As seen in the Captain Marvel article, that name has been applied to various characters in American ComicBook history. This article is about the ones created by Creator/MarvelComics.

During the [[TheSixties 1960s]], writer Creator/StanLee noticed that the name's trademark from [[{{ComicBook/Shazam}} the Fawcett Comics character]] was available again, and decided that Marvel should own it (Marvel Comics, Captain Marvel... makes sense, right?). So he created a new superhero named that, one quite different from the previous ones. The new character first appeared in ''"Marvel Super-Heroes''" #12 (December, 1967). Given the value of the name to DC and the utter obscurity of the Marvel version of the character, you'd think Marvel would cash in and make a mint selling the name back to DC at an enormous profit... except for the fact that he's called "Captain Marvel" and they're called "Marvel Comics" and you just can't let that kind of synchronicity slip away from you.

This "Captain Marvel" was an alien (from the Kree, a race that looked ''[[HumanAliens exactly]]'' [[HumanAliens like humans]] except for a [[RubberForeheadAliens blue-skinned minority]] that rules them.) His name actually ''was'' Mar-Vell and he ''was'' a captain in the Kree army. He came to Earth as part of mission to investigate Earth's space technology achievements (later [[JustifiedTrope justified]] by saying that Earth was located near a strategically important space warp.) Mar-Vell is sent to Earth while being monitored from orbit by the rest of his crew, which included his girlfriend Una and his superior, Colonel Yon-Rogg. Mar-Vell discovers he's [[ContrivedCoincidence the exact lookalike of an American senator]], who has just been murdered, so he takes over his identity to further his mission.

However, it turns out that Yon-Rogg secretly ''hated'' Mar-Vell, mostly because he wanted Una for himself. So he tries to have Mar-Vell killed. This forces Marvel (who has SuperStrength due to coming from a planet with higher gravity) to fight openly while wearing his Kree uniform, which caused people to mistake him for a new superhero called "Captain Marvel". He also became a target of a larger power struggle within the Kree government.

The betrayal from his own people (and the eventual death of Una) leads Mar-Vell to adopt Earth (and the name Captain Marvel) as his own. He had a brief relationship with Carol Danvers, a NASA security agent, who later becomes a superhero herself (MsMarvel). He gains new powers from an Earth scientist, and later, from The Supreme Intelligence, a supercomputer who is the Kree's true ruler. He also gained his more famous, red-and-blue costume from it.

For a period of time, Marvel found himself accidentally "merged" with teenage singer Rick Jones (the same kid who was involved in the ComicBook/IncredibleHulk's origin) so that only one of them could exist in the universe, with the other one stuck in the [[AnotherDimension dimension]] called the [[AntiMatter Negative Zone]] until the one on Earth struck together his "nega-bands" bracelets, causing them to switch places. (Writer RoyThomas has admitted that this was done as a nod to the original Captain Marvel, who was a child who could turn into an adult superhero.) It was later revealed that this was ThePlan of the Supreme Intelligence, who was really a MagnificentBastard whose ultimate goal was to jumpstart the evolutionary potential of the Kree race via Rick Jones's genes. Eventually, Marvel finds a way to bring back Rick from the Zone and they resume their lives.

The ''"Captain Marvel"'' magazine lasted for 62 issues (May, 1968-May, 1979). Tragically, Marvel didn't live long after his series was cancelled. In a very rare case of a comic book character being KilledOffForReal, he died from a cancer he got from exposure to nerve gas during one of his adventures. His death was covered ''The Death Of Captain Marvel'' (''Marvel Graphic Novel'' #1, April 1982, written and illustrated by Jim Starlin), and Mar-Vell's death is universally considered one of the most touching, well-written and dignified in the history of comics.

!!Monica Rambeau
To keep the trademark over the character's name (especially given that Creator/DCComics had since gained ownership of the original Captain Marvel character) Marvel Comics later created a new character who had ''nothing'' to do with the first, an African American cargo ship captain and harbor patrol lieutenant with the power to turn herself into PureEnergy. Monica first appeared in ''"Amazing Spider-Man Annual"'' #16 (1982), created by Roger Stern and John Romita, Jr. She would soon become a member of ComicBook/TheAvengers.

Monica was regularly featured in ''"Avengers"'' vol. 1 #227-294 (January, 1983 - August, 1988). With most of her appearances written by Roger Stern. She has had several subsequent appearances among their ranks, typically in storylines involving reserve members called back to action, not as one of the regulars. She also starred in two one-shot ''"Captain Marvel''" publications, one in 1989 and the second in 1994. She has not been forgotten though as she has since had appearances as a member of {{Nextwave}} and the Marvel Divas, and is currently featured as a major character in the 2013 ''Mighty Avengers'' relaunch. She changes her codename a few times (the first two changes were as a direct result of Genis-Vell), most recently taking the name Spectrum.

!!Genis-Vell
In ''"ComicBook/SilverSurfer Annual"'' #6 (1993), a new character, calling himself [[LegacyCharacter "Legacy"]] was introduced. Created by Ron Marz and Ron Lim. He was Genis-Vell, the son of Mar-Vell, created via cloning by Mar-Vell's last lover, Elysius, one of the [[{{Immortality}} Eternals]] of Titan (Saturn's largest moon.) He would later take over his father's identity and become the new Captain Marvel, and starred in his own series. (Rambeau changed her name to Photon out of respect) He is best known for having gone insane (from being given the same omniscience power as his father) and becoming both a hero and a menace until his death.

Genis appared in ''"Captain Marvel''" vol. 3 (1995-1996), vol. 4 (1999-2002), and vol. 5 (2002-2004). For a total of 66 issues, most of them written by Peter David. He then appeared as a member of the {{Thunderbolts}}. He was killed in ''"Thunderbolts''" #100 (May, 2006).

An accidental [[RealityWarper change of history]] had previously resulting in his gaining a "sister", [[ComicBook/{{Quasar}} Phyla-Vell]], who would also take over the Captain Marvel identity for a while. More recently, Mar-Vell has been revealed as the father of [[spoiler:Hulkling of the YoungAvengers]], the result of a dalliance with a Skrull princess.

!!Later versions
During the events of the ''ComicBook/CivilWar'' series, the original Mar-Vell reappeared, apparently having been accidentally transported from the past. He tried to fit in the present, knowing he would have to go back in time and die at some point... until it was revealed during the events of the SecretInvasion that [[spoiler:he was actually a spy for the alien Skrull race -ironically the Kree's biggest enemies- named Khn'nr who had, like many other such sleeper agents, been brainwashed into ''thinking'' that he was the real Marvel.]] Still, he ends up [[spoiler:embracing the Mar-Vell identity and becoming a true hero anyway.]] [[spoiler:Before he dies.]]

The torch was then briefly passed to Noh-Varr, a Kree SuperSoldier from another dimension (originally known as "Marvel Boy"). Although he declared war on Earth at first, he was encouraged by the [[spoiler:Skrull]] Captain Marvel to fight the good fight. He was manipulated to become "Captain Marvel" in the DarkAvengers, but left when he saw the team for what it really was. For a while, he became Protector after contact with this Universe's Kree Supreme Intelligence, before deciding to drop the codenames in the YoungAvengers, where he's simply Noh-Varr.

!! Carol Danvers
In July 2012, a new ''Captain Marvel'' series was launched, with [[MsMarvel Carol Danvers]] taking on Mar-Vell's title, while [[Comicbook/MsMarvel2014 teenager Kamala Khan]] uses the Ms Marvel name.

----
!Tropes:

* AbortedArc[=/=]WhatCouldHaveBeen: before it was decided that the mysterious Captain Marvel who had been glimpsed during Comicbook/CivilWar was the "returned" Mar-Vell (see Back from the Dead below), it was intended to be the recently introduced character Gravity, who had somehow been given the costume and the role of Earth's protector. One can only assume it would have eventually been revealed just who gave Gravity the costume and the job.
* AffirmativeActionLegacy - Monica Rambeau and Phyla-Vell
** TwoferTokenMinority - Monica is female and black, Phyla is female and gay
** The openly-gay Teddy Altman is the new Captain Marvel in the BadFuture seen in ''[[YoungAvengers Children's Crusade]]''.
** And now [[MsMarvel Carol Danvers]] has (FINALLY!) claimed the name for herself.
* BackFromTheDead - Mar-Vell. [[spoiler:But not really.]]
* CaptainSuperhero
* DarkerAndEdgier - About halfway through Genis's run under the name, his title was retooled from a comical series about the relatively earnest Genis to a dark series in which Genis became a RealityWarper with a god complex.
* DisappearedDad - Captain Marvel never met any of his children: [[YoungAvengers Hulkling]] was kept by the Skrulls, and Genis and Phyla were created using his DNA after his death.
* DistaffCounterpart - The [[EnsembleDarkhorse more popular]] [[MsMarvel Ms. Marvel]].
* EndOfSeriesAwareness - During Creator/PeterDavid's run, Rick Jones developed "comics awareness", knowing he's in a comic book and that it was about to be cancelled. The final issue of the series was entirely about the fact that it was the final issue of the series.
* EvilCounterpart - A post-mortem one. In the [[MirrorUniverse Cancerverse]] Mar-Vell made a pact with a pantheon of [[EldritchAbomination Eldritch Abominations]] on his deathbed. Not only did he live, he obliterated death in that universe and turned the Avengers into Lovecraftian horrors under his command.
* FantasticRacism - Most Kree are blue-skinned, but some like Mar-Vell have pink skin (i.e., like that of northern Europeans) and are treated as inferior by the blue-skinned Kree. The extent to which this applies to Mar-Vell (and his status as a hero or a traitor to the Kree) depends on the writer.
* FourthWallObserver - Rick Jones, long-time superhero sidekick, has developed 'comics awareness' as detailed in Captain Marvel #60.
* AGodAmI - Genis-Vell during his crazy period where he restarted the universe.
* TheGoodCaptain
* HyperAwareness: His Cosmic Awareness.
* IHaveManyNames - Common trait among those that take 'Marvel' in their title, outside of the original Mar-Vell himself, is that they will eventually have to change their alias at some point.
** Monica Rambeau's been hit with this so many times it's a running gag. She lost the Captain Marvel moniker to Genis-Vell, and took the name Photon. Then Genis-Vell changed ''his'' name to Photon, having forgotten that Monica was using it; so she changed her name to Pulsar. In at least one storyline she just went by Monica, but has since adopted the name Spectrum.
* KilledOffForReal - One of the comicbook examples that actually ''stays'', unlike [[ComicBook/CaptainAmerica the other Cap]].
* NaiveNewcomer - Noh-Varr both to the Dark Avengers (he didn't even know he was in a team full of villains until Moonstone let it slip) and to the true Avengers.
* NeverLiveItDown - Mar-Vell is best known as "that guy who died from cancer", both in-universe and out. As a career soldier, he ([[spoiler:actually Khn'nr]]) wasn't happy to find out he died on a sickbed instead of in battle.
* {{Nextwave}} - Monica Rambeau was the leader of the group. She used to lead the Avengers as well.
* PietaPlagiarism - The cover of The Death of Captain Marvel graphic novel is very explicitly based on the Michelangelo work.
* PunnyName - "Phyla-Vell" is a taxonomical pun off of "Genis-Vell" ("phylum" and "genus", respectively)
* RasputinianDeath - [[spoiler: Genis-Vell about a year after joining the Thunderbolts as resident {{Gamebreaker}}]]
* RealityWarper - Genis-Vell
* ReedRichardsIsUseless - A variant: Rick Jones comes to Reed and the other superintelligent superheroes of the era and asks them to use their big showoffy brains to cure Mar-Vell's cancer. They come to the uncomfortable realization that they could have been doing that for everyone in the world ''the entire time''.
** And when their efforts fail to bear fruit in time to save Mar-Vell, they '''just stop trying'''! Nevermind that '''other''' people might be helped in the future, nope, it was "save Mar" or nothing.
* SpiderSense: Cosmic Awareness, once appointed Protector of the Universe, Mar-Vell seemed to control it well enough that whenever universal threats or changes occurred that related to him he could but perceive them. When Genis took the power on it drove him crazy because he couldn't fully control it and kept getting [[GoMadFromTheRevelation more information then he needed on possible outcomes]].
* TimeTravelEscape - Mar-Vell [[spoiler:But not really.]]
* TheTopicOfCancer: Possibly ''the'' classic Creator/MarvelComics example: the death of Captain Mar-Vell.
* TwoferTokenMinority: The second Captain Marvel, Monica Rambeau. Done as a pretty earnest attempt to create a strong Twofer superhero.
** Phyla counts as on as well.
* WritingAroundTrademarks - The reason why Marvel Comics makes sure to publish a comic with a character named Captain Marvel in it at least [[http://www.oafe.net/blog/2006/12/captain-marvel-addendum-part-1/ once every few years]].
