Power Girl's origin has gone through revisions, but over time has reverted to her original conception as the Supergirl of Earth-Two. The 1985 limited series "Crisis on Infinite Earths" eliminated Earth-Two from history, causing her to be retconned as the granddaughter of an Atlantean sorcerer known as Arion. This was an unpopular change and writers depicted the revised Power Girl inconsistently. The 2005–2006 "Infinite Crisis" limited series then restored her status as a refugee from the Krypton of the destroyed Pre-Crisis Earth-Two universe. Following DC's 2011 "Flashpoint" storyline and New 52 reboot, Power Girl's origin was retold as the Supergirl of "Earth 2", cousin and adopted daughter of Superman, who during evil Fourth World New God Darkseid's invasion of Earth 2 becomes stranded in the main continuity of Earth 0, subsequently adopting the name Power Girl to hide her true identity. She returned to her source Earth in the story "Earth 2: World's End" (2014–2015).
