James Gunn’s Superman trailer doesn’t waste time. With just a handful of frames, it gives us a clear message: this isn’t just Superman’s story. This is how a universe is reborn. Superman is joined by a brash Green Lantern, a fierce Hawkgirl, and even a canine companion that’s already stealing hearts.

Gunn’s bold vision promises to bring together a fresh and dynamic roster of heroes. It also comes with a promise to challenge everything we thought we knew about DC on the big screen. Huge responsibility on Gunn, right? Well, who are these heroes, and what do they mean for the future of the franchise? Let's dig in.


Superman: a fresh take on a timeless icon

Superman has been portrayed in countless ways, each reflecting the era in which he appeared. Christopher Reeve’s portrayal in the late 1970s and 80s was the epitome of hope and optimism. He was a symbol of pure goodness.

Henry Cavill’s take leaned into the weight of being an outsider, exploring a grittier, more conflicted version of Clark Kent. Brandon Routh brought a nostalgic reverence to the character in Superman Returns.

David Corenswet’s casting marks a new chapter for the Man of Steel. His youthful yet powerful presence suggests a Superman who blends tradition with modernity. Based on the teaser, Gunn’s Superman seems more focused on vulnerability than invincibility—a hero who represents both hope and the struggles of those he protects.

The teaser trailer offers glimpses of the classic Superman—flying through the skies, cape billowing—but with an emotional depth that makes this portrayal unique. Gunn has emphasized that Superman will explore the duality of being both an alien and a human.

This is new for Superman on screen, for this theme was touched on in the comics but rarely explored in live-action adaptations. This Clark Kent seems poised to inspire through his humanity instead of powers and strength.


1) Guy Gardner: the lantern with zero chill

Green Lanterns have always been a core part of the DC mythos, but none are quite like Guy Gardner. Where Hal Jordan is the classic hero and John Stewart is the disciplined soldier, Gardner is the loud, brash anti-hero who wears his heart—and his ego—on his sleeve. His appearances in animated series like Justice League Unlimited captured his arrogance and penchant for stirring up trouble, while his comic book arcs showed a more complex side: a hero whose bravado masks a deep sense of loyalty and justice.

Nathan Fillion’s cast as Gardner? It feels like a match made in heaven. Known for his charm and comedic timing, Fillion has the right mix of charisma and edge to bring this unconventional Lantern to life. Gardner’s role in Superman seems like a deliberate choice to add some chaos to the DCU. His interactions with Superman could highlight their sharp differences in personality and approach to heroism.

In the teaser, Gardner’s bowl cut and cocky grin stand out, hinting at a character who is unapologetically himself. Some fans believe his presence could lead to a deeper exploration of the Green Lantern Corps. Maybe his brash personality could clash with Hal Jordan's more composed nature in future films. From what we have seen so far, it seems logical to say that Gunn is laying the groundwork for a Lantern legacy that’s anything but ordinary.


2) Hawkgirl: a warrior with wings and a weighty history

Hawkgirl' has a rich and often convoluted background. Her story spans ancient Egypt, alien worlds, and many reincarnations. In animated series like Justice League and Justice League Unlimited, Shayera Hol became a fan favorite with her tough attitude and intricate character development.

In live-action, Hawkgirl has often been a supporting character, such as in Legends of Tomorrow, where her storyline couldn't live up to her comic book legacy.

Gunn's version, played by Isabela Merced, looks set to give Hawkgirl the attention she deserves. The teaser highlights Hawkgirl’s iconic wings while showing her in action. It suggests that she will be portrayed as both graceful and deadly.

Fans speculate her appearance could be tied to Thanagar, her alien homeworld, or even Hawkman, last seen in Black Adam.

Gunn could explore her relationships with other heroes in Superman. She might clash with Superman ideologically or bond over their shared sense of duty. Her character thrives on balancing independence and loyalty. Gunn's choice to feature Hawkgirl shows his commitment to portraying female heroes as complex and powerful as their male counterparts—or even more.


3) Krypto: the super-dog we didn’t know we needed

Krypto has won the hearts of audiences in various media before. And he has done it again. In Krypto: The Super Dog, we get to see both his playful and heroic side. Krypto becomes a key ally to Superman in Superman: The Animated Series.

With this, we get an open window to a more compassionate side of Superman. Furthermore, it highlights the importance of loyalty, friendship, and companionship. And in Gunn's Superman? Will he offer comic relief? Will he be a symbol of Superman's humanity? Or will he bring emotional depth to the film? Can we expect cute moments? Darker moments? All of the above?

The inclusion of Krypto in Gunn's Superman film suggests he's willing to embrace the whimsical elements of Superman’s lore. And, from what we've seen from him, we can expect something that feels real and relatable.

Krypto has immense potential for both action-packed and emotional scenes. The trailer shows a glimpse of the possibilities. Imagine a superpowered doggo soaring through Metropolis. Will Krypto take down enemies with a wag of his tail?

Beyond the spectacle that he can potentially bring, Krypto’s bond with Superman could provide some of the film’s most heartfelt moments—reminding audiences that even the greatest heroes need someone to lean on.


Other heroes and the mysteries they bring

The teaser doesn’t stop at Superman, Guy Gardner, Hawkgirl, and Krypto. While these characters dominate the spotlight, the trailer is filled with tantalizing glimpses of what could be.

Fans have speculated about fleeting images of alien landscapes that might connect to Thanagar or Oa, the Green Lantern Corps’ headquarters. Could Hawkman make a surprise appearance, or is there a deeper connection to cosmic forces in DC lore? Metamorpho and Mr. Terrific, most probably will.

Gunn's Superman trailer has sparked speculation about Metamorpho and Mister Terrific. Though their roles (or visuals) aren't confirmed, James Gunn's storytelling hints at a layered approach, leaving fans curious about how these characters might fit into Superman's story.

James Gunn’s work is known for its attention to detail and its mix of humor, heart, and action. This teaser follows the same approach, hinting at a larger story. With each frame and every shot inviting us to speculate, can we not get excited for more clues in this reimagined DC universe?


Conclusion: Building a DCU worth believing in

James Gunn isn’t just rebooting Superman. He's been crafting a manifesto for what the DCU can and should be. This is the foundation of a universe where heroes are messy, layered, and unapologetically human.

With Superman as the heart, Guy Gardner as the chaotic wildcard, Hawkgirl as the fierce warrior, and Krypto as the loyal companion, Gunn assembled a cast that feels as diverse in personality as it is in potential. Their dynamics, conflicts, and growth will be key to defining what this new era of DC storytelling looks like.

All of this doesn’t just promise a great Superman movie: it promises a DCU that’s bold, interconnected, and unafraid to take risks. If this is Gunn’s vision, then the future of the DCU looks brighter than ever.
