Dr. Henry Killinger

.Dr. Henry Killinger is a recurring character who first appears in the Season 2 episode I Know Why the Caged Bird Kills. While Dr. Killinger's exact nature and reason for existence remain a mystery, his actions indicate some degree of loyalty to or stewardship of The Guild of Calamitous Intent, but his motives and goals remain unclear, as does his degree of connection to The Guild. He seems to be a generally benevolent force to those he appears to, working with them (if they're willing) to help them become better villains.
