Synopsis for "Super Power"
As Supergirl is being packed away by special forces, she is carried away suddenly by Power Girl, who has been hoping to avoid ever meeting her other self, since she arrived in this reality. Unfortunately, they have both been poisoned, and she hopes that together, they can find the cure.
When she opens Supergirl's container, she is surprised by the girl's similarity in appearance to her - though this earth's Kara is much younger than she. Supergirl begins to wake, and as she reaches out for Power Girl's hand, their touch causes a sudden understanding. Though their histories are somewhat different, they are the same person, deep down. Supergirl realizes that though she was poisoned with Kryptonite, she is alive and still strong. They are interrupted, though, by attacks from the soldiers who want to reclaim her.
They fight side by side until suddenly the massive Appex falls from the sky and crushes Power Girl, announcing his intent to test Supergirl's power. He is surprised when Power Girl gets up, and counter-attacks. Angrily, Lex Luthor watches from afar, and warns that he didn't send Appex there to converse. Banding together, the two Karas turn on Appex, and punch him into the stratosphere.
Unfortunately, the effort causes the Kryptonite poisoning to resurface in Supergirl, and she begs Power Girl to take her to her sanctuary. Speeding under the sea to the sanctuary, thanks to their shared knowledge, Power Girl is surprised when it greets both of them by name. After passing Supergirl off to the sanctuary's medical robots, Kara investigates, realizing that it is Kryptonian in origin. With her costume mostly destroyed, Power Girl wishes aloud that she was better dressed, and the sanctuary answers her request by presenting her with a new costume.
Once she has it on, Supergirl appears, complimenting the costume's appearance on her. Though Supergirl is up and about, the poison remains in her system, and Power Girl assures her that they will find a cure together. Suddenly, though, the Sanctuary realizes that there are two Kara Zor-Els within it, and determines that one must be a clone. For the safety of the true Kara, Sanctuary decides that the clone must be destroyed.
