Captain Marvel best friend daughter is a fictional character in the Marvel Cinematic Universe. She is the best friend of Captain Marvel and has a very interesting backstory. She was a part of the notorious Cortex corporation which freed Inhumans from a distant planet. This villain was defeated in the Avengers movie.
Monica and Carol were very close friends, and Monica is one of the most important people in Carol’s life. She may have never visited Maria in her last years, since she was busy dealing with Thanos’ snap of the universe. If so, Monica’s death could have been a surprise to Carol.
Monica went by various names while growing up, including Pulsar and Spectrum. Her parents were Carol and Maria Rambeau. She was a capable flier who trained in the art of piloting. She also became a member of the Sentient Weapon Observation Response Division (SWORD), a space-based organization that protects Earth from threats.
Monica Rambeau’s comic book history goes back to 1982, when she first appeared in “The Amazing Spider-Man Annual” No. 16. She later joined the Avengers as the first Black woman in the Marvel Universe. She eventually gave up her superhero name and adopted a new one, Photon, from her mother’s fighter pilot callsign. She has also used the superhero name Pulsar and Spectrum.
