Base of Operations: The 7th Dimension
Occupation: Ruler, Would-be Conqueror
First Appearance: All-Flash Comics #32 (December 1947–January 1948)
This mysterious queen of the “7th dimension” attempted to take over Earth twice, then vanished for decades. The first time, Star Sapphire brought her planet close to Earth and began removing our world’s oxygen. She began by capturing the original Flash and his colleague Dr. Flura, stranding them on her own world with two minutes to live. Between the altered physical laws of the 7th dimension and the Flash’s speed, he was able to destroy her machine and stop the attack.
The Star Sapphire’s second attack banished Earth᾿s men to another dimension, leaving the female population for her to rule. Again, the Flash defeated her by making use of the differing rates of time in each dimension.
She made no further attacks on Earth for decades, until a new Star Sapphire surfaced in Coast City. This Star Sapphire, Carol Ferris, was an Earth woman chosen by the all-female alien race of Zamarons to be their queen. Presented with a powerful sapphire gem, she took on the persona of their ruler and came into conflict with Green Lantern. When the second Flash encountered the new Star Sapphire, he discovered that the original was manipulating her...and that she had been the Zamarons’ previous ruler, deposed and exiled for being unfit to rule. (This unfitness was likely in part due to her fear of men.) In the course of the battle, the ruler of the 7th dimension was trapped in the Star Sapphire gem. She has not been seen since.Text by Kelson Vibber. Do not copy without permission.

 There was originally no connection between the Star Sapphire of Earth-2 and the later villain. The two were not linked until Flash/Green Lantern: The Brave and the Bold #6 (March 2000).
 The Zamarons are actually the same race as the Guardians of the Universe, the beings who created the Green Lantern Corps. Eons ago, after the Oans had achieved immortality, the sexes separated and went to different planets. The future Guardians dedicated themselves to science and creating a galactic force for law, and the Zamarons, over time, became a warrior culture. No one knows why they choose a series of mortal queens.
 “The Amazing Star Sapphire” is reprinted in The Flash (first series) Annual #1, which was reprinted in a replica edition in 2001.
