Supergirl Vol.5 (Inglés) 05 Variant Cvr

On the surface of the Moon, the real Supergirl and her evil doppelgänger square off against one another. Dark Supergirl taunts Kara, claiming her father Zor-El hated his brother and sent her to kill her own cousin. Supergirl retorts she's just lying and pounces. As they trade blows and Dark Supergirl keeps taunting Kara, the JLA turn up, regrouped and ready to fight, but Dark Supergirl flies off into space. Supergirl tells Martian Manhunter to read her mind and "warn him they're coming" before pursuing.
