Captain Marvel seemingly had the same history as her Earth-616 counterpart, until she was infected with the "Spider-Virus."[1]
She was one of the former superheroes who were sent to trap Resistance fighters at Horizon Labs. While the trap worked, the resistance fell into it on purpose; to rewrite the spiders DNA to remove Spider-Queen's control over them. For Carol, she was given Morbius' serum and transformed into a Vampire.[1] After realizing her transformation had given her a craving for blood, her longtime friend Spider-Woman revealed that the Resistance members had donated their blood to ensure those cured with the Morbius serum would have an ample supply to drink.[2]
Joining the resistance, she took part in their assault on The Queen's Castle.[3] Captain Marvel watched as Flash and his symbiote sacrificed themselves to get Spider-Queen in position to get her killed by Stegron and his Dinosaurs.[4]
Days later, she became involved in the rebuilding of Avengers Tower and was present when Dino-Thor, the Thor Corps representative of the Valley of Flame, came on behalf of God Emperor Doom to pick a new baron of Spider-Island. Carol and the rest of the reformed Avengers all voted Spider-Man.[4]
