Superman / Batman #13

Supergirl takes center stage on Michael Turner's striking cover for this 2004 DC title, soaring high above the clouds in her blue-and-red costume with golden hair streaming behind her and fists clenched with unmistakable resolve. The combined Superman/Batman logo looming overhead reminds readers this series brings together the World's Finest, while the "Part Six of Six" designation means writer Jeph Loeb and artist Michael Turner are delivering the conclusion of "The Supergirl from Krypton" arc. It's a visually confident send-off to the storyline, with Turner's clean linework and Peter Steigerwald's vivid colors making this one of the more eye-catching covers in the series' run.
