I got the Hasbro TR Overlord and like the other Titans Returns, he comes packaged in robot mode. The only bit to fully transform to robot mode is to flip the black piece that's behind his head down so that its flush against his back. So far have no luck as the hinge that should allow half of that black piece to flip down is stuck. Anyone ran into this and found a way to fix it? The part I'm trying to flip down is at the 14 minute mark in this video. Thanks.
