The teaser for Supergirl has fans biting their nails, and Krypto seems to be at the center of their anxiety. With our furry friend showing signs of distress in the clips, uncertainty looms large: will Krypto face his end in DC’s latest venture? That’s the burning question many are wrestling with.
Does Krypto Die in Supergirl 2026?

Though the teasers provide glimpses into the storyline, Krypto’s condition appears to tug at the heartstrings. One poignant moment shows him lying down, while Kara kneels beside him, tears streaming down her face. But before you let your imagination spiral into despair, I have some good news.
Supergirl draws inspiration from the comic Supergirl: Woman of Tomorrow, a tale filled with adventure and emotional highs. In this narrative, Krypto faces peril at the hands of the villain Krem, who inflicts serious harm. Fortunately, Kara finds a cure, and Krypto’s story doesn’t end there.
This adaptation means that Krypto is likely safe in Supergirl. While viewers will witness his struggles, a tragic ending seems unlikely. Instead, prepare for a storyline where courage and camaraderie ultimately prevail.
How Did Krypto Die in DC Comics?
In contrast, the comic universe hasn’t always been kind to Krypto. For those familiar with Whatever Happened to the Man of Tomorrow in Superman #423, you’ll recall a heart-wrenching moment when Krypto sacrifices himself to protect Superman. As the Kryptonite Man gains the upper hand, Krypto intervenes, bravely defending his friend by taking down the villain.
Sadly, this heroism comes at a great price. The exposure to a toxic dose of Kryptonite leaves Krypto unable to survive. Krypto dies a hero in the comics, and it’s a moment I hope remains untouched on screen. As we await the release of Supergirl on June 26, 2026, one question lingers: how far will the filmmakers go to draw from comic lore without breaking our hearts?
