Grail is a DC comics villain who debuted in Justice League Vol.2 #40 (2015), making her one of the company's newest addition to its infinite gallery of rogues : despite her relative "youth" as a DC villain she is in-universe an extremely powerful and dreaded entity, being no less than the daughter of Darkseid himself.
Grail is the daughter of Darkseid, prophesied to cause great destruction at the behest of the Anti-God.
At the same time as the birth of Diana to Hippolyta, the Amazonian assassin Myrina gave birth to the daughter of Darkseid in secret, aided by Penelope and watched by the oracle Menalippe. Upon the birth of the young girl, Grail was defended by her mother from Penelope, who heard of the prophecy from Menalippe of the destruction that would be caused by the girl when she grew. After murdering Menalippe, Myrina fled Themyscira, bringing her daughter with her as the first Amazons to leave the island.
