I decided to just get Mumm-Ra and Lion-O from the crossover as they were the two I had when I was little and I was annoyed even back then that they didn't fit well with my He-man stuff. As I noted above, my Super7 Mummy Mumm-Ra also fits great with these. One weird note, though, if you use Cartoon Man-E-Faces poorly documented head-swapping with Skel-Ra's face, you get Nightmare Fuel. I am still considering the TC He-Man as a King Grayskull sub.
