8HOW DID SHE LOSE HER POWERS?
Captain Marvel has a lot of enemies and allies, but there is one person that happens to be a superhero in Marvel Comics that shares one of the darkest moments of Carol Danvers' past. As Ms. Marvel, Carol went up against some mutant villains in Mystique, Destiny, and Rogue.
During the fight, Rogue used her mutant abilities to suck the powers out of Carol and went way too far. Rogue kept draining Carol and ended up putting her into a catatonic stage, draining her of almost all her powers, and stole her memories as well. It drove both women to the edge of sanity by the time all was said and done.
