Lashina was raised in Granny Goodness' orphanage and became the leader of the Female Furies when Big Barda left for Earth. Bernadeth, one of her fellow Female Furies, plotted revenge, as she desired leadership.

During a mission to recover Glorious Godfrey, a New God who had been imprisoned on Earth, Bernadeth betrays Lashina. Abandoned on Earth and wounded, Lashina is left in an amnesiac state. She subsequently assumed the identity of Duchess and joined the Suicide Squad.

During her time with the Suicide Squad, Duchess participates in several heroic missions, but when her memory returns, she plans to return to Apokolips. She manages to convince many members of the Suicide Squad to return with her where as others are outright kidnapped, such as Dr. Light, Count Vertigo and Amanda Waller. A vicious battle ensues between the Suicide Squad and the Apokoliptican forces, resulting in the death of many members of the Suicide Squad. Lashina, however, is focused on getting revenge on Bernadeth. After a long, savage battle, Lashina snaps Bernadeth's neck, killing her. Darkseid, appalled that Lashina had brought humans to Apokolips, then resurrected Bernadeth and killed Lashina. The surviving members of the Suicide Squad were allowed to return home.

Darkseid would later resurrect Lashina, who resumed her place with the Furies. She and Bernadeth agreed to share leadership, with Lashina acting as the field leader while Bernadeth leads them outside of the battlefield.

Lashina has continued to serve with the Furies since.
