After resolving Kamran's crisis and getting his superhero name, Kamala is resting on her bed. Her bracelet activates, and Kamala disappears into her closet. Instead of her, Carol Danvers (Brie Larson) appears in a new costume. Captain Marvel doesn't understand how she ended up on earth and is amazed at the number of posters in Kamala's room. Then the message appears announcing that Ms. Marvel will return to The Marvels.
This is yet another clue that Kamala's bracelet is the MCU version of the Negabande, created in 1969 by Archie Goodwin and Don Heck in Captain Marvel # 16. Teleportation is one of the powers of the Negabande. Recently in the comics, the Negabande have been turned into the wedding rings of Wiccan (Wanda's son) and Hulking. All episodes of Ms. Marvel are available on Disney +.
