FIRST APPEARANCE: Superman TAS "New Kids In Town"
Laurel Gand was a Daxamite superheroine, and a member of the Legion of Super-Heroes. She is descended from Eltro Gand, the older brother of 20th Century hero Valor. As a Daxamite, she gains superhuman powers and abilities from being near a yellow sun, rendering her a vastly above average combatant. Laurel first appeared as a side effect of the time-altering Glorith recreating the universe in her own image.
As a child Laurel lived with her parents on one of the orbiting space stations that, among other things, served as a line of defense against invasion. Her mother, the station commander, insisted that Laurel know how to operate the station's weapons, training that proved critical when the Khunds attacked. Laurel was able to activate the defenses, utterly destroying the Khundian fleet and earning her both their fear and their enmity. She was declared an enemy of the Khundish empire. To ensure her safety, she was given a secret identity and sent to Earth where her Daxamite physiology would help protect her. Shortly afterward, she was invited to join the fledgling Legion of Super-Heroes.
Andromeda was created to since after the Crisis on Infinite Earths wiped out Supergirl. Andromeda would fill in place of Supergirl.
