The Green Man
A bizarre and wondrous plant-life entity, linked to the planetary biosphere itself.
This organism was formerly the sorcerer hero Simon Magus. In the aftermath of a great spell, his very being had become merged with Earth's biosphere. Amnesiac, no longer sure of who he was, he took on a new identity as the enigmatic Green Man.
In 1984, he manifested before an E.N.G.I.N.E. base that was genetically engineering plant-based foot soldiers. Their births and deaths drew him to the site, where he encountered Royal Williams, there on his own agenda. His magic insight sensed that Williams was on a path into darkness, and he warned him as much.
