First of all, this is the single best issue of the Fantastic Four ever. Written by Stan Lee, and with art by Jack Kirby, This Man, This Monster is a startling morality tale about a man who masquerades as The Thing in order to get close to Reed Richards so he can murder him. Instead, though, he quickly learns the nobility and heroism that comes with Ben Grimm's rocky hide.

Without spoiling the story, Kirby perfectly captured the tale's emotional tone through the Thing’s downtrodden expression, also leaving readers wondering why he was standing idly by as Reed floating helplessly through the Negative Zone in the background. A true classic of an issue.
