Since Captain America: Civil War, hints have been made that The Marvels will introduce a much-needed MCU team dynamic.
A classic team dynamic in any narrative is a youthful member learning from an experienced mentor.
This is especially effective in superhero tales, as major franchises such as Marvel and DC now profit from superhero team-up films.
The MCU hinted at this dynamic with Tom Holland's Spider-Man in Civil War, but The Marvels has the potential to fully exploit this arrangement.
Peter Parker was introduced to the Marvel Cinematic Universe in Captain America: Civil War as Tony Stark's protégé.
Tony takes Peter to his first superhero combat, where he interacts with the vastly more experienced Avengers, while Peter is still learning how to use his new superpowers.
Due to Peter's rejection of the Avengers and his temporary demise after the Snap, which led to Iron Man's death shortly after Parker's return,
this opportunity was never completely exploited. As a result, the MCU has never truly explored a younger hero dynamic prevalent in the comics,
