Tony Stark is known for his creative inventions, with perhaps the Iron Man armor being the biggest of them all. However, he sets out to top himself in A.X.E.: Judgment Day, a crossover event between the Avengers, X-Men, and Eternals. A war has broken out between the X-Men and Eternals, with Earth's Mightiest Heroes caught in the middle. The second issue finds Iron Man in an unlikely team-up with the heroic members of the Eternals and an X-Men villain, as they race to end the war before it causes irrevocable damage. Unfortunately, their impressive creation could result in Earth's downfall and reveals how Judgment Day gets its appropriate title.
