Synopsis for "The Conqueror Worms"
Swamp Thing must rescue Abby and Matt Cable from Zachary Nail, an old foe of Dr. Thirteen's, and from mutant worms under his command (or so he thinks). He also discovers four human captives: Jefferson Bolt, Ruth, Luke, and the brain-damaged former sheriff Kain. Ruth is killed, infuriating her lover Bolt. The worms turn against Nail, so he destroys his underwater compound along with himself and the worms. The humans escape, but Swamp Thing is suddenly transported to the distant past.
- The origin of the mutated alligator is revealed in Swamp Thing #14.
- Professor Nail makes reference to the events of The Phantom Stranger (Volume 2) #14. Nail's disguise in that issue, seen on its cover, bears a striking resemblance to Swamp Thing.
