* AshcanCopy: ''Flash Comics'', the title that introduced Captain Marvel (then called Captain Thunder). ''Whiz Comics #2'' was the first actual issue; #1 was an ashcan edition and was never publicly released.
* ColbertBump: Mr. Banjo got a bit more recognition after the ''WesternAnimation/RobotChicken DC Comics'' specials featured him.
* DevelopmentGag: The AlternateTimeline of ''Comicbook/{{Flashpoint}}'' has the Shazam powers shared among six kids (Billy, Mary, Freddy, and newcomers named Paco, Eugene, and Darla) who can summon "Captain Thunder" — [[WesternAnimation/CaptainPlanetAndThePlaneteers Sound familiar?]]
* FollowTheLeader:
** Obviously created to cash in on Franchise/{{Superman}}'s popularity, debuting not too long after the Man of Steel. Then he wound up getting so popular, ''Superman'' started to copy ''his'' trends. This included elements such as a female counterpart and the power of flight. And then DC sued Fawcett for making The Captain too similar.
** Ibis the Invincible was one of the many formalwear-dressed magician characters who debuted when Comicstrip/MandrakeTheMagician was at the height of his popularity.
* MissingEpisode: Since everyone kept working right until the end, multiple planned stories were scrapped when Fawcett finally cancelled the Captain Marvel line. Longtime writer Otto Binder recalled in 1974 that, as a therapeutic exercise, he did a SelfParody of the last story he'd written, "a serial [...] featuring the Sivana Family" (most likely "The Triple Trap of Terror" from ''Marvel Family'' #84), where Sivana, Thaddeus Jr. and Georgia kill off their heroes for good and rule the world; the script has never surfaced, likely because his officemates didn't find it that funny at the moment.
* MutuallyFictional: Before the ''ComicBook/CrisisOnInfiniteEarths'' made a MergedReality, ''Shazam'' was a comic book in the ''Franchise/TheDCU'' and ''ComicBook/{{Superman}}'' was a comic on Earth-S. Crossovers would treat the hero visiting the other's universe as a RefugeeFromTVLand and the fourth wall-breaking wink that Superman often does at the end of his strips is shown to be for the benefit of Billy Batson who's reading the comic in his own universe.
* PromotedFanboy:
** E. Nelson Bridwell, who wrote for the 70's ''Shazam!'' relaunch and authored the early comics anthology ''Shazam from the Forties to the Seventies'', was a huge first-generation fan of Captain Marvel (and, for that matter, just about any other Golden Age comic you could name).
** Freelance artist Mayo "Sen" Naito was signed on as one of several lead artists on the ''Shazam!'' (2018) comic; before this, she had a strong following on social media and was know for her superhero fan art, particularly of the Marvel Family (Shazam being her favorite character). Getting the job has been something of a dream-come-true for her.
* RealitySubtext: Whenever Superman and Captain Marvel are in the same comic together, it's a pretty good bet one of them is going to punch the other. This is a reference to their famous court battle, where DC sued Fawcett over similarities to Superman.
* RenamedToAvoidAssociation: During the ComicBook/New52, DC Comics finally renamed their Captain Marvel Shazam (which was the book's ''title'' prior to the rename) after decades of the character [[CaptainMarvel coexisting]] with Creator/MarvelComics's ComicBook/{{Captain Marvel|MarvelComics}}.[[note]]Shazam predated Mar-Vell, but by the time DC snapped up the former Marvel had already trademarked the "Captain Marvel" name.[[/note]] This rename coincided with ComicBook/CarolDanvers' rise to popularity as Marvel's new Captain Marvel.
* ScienceMarchesOn: In the Golden Age comics, Dr. Sivana had a base in the jungles of Venus, and fellow villain Mister Mind was a Venusian native. For a long time, up until the start of the 1960s twenty years later, Venus was speculated to be a hot, tropical world teeming with life, only for the first probe to reveal Venus to be an acid-soaked, scorching hell scape where not even bacteria or advanced machinery can survive past a few seconds.s
** In his first appearance, it is said that The Wizard banished Black Adam to the edge of the entire universe, and that it took 5,000 years of flying at the speed of light for Adam to make his way back to Earth, which would logically place the edge of the universe at 5,000 light years away... except that just the distance between Earth and the center of the Milky Way galaxy is over ''26,000'' light years away, and the amount of light years between us and the observable universe is approximately ''46 billion'', which is the age of the entire universe several times over.
* ScrewedByTheLawyers: Twice over in fact. Originally a creation of Creator/FawcettComics, for a time Captain Marvel was regularly outselling Franchise/{{Superman}}. Not liking this, Creator/DCComics sued Fawcett over copyright infringement, claiming Captain Marvel lifted too many traits from Superman. The courts found in favor of DC Comics, and because of both legal fees and the declining market in the 50s, Fawcett decided to step out of the comic industry. Come the 60s, with the comic industry growing once more, DC was now interested in investing in more comic characters and looked to license Captain Marvel. Irony came into play here because during the same timeframe, Creator/MarvelComics, having started to hit their stride, had already trademarked the Captain Marvel name [[ComicBook/CaptainMarvelMarvelComics for their new character]], so DC could never produce a comic ''titled'' Captain Marvel, opting for [[IAmNotShazam Shazam]] instead. By the time the ComicBook/New52 reboot happened, DC finally threw in the towel and officially [[RenamedToAvoidAssociation renamed the character Shazam]].
** ''Finally'' inverted when they ''could've'' sent [[{{Doujinshi}} Sen a cease-and-desist]] - but instead sent her a [[PromotedFanboy job offer]].
* WhatCouldHaveBeen:
** According to Alex Ross's ''Rough Justice'' art book, he proposed a redesign of the Marvel Family which would've slightly aged Billy to that of a teenager, and modeled him and Captain Marvel after their counterparts from the TV show. Ross's revision would've also included a reworking of Vulcan, the {{Expy}} of Black Lightning from ''Superfriends'', with a backstory connected to Shazam. This direction was pitched when DC's decision to make Freddie Freeman inheritor of Shazam's power had been decided on.
** Going further back, in 1983, a proposal for an updated Captain Marvel was submitted to DC by Roy Thomas, Don Newton, and Jerry Ordway. This version of the character, to be an inhabitant of DC's main Earth-One universe, rather than the Fawcett-based Earth-S universe, would have featured an African-American version of Billy Batson named "Willie Fawcett", who spoke the magic word "Shazam!" to become Captain Thunder, Earth-One's Mightiest Mortal. This alternate version of the character was never used.
** Creator/JackKirby intended to head a relaunch of the Captain Marvel books as part of his defection to DC Comics. Supposedly his intention was to at the very least edit or write the books while also giving Captain Marvel's co-creator C.C. Beck work again. Legal issues prevented Kirby from convincing the higher-ups at DC to go through with it but it's implied that it was this proposal that convinced DC to eventually finally do something with the property and introduce the Marvel Family into the DC Universe. Kirby's relaunch would not have been any attempts to modernize or alter the character and his status quo but simply make the books {{Uncancelled}}.
** The major talents in Fawcett said that if they could have kept the Captain Marvel characters into the 1960s, they likely would have responded to Creator/MarvelComics' rise with its character-based narrative style by adapting the idea of Captain Marvel unambiguously having young Billy's personality themselves.
* WordOfGod: The Wizard was intentionally drawn to look like an older Captain Marvel by C.C. Beck, foreshadowing the LegacyCharacter aspect of the Shazam power.
