Cover Art of Swamp Thing (1986) #136.
*Resigned to his inhuman nature, Swamp Thing understood himself to be a freakish anomaly, an accident of nature. It was the mystic John Constantine who showed him the truth... that Swamp Thing is only the latest in a line of Earth Elementals stretching back to the beginnings of life... that he is linked to the Green, the metaphysical plant-life Web that girds the planet... that he is its protector, and it is his... that these things shall hold true until the day he takes root and joins his predecessors in the Parliament of Trees. *Source: Back of card
