Laser Light. The original is very odd looking (and even squattier than other versions - looks like he's about to take a steamy one in the woods), but I'd really like to see the 4H take on him. The original sculpt isn't that great, but the overall design is interesting.
TerrorBras Skeletor isn't all that interesting. In fact they could just include the bra and claws as accessories with Laser Light, and people could use them on the standard Skeletor if they wanted to.
