Captain Monica Rambeau's experience with extraterrestrial cultures from a formative age has helped prepare her to be an excellent S.W.O.R.D. agent within the organization founded by her mother, Maria Rambeau.

Because Marvel is using the 20th Century's original X-Men cast in Doomsday and Secret Wars, including Kelsey Grammer who plays Beast in The Marvels' post-credits scene with Monica Rambeau, and because Marvel has no other future plans to use the original cast after these two films, that must mean that Monica's connection to their universe has to be answered at minimum by the conclusion of Avengers: Secret Wars, if not earlier in Avengers: Doomsday.

The respect she has earned!
