This is a posable action figure.
From the GoodSmile website:
From the 2014 "Teenage Mutant Ninja Turtles" movie comes a figure of Leonardo!
From the 2014 "Teenage Mutant Ninja Turtles" movie comes a fully articulated series of figures! The figures have been very intricately sculpted and painted, creating a very faithful appearance that captures things such as the texture of their skin and shells, and even shows some of the damage they have taken in their many battles. Their facial expressions and equipment have also been carefully made to look exactly as they did in the films. The figures feature over 25 points of articulation. and the neck and elbow joints make use of flexible PVC for easy, natural-looking poses that still look great. Three sets of hand parts are included.
Leonardo is the leader of the team, with his blue mask and dual-wielded swords as his trademark weapon. His calm and collected appearance has been well-preserved in the figure which stands approximately 326mm in height. His swords are of course included to recreate all sorts of scenes from the film.
