Skeletor confused me as a character growing up. You have this massive bulk body and then the head of a talking skull. To me, there was no real way to translate that in real life. As with Evil Lynn in this series, I re-imagined the characters.
In the case of Skeletor living in Snake Mountain, I envisioned more of a tribal route with him. Researching tribal body painting and shaman images, I felt there was a happy medium to merge that with the iconic dudes in underwear image that the cartoon instilled into 1980's children's memories with a real world application of dark magic.
