SWAMP THING: Initial Realization there is no cure. He was never human "he's just a ghost". "A ghost dressed in weeds".

Swamp Thing #21 "THE ANATOMY LESSON".
Alan Moore, now given a blank slate regarding creative freedom regarding the character, decided to retcon Swamp Thing's origin to make him a true monster and not a human turned into a monster. For Saga of the Swamp Thing #21, Moore penned the famous story "The Anatomy Lesson", which had obscure super-villain Jason "Floronic Man" Woodrue autopsy Swamp Thing's body and discover that Swamp Thing's body was only superficially human, its organs little more than crude, nonfunctional, vegetable-based imitations of their human counterparts, meaning that there was no way Swamp Thing could have been human. This meant the Swamp Thing was not Alec Holland, but only thought that it was: Holland had indeed died in the fire, and the swamp vegetation had absorbed his mind, knowledge, memories, and skills and created a new sentient being that believed itself to be Alec Holland. Alec Holland would never be cured because there was nothing to cure. Woodrue also concluded that, despite the autopsy, Swamp Thing was still alive and in a deep coma due to the bullet wounds and imprisonment in cold-storage.
