This is a posable action figure of a character from science-fiction/anime.
From the Good Smile Company website:
From HALO Reach comes an articulated figure of Emile, the merciless warrior. He may have a bit of a vulgar personality, but he is respected by his peers and known to be a powerful fighter. His trademark skull helmet and the kurki knife on his right shoulder have been faithfully preserved on the figure, and threeA's unique weathered paintwork shows the harsh reality of the battlefield.
Painted 1/6th scale ABS & PVC articulated figure. Approximately 350mm in height.
