Warning! This story deals with mature themes.
The Marvels or in any future films.
Carol Danvers is ultimately a tragic character who repeatedly suffers at the hands of her enemies —and even her own teammates. In the highly controversial Avengers #200 in 1980, Carol (then going by Ms. Marvel) is sexually assaulted and impregnated by an alien who gives birth to itself. It mind-controls Carol into falling in love and leaving the team with the being...all while her fellow Avengers do nothing to help her (they even applaud the decision!). When the mind control fades, Carol is justifiably furious at her teammates for their inaction. This event, combined with Rogue stealing her powers and memories, results in Carol feeling lost and abandoned, and she gravitates to alcohol.
Carol frequented the bar in the Avengers mansion during the '90s, and it unfortunately impacted her performance in battles. Iron Man noticed this — he had previously battled his own addiction to alcohol in the famous Demon in a Bottle storyline — but his attempts to help Carol with her addiction failed. Every other attempt from her fellow Avengers to talk to Carol was met with denial and hostility. After a battle ended with Carol inadvertently injuring a teammate while drunk, she was deemed a liability and was voted off the Avengers entirely.
Carol would eventually it her alcoholism, overcome her addiction and even attend regular AA meetings with Tony Stark. Though this is a not-insignificant aspect of her character, it's doubtful that Disney would allow such a storyline in a future film. An early draft of Iron Man 3 featured elements from the Demon in a Bottle comic, but were heavily discouraged by Disney, who did not wish to paint Tony Stark as an alcoholic in reaction to his popularity with young fans. Since Captain Marvel is a role model and a wildly popular character in her own right, it's likely Carol Danvers will see the same oversight from the company.
This is not to say that Carol's appearance in The Marvels will be entirely without a human element or identifiable struggle. 2019's Captain Marvel's main villain was institutionalized sexism — Carol is continuously told not to use her powers, forcing her to fight at a disadvantage because Yon-Rogg would no longer be able to control her. The fact that the final fight between the two is so lopsided showcases just how much Yon-Rogg and the Kree society had been holding Carol back. Fans should watch for this theme to continue in future Captain Marvel comics and of course, her feature film The Marvels debuting in 2022.
