In "The Saga of the Swamp Thing" (vol. 2) #22 (March 1984), the Floronic Man uses the Swamp Thing's body—now regressing to a plant-like state due to his inability to accept the new revelation about his origins, Woodrue literally eating parts of him—to contact the Green, which is composed of the life force of all plants on Earth. The experience drives the Floronic Man insane; he refers to himself as "Wood-Rue", and sets out to destroy all non-plant life on Earth by forcing the plants to produce an excess amount of oxygen to force humans and animals into extinction, in the belief that he is "saving" Earth from mankind. Woodrue is confronted by a revived Swamp Thing, who reveals to the Green that plants cannot survive without humans and animals, as his actions would deprive them of the carbon dioxide that "they" require to breathe that comes from humans and animals, forcing Woodrue to acknowledge that his actions are the actions of a man rather than a plant. The Green abandons the Floronic Man, who is then taken into custody by the Justice League after undergoing a complete mental breakdown.
