|Appeared in||Captain Marvel|
Mar-Vell abandoned the Kree when she discovered that the Skrulls were refugees in need of a new home. She stowed away on Earth with a group of Skrull refugees in her Laboratory that was in orbit. On Earth, Mar-Vell took the name Wendy Lawson and began to work for Project Pegasus to try and develop a Light-Speed Engine in a bid to help the Skrulls.
Lawson came to work with Carol Danvers and Maria Rambeau who were the test pilots for her experimental aircrafts as they weren't allowed to fly combat due to their gender. When Lawson decided it was time to pilot the Light-Speed Engine to the Skrulls, Carol insisted that she help but they were attacked by a Kree vessel which shot their engines. Carol crash landed the plane but Lawson was injured, bleeding blue blood. She revealed her true identity to Carol and told her that the Light-Speed Engine had to be destroyed so that the Kree couldn't take it. She took out a blaster and aimed at the engine but was shot dead by Yon-Rogg.
Carol finished the job and destroyed the engine but absorbed all of the energy into her body. Yon-Rogg took her to Hala and gave her a blood transfusion to make her believe she is a Kree. From that point, when Carol went to the Supreme Intelligence, it took the form of Lawson even though Carol couldn't remember who she was.

Behind the scenes
- Kevin Feige stated the decision to cast Annette Bening came very late, as they were still intending to cast a male actor shortly before filming began. Feige attributed Bening's casting to Anna Boden's decision to make the Supreme Intelligence take on Mar-Vell's appearance, stating "it was like, 'Oh, of course! That's perfect!' And we stopped looking for another actor."
- In the comics, Mar-Vell was a Kree male and Captain of the Imperial Kree Army war hero. Arriving at Earth, Mar-Vell disguised himself as Walter Lawson, researching the human race. Eventually, Mar-Vell turned against Kree Empire and became the original Captain Marvel.
- Mar-Vell is the fourth character in the Marvel Cinematic Universe to be depicted as a different gender from their counterpart in the comics, following Jeri Hogarth, the Ancient One and Ghost.
