Superman, the Man of Steel, may be Earth’s greatest hero, but even the mightiest saviour needs a companion. Enter Krypto, the Superdog, whose unwavering loyalty and superpowers make him more than just a pet—he’s a legend in his own right.
Krypto, the canine companion from Krypton, has captured hearts since his comic book debut in 1955. From being Superman’s steadfast ally to starring in his own animated series, Krypto’s journey is a testament to the unbreakable bond between a hero and his best friend.
If you watched the teaser for the upcoming Superman movie and thought, Wait, Superman has a dog now?—you’re right! Krypto, Superman’s trusty canine sidekick, has been part of his world since 1955. The white, red-caped dog has often been left out of Superman’s more serious stories, mainly because he’s considered a bit too goofy for the tone.
However, Krypto’s inclusion in this new film carries more weight than it might seem at first. According to director James Gunn, who co-heads DC Studios, how audiences respond to his interpretation of Superman will significantly impact the future of DC films. The new Superman movie is set to hit theaters on July 11, 2025, marking a major moment in the franchise.
Krypto the Superdog’s origin story
Krypto’s story begins on Krypton, Superman’s home planet. Created by Otto Binder and Curt Swan, Krypto first appeared in Adventure Comics #210. He was originally Jor-El’s test subject for the rocket technology that would later save his son Kal-El.
However, Krypto’s ship veered off course, leaving him to drift through space. Eventually, he landed on Earth, reuniting with a young Clark Kent. What followed was a touching story of reunion. The two rediscovered their shared heritage through adventures full of loyalty and love.
If you think superheroes can’t have pets or that a “Super Dog” is silly, you might be surprised. DC Comics has a long history of Super-Pets and their animal friends.
Krypto, Superman’s loyal dog, first appeared in the mid-1950s. This was about 20 years after Superman debuted in 1938. But long before Krypto, DC introduced Rex the Wonder Dog, who became part of the action-adventure genre, often appearing in military-themed comics. Batman has a four-legged sidekick named Ace the Bat-Hound.
Wonder Woman also has animal friends. Jumpa the kangaroo is especially loved by fans. Even Robin is not without his own unique pet—Batcow, a cow with a superhero twist.
Krypto the Superdog made his first appearance in Adventure Comics #210 back in March 1955, introduced as part of a Superboy story. – The flying puppy was created by writer Otto Binder and artist Curt Swan. It was intended to be a one-time character. However, he quickly won the hearts of readers and became a regular part of Superboy’s world.
Since then, Krypto has had many memorable moments in the superhero world. He has seen a big comeback in recent years. In 2005, fifty years after his debut, he got his own animated series, and has since appeared in Smallville, Titans on HBO Max, the 2022 animated feature DC League of Super-Pets (voiced by none other than Dwayne Johnson), and Superman & Lois on the CW.
However, despite his enduring popularity, Krypto was notably absent from the iconic Superman films of the late ’70s and ’80s starring Christopher Reeve. At that time, comic-book movies were rare. The idea of a flying dog might have seemed too strange. Audiences were just beginning to accept that a man could fly.
The absence of Krypto continued in later films like Superman Returns (2006) and Zack Snyder’s darker take on the Superman saga in Man of Steel, Batman v Superman, and his version of Justice League. In the more serious, somber tone of the Snyderverse, a lovable, flying dog simply wouldn’t have meshed with the mood of the story.
But now, with Krypto’s return in the new Superman film, it’s clear that the beloved Superdog is ready for his time in the spotlight once again. After all, what’s a superhero without his loyal companion?
Krypto’s powers that pack a punch!
Like Superman, Krypto possesses extraordinary abilities. His powers include:
- Super Strength and Speed: Krypto can match Superman in sheer physical prowess.
- Flight: Soaring through the skies is second nature to this canine.
- Heat Vision and X-Ray Vision: Krypto’s eyes can both incinerate and see through walls.
- Enhanced Senses: His canine instincts, paired with superhuman enhancements, make him an unparalleled tracker.
But beyond these powers, Krypto’s greatest strength lies in his loyalty and determination to protect his loved ones.
Krypto’s Role in Superman’s Life
Krypto is more than just a pet—he’s a bridge to Superman’s past and a reminder of his Kryptonian roots. Their bond transcends that of a typical owner and pet relationship. For Superman, Krypto is a confidant, a partner in battle, and a symbol of home.
Superman’s core message is about living in a world where bad things happen, yet always striving to be a friend to everyone and offering help where it’s needed, while also standing up against bullies and preventing harm. What better way to capture the essence of Superman than through the bond between a man and his mischievous dog?
Krypto’s presence also highlights the emotional depth of Superman. The moments where the Man of Steel lets his guard down, playing fetch or simply sharing a quiet moment with Krypto, remind us that even heroes need companionship.
Krypto in Pop Culture
Krypto’s journey from comics to screens has cemented his place in pop culture.
- Animated Stardom: The 2005 series Krypto the Superdog introduced the character to a younger audience, showcasing his adventures alongside other super-powered pets.
- Live-Action Appearances: In Smallville, Krypto appeared as a Labrador named Shelby, adding a grounded twist to the character.
- Krypto recently starred in DC League of Super-Pets, where his comedic and heroic sides shone brightly, earning him new fans worldwide.
Super pets in DC universe
In the DC Universe, Krypto stands tall among other super-pets like Ace the Bat-Hound and Streaky the Supercat. While each has their charm, Krypto’s connection to Superman and his central role in major storylines make him truly unique.
Krypto was inspired by our dog Ozu, who we adopted shortly after I started writing Superman. Ozu, who came from a hoarding situation in a backyard with 60 other dogs & never knew human beings, was problematic to say the least. He immediately came in & destroyed our home, our shoes, our furniture – he even ate my laptop. It took a long time before he would even let us touch him.
I remember thinking, “Gosh, how difficult would life be if Ozu had superpowers?” – and thus Krypto came into the script & changed the shape of the story as Ozu was changing my life. What better time to debut the not-so-good-good-boy Krypto than AdoptaShelterDog month. Btw, Ozu today, is, fairly often, a very good boy.
