Floronic Man (Jason Woodrue)

Within DC Comics continuity Jason Woodrue is introduced as a botanist whose early career included the alias 'Plant Master' and a backstory noting exile from an interdimensional world called Floria in his Silver Age origin. In later stories Woodrue's body is transformed by an experimental formula (first depicted in The Flash #245, 1976) into a plant/human hybrid called the Floronic Man; in New 52-era stories he assumes the role of the Seeder affiliated with the Parliament of Trees (the Green). Across multiple continuities he alternates between a human scientist, a transformed plant-entity, and a contested champion or representative of the Green or its agents.

Descriptions across sources emphasize a variable plant–human hybrid appearance: skin resembling bark and hair that has turned into leaves (as described for The Flash #245 appearance), sometimes depicted as a regenerated plant body or, in one account, a surviving head kept alive that later regenerates plant tissue (Batman: Shadow of the Bat #56 summary). Visual specifics vary by storyline and era.

Originally a master botanist and plant scientist (Plant Master), Woodrue can control and manipulate plant life. After bodily transformation he exhibits plant physiology allowing large-scale biologically driven schemes (for example, attempting to force plants to overproduce oxygen), regenerative capacity from plant matter, and episodically the ability to interface with or draw power from the Green/Parliament of Trees — including storylines in which he briefly takes powers from Swamp Thing or is invested as the Seeder/Champion of the Green. Motivations shift between scientific experimentation and eco-centric fanaticism when influenced by the Green.
