From the anime and manga "Gundam Thunderbolt," the Psycho Zaku has been designed with heightened proportion and features by mechanical designer Hajime Katoki. Unique aspects to this Gundam MG 1/100 Psycho Zaku (Ver. Ka) model kit include giant special booster seen only in the animation, completely articulated sub-arms that can fold into backpack, realistic joint and power pipe covers, and sole mounted-claws.
