How I can do this?

Super cheese sandwich

There is any skin or program? I want to replicate a body being taken by a demon. It's possible to do with Daz?

 

Thanks!

I assume the Spiderman/Venom images you attached are more or less what you are going for look-wise?

For the whole body one I don't know, but for just a hand maybe a rubber or latex-like shader on part of a geometry shell?  The little tendrils pieces flying off, I'd do post-work myself (or in Carrara maybe you could do it with metaballs) but if you really want to do those tendrils in-scene in Daz Studio maybe you could kitbash it from something like http://www.daz3d.com/liquid-pack depending on how comfortable you are in a modeling program.

2 figures, identical poses, demon one slightly larger...render both identically

take both to PS layer and go nuts with brushes of your choice

now, animated...that is way out of my league

Doing it in 3D will take some time and knowledge.  Doing it in postwork could be the same, so it really depends on your skill level.

For postwork:  You would likely be able to do renders that could be compositied and enhanced in an image editor.  You could do one with clothing, one without, so where you shred the clothing with brushes or drawing, you have skin beneath it to reveal.

Using brushes like these http://www.daz3d.com/rons-stain-splatter-drips-wash can help you get that drippy look.  The key is to do them and warp them (in Photoshop, I use puppet warp and/or liquify) to make the drips conform to the curvature of the area you are resting the drips on; otherwise it looks like you simply overlaid an image of drips over a render.

Liquify will definitely assist you in producing some of the look in the first image.
