The upcoming Marvel Cinematic Universe film "Avengers: Doomsday" is slated to be the biggest crossover event yet, and its trailer hints at significant conflict between the Avengers and the X-Men. While the film's exact plot remains under wraps, the prospect of these two iconic teams squaring off against each other before uniting against a common foe has drawn attention to their limited history of direct confrontations in the comics.

Historically, the X-Men have often operated in a distinct corner of the Marvel Universe, with interactions with other major teams like the Avengers being relatively infrequent outside of specific crossover events. This separation has resulted in fewer opportunities for large-scale team-on-team battles. However, several notable exceptions exist, offering a glimpse into their past encounters.

Early Encounters

The first documented clash occurred in "Enter... the Avengers!" (X-Men v1 #9) in 1964. This early Silver Age story depicted the original five X-Men and Professor Xavier confronting one of Xavier's old foes. The Avengers inadvertently became involved, leading to a confrontation driven by the era's often whimsical comic logic. The power disparity was significant; the classic Avengers lineup, featuring Thor, Iron Man, Giant-Man, the Wasp, and Captain America, held a considerable advantage over the X-Men. This issue also notably featured a considerably less powerful Silver Age Jean Grey, a stark contrast to her later cosmic-level abilities.

Another significant, albeit one-sided, encounter took place during the original "Marvel Super Heroes Secret Wars" in 1984. Created to promote a line of action figures, this massive crossover saw numerous heroes and villains brought to a planet called Battleworld and compelled to fight by an alien entity. It has been suggested that then-Marvel Editor-in-Chief Jim Shooter may have used the event to express frustrations with the X-Men. During "Secret Wars," the X-Men faced considerable defeats, including a sound thrashing by Spider-Man in issue #3 and another by the Wasp in issue #4. These outcomes have been attributed by some to the writer's narrative leanings rather than a true power mismatch.

The 1987 Miniseries and "Avengers vs. X-Men"

In 1987, the miniseries "The X-Men vs. the Avengers" explored a more complex scenario, set against the backdrop of the Cold War and a Soviet plot. The story attempted to reconcile Magneto's recent turn towards heroism with his past villainous actions, which included the destruction of a Siberian city and the sinking of a Soviet submarine. The plot pitted the X-Men and Avengers against each other as the latter sought to protect Magneto from assassination. This miniseries, while featuring significant talent like Roger Stern and Marc Silvestri, experienced a shift in its creative team for the final issue, resulting in a less cohesive conclusion.

More recently, the 2012 event "Avengers vs. X-Men" (AVX) presented a major conflict. The event revolved around the mutant Hope Summers, prophesied to be a savior for mutants, and the cosmic Phoenix Force hurtling towards Earth. When the Avengers, led by Captain America, sought to take Hope into protective custody, Cyclops refused, igniting a full-scale war. AVX delved into the seven years of comic history leading up to the conflict, and while the main series focused on the Phoenix entity's narrative, many spin-off issues delivered highly anticipated hero-on-hero battles, often embraced with a deliberate sense of spectacle.

Historical Record

Across these confrontations, the X-Men's win-loss record against the Avengers is largely unfavorable. Counting direct engagements, the X-Men hold approximately a 1-5 record. If the Spider-Man fight from "Secret Wars" is excluded due to his non-Avengers status at the time, the record shifts to 1-4. Notably, simulated battles like the "Teen Avengers" fight in "New Mutants Annual #3" are typically not counted. The X-Men's sole decisive victory came during "Avengers vs. X-Men," where five Phoenix-empowered X-Men fought against the entire Avengers roster. This historical imbalance is often attributed to the Avengers typically fielding their most powerful members, such as Thor and Monica Rambeau, when facing the X-Men.

As "Avengers: Doomsday" prepares for its December 18 release, the film's narrative may present a different outcome, but based on their comic book history, the odds have historically favored Earth's Mightiest Heroes.
