The number of permutations here is amazing. Highly recommended.
