Rorschach (Walter Joseph Kovacs) is a fictional antihero in the graphic novel limited series Watchmen, published by DC Comics. Rorschach was created by writer Alan Moore with artist Dave Gibbons, but as with most of the main characters in the series, he was an analogue for a Charlton Comics character, in this case Steve Ditko's the Question. Moore also modeled Rorschach on Mr. A, another Steve Ditko creation on whom the Question was originally based.
