There's mounting anticipation within the Marvel Cinematic Universe as hints suggest the X-Men might be introduced in the upcoming MCU film, "The Marvels." Marvel Studios President Kevin Feige, in an interview with Entertainment Tonight, hinted at the possibility of the X-Men's live-action debut happening 'perhaps soon,' referencing an animated series revival and the rich history of the X-Men characters.

In the latest trailer for "The Marvels," there are potential clues that have fueled fan theories about the inclusion of the X-Men. Monica Rambeau mentions a "different reality bleeding into ours," and a trailer displayed the phrase "What Comes Next" with all but the letter "X" fading away, further driving speculation. Additionally, a symbol that resembles the X-Men logo and a character fans have likened to Storm, a member of the X-Men, were seen in the trailer, however Feige remained non-committal when probed about these teases.

Amidst these rumors, the discussion about returning deceased Avengers characters such as Tony Stark/Iron Man and Natasha Romanoff/Black Widow was brought up in another interview with Feige, who confirmed a new project with Scarlett Johansson while denying plans for reviving fallen Avengers. As theories and speculation continue, fans eagerly await any official confirmation of the X-Men's arrival in the Marvel Cinematic Universe.
