Nathan Fillion Details Why Guy Gardner Is In The Most DCU Movies & TV Shows

The DC Universe is giving the spotlight to one of the most beloved superhero organizations from the comics.
While James Gunn's DCU is building towards teams like the Justice League, numerous heroes are already making their way into DC Studios' cinematic continuity. As Chapter 1: "Gods and Monsters" is progressing forward, one character in particular is beginning to become a heavily recurring player across multiple projects.
In an interview with ScreenRant's Ash Crossan for Lanterns, Nathan Fillion, who is set to return as Guy Gardner in the HBO drama, was asked what it means for him to be the actor to have appeared the most in Gunn's DC franchise. The Rookie lead stated that, "To me, that means there's a chance that maybe I'll continue to be employed throughout my twilight years. That's my hope, at least."
When followed up with the question about why he thinks Guy Gardner is the connective tissue in the DCU, Fillion shared that "I like the idea that he is the connective tissue. He's the thread that weaves throughout the fabric of this universe." For the superhero veteran, he feels that "If you're existing, if you're a character in this universe, if you're watching this universe, he's in the back there somewhere. If you live in the DC Universe, you're gonna you're gonna be inundated with this guy... See what he did there?"
The Firefly actor elaborated, "But why is he the guy? Listen, I think if we're just kind of logically thinking it out, I think Guy Gardner is someone who embraces marketing." Fillion also admits that "I think he understands the importance of a brand, the brand for LordTech, the brand of the Justice Gang, the brand of Green Lanterns, the brand that is Guy Gardner."
In the end, Fillion added that "I think he is wary. I think he has a social media presence. I think he understands TikTok trends. I think he's got his finger on the pulse. He has financial goals. He wants to open a bar. He wants to do things, and his appearance, how he's perceived, that's important to him. So I think he's out there in the public eye. I think maybe that might be one of the reasons he exists across the projects he exists." After Lanterns season 1, there are more appearances lined up for the DC hero.

01
The Green Lantern Corps is an intergalactic peacekeeping force powered by the emotional spectrum. Each Green Lantern’s ring is fueled by a specific emotion. Which emotion powers the Green Lantern rings?
✓ Correct! Willpower is the green light on the emotional spectrum, sitting at the very center. The Guardians of the Universe chose willpower because it is the most stable and disciplined of all emotions, making it the ideal force for a peacekeeping corps that spans 3,600 sectors of space.
✗ Your ring’s charge is low on that one! The answer is Willpower. Hope powers the Blue Lantern Corps, Love fuels the Star Sapphires, and Courage isn’t a force on the emotional spectrum. Willpower — the green light — is the foundation of every construct a Green Lantern creates.
02
The most famous Green Lantern in DC Comics is a test pilot from Coast City who was chosen by a dying alien’s ring to become the Green Lantern of Sector 2814. Who is this character?
✓ Correct! Hal Jordan was introduced in Showcase #22 (1959), inheriting the ring from the dying alien Abin Sur. As a fearless test pilot, Hal was the perfect candidate — his indomitable willpower made him one of the greatest Green Lanterns in the history of the Corps.
✗ Your ring’s charge is low on that one! The answer is Hal Jordan. John Stewart is a fellow Earth Lantern and architect, Guy Gardner is the brash backup Lantern, and Kyle Rayner became a Lantern after Hal’s fall. But Hal Jordan is the test pilot from Coast City who defined the modern Green Lantern legacy.
03
The Green Lantern Corps is headquartered on a planet at the center of the universe, where the Guardians of the Universe reside. What is the name of this planet?
✓ Correct! Oa sits at the center of the DC Universe and serves as the headquarters of the Green Lantern Corps. It houses the Great Battery — the Central Power Battery that channels willpower energy to every Lantern ring across all 3,600 sectors of space.
✗ Your ring’s charge is low on that one! The answer is Oa. Maltus is the Guardians’ original homeworld before they migrated, Mogo is a sentient planet that is itself a Green Lantern, and Zamaron is the home of the Star Sapphires. Oa is the iconic green-tinged world at the heart of it all.
04
Sinestro was once the greatest Green Lantern before he was corrupted by his own desire for order and control. He created his own corps powered by a different emotion on the emotional spectrum. What emotion powers Sinestro’s yellow rings?
✓ Correct! The Sinestro Corps wields yellow rings powered by fear. Sinestro believed that fear was a more effective tool for maintaining order than willpower, and he recruited the most terrifying beings in the universe to prove it. The Sinestro Corps War remains one of the greatest Green Lantern storylines.
✗ Your ring’s charge is low on that one! The answer is Fear. Rage powers the Red Lanterns, Avarice (greed) fuels the Orange Lantern Larfleeze, and Death powers the Black Lanterns. Sinestro’s yellow rings channel fear — the direct opposite of willpower on the emotional spectrum.
05
The Green Lantern ring is one of the most powerful weapons in the DC Universe. It can create solid constructs of green light shaped by the wearer’s imagination. What is the ring’s one notable weakness in classic stories?
✓ Correct! For decades, the Green Lantern ring was powerless against anything colored yellow. This “yellow impurity” was later revealed to be caused by Parallax, the fear entity, imprisoned within the Central Power Battery on Oa. Once Parallax was removed, experienced Lanterns could overcome the weakness.
✗ Your ring’s charge is low on that one! The answer is the color yellow. Water was the weakness of the original Golden Age Green Lantern Alan Scott (whose ring was magic-based), not the Corps rings. The classic Silver Age weakness was yellow — leading to many creative villain strategies involving yellow objects.
06
John Stewart is a prominent Green Lantern who became a household name through his role in the Justice League animated series (2001–2006). Before becoming a Green Lantern, what was John Stewart’s profession?
✓ Correct! John Stewart was an architect before becoming a Green Lantern, which is reflected in his precise, structurally detailed ring constructs. While some later adaptations added a military background, his classic comic book profession is architect — and it shapes how he uses the ring in beautifully engineered ways.
✗ Your ring’s charge is low on that one! The answer is Architect. While the Justice League animated series gave John a Marine background, his original and most iconic profession in the comics is architect. This is why his ring constructs are known for their precise, detailed engineering — he literally designs them.
07
The emotional spectrum in DC Comics features seven corps, each tied to a different color and emotion. Which corps is powered by rage and wields red rings?
✓ Correct! The Red Lantern Corps, led by Atrocitus, is fueled by pure rage. Their rings replace the wearer’s blood with burning red plasma, and they vomit corrosive napalm-like blood as a weapon. Atrocitus founded the corps to seek vengeance against the Guardians for the Manhunter massacre of Sector 666.
✗ Your ring’s charge is low on that one! The answer is The Red Lantern Corps. The Sinestro Corps wields yellow rings of fear, the Orange Lantern is Larfleeze alone (powered by avarice), and the Black Lanterns are undead entities. The Red Lantern Corps, led by Atrocitus, channels pure burning rage.
08
Parallax is one of the most significant threats in Green Lantern lore. It is the living embodiment of fear and has possessed multiple Green Lanterns. In the iconic “Emerald Twilight” storyline, which Green Lantern did Parallax corrupt and drive to destroy the Corps?
✓ Correct! In “Emerald Twilight” (Green Lantern #48–50, 1994), a grief-stricken Hal Jordan — devastated by the destruction of Coast City — was corrupted by Parallax. He defeated every Green Lantern in his path, drained the Central Power Battery, and destroyed the Corps, becoming the villain Parallax. Geoff Johns later revealed that the fear entity had possessed Hal all along.
✗ Your ring’s charge is low on that one! The answer is Hal Jordan. After Coast City was destroyed by Mongul and the Cyborg Superman, Hal’s grief made him vulnerable to Parallax. He marched through the Corps, defeated every Lantern, and absorbed the Central Battery’s power. Kyle Rayner received the last ring after Hal’s fall, becoming the sole Green Lantern for years.

Are you worthy of the ring — or does your willpower need recharging?
While a premiere date hasn't been announced yet, Fillion is confirmed to appear as his Green Lantern in King's project. The showrunner teased that “We brought Nathan into Mister Miracle’s show, and doing that, it’s just so wonderful. He brings that energy to every aspect of it. And you would think it would be different tonally from [Lanterns], but it blends because that’s who Guy is. He’s that guy who is over the top. We all know that guy who’s a little bit like that.”
With Lanterns, Man of Tomorrow, and Mister Miracle, the audience will continue to get to see Guy Gardner's progression in the DCU, allowing Gunn's franchise to properly develop him as one of the staple members of this universe.
Lanterns season 1 airs on Sundays on HBO.
