Gretti was a young man on board a spaceship in an ancient caravan of "space gypsies". The caravan was threatened by a hole between the Anti-Matter Universe and ours.The Green Lantern of Uxor, known as the Green Man, had come to close the hole and save the travelers. Although they could not save themselves, the people of the caravan refused the Green Lantern's help. In accordance with the ways of their ancestors, no one outside of the group was allowed to aid the caravan. The gods had placed the evil in their ancient path, and they must meet it bravely and alone.
In order to help the caravan, the Green Lantern gave Gretti a power ring. The young man was arrogant and impatient, but after the Green Lantern showed him what to do, Gretti closed the hole and saved his people. They returned to the caravan, with the young man regarded as a hero. The Green Lantern of Uxor left Gretti under the watchful eye of his grandmother.
While traveling with his people, Gretti continued to serve the universe as a Green Lantern even after the Green Lantern Corps was reestablished after its destruction. However, he was never compliant with its rules that he patrol his assigned sector. He patroled wherever his people's caravan took him, which was well beyond Sector 2828. The idea of remaining in one place was simply against everything he believed. Because he did continue to serve well as a Green Lantern, his wandering ways were overlooked by his superiors. His ways did add to the frustrations of his partner Green Man and of Stel, who acted when needed as Green Man's partner in Gretti's persistent absence.
Consumed by Greed
Gretti was forced to come back to Sector 2828 by his superior Green Lantern Salaak because the Guardians of the Universe themselves were coming with a squad of Green Lanterns. The Vega System was declared to no longer be off-limits due to the actions of Larfleeze, keeper of the Orange Light of Avarice. As the Green Lantern of the sector, he was expected to be there. Going against his beliefs, he met them on the planet Okaara to participate in the arrest of Larfleeze. Larfleeze chose not to surrender and unleashed his Orange Lanterns. Gretti found himself assaulted by four of them and all were demanding to have something of his. He could not understand what they wanted, and they each grabbed him by a limb, ripping him apart.
Gretti died there, and as was the way of the Orange Lanterns, they consumed his identity and his power ring as it tried to fly away to recruit his replacement. He was consumed by the Orange Lantern Corps and was reborn as an Orange Lantern himself, attacking John Stewart.
When Black Power Rings came to Okaara, Gretti is among the number of Larfleeze's victims who are raised as Black Lanterns. It is revealed here that Gretti originated on the planet Okaara.
