Professor Night Professor Night is a fictional character created by Alan Moore in the "Supreme" comic book, wherein most heroes and villains are thinly disguised counterparts of DC icons. Although his name is derivative of Doctor Mid-Nite, the character is otherwise clearly intended be a counterpart of Batman. Professor Night works with Supreme both in a semi-regular partnership (a la "World's Finest Comics)" and as fellow founding members of the Allied Supermen of America, and its successor, the Allies (counterparts to the Justice Society of America and Justice League). He first appeared in "Supreme" vol. 3 #43.
