The first malady is the warped legs. Although the warping of the left leg seems to be the most obvious and intense.
The second irregularity is a little bit more difficult to see. The back of the “head” (essentially the rear topside of the figure) is indented.
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..
