Supergirl and the Legion of Super-Heroes #18

Supergirl steps front and center on Barry Kitson's cover, confident in her classic blue-and-red costume as a crowd of Legion members fans out behind her — and the bold question "Who's the Boss?" makes the power dynamic immediately intriguing. Mark Waid and Kitson's 2006 run continues to blend the grandeur of the 30th century with fresh character dynamics, and this issue looks poised to put Supergirl's leadership — or lack thereof — squarely in the spotlight. A great chapter in one of DC's most team-focused titles of the era.
