Marvel has always been notoriously inconsistent about how Doom looked without his mask. One would hope that after Secret Wars' conclusion the chances of that trend to continue would have diminished. But here we are discussing that very same issue. Do they give the proper direction to the artist? I sometimes doubt this esp now we've had 3 different versions. I think he can just assume that Doom is doing something to try and fix it with potions, etc. Now he has hair when he didn't so maybe there's a little Rogaine mixed in!
