- Billy Batson: The original Captain Marvel, created by Fawcett Comics in The Golden Age of Comic Books as a Superman knockoff. Billy shouts the magic word "SHAZAM!" to call down magic lightning which transforms him into the World's Mightiest Mortal. Ironically, currently owned by Superman's creators DC Comics, though they had to title his books Shazam! due to rights conflicts with the other Captain Marvels listed (becoming the Trope Namer for I Am Not Shazam) and eventually changed his name to "Shazam" completely.
- The Adventures Of Captain Marvel, a 1940s film serial starring this version.
- Mar-Vell, created by Marvel Comics in the Sixties when the trademark on the "Shazam" version lapsed. Mar-Vell is a Human Alien who went native and defended Earth, until he was Killed Off for Real in the Eighties.
- Monica Rambeau, the next one from Marvel Comics. After gaining energy powers in a freak accident, she took up Mar-Vell's now-vacant title. She gave up the name once actual successors to Mar-Vell appeared, and has since gone by Photon, Pulsar, and Spectrum; though she's currently best known by her birth name.
- Genis-Vell, Phyla-Vell, Khn'nr, and Noh-Varr: A series of successors to Mar-Vell. Genis-Vell was Captain Marvel for about ten years from the mid-Nineties to the mid-Noughties, but none of the others had very long tenures. They're included on Mar-Vell's page.
- Carol Danvers, the current holder of the name. Originally a supporting character of Mar-Vell's, Carol Danvers eventually gained superpowers herself and became his Distaff Counterpart. After spending decades under different names (Ms. Marvel, Binary, Warbird), she became the latest Captain Marvel in 2012.
