Annette Bening's character in Supreme Intelligence, Bening was a holographic image plucked from Carol Danvers' mind, representing the face and form of a person Captain Marvel truly respected. Over the course of the movie, viewers learned that the inspiration was Dr. Mary Lawson, a brilliant research scientist who was secretly a rogue Kree operative on Earth called Mar-Vell.
The Kree agent Mar-Vell is a classic figure from the comics, created by Stan Lee and Gene Colan in 1967, and is originally a male. Indeed, directors Anna Boden and Ryan Fleck told Entertainment Weekly that they'd planned to do a comic-book-accurate version. They'd already started looking for a male actor to play the part when they decided to make a last-minute switch. It was Boden who came up with the idea of combining the Supreme Intelligence and Mar-Vell, streamlining the narrative. She approached Marvel, who immediately green-lit the approach.

In the comics, Mar-Vell inspired Carol Danvers to become a superhero; in fact, he was the first Captain Marvel, and Carol ultimately took up the codename in his honor years after his death. This is a fairly traditional comic book trope, with male heroes inspiring women to follow in their footsteps; particularly prominent examples include Supergirl and Batgirl. The MCU's gender-swap completely subverts this, although Bening's Mar-Vell still serves as Carol's inspiration. But, aside from the gender-swap, she's not so different to the comic book version.

Mar-Vell's Origin Story Is The Same In Captain Marvel
Introduced in Marvel Super-Heroes #12, Mar-Vell was a Kree scientist who was sent to Earth on a secret mission. Little by little, his interaction with humanity led to his realizing that the Kree weren't to be trusted. He betrayed the Kree in defense of his new people, and became a noted superhero on Earth. In a similar way, in Captain Marvel Annette Bening's character was indoctrinated from birth and spent half her life fighting the Kree's wars. But somehow she realized the truth - that the Skrull were not the villains but the victims - and she betrayed her own people in a desperate attempt to save the last survivors of the shapeshifting race. That quest led her to Earth, where she studied the Tesseract. There's a clear parallel between the comic book character and the MCU version, with both coming to reject the Kree and betray their own people.
Interestingly, Mar-Vell's comment - about having fought for the Kree for half her life - suggests her story has been going on for decades, if not a century or more. The MCU's version of the Kree are remarkably long-lived; a Kree blood transfusion is the reason Carol Danvers hasn't aged between 1995 and 2019, between Captain Marvel and Avengers: Endgame. Given that's the case, it's possible Mar-Vell has secretly been working against the Kree for a long time before her death. The untold story of Mar-Vell, hinted at in the movie, is a lengthy one.
Carol Danvers' Origin Keeps The Mar-Vell/Yon-Rogg Rivalry
In the comics, one of Mar-Vell's greatest enemies is a fellow Kree warrior named Carol Danvers' superhero origin story, and a fascinating one.

On the face of it, the rivalry between Yon-Rogg and Mar-Vell has been erased in the MCU, but that's not necessarily the case; bearing in mind the lengths of Kree lives, it's entirely possible that the fateful clash between Yon-Rogg and Mar-Vell on Earth was the end of a bitter feud. Certainly, Yon-Rogg must have been monitoring Mar-Vell for some time in order to know that her prototype was complete and being tested. All that's different is who emerged victoriously - to begin with.

Mar-Vell Could Have Interacted With Other MCU Characters As Well
The comic book version of Mar-Vell is an important figure, best ed for Jim Starlin's unforgettable graphic novel The Death of Captain Marvel. That saw Mar-Vell face a surprising death for a superhero: he didn't die in combat, nor did he perish saving the world; instead, he died because of cancer. The assembled heroes of the Marvel Universe gathered at his deathbed, giving a true sense that Mar-Vell had become a champion of Earth. The MCU version of Mar-Vell will never have that kind of impact; she was murdered by Yon-Rogg in 1989, nearly 20 years before Tony Stark would suit up as Iron Man.
But does that really mean Mar-Vell had no impact on the wider MCU? It's almost certain she crossed paths with Howard Stark who according to Project P.E.G.A.S.U.S. for a time, likely on the Tesseract Project. In fact, it wouldn't be surprising if Mar-Vell had even told Howard the truth about her identity and purpose; it would surely be a lot easier to steal the Tesseract if she had a high-ranking S.H.I.E.L.D. operative on her side. That means Mar-Vell could have encountered other S.H.I.E.L.D. figures at the time too, such as Peggy Carter. Presuming she'd become a respected scientist, Dr. Wendy Lawson could have potentially met Dr. Hank Pym as well. Mar-Vell may have had a far greater impact on the MCU than Captain Marvel shows.
Carol Danvers Continues Mar-Vell's Legacy
The greatest similarity between the comic book and MCU versions of Mar-Vell, though, is their legacy. In the comics, Mar-Vell's legacy lived on through Carol Danvers, who attempted to redeem the Hala Star as a symbol of hope and justice. She has served as one of Earth's mightiest defenders, even commanding S.W.O.R.D., an organization dedicated to protecting the Earth from alien attack. Although Carol operated under the "Ms. Marvel" codename for years, she eventually became "Captain Marvel" in honor of the extraterrestrial hero who had inspired her.

In almost exactly the same way, the MCU version of Carol Danvers embodies Mar-Vell's legacy. At the Guardians of the Galaxy, in 2014 the Kree finally signed a peace treaty with Xandar; Carol Danvers was potentially involved in that. If so, she's embodied Mar-Vell's wildest dreams, and has brought peace to the galaxy - in honor of Dr. Wendy Lawson, a.k.a. Mar-Vell.
