If you were reading DC Comics in the late 1990s, you probably remember how weird things got for Hal Jordan. He wasn't the shiny hero anymore. He was a mass murderer. Or a god. Or maybe just a guy who lost his mind after his home city got nuked. It was a mess, honestly. Then came Green Lantern Emerald Knight, a story arc that started in Green Lantern #100 and basically tried to fix the unfixable. It brought back a young, naive Hal Jordan from the past to face a present where he was already the universe's biggest villain.
It worked. Sorta.
People forget how much of a risk this was. At the time, Kyle Rayner was the only Green Lantern left. He was the "torchbearer." But fans were screaming for Hal. DC’s solution wasn't a full resurrection—not yet—but a time-travel mishap that forced the rookie Kyle to mentor the legend who would eventually grow up to kill all his friends. Talk about awkward.
The Time Kyle Rayner Met His Executioner
The whole thing kicks off because of a fight with a villain named Grayven. Kyle gets tossed through time, lands in the past, and accidentally brings a Silver Age Hal Jordan back to the "modern" era.
Think about that dynamic for a second.
You have Hal, who is basically a 1960s fighter pilot with a "can-do" attitude, walking into a gritty 90s world where he’s told he becomes a cosmic genocidal maniac named Parallax. It’s heavy stuff. Writer Ron Marz didn't shy away from the trauma. He leaned into the idea that Hal was looking at his own future and absolutely hating what he saw. The contrast between Hal’s clean-cut heroism and Kyle’s artistic, struggling-everyman vibe created a chemistry that most modern team-ups just can't replicate. It wasn't just a superhero fight; it was a character study on legacy and the fear of failure.
Why Emerald Knight Changed the Green Lantern Mythos
Before this arc, the "Green Lantern Corps" was dead. Gone. Zero members besides Kyle. By bringing Hal back—even a younger version—Marz proved that the franchise couldn't survive on just one person forever. It laid the groundwork for the eventual return of the Corps years later in Green Lantern: Rebirth.
There’s a specific moment in Green Lantern #101 where Hal sees the memorial for the Corps. It’s gut-wrenching. He sees names of friends he hasn't even met yet, or friends he knows he is destined to kill. This is where Green Lantern Emerald Knight shines. It uses time travel not as a gimmick for a cool fight, but as a way to explore the burden of being a hero. Hal Jordan isn't just a guy with a ring; he’s a man wrestling with a pre-determined fate.
Is he a hero if he knows he’ll eventually become a monster?

That’s the question that kept readers buying issues back then. It gave Hal his dignity back. It showed that the "true" Hal Jordan was still a good man, even if a future version of him had been corrupted by fear and an alien parasite (which we didn't fully know about back then, thanks to Geoff Johns' later retcons).
The Parallax Problem
Let's be real: Parallax was a hard pill to swallow. In the Emerald Twilight arc, Hal went rogue because he wanted to recreate Coast City. He killed Kilowog. He snapped Sinestro’s neck. He stripped the Guardians of their power.
When Green Lantern Emerald Knight happened, DC was trying to find a middle ground. They wanted to keep Kyle Rayner as the lead because he was selling well, but they realized they had alienated a huge portion of the fanbase by turning Hal into a villain. This story served as a "soft" apology. By showing the young Hal’s reaction to his older self’s crimes, the writers were telling the fans: "We know. We get it. Hal is still a hero at heart."
It also introduced the concept of the "Emerald Knight" as a title that transcended just one person. It wasn't just about the ring; it was about the willpower to do the right thing when everything—including your own future—is against you.

Reading Order and Key Issues
If you're looking to dive into this specific era, you can't just jump in anywhere. You need to hit the highlights to understand the emotional stakes.
- Green Lantern #100: The big centennial issue where it all starts. Double-sized, lots of action, and the first meeting of the two lanterns.
- Green Lantern #101-106: The core of the "Emerald Knight" arc. This is where the time-travel consequences really start to bite.
- Green Lantern #106: The resolution. Hal has to go back. If he stays, the timeline collapses. It’s one of the most underrated "goodbye" scenes in comics.
The art by Paul Pelletier during this run is also worth a mention. He captured the classic look of Hal’s costume—the white gloves, the simplified mask—and contrasted it beautifully with Kyle’s more complex, armored 90s suit. It visually represented the clash of generations.
The Legacy of the Emerald Knight Today
Looking back from 2026, it’s easy to see this story as a precursor to the "Multiverse" madness we see in movies today. But back then, it felt personal. It wasn't about infinite earths; it was about two guys sharing a mantle.
The "Emerald Knight" title eventually found its way into other media, including the animated film Green Lantern: Emerald Knights, which took the name but changed the story into an anthology. While the movie is great, it doesn't quite capture the "fish out of water" tragedy of the original comic arc. The comic version is much grittier. It’s more about the internal psychological struggle of Hal Jordan than the external battles of the Corps.

Actionable Steps for New Readers
If you want to actually experience the Green Lantern Emerald Knight storyline without spending a fortune on back issues, here is how you do it:
- Check DC Universe Infinite: The digital subscription service has the entire Ron Marz run. Search for Green Lantern (1990-2004) and start at issue #100.
- Look for the "Kyle Rayner Vol. 2" Trade Paperbacks: DC has been reprinting this era in thick collections. The "Emerald Knight" arc is usually tucked into the later volumes of the Kyle Rayner trades.
- Read "Emerald Twilight" First: To really feel the impact of Hal’s return, you need to see his fall. Read issues #48-50 before you touch #100. It makes the "reunion" between Hal and the ghost of his reputation so much more powerful.
- Ignore the Retcons (For Now): When reading this, forget everything you know about the "Yellow Impurity" or the Parallax entity. Read it as it was intended in 1998—a story about a hero who fell from grace and his younger self trying to understand why.
The story remains a testament to why Hal Jordan is such a compelling character. He isn't perfect. He’s impulsive, he’s arrogant, and sometimes he’s dangerous. But at the end of the day, he’s a man who will choose to sacrifice his own happiness—and even his life—to ensure the universe has a protector. Whether you call him a Green Lantern or an Emerald Knight, that core remains the same.
