Greco Stucks is an agent of The Activity Consortium and one of the notable Mediums in its ranks, being a large
lizardman manlizard. He is only briefly seen during Spender's visit to the Consortium's dream base conversing with fellow spectral Cinnamon Stix.
Greco's one appearance to date has centered on his bemoaning his status as a Medium, specifically how his spirit has turned him into a large lizard hybrid. While he feels comfortable with his arrangement as a
lizardman manlizard, he feels discomfort over people seeing his spirit's monstrous effects on his body before they see him as a person. Prefers to be called a "manlizard" as opposed to "lizardman".
His initial and only appearance has him conversing with his coworker Cinnamon, although the relation between the two, if any, is unknown.
