The Green Lantern Corps is a galaxy-spanning peacekeeping force, not a team made up only of Hal Jordan and John Stewart. The comics give Hal a long history as a veteran Lantern, while John first enters the story as a relief Lantern chosen by the Guardians. The TV series uses those characters in its own Earth-based murder mystery, so viewers need the basic mythology—not a comics reading marathon—to follow the setup.
What is the Green Lantern Corps?
In DC’s comic history, the Corps is an intergalactic police force governed by the Guardians of the Universe. Its members carry power rings that turn willpower and imagination into energy constructs. The Corps provides the larger setting behind the series’ two central Lanterns, but it is an ensemble: comics have featured many human and alien members.

That distinction matters going in. Hal and John are the leads in the show’s official description; they do not represent the entire Corps or its history.

Hal Jordan, the veteran
DC traces the modern Green Lantern mythology to Hal Jordan’s introduction in Showcase #22 in 1959. Hal is a test pilot when the dying Lantern Abin Sur’s ring chooses him for his strong willpower. Hal later meets the Guardians on Oa, establishing relationships central to the wider Corps mythology. DC’s history of the Green Lantern Corps recounts these origins.
#1 Best Overall
John Stewart, the recruit
John Stewart debuted in Green Lantern #87 in 1971. In that story, the Guardians ask Hal to train John as a relief Lantern. John is an architect, and that background connects naturally to the ring’s ability to create constructs: his imagination and design instincts are part of how he uses its power. DC’s feature on John Stewart discusses his introduction and character history.
John’s history has also changed across comic versions. DC notes that later portrayals made him a Marine, with versions combining Marine service and architecture. In the comics’ chronology, John becomes a full-time Lantern after Hal retires in 1984. Those details provide context, not a guarantee that the television adaptation will follow the same sequence.

How does the series use the comics’ setup?
Warner Bros. Discovery describes Lanterns as following “new recruit John Stewart and Lantern legend Hal Jordan, two intergalactic cops drawn into a dark, earth-based mystery as they investigate a murder in the American heartland.” The description establishes their contrasting roles and the show’s grounded mystery premise; it does not promise a scene-by-scene adaptation of a particular comic. See the Warner Bros. Discovery Pressroom series description.

| John debuts as a relief Lantern whom Hal is asked to train. | The official description calls John a new recruit and Hal a Lantern legend. |

DC’s 2023 announcement described the project as an Earth-based mystery connected to the wider DCU. That is useful as development context, but the current series description is the better reference for the show’s premise.
Why the Corps is bigger than its two leads
DC’s history describes a period when the comic title became Green Lantern Corps and gave alien Lanterns—including Kilowog, Katma, and Ch’p—a larger role. Hal, John, and Guy Gardner continued alongside those alien members. Remembering the ensemble helps explain why the Corps can matter beyond the immediate partnership at the center of the show.

Green Lantern #87 is the most direct issue-level introduction to John Stewart: it is his 1971 debut and shows the original relief-Lantern setup. DC says the issue is available through DC Universe Infinite. It is optional background, not required preparation for watching the series.

What to know about the show’s plot and availability
The comic origins above are background; the series develops its own story. DC’s September 23, 2026 feature describes a ten-year jump and plot developments involving Hal’s death. Those are major spoilers, so they are not necessary to know before starting the show.
