Creation Story
Carol Danvers has three first-appearance keys representing three identity stages.
Marvel Super-Heroes #13 (March 1968) introduces Carol as a U.S. Air Force officer in the Mar-Vell Captain Marvel series. Roy Thomas wrote; Gene Colan pencilled. Carol is a civilian at this stage with no powers and no superhero identity. The framework establishes her relationship with Mar-Vell, the Kree military officer who is the original Captain Marvel.
Captain Marvel #18 (November 1969) provides Carol’s power origin: caught in the explosion of the Kree Psyche-Magnitron, she gains Kree-derived super-strength, flight, and energy projection. The framework was a setup for her eventual superhero debut, which arrived eight years later.
Ms. Marvel #1 (January 1977) is Carol’s first superhero identity. Gerry Conway wrote; John Buscema pencilled. The 23-issue run through 1979 establishes the Ms. Marvel framework that has been Carol’s primary superhero identity for most of her publishing history. The title was cancelled in 1979 but the character remained continuously active across Avengers and X-Men titles.
The Captain Marvel mantle
Captain Marvel #1 (September 2012) by Kelly Sue DeConnick and Dexter Soy is the most consequential modern Carol Danvers book. DeConnick had Carol assume the Captain Marvel name after thirty years of the mantle being held in reserve following Mar-Vell’s death. The DeConnick run modernized Carol’s voice, established her current solo-publishing framework, and provided the foundation for Brie Larson’s 2019 MCU performance.
The DeConnick Carol has continued across multiple subsequent Marvel runs. The Captain Marvel name is now firmly attached to Carol; Mar-Vell appears occasionally in alternate-reality and time-travel stories but Carol is the modern Captain Marvel.
Collector context
Marvel Super-Heroes #13 (Carol Danvers civilian debut) is the technical first-appearance key. High-grade CGC 9.0+ copies have crossed $5,000 at auction.
Ms. Marvel #1 (1977) is the first superhero identity and is widely traded as a Carol-Danvers-as-superhero key. Captain Marvel #1 (2012) is the modern key and has spiked in value with each MCU appearance. All three are collected together by serious Carol Danvers collectors.
Marvel Super-Heroes #12 (December 1967) is the first Mar-Vell appearance and a Silver Age Marvel key in its own right; it predates Carol’s first appearance by three months and is the foundational Captain Marvel debut for either character.
