The arc served as the beginning of Morrison's Batman run and was followed by a prose story about the Joker in "Batman" #663 and then the fan-named story arc "The Three Ghosts of Batman" ("Batman" #664–666). These two arcs and the Joker story were ultimately collected together in trade paperback form since many elements introduced in the first arc were used and expanded upon in the second arc. The story had a lasting impact on the DC Universe, introducing the character of Damian who would go on to co-star in two on-going monthly series for DC and appear in other comic books frequently.
