The vast majority of collectors do not have the gross abnormalities of Manufacturing Error Figures in their collections nor have they ever seen one in person. However, the vast majority of collectors have come across figures with small problems – normally some type of warping: an oddly positioned foot, arms or legs too far apart or too close together, a small dent in the figure, or a pose that simply does not match identical sculpts.This warping is likely the result of the figures being removed from the molds too quickly. These warped figures were handled while they were too warm and had not properly cooled and been allowed to set. Figures with dents could also be the result of the cooling time being too short, but also as a result of the injection pressure being too low, excessive material, and/or several other possibilities.
This warping could be called, “The M.U.S.C.L.E. Warp.” Even Mattel was subject to having figures that were warped. For example, in a toy industry magazine two figures can be seen with significant warping in their heads.
Below are some more examples of Warped figures:
If you have M.U.S.C.L.E. figures with warping, dents, or other abnormalities, please email a short explanation and pictures to the University of M.U.S.C.L.E..
Figures with much more significant errors and abnormalities are highlighted in the section titled, Manufacturing Error Figures.
