A Nightmare on Yancy Street

 

Even though the Thing was my favorite FF member, I didn't mind when She-Hulk took over for a while. She meshed well with the rest of the team, no doubt due to John Byrne's excellent writing.

I don't think I've seen the Fantastic Four go up against Nightmare before, or even had much interactions with magical characters in their own title.

Ben Grimm, the Thing, is my favorite Fantastic Four member. I guess it also holds true for a lot of readers since he was the only one who spun off successfully on a solo series (a number of them, actually). Marvel was trying to do the same with the Human Torch, but with little success. I guess Ben's troubled nature while still trying to be a positive guy resonated more with fans, as opposed to Johnny's cocky young man who has everything going for him.
