>>11115519Also this Monoshaft system was where the "Revoltechs can't stand straight or take neutral pose" idea comes from. Yamaguchi engineered these figures to take action poses and because the angled swivels of the Monoshaft is very limited in the direction and position they can be in compared to normal joints, they are in fact not capable to stand upright, arms and legs closed together. Until Revoltechs had all the moving parts connected by Revolver Joints only and even then it might be difficult depending on the sculpt.
AY Venom and Magneto had Monoshaft hips FYI.
