When Oskarsson had a big sale at the DAZ Store, I picked up a Genesis 3 starting-point for making Thing from The Fantastic Four.
He’s HD though, so expect heavy render times in 3Delight. Fine in iRay, though those without workstations may want to lower the HD figure SubDivision levels down to 2 in both instances.
In Shaping, adding 45% ‘Barbaric’ give you the extra body bulk, then ‘HFS Brows’ gets you a bit nearer the Kirby uni-brow, etc.
You of course make your own orange version of the texture and could optionally ‘ink in’ the crack lines. Adding ‘Superhero Underpants’ gets the basic clothing look (though I think longer ‘swimming trunks’ is the current look). Still not great, even then (see below) but it provides a starting point that’s better than any other I’ve seen. The legs and feet need more work and widening, the mouth needs to be wider and the chin rounder, and Thing only has three thick fingers and a thumb.
Update: HFS Fantasy Shapes – ‘Hands: Beast’ are also useful morphs for getting more over-sized hands. Similarly for feet. Regrettably there is no three-finger morph for Genesis 3, though there is said to be one in HFS Ultimate Shapes for G8. Shrinking the little-finger down, pinky by pinky (there are three sections) to almost nothing, is a basic substitute but not ideal. It would require some Photoshopping later.
Update: JoeQuick had a Thing morph and MAT for Freak 4.
