T'ania lived with her father, mother, sister and grandfather on Mars. One day, on T'ania's father's birthday, her grandfather came home early from worship to surprise him. J'onn walked in, appropriately surprised, and impressed that T'ania and K'hym kept a secret. Eventually, however, their family was attacked by the White Martians, a subterranean race who then wiped out dozens of their people in a Martian holocaust. T'ania was killed alongside her mother and sister, leaving only her father and grandfather left alive.
