Captain Marvel: The First Avenger stars Teyonah Parris as Geraldine, an adult version of Monica Rambeau from the first season. In the episode “WandaVision”, Geraldine is shown delivering her twins Billy and Tommy with the help of Vision. Despite the fact that she is pregnant, Geraldine’s mother Wanda is annoyed with her and begins to question the validity of her pregnancy.
In Captain Marvel, Geraldine’s mother, Monica, is a former best friend of Carol Danvers, the character’s first human appearance. However, she has a mysterious past, so it is unclear what her role is in the series. In the comics, she is the young girl Monica Rambeau, who breaks the illusions of Wanda. While the character of Monica is largely unknown, her role in the film remains unclear.
In the television series, Geraldine’s mother died from cancer three years ago. Her parents’ death was a surprise to them, so they figured she must have had some sort of premonition. The doctor told her that she was going through chemotherapy at the time of the movie. The two women then met again in the comics. The series continues to grow and the new episodes are expected to feature more recurring characters.
In the comics, Geraldine was first introduced in the second episode of the show, starring Teyonah Parris. The actress was introduced in the role of Monica Rambeau, a child-like version of Monica. The character was later revealed to be pregnant and to be a grown-up. In the upcoming third episode, she will be revealed to be the daughter of Maria Rambeau, played by Akira Akbar in Captain Marvel.
