The Green Lantern wields an Oan ring, from which all his powers derive. All power ranks are based on the user's will power (equal to his Psyche rank, which is Unearthly for Green Lantern). The ring must be recharged every 24 hours, or it will cease to operate. The ring, or any of its constructs, is ineffective against anything colored yellow. The Guardians of the Universe can use the ring to communicate with Green Lantern at will. The ring has the following capabilities:
Martial Arts B * Piloting * Sales
The Justice League of America * The Green Lantern Corps * Alan (Green Lantern) Scott
Hal Jordan, a test pilot for Ferris Aircraft, had been checking over the company's new flightless training module when he and the module were suddenly yanked skyward by a bolt of emerald energy. The green glow carried the module to the heart of the Sierra Madre mountain range, and deposited it in front of what appeared to be the wreckage of an alien spacecraft.
Cautiously, Jordan entered the ruined ship, to find a red-skinned alien clad in a green-and-black uniform lying on the floor. The alien's name was Abin Sur, and he was dying.
Through telepathy, Abin Sur explained that he was a member of the intergalactic peace-keeping force known as the Green Lantern Corps, and that it was his duty, as death approached, to pass on his power to someone who was utterly honest and born without fear. By the light of his power ring, he could see Hal Jordan was both. Quickly, Abin Sur explained the use of his power ring and its attendant power battery, then having placed the ring on Jordan's finger, Abin Sur expired.
Following Abin Sur's final instructions, Jordan donned Sur's uniform, then used the power ring to bury Abin Sur and the remains of his spacecraft beneath one of the Sierra Madre mountains.
Returning to Ferris Aircraft, Hal Jordan began a lengthy career as the Emerald Crusader known as Green Lantern. He soon met the Guardians of the Universe, those immortal old men who had founded the Green Lantern Corps untold centuries before, and eventually rose to the forefront of the Corps.
As the years passed, Hal Jordan's personal life had many ups and downs. For a time, he left Ferris Aircraft and pursued careers as an insurance investigator, a toy salesman, and in independent trucker. But, eventually, he returned to Ferris Aircraft and, more specifically, to Carol Ferris, owner of the aircraft company and the woman Jordan loved.
