>>10137668the new HGUC has crazy chest articulation that no other Zaku has, which allows it to pull off dynamic poses (particularly with the bazooka) more fluidly than any other Zaku. the red sides of the chest have movement in two axes of rotation, independent of each other. also substantially more shoulder and elbow articulation than any other kit. the wrists/forearms are a bit odd until you realize they only want to sit in two positions 180 degrees relative to the other.
