Clawful and Whiplash I doubt, they'd need too much new tooling. It would be great because parts for characters like Buzz-Off, but Hordak just ate some tooling budget along with She-Ra.
Webstor(who is my favorite character and I'd kill for a Mega figure) and Ninjor both only require a new head and armor piece. Both just use the Skeletor body, and we have the mold for Webstors gun, grab Ninjors accessories from TMNT. Pretty simple.
That said, my fear is what we will see with Snake Mountain are just variants of the big 5, Skeletor, Beast Man, Mer-Man, Tri-Klops, and Trap Jaw. Then round it out with a He-Man, there's your 6 allocated minis. It just seems like an easy out that they might take. Really hoping for Webstor or one other unique character.
