So they tooled up a new head, glasses, a mask, and some armor. Mattel has told us before that to get an entire figure out of just tooling a head, armor, and accessories was pretty do-able. That was sort of the guidelines for the 30th Anniversary Create-A-Figure Contest.
I assume the Four Horsemen sculpted ol' Stan's head, but I'm not 100% sure on that. Either way it looks great... but it's powder blue. I do think it's funny that his armor looks similar to the Marvel character Galactus.
Standor's Armor and Mask is made of a cool smoked clear plastic with glitter flakes in it.
