Ran

Ran is an Ascended Asgard whom was worshipped on Earth in ancient times as a Norse Sea Goddess. She is the only known Asgard to ascend having existed prior to her race's genetic degradation through cloning. In 2010 she helped Elizabeth Weir to ascend and later unascended her after she intervened to save Rodney McKay's life. She later sought Elizabeth's help against the Vanir who sought to force to unascend so that the might aquire her undamaged DNA and eggs to repair their cellular and genetic degradation and prevent their species extinction.
