With the official unveiling of the MOTUC Skeletor, here's #2 of 4 of my cardback pitch.
To cover as much ground as I could with these illustrations, I was thinking that Mattel "may" opt for 2-packs. This is the reason you'll notice that all heroic characters face right and all the evil characters face left... it was a "just in case..." kind of thing.
Like Beast Man, I made a few final colour changes (as well as a few very small detail additions - ie. the shin guard buckles were added after seeing Mer-Man at SDCC.)
The only thing I didn't reference from the cardback art on him was his face - I just had this inkling to Alcala*-ize his face!
*Alfredo Alcala was the original artist of the old vintage mini-comics that came with the figures.
