Atop the World Trade Center, a ferocious battle rages between the Avengers and the Zodiac! When Aries throws Mantis off one of the 110-story towers, the tide takes a lethal turn! However, in spectacular style, the Vision dramatically saves Mantis from certain death! Several hours later Earth's Mightiest Heroes track the Zodiac, and for the third time in as many days, the Mighty Avengers throw down with the super-villains from the stars!
