"Avengers: Infinity War" is reportedly going to feature a new Marvel character's debut. However, it is also expected that the X-Men will not be joining the Marvel Cinematic Universe in the near future.

According to Yibada, the directors of "Captain America: Civil War," Anthony and Joe Russo, have divulged some new details on this upcoming "Avengers" movie, teasing fans about the newest character to be added to the Marvel Cinematic Universe. Of course, while they gave no mention about the character's identity, a lot of speculations say that this character will most likely be Carol Danvers, also known as Captain Marvel. This character will be played by the actress Brie Larson, as announced during the 2016 San Diego Comic-Con event.

Furthermore, Anthony Russo said that they are in a tight spot, trying to convey the "Avengers: Infinity War" story without the use of pre-existing characters. His brother, Joe, even went so far as to say that Anthony might have died from the exhaustion of just thinking about it. Regardless, the brothers gave their word that the new character will show up any time soon.

Meanwhile, the X-Men's appearance in the Marvel Cinematic Universe still remains far-fetched, since the rumors about the possible inclusion of the Children of the Atom has been officially debunked by the Russo Brothers. The ComicBook points out that Joe Russo clarified the misunderstanding by saying that there are currently no talks about getting the X-Men into the MCU. 

Regardless, after Marvel's success in bringing Spider-Man to the MCU with the help of Sony, a lot of fans say that it is only a matter of time before the Children of the Atom as well as the famed Fantastic Four into the same universe. Also, with Hugh Jackman retiring as Wolverine's character, the Russo Brothers also hopes to bring Wolverine to the MCU as well.
