A signal was used by Gotham City whenever the city needs Batman's help.


In 2019, the signal was being used, when a wave of antimatter destroyed Gotham City and the entire universe.[1]



Season 5

Behind the scenes

  • In the DC comics, the Bat-Signal is a large projection lamp that casts the silhouetted shape of a bat across the sky of Gotham City. Commissioner James Gordon incorporated it as a means of contacting Batman, whenever he was needed and it was placed on the roof of the headquarters of Gotham City Police Department.


  • The Earth 89 Bat Signal may be Batman, but it is the Batwoman logo.
