Test pilot Hal Jordan went from being a novelty, the first-ever human Green Lantern, to one of the most legendary Lanterns to ever wield a power ring. Hal Jordan’s life was changed twice by crashing aircraft. The first time was when he witnessed the death of his father, pilot Martin Jordan. The second was when, as an adult and trained pilot himself, he was summoned to the crashed wreckage of a spaceship belonging to an alien named Abin Sur. Abin explained that he was a member of the Green Lantern Corps, an organisation of beings from across the cosmos, armed with power rings fuelled by the green energy of all willpower in the universe. Upon his death, Abin Sur entrusted his ring and duties as the Green Lantern of Earth’s space sector to Hal Jordan. Hal’s life as a Green Lantern has not been easy. He’s had to fight not only enemies, but often friends, colleagues and loved ones. But despite the strain his Green Lantern identity has put on his life, Hal is an honest man who can operate without fear, and is always willing to protect those in need—whether alone, with the Corps or alongside the Justice League and Earth’s other superheroes. For Hal has sworn the oath of every Green Lantern—that no evil will escape his sight.

Hot-headed, unruly, second Green Lantern and prone to breaking the rules, Guy Gardner isn't always the most likeable hero but he's proven time and again to be a worthy Green Lantern. If Guy Gardner had been just a few miles closer to a dying alien named Abin Sur, he—and not test pilot Hal Jordan—would’ve become the first human being to join the Green Lantern Corps, the group of intergalactic heroes guided by the Guardians of the Universe on the planet Oa. Eventually, however, Guy became a Green Lantern himself, quickly earning a reputation as a rebel without a cause who doesn’t know when to shut up. But whenever evil needs to be fought or lives are threatened, Guy Gardner is here to help. Just don’t expect him to be nice about it.

The third human to ever wield a Green Lantern ring, John Stewart's leadership and tactical brilliance is legendary throughout every sector of the galaxy. Earth has produced many fine members of the Green Lantern Corps, but among its finest stands U.S. Marine Corps veteran John Stewart. Although he was originally chosen by the Guardians of the Universe as the “alternate” Lantern, called in to wear the power ring whenever Hal Jordan was incapacitated, Stewart has grown to become a leader of the Green Lantern Corps. A former architect, Stewart creates his power ring constructs differently than his fellow Lanterns, as they are never hollow. He always builds them from the inside out, down to the last nut and bolt—the result of his keen architectural mind. Stewart also differs from some of Earth’s other Green Lanterns in that he has chosen not to conceal his identity behind a mask. John Stewart has suffered numerous tragedies in his life. But he’s always overcome them and emerged even more dedicated to the ideals for which the Green Lantern Corps stands.

The sworn protector of Sector 2814, the power ring-bearing Jessica Cruz has conquered her fears and brought renewed honor to the Green Lantern Corps. On the surface, Jessica Cruz may seem an unlikely candidate for membership in the Green Lantern Corps, and her road to ring wielder was a long and twisted one. But she holds the distinction of being Sector 2814’s first official female representative in the Corps. The result of a tragic event in her youth, Jessica suffers from crippling anxiety, and before becoming an official Lantern, was chosen to wear another kind of weapon—the evil Ring of Volthoom. Unlike a Green Lantern Ring, the Ring of Volthoom chose Jessica for succumbing to fear, not overcoming it. Although the ancient ring was at first a corrupting influence and exerted its control over Jessica, she was eventually able to break free and use its powers for good. After an act of self-sacrifice, Jessica was given a Green Lantern Ring and chosen to become a member of the Corps. Developing as a Green Lantern alongside her frequent partner, Simon Baz, Jessica still has a lot to learn and many personal obstacles to overcome, but she’s proven herself time and time again as one of the Earth’s most heroic protectors.

Once a Green lantern for the numbered sector also known as fourteen seventeen (1417) Steadfast in his belief of moral superiority and methods of maintaining order, Sinestro formed the Sinestro Corps, harnessing the yellow energy of fear, to not only combat the Guardians, whom he sees as the main obstacle on the path to intergalactic peace, but to also strengthen the Green Lantern Corps. For it is Sinestro’s opinion that the Green Lanterns have long since been held back by their creators. Highly intelligent with an almost unbreakable will, Thaal Sinestro will do anything to achieve control and thereby order—control over his emotions, control over others, and even control over the entire universe.
