During the Credits
There are image sequences from the film followed by an extra scene during the credits of Captain Marvel.
The first extra scene begins by showing the pager that Captain Marvel upgraded and gave back to Nick Fury (the same one that Fury uses to call Captain Marvel in the post-credits scene of Infinity War).
The pager is hooked up to some external charging equipment, but the screen still goes black, indicating that the unit seems to have lost power. As the camera pans, other screens with messages about millions of people missing are revealed (again referring to the events of Infinity War).
Black Widow, Bruce Banner, and Captain America are then revealed to be the ones trying to fix the pager. They have a brief discussion about how they haven’t been able to trace the pager’s signal and as they turn around, Captain Marvel shows up behind them asking, “Where is Fury?”
After the Credits
There is a stinger after the credits of Captain Marvel.
In the scene at the very end of the credits, Goose the cat is shown on Nick Fury’s desk coughing up what seems to be a hairball. It’s then revealed that it isn’t a hairball at all and instead the Tesseract that he swallowed near the end of the movie and that was previously in possession of S.H.I.E.L.D.
