Despite revisions and changes in his origin story over the years, the idea that Superman is from a doomed planet called Krypton has been a near-constant in the mythology of the character. And although Supergirl joined Superman in the pantheon of Krypton survivors in 1959, a full 21 years after Superman first appeared in 1938, she’s always had a slightly darker version when it comes to the last days of Krypton. In a sense, most versions of Kara Zor-El are more knowledgeable about Krypton than Ka-El, simply because she didn’t show up on Earth as a baby.
In the first teaser trailer for the 2026 DCU Supergirl, Kara (Milly Alcock) makes it clear that her memories of the fall of Krypton run deep. And, this detail could suggest that Supergirl might finally nail one of the hardest DC origin stories to pull off: the rise and fall of the planet Krypton.
