The first trailer for ‘Supergirl‘ doesn’t just introduce Milly Alcock’s Kara Zor-El, it quietly rewrites how the DC Universe wants us to think about Krypton. The same tragic truth has been told to the audience over decades: Krypton exploded, Superman escaped, and that was the end. It was clean, sudden, and catastrophic. However, ‘Supergirl’s trailer hints at something much more disturbing.
Kara herself hints at it when she explains how different she is from her cousin. Superman has faith in the good in people. Kara believes in the truth. That difference is not philosophical; it is experiential. The haunting Krypton imagery in the trailer is not there to be nostalgic. It is there to create trauma.
Superman Lost A Planet, Supergirl Lost A Childhood

Among the most prominent scenes in the ‘Supergirl’ trailer is not Kara flying or fighting, but Krypton itself. We observe a world that is peaceful, developed, and well-organized. The citizens of Kryptonia are dressed in white ceremonial attire. Cities are glowing with futuristic design. It is not a planet that is on the edge, but a civilization that feels that it still has time. Then comes the twist. When Krypton starts to rip itself apart, a huge protective barrier forms around a city, lifting it away from the planet as everything else collapses.

Kara subsequently dismisses the notion that Krypton died in a day. She is not correcting history; she is correcting a lie. That floating city is Argo City, and its survival fundamentally changes what Kara endured. In the majority of ‘Superman’ adaptations, the destruction of Krypton happens immediately. Sad, yes, but short. Kara’s version of events, however, is prolonged. Her home didn’t vanish. It lingered, drifted, and decayed.
This is the only reason why the worldview of Supergirl is so different from that of Superman. On Earth, Clark grew up with loving parents and was not exposed to the trauma of the fallen Krypton. Kara, on the contrary, saw her world disintegrate bit by bit. She remembers faces and names. The DCU is not merely making Kara and Clark different to add flavor to the characters. It is based on her whole personality on survivor’s guilt. Kara isn’t more cynical because she’s harsher; she’s more honest because she’s seen what false hope costs.
DCU Will Finally Show Argo City’s Slow And Painful Extinction

The emotional core of Supergirl comes directly from its source material: Tom King’s ‘Supergirl: Woman of Tomorrow’. And it’s one of the most acclaimed DC stories of the last decade. Moreover, judging by the trailer, the movie is taking the most devastating concept of the comic. In that tale, Argo City manages to survive Krypton’s explosion when Zor-El, Kara’s father, constructs a dome of protection around the atmosphere.

Kara, her parents, and about eighteen thousand Kryptonians survive, floating in space on a piece of their lost planet. Initially, survival is triumphant. However, it turns cruel. The soil under their feet is poisoned as Argo City flies close to yellow suns. The radiation of kryptonite oozes into all things: the earth, the air, their flesh. People begin to fall ill. Zor-El orders lead shielding to be constructed in a desperate attempt to protect the city. It isn’t enough.
Kryptonians die, not in a heroic blaze, but painfully, slowly, and helplessly. Thirteen thousand die of radiation poisoning. Kara grows up surrounded by funerals. This is the childhood that Kara carries with her. Once the asteroids finally penetrate the lead shielding, it is all over for Argo City. Sealed. Zor-El builds a rocket modeled after his brother Jor-El’s design, not to save the city, but to save his daughter.
Kara is sent away, alone, while every remaining Kryptonian dies. In contrast to Superman, Kara does not come to Earth as a baby without any recollection of loss. She comes as a survivor, angry, grieving, and conscious that she survived and everyone else did not. The ‘Supergirl’ trailer virtually confirms that this backstory will be translated to the DCU. And that decision tells all about the type of hero Kara Zor-El will be.
