Nathan Fillion's Guy Gardner — and for good reason.

While many fans are excited for the return of Superman (David Corenswet), Lois Lane (Rachel Brosnahan), or even the menacing Lex Luthor (Nicholas Hoult), it’s Fillion’s Guy Gardner who stands out as the most intriguing and refreshingly bold addition to James Gunn’s DC Universe.

As Fillion himself put it: "He's a jerk!" And that’s exactly why he’s so exciting.

This isn’t the polished, by-the-book Green Lantern of old. This is a character unburdened by the need to be "good"—only fearless. That duality opens up a whole new dimension for the Green Lantern mythos. Guy Gardner isn’t here to be a hero in the traditional sense; he’s here to cause chaos, to challenge the system, and to embody the raw, unfiltered ego that often gets tamed in superhero stories.

His arrogance, his self-serving nature, and his cocky belief that he could take on Superman? That’s not just fun — it’s a long-overdue tonal shift. In a world where heroes are often defined by their morality, Guy Gardner is a necessary disruption. He's the guy who says, "I don't need to be nice—I just need to be strong."

And Fillion clearly relishes the role. As he said, the freedom comes from asking: “What’s the most selfish, self-serving action I can take right now? And that’s your answer.” That’s not just a great acting challenge — it’s a narrative game-changer.

This isn’t a character to win friends. He’s not here to be liked — he’s here to be a force. And in a DCU that’s already setting a tone of mythic grandeur with "Gods and Monsters," Guy Gardner could be the one who reminds us that not every hero wears a cape because they’re noble — sometimes, they wear it because they want to.

So yes, while Krypto might be adorable and Hawkgirl might bring a powerful new energy, the real shock to the system is Nathan Fillion’s Guy Gardner — a fearless, unapologetic, arrogant, and unpredictable Green Lantern who might just be the most exciting new character in the entire DCU reboot.

🔥 Answer: Nathan Fillion's Guy Gardner — because he’s not here to save the world. He’s here to own it.
