The Green Lanter Corp. has been known to be the protectors of the universe since 1959 with its first appearance in Showcase #22. The first human Green Lantern was Hal Jordan; his predilection for basic constructs like boxing gloves, baseball bats, and even colossal fists became rather stale and uninspired after the first decade. Instead of reenvisioning the character of Hal Jordan, DC Comics opted to introduce an African American Green Lantern by the name of John Stewart. This reimagining immediately solidified him as a popular character in the pantheon of DC superheroes.

Members of The Green Lantern Corps were being picked off by a sniper three space sectors away. The majority of the Lanterns fled for their lives, but only one stayed behind to fight off the long-ranged assailant and save his brothers-in-arms.

Another example of how amazing his constructs are: building an ancient alien device in mere minutes by briefly studying its blueprint.

Green Lantern was outnumbered on a foreign planet teeming with Black Lantern zombie-like enemies. Instead of fleeing, he decided to fight back against the odds and nearly lost his life until he was saved by his allies at the last second.

He relied on the power of his ring by creating a formidable armada of marines. The mind-blowing and somewhat baffling part is that he was controlling the troops, their weapons, and even the ammunition used. In other words, not only was he aiming the gun, but he was also controlling the trajectory of each bullet fired by the construct army.
