After the Credits
There is an extra scene after the credits of Avengers: Infinity War.
In the extra scene, Nick Fury (Samuel L. Jackson) in shown driving through the New York City fallout caused by the battle with Thanos. He then receives word of the Wakanda attack just as a car in front of him crashes. When he and S.H.I.E.L.D agent, Maria Hill (Cobie Smulders), get out to investigate, no occupants are found in the car.
A helicopter then crashes into a building as Hill is turned into ash. Fury yells, “Code Red!” while dashing back to his vehicle. Fury picks up a communication device, activates it, and then turns to ash himself.
The device falls to the ground and a star symbol appears on the screen teasing Captain Marvel.
