When Fury gets a call from the real Coulson, who he left back in the Blockbuster parking lot, he realizes that the Coulson sitting next to him is a Skrull impostor. A fight ensues, but the Skrull is killed when Fury crashes his car into oncoming traffic.

Project P.E.G.A.S.U.S. was a joint project between S.H.I.E.L.D., NASA, and the United States Air Force to study the Tesseract, a crystalline cube-shaped containment vessel for one of six Infinity Stones that predate the universe and possess unlimited energy. In the 1980s, project leader Wendy Lawson, who was actually a Kree named Mar-Vell, used the Tesseract's energy to create the light-speed engine.

Although she has no memory of her former life, Vers was formerly Carol Danvers, a United States Air Force pilot who tested Lawson's light-speed engine.

Coulson corners the two fugitives in a stairwell, but trusting Fury implicitly, he allows them to escape.

Monica calls Danvers "Auntie Carol," while Danvers nicknames her "Lieutenant Trouble."

Maria Rambeau, a single mother and former U.S. Air Force pilot, was Carol's best friend. After the two are reunited, Carol begins to remember her former life.

CAROL: Your blood. It's ... it's blue.
MAR-VELL: Yeah, but ... ahh ... how's my hair?

While testing the light-speed engine with Carol, Mar-Vell is finally tracked down by Yon-Rogg and Minn-Erva who shoot the plane out of the sky.

She obtained cosmic powers upon being exposed to the energy of the Tesseract via the destruction of the light-speed engine.

Before the mission to save the Skrulls, Carol decides she can no longer wear Kree colors. Monica helps her choose the colors of the outfit she will later use as Captain Marvel.
