Warning! This post contains SPOILERS for Supergirl (2026)
The DC Universe’s new Supergirl movie is now playing in theaters, giving audiences an even clearer idea of Superman’s age in comparison to his Kryptonian cousin. Supported by evidence in 2025’s Superman movie, the Man of Steel’s age in his next DCU adventure will likely create an interesting parallel with previous live-action Clark Kent.
Directed by Craig Gillespie and starring Milly Alcock as the titular Girl of Steel, Supergirl sees Kara Zor-El embarking on a cosmic adventure beyond Earth. Originally just partying on red-sun planets so she can get drunk, Kara ends up getting pulled into a major pursuit, helping young Ruthy Marye Knoll go after the villain known as Krem of the Yellow Hills, who also poisons Kara’s dog Krypto. That said, the movie also features some interesting reveals about Supergirl’s age in the DCU (as well as Kal-El’s).
While the exact year of Clark’s birth still hasn’t been fully confirmed, Supergirl narrows the possibilities quite a bit, seeing how the new DCU movie opens with Kara celebrating her own.
Supergirl’s Birthday Confirms Superman’s Age In The DCU

In the first act of Supergirl, Kara is confirmed to be celebrating her 23rd birthday while partying on a planet orbiting a red sun. This is because red solar radiation removes a Kryptonian’s powers as if they were back on Krypton, allowing Kara to get drunk when she otherwise couldn’t on Earth with its yellow sun and an accelerated metabolism.
Additionally, Kara later mentions to Ruthye that her cousin is around 8 years older than she is. Firstly, this confirms a major change in the DCU with the reveal that Kara was born after Kal-El (going back to her Silver Age origins). It’s also shown that Kara was born in Argo City years after it was separated from Krypton before its demise, having been protected by a force field created by her father.
Before he was Clark Kent, Superman was born Kal-El on a distant planet doomed to destruction. His parents Jor-El and Lara placed him in a rocket ship as an infant, sending him across the cosmos to Earth. What is the name of Superman’s home planet?
✓ Correct! Krypton was a scientifically advanced planet that exploded due to its unstable core. Jor-El, Superman’s father, was the only scientist who foresaw the catastrophe and managed to save his son by launching him toward Earth in a small spacecraft.
✗ Not faster than a speeding bullet on that one! The answer is Krypton. Thanagar is Hawkman’s homeworld, Apokolips is Darkseid’s domain, and Oa is the headquarters of the Green Lantern Corps. Krypton’s destruction is the defining event of Superman’s origin story.
02
Superman’s greatest love is a fearless, Pulitzer Prize-winning journalist who works alongside Clark Kent at the Daily Planet. She’s known for her relentless pursuit of the truth and for being one of the few people who sees both the hero and the man. Who is she?
✓ Correct! Lois Lane has been Superman’s primary love interest since her debut in Action Comics #1 in 1938. A brilliant investigative reporter, she’s as iconic as Superman himself — tough, smart, and unafraid to chase the biggest stories in Metropolis.
✗ Not faster than a speeding bullet on that one! The answer is Lois Lane. Diana Prince is Wonder Woman, Lana Lang is Clark’s high school sweetheart from Smallville, and Cat Grant is a gossip columnist at the Daily Planet. Lois Lane is Superman’s iconic partner.
03
Despite being nearly invulnerable under Earth’s yellow sun, Superman has one famous weakness — a radioactive mineral from the remnants of his destroyed homeworld. Exposure to it drains his powers and can even kill him. What is this substance called?
✓ Correct! Kryptonite is the irradiated remnants of planet Krypton. Green Kryptonite is the most common and deadly variety, but there are many other types — Red Kryptonite causes unpredictable behavior, Gold Kryptonite can permanently strip his powers, and Blue Kryptonite affects Bizarro.
✗ Not faster than a speeding bullet on that one! The answer is Kryptonite. Vibranium is from Marvel’s Black Panther universe, Nth Metal is tied to Hawkman, and Red Sun Ore isn’t a real DC substance. Kryptonite is the iconic green-glowing mineral that is Superman’s ultimate weakness.
04
In 1978, a then-unknown actor donned the cape and made the world believe a man could fly. His portrayal of Superman became the gold standard for superhero films and he starred in four Superman movies. Who is this legendary actor?
✓ Correct! Christopher Reeve’s portrayal in Superman: The Movie (1978) is widely regarded as the definitive live-action Superman. His performance perfectly balanced the heroic confidence of Superman with the endearing clumsiness of Clark Kent, setting the template every Superman actor has followed since.
✗ Not faster than a speeding bullet on that one! The answer is Christopher Reeve. Henry Cavill played Superman in the DCEU starting with Man of Steel (2013), Brandon Routh starred in Superman Returns (2006), and Tom Welling played young Clark in TV’s Smallville. Reeve was the original big-screen Superman.
05
Superman’s greatest enemy isn’t a superpowered alien — he’s a brilliant, ruthless human billionaire who believes Superman is a threat to humanity’s potential. This bald-headed genius has been Superman’s archenemy for over 80 years. Who is he?
✓ Correct! Lex Luthor is the ultimate foil to Superman — where Superman represents hope and selflessness, Luthor represents ambition and ego. Despite having no superpowers, his genius-level intellect and vast resources make him Superman’s most persistent and dangerous adversary.
✗ Not faster than a speeding bullet on that one! The answer is Lex Luthor. Brainiac is an alien android who collects cities, Darkseid is the god-like ruler of Apokolips, and Doomsday is the monster who famously killed Superman. But Lex Luthor is the definitive archenemy — Superman’s dark mirror.
06
After crash-landing on Earth as a baby, Kal-El was found and adopted by Jonathan and Martha Kent, a kind farming couple. They raised him with strong moral values in a small rural town. Where did Clark Kent grow up?
✓ Correct! Smallville, Kansas is the quintessential American small town where Jonathan and Martha Kent raised Clark with heartland values of honesty, compassion, and humility. It’s the foundation of who Superman is — not the powers from Krypton, but the character instilled by his Kansas parents.
✗ Not faster than a speeding bullet on that one! The answer is Smallville, Kansas. Gotham is Batman’s city, Metropolis is where Clark moves as an adult to work at the Daily Planet, and Coast City is Green Lantern’s home. Smallville is where the Kents raised Clark on their farm.
07
As Clark Kent, Superman disguises himself as a mild-mannered reporter working at Metropolis’s most famous newspaper, alongside Lois Lane and photographer Jimmy Olsen. Their editor-in-chief Perry White runs the newsroom. What is the name of this newspaper?
✓ Correct! The Daily Planet, with its iconic globe on the rooftop, is one of the most recognizable fictional newspapers in pop culture. Working there gives Clark Kent both a cover identity and a way to stay informed about threats to the city and the world.
✗ Not faster than a speeding bullet on that one! The answer is the Daily Planet. The Daily Bugle is Spider-Man’s Marvel universe newspaper, the Metropolis Star and Gotham Gazette are lesser DC publications. The Daily Planet — with its spinning globe — is Superman’s journalistic home.
08
This Kryptonian military commander was banished to the Phantom Zone for treason before Krypton’s destruction. He escaped and came to Earth seeking vengeance, famously demanding that others “Kneel before” him. His iconic portrayal by Terence Stamp cemented him in pop culture. Who is this villain?
✓ Correct! General Zod is one of Superman’s most terrifying foes because he has all of Superman’s powers but none of his morality. Terence Stamp’s portrayal in Superman II (1980) made “Kneel before Zod” one of the most quoted villain lines in film history. Michael Shannon later reimagined the role in Man of Steel (2013).
✗ Not faster than a speeding bullet on that one! The answer is General Zod. Bizarro is a flawed clone of Superman, Parasite drains powers through touch, and Metallo is a cyborg with a Kryptonite heart. General Zod is the Kryptonian military leader whose cry of “Kneel before Zod!” echoes through decades of Superman stories.

Are you the Man of Steel — or still stuck in a phone booth?
In previous continuities, Kara was actually Clark’s older cousin sent to care for him as an infant, though prolonged stasis and/or a wormhole resulted in her rocket arriving on Earth much later (while still being physically younger). Now, the math is more straightforward in the DCU. If Kara is 23 years old and Clark is around eight years older, that makes Superman around 31-32 years old during the events of Supergirl.
That lines up nicely with the opening text seen at the beginning of 2025’s Superman, which stated that Kal-El arrived on Earth roughly three decades before the events of the first DCU movie.
Superman’s Age In Man of Tomorrow May Create An Interesting DC Movie Parallel

Assuming the DCU continues to progress in real time (as James Gunn has previously suggested), Clark should be approximately 32 or 33 years old by the time Man of Tomorrow releases in 2027. What’s interesting is that this would put David Corenswet’s Superman at roughly the same age Henry Cavill’s Superman was when he publicly debuted and battled General Zod in Zack Snyder’s Man of Steel.
While their respective circumstances couldn’t be more different, it’s still a fun parallel between the two cinematic versions of the character. 33 is also the same age Jesus was when he was crucified and resurrected, a connection that was no coincidence for Cavill’s Superman, considering all the other ways Zack Snyder depicted him as a clear messianic figure in the DCEU.
Conversely, the DCU’s Superman will be in a very different stage of his superhero career. Rather than debuting to the world, Clark is already an established hero with trusted allies, well-liked by the public, and in a committed relationship with Lois Lane. However, there will be one interesting similarity with Cavill’s Superman beyond the two simply being close to the same age during the events of Man of Tomorrow.
Rather than facing General Zod, the DCU’s Superman will be taking on Brainiac, another cosmic villain with established connections to Krypton’s demise. Brainiac was also the intended villain for the planned Man of Steel 2 with Cavill. As such, it’s a pretty cool parallel coming down the line next year for the current Man of Steel and his predecessor.
