Jane Doe

A "Jane Doe" is a placeholder name for those women whose identities are not identified. The name "John Doe" is used for men.

After a battle with the Brotherhood of Mutants, Ms. Marvel was put into a coma. Because no one knew her true identity was Carol Danvers, the Midtown Hospital classified her as a Jane Doe.

Years later, the X-Man Rogue visited Carol and told the attending doctor her real name.
