Here's my NDR/MH hybrid next to one of my Gohs:
I just remembered I have an EB-N as well. Give me a minute and I'll take a shot of the three of them together. And let me know if there're any other comparisons you'd like to see. It's too dark for skin tone comparisons right now, but maybe tomorrow.
As for skin colors that match MH, so far there are only three MH boys that have "normal" skin colors (ie: not blue or purple)...
-Jackson Jekyll will match Obitsu/Volks 'normal' (as I said previously) as well as NDR 'pale' (though NDR heads are somewhat rare now-a-days) The Gloom Beach version of Jackson does not have jointed wrists.
-Deuce Gorgon is a darker, peachier caucasian color that I didn't think had any matches, but I just held my "guy" colored Goh head up to his chest and it looks like that could be a close match. The downside is I don't think Mattel has released a jointed-wrists Deuce yet, which is a huge turn off for me. Hopefully soon, though?
-Clawd Wolf I don't have, but he looks to be much darker than Obitsu's Maroone or Coconut skin colors. He seems more "Generic Mattel AA" colored, which is definitely good news for a bunch of characters I want to make, though that means dying or thoroughly blushing a head to match. So far only the "Sweet 1600" version of Clawd has jointed wrists.
