Hal Jordan
Abilities
Power ring
* Allows flight, superhuman strength, and hard-light constructs with use of power ring.
Powers and abilities
As a Green Lantern, Jordan is semi-invulnerable, capable of projecting hard light constructions, flight, and utilizing various other abilities through his power ring which are only limited by his imagination and willpower. Jordan, as a Green Lantern, has exceptional willpower.
As Parallax, Hal was one of the most powerful beings in all of the DC Universe. In addition to his normal Green Lantern powers, he was able to manipulate and reconfigure time-space to his will, manipulate reality at a large scale, had vast superhuman strength which he demonstrated by being able to knock out Superman with one punch, a higher sense of awareness and enhanced durability. As Parallax he still was able to be harmed nearly just as easily as a normal Green Lantern but seemed to be able to endure more physical punishment. While Hal Jordan was Parallax he was never defeated by physical force, all of his very few defeats were of a changed mental state during or after the battle, which was usually the result of dealing with his own conscience and he would just give up, leave the battle and hide himself.

Sodam Yat is a fictional character, an extraterrestrial superhero published by DC Comics. He first appeared in Tales of the Green Lantern Corps Annual #2 (1986), and was created by Alan Moore and Kevin O'Neill. He operated as Ion, having become one of the most powerful characters in current continuity.
Powers and abilities
Like their Kryptonian cousins, the Daxamites gain a large number of abilities when exposed to yellow sunlight including super strength; flight; super speed; super hearing; X-ray, heat, microscopic, and telescopic vision; and super breath. While the Daxamites are invulnerable while under yellow sunlight, the substance lead is still very lethal to them even in small quantities, as Kryptonite is to Kryptonians. Due to his exposure to lead from lead shielding at a nuclear power plant and uranium stabbed into him by Superboy-Prime, Yat must wear his Green Lantern ring at all times to stop the lead poisoning or he will die within a few minutes.
The benevolent Ion entity bestows its host with powers similar to a Green Lantern Corps Power Ring and the Starheart. With those powers, Sodam Yat has been described by some as the most powerful superhero in the universe. However, access to the powers can be controlled through his power ring, which he is required to wear constantly, allowing the Guardians of the Universe to shut off his Ion powers. In the Legion of Three Worlds miniseries, it is revealed that being host to the Ion entity has allowed Sodam to survive, unaging, into the 31st century.

John Stewart is a fictional character, a comic book superhero known as Green Lantern, published by DC Comics. He first appeared in Green Lantern vol. 2, #87 (December 1971/January 1972), and was created by Dennis O'Neil and Neal Adams.
Powers and abilities
# John Stewart’s power ring provides him with the abilities of all other Green Lanterns; these abilities include flight and limited invulnerability.
# As with all other Green Lanterns, the ring is a weapon of the mind and powered by will, therefore only limited to the wearer’s imagination.
# Stewart was briefly taught by Ganthet on how to reroute his mind to think in the 'language of the spheres'- the first language of the universe- to evade telepathic detection by Fernus, the 'Burning Martian' identity of the Martian Manhunter; although the intensity of this method meant that John couldn't use it for more than a minute without burning his mind out, it has never been specified if this means that he cannot use it again or if he could use it at some future date if enough time has elapsed since his last use of it.
# Like all Green Lanterns, Stewart's personality affects his ring's creations, giving them a solid, architectural quality. In Green Lantern: Rebirth, Hal Jordan remarks that "everything John builds is solid". He also remarked that Stewart is the best flyer in the Corps.
# In Green Lantern (vol. 4) #26, it was shown that John's willpower exceeds the limit of his ring (when he tried to recreate a planet from scratch), a feat that had not been depicted before this point.
# John is a discharged member of the USMC with full combat training. In addition, he is an expert sniper.
# When he temporarily used Indigo-1's ring as a member of the Indigo Tribe, John was capable of accessing the powers of all Lantern Corps rings in his vicinity, even managing to harness the power of the Black Lantern Corps by drawing on the residual Black Lantern energy around Mogo's core. John is not shown to be significantly affected by the Indigo Ring's mind altering capabilities, although this could be because he was already capable of feeling compassion.
As well as his obvious powers as a Lantern, John has recently begun to demonstrate an ability to kill when he is certain the situation requires it, destroying Mogo in order to save the universe from the army of Krona-controlled Green Lanterns that Mogo would have created and later killing a fellow Lantern who was about to give in to torture and reveal vital information to their enemies.
