Next in the HGUC line is the weirdly proportion mass production Barzam from Mobile Suit Zeta Gundam. Even though it’s oddly shaped, it’s actually designed by the famous Mamoru Nagano. There is a Refined Barzam design that was done by Hajime Katoki for Gundam Sentinel that brought the design more in-line with the Gundam Mk. II. Hopefully they will release that design too.
Pictures show that this kit will have quite extensive poseability in the arms which bodes well for future releases. It’s coming in in May for 1,620 JPY. More pictures on Hobby Search.
