While Hal Jordan of Earth-One and Alan Scott of Earth-Two were the standard bearers of the Green Lantern identity, their lasting legacy would endure and promote others to follow their steadfast example. Among these were Katma Tui and Ma Hunkel, legends as well.
Katma Tui was an inhabitant of planet Korugar in Sector 1417, who was given the power ring and battery following her successors' downfall. The previous Green Lantern of her sector, also from her world, was a hero turned dictator in Sinestro. Soon after beginning her career as Green Lantern of her sector, she decided to quit in order to pursue a romantic relationship. To that end, the Guardians of the Universe who discharged the Lanterns to their duties sent Hal to convince her to remain a superheroine. She did, and years later when Jordan himself retired, Katma was assigned the task of training the next Green Lantern of his Sector 2814, John Stewart. Very shortly thereafter, the two fell in love, eventually married, and remained together on Earth-One.
Abigail Ma Hunkel was a resident of a big city on Earth-Two during World War II, in a community besieged with terror from the criminal element. When you daughter and another youth mentioned to her of how their Green Lantern, this one Alan Scott, would have cleaned up crime were he there... she became inspired to follow his example. As the original Red Tornado, Ma did not have his power ring nor his power battery, but did possess his heroic disposition. Eventually, Hunkel even ascertained where the Justice Society of America were meeting, and sought membership to their group. When this attempt failed, although Ma was granted posthumous honorary membership to the team, she returned to battling evil on her own.
