A professor turned ruthless zealot. Lex Luthor: The iconic mastermind pulling the strings.
Season 4 picks up in the immediate aftermath of the destruction of the Kryptonian Worldkillers. Instead of celebrating, National City is reeling from a devastating revelation: This revelation, leaked by the Children of Liberty, shatters public trust.
The central engine of Season 4’s plot is introduced in the season finale of the previous season: a duplicate of Kara Zor-El, created by the energy of the Harun-El during the battle with Reign. This sets the stage for the "Red Daughter" arc, loosely inspired by the iconic comic storyline Superman: Red Son .
Let’s be honest: by the time Supergirl rolled into its fourth season, a lot of casual DC fans had already checked out. The first three seasons were fun, but they struggled with tonal whiplash—one minute dealing with alien slug monsters, the next preaching earnest social justice. But Season 4? It shed its cape and grew a spine.
The season ends with a powerful monologue from Kara Zor-El, who stands before a crowd of humans and aliens and says: “Fear is a story. Hate is a story. But you can write a new story. You can choose to be brave.”
