Murder Bear is an entity of unknown nature that auditioned for placement in the Revenge Society (group). Bear's disturbing nature was frightening enough to spook Phantom Limb, Professor Impossible, and Baron Ünderbheit. Dean Venture stated he had no record of Murder Bear nor knew how the Bear gained entry. All of the questions the Revenge Society asked of Murder Bear were only answered by a dreadful heavy breathing sound. Murder Bear is not seen among the Revenge Society's ranks later, perhaps signifying it was too scary to get accepted into the newly formed villainous organization.
