Supergirl | Trapped by the Master Jailer: Kara’s Powers Stripped! 🚨🔒🪐

A mysterious vigilante known as the Master Jailer emerges in National City, ruthlessly hunting and executing escaped Fort Rozz aliens. Hiding in plain sight as a police detective, he believes he’s upholding the legacy of Kara’s mother, Alura. Using red sun radiation, he weakens Supergirl and locks her in a secret cell. While imprisoned, Kara speaks with another captured alien who reveals he’s changed—just trying to live a quiet, honest life on Earth. This conversation challenges Kara’s beliefs about justice and redemption. Luckily, Alex and the DEO track the lair, break in, and stop the execution—freeing Kara just in time!
