The X-Men and the Avengers have a lot of problems with each other ideologically. While the Avengers talk a big game about saving everyone, they have often looked the other way when it comes to mutants being targeted by the government the Avengers is usually allied with. The X-Men take exception to the Avengers’ ignorance of mutant affairs, and this has led to some battles between the two. Over the years, the X-Men and the Avengers have had some battles against each other, and these five are the most memorable.
5) X-Men (Vol. 1) #9

The first crossover between the X-Men and the Avengers came in X-Men (Vol. 1) #9. This story revealed why Professor X was paralyzed as the X-Men hunted for the alien who dropped a cave on him in the past, Lucifer. However, the Avengers were out and about as well, following Thor’s hammer, which had sensed a disturbance. This caused the two teams to tangle with each other when they met up in a Bavarian village. Obviously, the Avengers were able to get the upper hand, but neither side really won the fight. This fight showed how easy it was for the Avengers to decide to attack the X-Men, and it would be far from the last time that two teams clashed.
4) Ultimate War

We’ve gotten a new Ultimate Marvel Universe, and many of the fans who have been around for both think the new one is better. However, the old Ultimate Universe did have its highlights, and one of those was Ultimate War #1-4. This miniseries spun out of the events of Ultimate X-Men, as it was revealed that instead of killing Magneto, Professor X had merely erased most of his memories to give him a chance to live a normal life. The Ultimates, the Ultimate Universe version of the Avengers, were called in by SHIELD and the two teams ended up fighting it out. The Ultimates basically won this fight; the X-Men were able to escape and stay out of jail, but they had to go underground because the Ultimates were still hunting for them. A lot of the old Ultimate Universe didn’t age well, but if you can find this one from Mark Millar and Chris Bachalo, you should check it out. It’s one of the best Avengers/X-Men battles.
