Every Major New Character in HBO’s ‘Lanterns’ Explained: Sinestro, Antaan, Mogo, and More
Just two episodes into its run, HBO’s ‘Lanterns’ has already unveiled a wealth of new mythology, characters, and cosmic threats, transforming what began as a grounded murder mystery in small-town Nebraska into a sprawling narrative. For viewers trying to keep track of the expanding universe, the show has packed in enough deep-cut references to leave even seasoned comic readers seeking context.
This complexity is intentional. Created by Chris Mundy, Damon Lindelof, and Tom King, ‘Lanterns’ follows veteran Green Lantern Hal Jordan and new recruit John Stewart as their investigation into an alien incident in Rushville escalates into a larger conflict, drawing in villains, victims, and cosmic threats that reach back decades into Green Lantern comic lore.
With so much information presented so rapidly, here’s a breakdown of the show’s key new characters and concepts introduced thus far, along with their significance for the unfolding story.
Sinestro: Hal’s Fallen Mentor
Portrayed by Ulrich Thomsen, Thaal Sinestro is Hal Jordan’s former mentor and is widely regarded as one of the most significant villains in Green Lantern mythology. Sinestro initially trained Hal before being corrupted by the yellow energy of fear, leading to a failed coup against the Guardians of the Universe and his eventual expulsion from the Corps.

In ‘Lanterns’, Sinestro is depicted as imprisoned in a space facility, where Hal seeks his insight regarding the Manhunters. Showrunner Chris Mundy has noted that the writers aimed to explore what Hal learned from Sinestro’s training and how that influence has been passed on, intentionally or otherwise, to John Stewart.
Antaan and the Manhunters: The Season’s Central Threat
Played by Paul Ben-Victor, Antaan is an extraterrestrial character introduced as a survivor from a species targeted for genocide by the Manhunters, ancient robotic beings originally created by the Guardians of the Universe as a proto-Green Lantern police force before they turned rogue. Antaan is characterized by his commitment to uncovering the truth and a relentless desire for justice, leading some fans to speculate he shares similarities with the comics villain Atrocitus.

The Manhunters serve as the season’s primary antagonists, capable of shapeshifting into any species and adopting their technology. Their brutal history of annihilating entire civilizations initially drew the Green Lanterns’ attention, and the revelation that a Manhunter killed Abin Sur, the original bearer of Hal’s ring, connects the current mystery directly to the franchise’s foundational mythology.
Earl: Hal’s Unusual Houseplant
Amid the cosmic stakes, ‘Lanterns’ also introduces a quirky detail: Earl Jordan, Hal’s half-sentient, man-eating alien plant. John discovers Earl while exploring Hal’s home in Coast City, adding a strange yet comedic element to Hal’s otherwise guarded personal life.

Mogo: The Living Planet Behind a Clever Password

While John investigates Hal’s home, he also stumbles upon a hidden pocket dimension containing Hal’s old Green Lantern uniforms, accessed using the phrase “Mogo doesn’t socialize.” This line references a classic 1985 comic story by Alan Moore and Dave Gibbons, which introduced Mogo, a sentient living planet and one of the more bizarre members of the Green Lantern Corps.

In addition to these central figures, ‘Lanterns’ continues to expand its supporting cast. Nathan Fillion reprises his role as Guy Gardner from ‘Superman’, Laura Linney appears as one of the Guardians of the Universe in human form, and Kelly Macdonald plays Sheriff Kerry Kane, whose family ties directly into the town’s escalating mystery.
With eight episodes in total and new installments released weekly, ‘Lanterns’ shows no signs of slowing down in its pace of introducing new characters and mythology.
