The NBK knock-off of the Generation Toy Gravity Builder member Crane hook, also known as, the Transformers Constructicon Hook is maybe the most stylized out of the entire group. He is a good toy, but really deviates from the more traditional character model. In upper torso mode for Devastator, he might be too aesthetically stylized for some people's tastes but has a really interesting conversion method, especially for making the combiners head!
