5 Green Lantern Facts That Will Help You Better Understand HBO's Lanterns

HBO's Lanterns, based on the Green Lantern franchise, stars Aaron Pierre as rookie space cop John Stewart and Kyle Chandler as seasoned intergalactic peacekeeper Hal Jordan. The show follows their journey as they uncover a conspiracy threatening to disrupt their apprenticeship. To better understand the series, here are some essential facts about the Green Lantern characters.

Green Lantern rings, which recharge with a cosmic battery, allow their wearers to create energy constructs of anything they can imagine through sheer willpower. Mastering these rings requires training, as seen in the HBO series. For example, Guy Gardner in the 2025 Superman film uses his ring to create giant hands to swat away enemy soldiers.

The Green Lantern Corps was established by the Guardians of the Universe, a group of beings who protect the cosmos from large-scale threats. The Guardians themselves are effectively immortal, blue, and small in stature with white hair. They've accumulated extensive knowledge about the universe over millennia, which aids their intergalactic peacekeeping efforts.

Interestingly, the Green Lanterns can be vulnerable to the color yellow, which represents fear—the opposite of their core trait, willpower and courage. The extent of this vulnerability varies depending on the era. In comics from the late 1950s or 1960s, Hal Jordan might be helpless against yellow objects, while newer versions reinterpret this concept due to Parallax, a creature made of pure fear.

The core of Lanterns focuses on Hal Jordan training John Stewart, despite Jordan's initial reluctance. This mirrors Jordan's complex relationship with Thaal Sinestro, an alien from the planet Korugar who once belonged to the Green Lanterns. Sinestro opposes the Corps, believing fear is a more effective tool for maintaining order.

In the current storyline, Sinestro has already left the Green Lanterns but remains involved in Jordan's life. Each Green Lantern is responsible for a sector of space across the universe, with a minimum of two patrolling Earth in the DC Universe, including Hal Jordan and Guy Gardner.
