Galatea (also known as Tea) is a clone of Supergirl and asset of Cadmus from Justice League Unlimited.
Galatea's appearance bears a striking resemblance to that of Power Girl, the Earth-Two counterpart of Supergirl in the DC Comics, with the white outfit and noticeably more mature physique than Supergirl, but loses the cape, blue gloves and boots. This is likely intentional, as she is seen with a red towel around her neck in the same manner as Power Girl's cape in one episode. Ironically, Power Girl herself would later get a clone named Divine, who shares a similar backstory and personality to Galatea. Her background is also reminiscent to that of the Superboy introduced by DC Comics in 1993, who is also a clone (of Superman) created by Project Cadmus.
In Greek mythology, Galatea was a marble statue of the love goddess Aphrodite, made by the sculptor Pygmalion and brought to life by Aphrodite to be his wife.
