Dawnstar from the Legion of Super-Heroes, she is from Starhaven, a planet colonized by Native Americans abducted from Earth by an unknown alien race in the 13th Century. Her name is derived from the appearance on Earth of the planet Venus, the "morning star," which is why she wears an eight-pointed star ornament on her forehead. Dawnstar and her people are of Anasazi Indian heritage. Starhavenites have pairs of large white-feathered wings that grow out of their upper backs, the result of genetic engineering by the unknown alien race that resettled them and triggered their metagenes. You can imagine the psychological repercussion this character cause me as a child from looking at that  cleavage. Whoever genetically design this beauty was a genetic genius.
