Green Lantern Corps

Medphyll

A plant-based Lantern from J586.

Medphyll is a plant-based Green Lantern from J586. His biology and encounters with Swamp Thing show how the Corps connects with kinds of life far beyond human experience.

Continuity: Main DC comics continuity; this profile follows the cited era rather than asserting a permanent present-day status.

First appearance
Green Lantern (vol. 2) #11 (1962)
Story history — History and later developments — spoilers

Medphyll’s photosynthetic body includes vulnerable mind-stalks, and he can transfer his consciousness into nearby vegetation. His encounter with Swamp Thing gives that biology a narrative use beyond an unusual silhouette. Read Swamp Thing #61 for the meeting; his original introduction is much earlier, in Green Lantern #11 (1962).
