The Superman Standard
When we think of a hero from Krypton, we think of Kal-El. Sent to Earth as an infant, his loss is foundational but abstract. He didn’t watch his parents die or see his planet crumble; he learned about it from recordings and artifacts. His heroism is aspirational,
built on the values of his adoptive parents, the Kents. He strives to be a beacon, a perfect symbol of hope, because his connection to Krypton is one of legacy, not memory. This has been the dominant portrayal in film for over 40 years. Superman represents the ideal immigrant story: someone who arrives with nothing and enriches his new home, honoring a past he never truly knew. He is an idea, a near-perfect moral compass untainted by the visceral trauma of his world’s end. That’s the default setting for Kryptonian heroism, and it’s a powerful one. But it’s not the only one.
A Tragedy Remembered, Not Inherited
Kara Zor-El’s origin story is fundamentally different and far more brutal. She wasn't a baby bundled into a ship. In most modern tellings, she was a teenager, old enough to have a life, friends, and a future on Krypton. She was tasked with protecting her infant cousin, Kal-El, but her ship was knocked off course, trapped in suspended animation while he rocketed to Earth. When she finally arrived, decades later, the baby she was meant to protect was a grown man, a god among mortals. Her world was gone, her family was dead, and her purpose was obsolete. This isn’t an inherited tragedy; it’s a lived one. Superman lost a home he never knew. Supergirl lost *her* home. This grief is not a backstory detail; it is the core of her character. She is a survivor plagued by PTSD, a stranger in a strange land who remembers exactly what she lost.
The 'Woman of Tomorrow' Blueprint
James Gunn’s new DC Universe is wisely basing its Supergirl movie on Tom King and Bilquis Evely’s comic series, *Supergirl: Woman of Tomorrow*. This is not a story about an upbeat heroine trying to fit in. It’s a gritty space-western where a disillusioned, hard-drinking Kara, celebrating her 21st birthday alone on a remote planet, is pulled into a bloody quest for revenge. A young alien girl’s world is destroyed, and she seeks a killer. She tries to hire a hero, but finds Kara instead—a hero seething with unresolved anger. The story uses Kara’s personal trauma as a lens through which to view justice and heroism. She isn't fighting for truth, justice, and the American way; she's fighting because she knows the rage of losing everything and sees it reflected in someone else. Her heroism is cynical, weary, and fueled by a pain Superman can’t possibly comprehend. It’s messy, but it’s real.
More Than a Female Superman
Here lies the film’s greatest challenge. For too long, Supergirl has been presented on screen as a lighter, sometimes less confident, version of her cousin—essentially “Superman, but a girl.” The studio, and by extension the audience, may be tempted to see a female hero and expect a more emotionally attuned, less angry character. But the entire point of the *Woman of Tomorrow* take is that her pain makes her harder, not softer. The movie must resist the urge to sand down her rough edges. It has to trust that audiences are ready for a Kryptonian hero who isn’t a flawless symbol. Milly Alcock, known for her fiery portrayal of Rhaenyra Targaryen in *House of the Dragon*, is perfectly cast for this version of Kara. The job is to let her be angry, let her be grieving, and show that heroism born from that dark place is just as valid—and perhaps even more relatable—than the perfect hope embodied by her famous cousin.
