Known Powers

Normal human with Green Lantern Ring enhanced abilities granting the wielder the ability to create forms and devices of green energy from their imagination, transmute materials, phase through solid objects, become invisible, fly at supersonic speeds; achieve superhuman strength, speed, stamina, durability, immunity to harsh environments and an ability to communicate with all known sentient species.

Note: The imprisonment within the Central Power Battery of Parallax - a yellow being composed of pure fear - created an impurity making Green Lantern Rings incapable of manipulating objects colored yellow, and the champions of the Guardians of the Universe, the Green Lanterns, susceptible to the only thing that could break their will - fear.

With few exceptions the Power Ring is limited to a 24 hour charge and must be recharged in the Power Battery on a daily basis.


Green Lantern Central Power Battery: Repository of the mental energies of the Oan race.

Green Lantern Power Battery: Portable power batteries capable of drawing power from the Central Power Battery.

Green Lantern Ring: Device worn upon the finger to focus the energies of the Central Power Battery.

In brightest day, in blackest night, no evil shall escape my sight, let those who worship evil's might, beware my power, Green Lantern's light!

Appearing to be no more eventful than the birth of any Earth child, news of John Stewart's birth reached to the stars. On the distant planet Oa, the Guardians of the Universe recorded that the "Opener of Doors" had been born.

When Guy Gardner, the alternate choice for Green Lantern of Space Sector 2814, was injured, the current Green Lantern, Hal Jordan, was ordered by the Guardians to train a replacement should he become incapacitated as well. Their choice was John Stewart.

Stewart accepted the offer to be trained as a Green Lantern. Given a power ring and the uniform, Stewart discarded the mask, stating defiantly that he had nothing to hide.
