As HBO prepares to launch Lanterns, one of the most anticipated entries in DC Studios’ new cinematic universe, many viewers are wondering what exactly a Green Lantern is. The upcoming eight-episode series stars Kyle Chandler as veteran Lantern Hal Jordan and Aaron Pierre as rookie John Stewart, following the two heroes as they investigate a mysterious murder in America’s heartland. Blending superhero mythology with a grounded detective story, Lanterns introduces one of DC’s richest comic-book legacies to a wider audience.

Unlike traditional superheroes, the Green Lantern is not a single character but a title shared by members of the Green Lantern Corps, an intergalactic peacekeeping force tasked with protecting different sectors of the universe. Each Lantern is chosen for exceptional courage and determination, receiving a powerful green ring that channels willpower into tangible energy. With the ring, Lanterns can create weapons, shields, vehicles, and virtually anything they can imagine. They are also capable of flight, space travel, and communicating across alien civilizations.
The concept first appeared in All-American Comics #16 in 1940 through Alan Scott, the original Green Lantern. Although Scott’s powers differed from the modern mythology, he paved the way for the cosmic version that would later become one of DC Comics’ defining franchises.

The face most fans associate with the Green Lantern name is Hal Jordan. Created by John Broome and Gil Kane, Hal debuted in Showcase #22 in 1959. A fearless former U.S. Air Force test pilot, Hal inherits his power ring from the dying alien Abin Sur and becomes one of Earth’s protectors within the Green Lantern Corps. Known for his confidence, rebellious nature, and willingness to take risks, Hal also serves as one of the founding members of the Justice League. In Lanterns, Kyle Chandler portrays an older, more experienced Jordan whose years of service have left both physical and emotional scars.
Joining him is John Stewart, portrayed by Aaron Pierre. Introduced in Green Lantern #87 in 1971, Stewart became the third human Green Lantern and has grown into one of the franchise’s most respected heroes. A former U.S. Marine and trained architect, Stewart approaches every mission with discipline and precision. His military background, leadership skills, and ability to create highly detailed energy constructs have made him one of the Corps’ finest officers. In the HBO series, Stewart begins his journey as a newcomer learning from Hal while becoming entangled in the investigation that drives the story.

Another familiar face in DC’s growing universe is Guy Gardner. First appearing in Green Lantern #59, Gardner is famous for his aggressive personality, oversized ego, and hot-headed attitude. Despite frequently clashing with teammates, he has repeatedly proven himself to be a courageous defender of the galaxy. Nathan Fillion first brought the character to live action in Superman before reprising the role in Peacemaker Season 2, establishing Gardner as an important figure in DC Studios’ interconnected franchise.
No Green Lantern story would be complete without Sinestro. Originally introduced in Green Lantern #7 in 1961, Thaal Sinestro began as one of the Corps’ greatest heroes and served as Hal Jordan’s mentor. Over time, however, his belief that order should be maintained through fear transformed him into one of DC’s most iconic villains. Played by Ulrich Thomsen in Lanterns, Sinestro’s complicated history with Hal is expected to add emotional weight and ideological conflict to the series.
Rather than serving as another traditional superhero adventure, Lanterns aims to combine cosmic mythology with the atmosphere of a crime thriller. By focusing on Hal Jordan and John Stewart’s investigation while exploring the larger Green Lantern mythology, the series offers newcomers an accessible entry point into one of DC’s most expansive universes. Whether audiences are longtime comic readers or discovering the Green Lantern Corps for the first time, Lanterns promises to shine a new light on these legendary guardians of the galaxy.
