The DC Comics event Flashpoint introduced Pandora, who later became central to the New 52 storyline.
Pandora is a DC Comics character associated with the magical vessel and the company’s major continuity changes. She first appeared in the 2011 Flashpoint event, which depicts a drastically altered timeline created after Barry Allen changes the past.
After Flashpoint, Pandora appeared in the New 52 publishing era and was connected to the mystery behind the altered DC Universe. Her role drew on the Greek myth but reworked Pandora as an active supernatural figure rather than simply the woman who opens a vessel.
Flashpoint is often confused with Crisis on Infinite Earths or Infinite Crisis, other DC crossover events involving major continuity changes. They are separate storylines from different periods. Pandora’s introduction belongs specifically to Flashpoint and its aftermath.
