Gretchen was a human female pilot who acquainted fellow pilot Isabella and led the Rebellion starfighter squadron Firestar Girls during the Galactic Civil War. Gretchen participated in the Battle of Yavin and saved innocent lives aboard the Death Star before the battle station exploded.
In 0 BBY, Gretchen was a member of the Rebellion starfighter squadron primarily consisted of children, the Firestar Girls, which was stationed on the moon Yavin 4. While in preparation for an upcoming battle, Gretchen stumbled upon fellow young pilot Isabella, who she knew of prior. Due to their unlikely odds of winning, Gretchen invited Isabella to join the Rebellion with a rallying speech, though she denied the invitation and left. The rebel pilot Jek Tono Porkins promptly shouted how terrible the speech was and Gretchen quickly told him to shut up in annoyance.
Shortly before the destruction of the Galactic Empire's Death Star battle station during the Battle of Yavin, Gretchen, along with the rest of the Firestar Girls, evacuated all of the innocent workers serving the Empire out of the doomed space station, leaving just in time aboard a GR-75 medium transport. Saved from potential death, the rescued personnel shouted that they were okay.
After the battle concluded, Gretchen headed back to Yavin 4 and participated in the Royal Award Ceremony and an afterparty to celebrate their victory with the rest of the Rebellion. At one point during the celebration, Gretchen and the other Firestar Girls climbed on the Wookiee smuggler Chewbacca while he spun rapidly in joy and excitement. However, the party was cut short when Porkins glided and crashed into the gathering with a parachute, Gretchen taking the opportunity to insult the crashed pilot by ironically praising him.
Gretchen was a human female with long brown hair styled in a braid, dark blue eyes, and light skin. Gretchen was a brave pilot who joined the Alliance to Restore the Republic to fight the tyrannical Galactic Empire, though the young pilot also offered a pessimistic yet realistic perspective of the war with how low the odds and likeliness were for the Rebellion to win. During their time in the Rebellion, Gretchen led the Firestar Girls.
