Carol Danvers is not the only captain Marvel of the Marvel Comic Book Universe. There are 11 more Captain Marvels the Marvel Cinematic Universe would never tell you about.

Wolverine was chosen to travel back in time to kill Hak Pym before he could create Ultron. When he travelled back to the future after doing his job, he saw another bleak future where Morgan le Fay had taken over the world. In this new world, Janet Van Dyne became the new Captain Marvel using her size changing powers.
When the Skrulls were planning Secret Invasion, they tried their best to create perfect duplicates for all the heroes they planned to replace. The hardest to replicate was Captain Marvel. His energy manipulation powers and his Kree physiology made it very hard for the Skrulls to come up with a perfect subject. They finally succeeded in their 97th attempt. After Secret Invasion failed, the 96th test subject sprang back to life. He was manipulated by Mystique into attacking a group of cult worshippers until he broke free and self-detonated in a radioactive blast.
Rogue once absorbed all of Captain Marvel’s powers decades ago. This was before Carol Danvers became captain Marvel, then operating under the codename Ms. Marvel.

Carol ended up with Rogue’s power absorption while Rogue permanently absorbed Carol’s energy manipulation powers. She was later given Binary abilities by the Brood. Rogue became that world’s Captain Marvel.
