Does Supergirl have a post-credit scene? No. Supergirl ends with Supergirl killing Krem of the Yellow Hills after Ruthye Marye Knoll finally finds him, and that final choice is the movie’s sharpest break from Supergirl: Woman of Tomorrow. The ending closes the chase rather than teeing up another scene.
Ruthye Marye Knoll and Supergirl
Ruthye Marye Knoll and Supergirl spend the film chasing Krem of the Yellow Hills across the galaxy, with Eve Ridley playing the young charge who has pursued him through the story. By the time the pursuit reaches its end, the movie has already turned the revenge plot into a question of restraint, and then decided not to keep that restraint intact.
Supergirl categorically rejects Ruthye Marye Knoll’s plan to kill Krem in revenge, which makes the fatal stab she later delivers harder to flatten into simple payback. Craig Gillespie and Ana Nogueira make the ending work by changing the source material’s moral bookkeeping instead of replaying it beat for beat.
Supergirl: Woman of Tomorrow
In Supergirl: Woman of Tomorrow, Supergirl ultimately takes Krem to the Phantom Zone, then the comic jumps ahead centuries. An eternally young Supergirl later visits an elderly Ruthye, and the comic version of Krem repents his crimes after enough lifetimes of self-reflection. The film drops that long tail and leaves the verdict on the battlefield.
Supergirl’s line in the comic, “I could not teach Ruthye to give up her thirst for vengeance,” points to the adaptation’s real shift: the movie keeps the chase, but not the same resolution. Milly Alcock’s Supergirl ends the conflict with Ruthye’s sword, and that single act redefines the character for the movie’s final frame.
Craig Gillespie and Ana Nogueira
Craig Gillespie and Ana Nogueira lean into a cleaner, harsher ending than the comic’s centuries-spanning one, which makes the movie easier to read as a closed story rather than a prologue. For viewers, the practical answer is simple: there is no after-credits scene waiting to reset Krem’s fate or soften the final blow.
