Swamp Thing, Vol. 5: Earth to Earth

At this point in the series, Moore has clearly fully developed his style as it is best known. He begins to abandon the classic style of comic book action, horror and drama, and tell mature tales about humanity and the state of the world.
In the last part of the book, one can sense in the Swamp Thing's isolation and subsequent will to create, the personal struggles illustrated in the Watchmen's character Dr. Manhattan. Both are near indestructible and their connection with humans is becoming less clear as they struggle to find their place in the universe. These ideas are what makes Moore's use of superheros truly unique and beautiful. It's not just about fighting the bad guys or overcoming some trial, it's about facing oneself and finding meaning in an often hostile universe.
