Mar-Vell

"The wars are bigger than you know."

- Mar-Vell to Carol Danvers

Mar-Vell, also known as Wendy Lawson, was a Kree scientist who used to live on Earth where she worked with the United States Air Force in the framework of Project P.E.G.A.S.U.S.. Together with Carol Danvers and Maria Rambeau, Mar-Vell worked on harnessing the energy of the Tesseract to create a Light-Speed Engine which according to her, would help end the Kree-Skrull War. Despite being a Kree herself, Mar-Vell intended to offer the technology to the Skrulls so they could relocate far from the Kree. However, while putting the engine on trial, Mar-Vell and Danvers were attacked by the Kree Starforce, which caused them to crash, and Mar-Vell was eventually shot by Yon-Rogg while trying to destroy the engine so the Kree could not control it.

Death
"I spent half my life fighting a shameful war. Now get out of here before you give me any more regrets. Just remember the coordinates, okay? You gotta save them without me."

- Mar-Vell to Carol Danvers

While testing the Light-Speed Engine with Carol Danvers, Mar-Vell was found by Yon-Rogg and Minn-Erva, two Kree soldiers of Starforce who shot the plane out of the sky. After crash-landing, Mar-Vell told Danvers the truth about who she was and her mission on Earth. She insisted on destroying the energy core of the engine so that the Kree could not get it. Before she could do so, Yon-Rogg shot her in the chest, killing her.

Legacy
After Mar-Vell's death, Carol Danvers would eventually carry on her mission of helping the Skrulls find a new place to live and let them get away from the Kree Empire.

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."
 * Elisabeth P. Carpenter and Ingrid Kleinig were stunt doubles for Annette Bening in the role of Mar-Vell.
