The Schlagg-Man is a villain in the DC Universe and an enemy of the Green Lantern Corps as part of the Sinestro Corps.

A native of planet Bismoll, Schlagg-Man is a career criminal. After he once bit through a policeman's neck, a judge ruled that Schlagg-Man's teeth be removed, and he has since had them replaced with Bismollian steel. Now, he can bite through anything, be it a steel door or the skull of the judge who pulled out his teeth.

Schlagg-Man was present on Qward when Kyle Rayner was captured and abducted to the Anti-Matter Universe.
