Synopsis
A new Cancer assembles a new version of the criminal group Zodiac, claiming to have a source of power for them. Meanwhile the Avengers gather to announce the opening of the new Avengers Tower.
Hulk sees an army convoy in the desert attacked by a water being. He leaps in to help the army but of course they think he's in league with the bad guy. During the ensuing 3-way battle the villain briefly loses his water power, revealing the new Aquarius within. Eventually Aquarius makes off with something the convoy was transporting that he has ripped out of its container. Hulk leaves with an insignia that fell from the villain's suit, and Gen'l Whedon calls in the Avengers.
Black Widow and Hawkeye are investigating a supposed nuclear arms deal in Latveria which turns out to be for a single large container. They steal the truck carrying the device, pursued by a large minotaur who is the new Taurus. But they too have called in more Avengers, and Iron Man and Thor turn up. However the empowered minotaur is easily their match, and stops Clint and Natasha's escape by throwing Thor at their truck.
