History: Iolande was a princess of Betrassus who was inducted into the Green lantern Corps. She had difficulty following orders from superiors because of her sense of entitlement, so she was often assigned entry-level tasks to show her humility.

(Green Lantern Corps II #17) - Iolande joined Soranik Natu in the defense of Earth against the Sinestro Corps during the Sinestro Corps War.

(Green Lantern IV #25) - The Sinestro Corps War raged on Earth, and while Iolande, the GLC and an army of superheroes battled the Corps the Anti-Monitor prepared to unleash an anti-matter wave to destroy Earth. With Earth’s destruction, the entire 52 would fall, and he would once again rule all that was. The GLC ruptured the heart of Anti-Monitor’s Warworld, the Sinestro Corps central power battery, and created a shield around Warworld and the Monitor. The ensuing blast nearly destroyed the Anti-Monitor, and he was finished off by Superman-Prime, who betrayed him for having destroyed his home, Earth-Prime. GL Hal Jordan defeated Sinestro in personal combat, and the Sinestro Corps, lacking any leadership, fled Earth. The heroes rejoiced and began rebuilding the damage the Sinestro Corps did.

Iolande received a profile in Green Lantern / Sinestro Corps: Secret Files #1.
