The Huntress, also known as Helena Wayne, is a superheroine appearing in American comic books published by DC Comics. The character is the daughter of the Batman and Catwoman of an alternate universe established in the early 1960s and referred to as "Earth-Two", where the Golden Age stories took place. A modern-day predecessor of Helena Wayne as Huntress with no blood-relation to Batman or Catwoman, Helena Bertinelli, was additionally co-created by the character's co-creator Joe Staton in 1989, originally intended as a reinvention of the character following the events of Crisis on Infinite Earths, before being retconned as different characters.

"Crisis on Infinite Earths" is the sixth Arrowverse crossover event, featuring episodes of the television series Supergirl, Batwoman, The Flash, Arrow, and Legends of Tomorrow on The CW. The Supergirl, Batwoman, and The Flash episodes aired in December 2019 while the Arrow and Legends of Tomorrow episodes aired in January 2020. The events of the Black Lightning episode "The Book of Resistance: Chapter Four: Earth Crisis" and a two-issue comic book with characters and concepts unused in the live-action episodes also tied into the event.
