Meet the Voice Cast Behind DC League of Super-Pets

The 2022 animated blockbuster DC League of Super-Pets brought together an unprecedented assembly of Hollywood A-listers to breathe life into the four-legged heroes and two-legged icons of the DC Universe. Directed by Jared Stern, this film shifted the spotlight from the Justice League to their loyal animal companions. Leading the ensemble are global superstars Dwayne Johnson and Kevin Hart, whose real-life friendship translates perfectly into the dynamic between Krypto the Superdog and Ace the Hound.

While the film serves as a comedic action-adventure for families, the depth of its voice cast provides layers of humor and heart that appeal to long-time comic book enthusiasts. From Keanu Reeves’ brooding take on Batman to Kate McKinnon’s maniacal performance as the villainous guinea pig Lulu, the talent behind the microphones defines the movie's identity.

The Leading Duo: Krypto and Ace

At the heart of the story is the relationship between Krypto, Superman’s powerful but socially awkward Labrador, and Ace, a cynical shelter dog with a heart of gold.

Dwayne Johnson as Krypto the Superdog

Dwayne "The Rock" Johnson voices Krypto, a character who shares Superman’s Kryptonian abilities but lacks basic social skills with other dogs. Johnson brings his trademark charisma to the role, balancing Krypto’s arrogance with a vulnerable fear of losing his best friend, Clark Kent, to Lois Lane. Interestingly, Johnson’s involvement went beyond voice acting; his production company, Seven Bucks Productions, was instrumental in bringing this project to the big screen. His performance captures the "golden boy" energy of a hero who eventually learns that true strength comes from teamwork rather than individual power.

Kevin Hart as Ace the Hound

Kevin Hart provides the voice for Ace, a Boxer mix who has spent years in a Metropolis animal shelter. Ace is the practical, street-smart foil to Krypto’s idealistic hero. Hart, known for his high-energy comedic timing, delivers a surprisingly grounded performance here. Ace’s backstory—involving a misunderstood sacrifice for a human family—adds a layer of emotional gravitas that Hart handles with sincerity. The natural comedic chemistry between Johnson and Hart, seen in numerous live-action films, is the engine that drives the movie’s most successful scenes.

The Ragtag Group of Shelter Pets

When the Justice League is captured, it falls to a group of shelter animals recently imbued with superpowers to save the day. This group features some of the most creative voice-casting choices in modern animation.

Vanessa Bayer as PB the Pig

PB is a potbellied pig who idolizes Wonder Woman and gains the ability to change her size. Vanessa Bayer, a Saturday Night Live veteran, utilizes her talent for playing overly enthusiastic and slightly anxious characters to make PB the emotional anchor of the group. Her portrayal of PB’s journey from self-doubt to embracing her "inner Amazon" provides a relatable arc for younger audiences.

Natasha Lyonne as Merton the Turtle

Merton is an elderly, nearsighted turtle who gains the power of super-speed. Natasha Lyonne delivers perhaps the most distinct vocal performance in the film. Using her gravelly, fast-talking New York accent, Lyonne turns Merton into a scene-stealing source of irreverent humor. The irony of a slow turtle becoming the fastest being in the room is played for laughs, but Lyonne’s comedic delivery makes the character memorable beyond the initial gag.

Diego Luna as Chip the Squirrel

Chip is a fearful squirrel who discovers he can generate electricity from his paws. Diego Luna, known for his dramatic roles in the Star Wars universe, voices Chip with a frantic energy that perfectly matches the character’s constant state of panic. Chip’s evolution into a brave member of the team allows Luna to showcase a range of vocal emotions, from high-pitched squeaks of terror to confident heroic declarations.

The Antagonists: A New Threat to Metropolis

Every superhero story needs a compelling villain, and DC League of Super-Pets delivers a unique foe in the form of a hairless guinea pig with a vendetta.

Kate McKinnon as Lulu

Lulu is a former LexCorp lab animal who believes she is Lex Luthor’s true partner. Kate McKinnon brings her unparalleled ability to play "unhinged" characters to this role. Lulu is both terrifying and hilarious, a tiny creature with the intellect of a supervillain and a desperate need for validation. McKinnon’s vocal range allows Lulu to transition from a manipulative strategist to a screaming kaiju-sized monster with ease.

Marc Maron as Lex Luthor

While Lulu is the primary physical threat, the classic DC villain Lex Luthor plays a pivotal role. Voiced by comedian and podcaster Marc Maron, this version of Luthor is arrogant, dry-witted, and constantly annoyed by the "lesser" beings around him. Maron’s deadpan delivery provides a sharp contrast to the high-stakes action, making Luthor a formidable and entertaining secondary antagonist.

The Icons of the Justice League

While the focus is on the pets, the film features the most famous members of the Justice League, each voiced by notable actors who put their own spin on these legendary characters.

John Krasinski as Superman / Clark Kent

John Krasinski voices the Man of Steel, portraying him as a doting pet owner and a noble hero. Krasinski’s voice carries a sense of warmth and reliability that fits the classic "Big Blue" persona. His interactions with Krypto are central to the film’s theme of friendship and the difficulty of balancing personal relationships with professional responsibilities.

Keanu Reeves as Batman / Bruce Wayne

In what many fans consider a stroke of casting genius, Keanu Reeves voices Batman. Reeves leans into the dark, brooding, and solitary nature of the Dark Knight, using his famous stoic delivery to create a comedic version of the character who is obsessed with his own tragedy. When Reeves’ Batman eventually bonds with Ace at the end of the film, it serves as a satisfying emotional payoff.

Jameela Jamil as Wonder Woman

Jameela Jamil voices Diana Prince with the regal authority and kindness expected of the Amazonian princess. While her screen time is limited compared to the main pets, her presence is vital to PB’s character development, providing the inspiration for the shelter pig to become a hero.

The Rest of the League

• John Early as The Flash: Early brings a youthful, slightly neurotic energy to Barry Allen.
• Dascha Polanco as Green Lantern (Jessica Cruz): Polanco portrays Jessica Cruz with a focus on her willpower and role as Chip’s eventually-realized companion.
• Jemaine Clement as Aquaman: Known for his eccentric comedy, Clement gives Arthur Curry an appropriately over-the-top, "king of the ocean" vibe.
• Daveed Diggs as Cyborg: Diggs provides a tech-focused and cool-headed voice for Victor Stone.

Supporting Roles and Notable Cameos

The depth of the Super-Pets cast extends to the smaller roles, featuring industry veterans and surprising guest appearances.

• Olivia Wilde as Lois Lane: Wilde voices the intrepid reporter and Clark Kent’s fiancé, serving as the source of Krypto’s initial jealousy.
• Maya Erskine as Mercy Graves: Lex Luthor’s loyal and lethal assistant is voiced by the PEN15 star.
• Thomas Middleditch and Ben Schwartz as Keith and Mark: These two voice a duo of guinea pigs who serve as Lulu’s henchmen. Their natural comedic rhythm as a pair adds a layer of fun to the villain's team.
• Alfred Molina as Jor-El: In a nod to superhero cinema history, Molina (known for his role as Doc Ock) voices Superman’s Kryptonian father in a brief but majestic cameo.
• Yvette Nicole Brown as Patty: The kind-hearted but overwhelmed owner of the animal shelter.

The Post-Credits Surprise

In a meta-reference to the changing landscape of the DC Cinematic Universe at the time, Dwayne Johnson also voices Black Adam and his dog, Anubis, in a post-credits scene. This cameo allowed Johnson to bridge the gap between his animated role and his live-action debut as the anti-hero, creating a humorous interaction between Krypto and the ruler of Kahndaq.

Comprehensive Voice Cast and Character Table

For quick reference, here is the complete breakdown of the primary actors and the characters they portrayed in DC League of Super-Pets.

Why the Casting Matters: Behind the Scenes

The casting of DC League of Super-Pets was a strategic move by Warner Bros. to ensure the film appealed to a broad demographic. By pairing Dwayne Johnson and Kevin Hart, the studio guaranteed a level of chemistry that is difficult to manufacture in a recording booth. In many animated films, actors record their lines separately, but the history between these two leads allowed the animators to capture the nuances of their well-established comedic timing.

The choice of Keanu Reeves as Batman was also a significant cultural moment. Fans had long campaigned for Reeves to play a version of Batman, and his performance in this animated setting allowed him to explore the "grimdark" tropes of the character while leaning into the absurdity of a man who dresses as a bat and refuses to pet dogs.

Director Jared Stern emphasized that the goal was to find voices that felt "real" despite the fantastical nature of the plot. Natasha Lyonne’s Merton, for example, wasn't just a fast turtle; her voice gave the character a sense of age and weariness that made her newfound speed even funnier. This attention to detail in the vocal performances helped the film achieve a "Certified Fresh" rating on Rotten Tomatoes and made it a hit with audiences worldwide.

Comparison to DC Comic Book Origins

While the film takes liberties with the source material, many of the cast members are playing characters with deep roots in DC history.

1. Krypto: First appeared in Adventure Comics #210 in 1955. In the comics, he is often a white German Shepherd, whereas the movie depicts him as a Labrador Retriever.
2. Ace the Bat-Hound: Originally appeared in 1955's Batman #92. While he has been various breeds in the comics (including a German Shepherd and a Great Dane), the film's version as a Boxer mix highlights his "tough-guy" shelter background.
3. The Legion of Super-Pets: The concept of a team of super-powered animals dates back to Adventure Comics #293 (1962). The original team included Krypto, Streaky the Super-Cat, Beppo the Super-Monkey, and Comet the Super-Horse. The 2022 film updated this roster with PB, Merton, and Chip to provide a more diverse set of powers and personalities.

Conclusion

The success of DC League of Super-Pets is inextricably linked to its phenomenal cast. By securing a mix of legendary action stars, beloved comedians, and respected dramatic actors, the filmmakers created a vibrant world where pets are just as heroic as their human counterparts. Whether it is the banter between Johnson and Hart or the dry wit of Marc Maron and Keanu Reeves, the vocal performances elevate the film from a standard animated feature to a standout entry in the DC filmography. For anyone looking for a blend of superhero action and heartfelt animal stories, the talent behind these characters ensures an experience that is as entertaining as it is emotionally resonant.
