Using a chemical compound of his own creation, the Green Man is able to turn others into plant minions who will do his bidding. So far, he seems to favor women, calling them his "brides." Once transformed, his victims operate under the Green Man's mental control, and exhibit a variety of hostile attacks and defenses, including such things as shooting thorns, controlling emotions, and snaring people with vines.
The Green Man has so far subjected three women to this process. Freeom Watch was able to subdue these women and restore them to normal. After observation by doctors, who confirmed that the process seemed to have had no permanent effect, they were released; their names have been withheld under the Supervillain Victim Rights Act of 1993.
