This graphic novel is notable for introducing Damian Wayne, the son of Batman and Talia al Ghul, who later becomes a significant character in the DC Universe.
While initially published as an out-of-continuity story, elements and characters from Son of the Demon, particularly the existence of Batman's son with Talia al Ghul, were later integrated into the mainstream DC Comics continuity.
The concept of Batman having a biological son with Talia al Ghul, first explored here, became a foundational element for subsequent storylines, most notably Grant Morrison's run on Batman and Robin.
