Some super-teams just rub other super-teams the wrong way. So it is in the collection of TWO epic showdowns for the Agents of Atlas! When Venus goes missing, the team hopes to use the X-Men's technological wonder, Cerebra, to track her down. But they didn't say "please," and Cyclops, Wolverine and their band of merry mutants refuse to stand for such poor manners! Then, an unknown entity manipulates the time-space continuum, bringing the classic Avengers into the present, and these Avengers don't take kindly to time traveling against their will. Neither does the atomic wild card, the Incredible Hulk! The Agents will have to return everyone to their own time if they hope to preserve the future! Collecting X-MEN VS. AGENTS OF ATLAS #1-2 and AVENGERS VS. ATLAS #1-4.
