History ComicBook / Batman66

* AdaptationNameChange: Harley's civilian name went from Harleen Quinzel to Holly Quinn.

* EvilTwin: Egbert is Alfred's cousin but otherwise fits by being a CriminalDoppleganger.

* TheButlerDidIt: Subverted. There's a story titled "The Butler Did It!" but [[spoiler:the butler's cousin is the true villain.]]

* EvilTwin: Eggbert is Alfred's cousin but otherwise fits.

* CanonCharacterAllAlong: Surprisingly, the final issue manages to retroactively identify ''the generic criminals shown in the original show's opening sequence'' as characters who originated from the comics. The first three crooks punched by Batman and Robin at the start of the intro are revealed to be the Terrible Trio, the man with a sheet over his head is identified as the Shiner, the green villain is King Cobra, the red-haired mad scientist with a beard is Professor Achilles Milo (with one panel showing that he's wearing a wig and a fake beard, exposing his traditional black-haired look), the bald, bespectacled man is the Atom-Master, the mustached man in a brown suit holding a gun is revealed to be this continuity's version of Deadshot and the man in a blue shirt and cap is identified as this continuity's Signalman. What's most impressive is that all of these villains existed before the TV show did.

* ActorAllusion: In Issue five Catwoman hums to herself a refrain of "I Want To Be Evil", a nod to Creator/EarthaKitt as this was first time the series depicted Catwoman in the likeness of Eartha Kitt who played her in season 3 of the series.

* HowWeGotHere: Issue #24 starts with Batman and Robin buried in the sand and surrounded by scorpions. The scene changes to two days before.

* RaceLift: Poison Ivy's nationality was unspecified in the comics but here she's a SouthernBelle.

* CompositeCharacter: The comic reveals False Face's true identity as... [[spoiler:Basil Karlo, aka Clayface, from the comics, and gives him an in-universe power boost that makes him a complete shapeshifter.]] (Although he's much more obscure in that medium, False Face had appeared in the comics, and wasn't an original TV series character).

Following the cancellation of the main series, it was brought back for a number of mini-series and one-shots featuring crossovers with other works of the era. Alongside its first run came a counterpart in ''ComicBook/WonderWoman77'', a similar digital-first title featuring new stories set in the continuity of the 1970s ''Series/{{Wonder Woman|1975}}'' TV series, now shown to take place a decade after Batman's adventures.

** After the end of the main series in 2016, there have been crossover mini-series with ''Series/WonderWoman77'', ''[[Series/TheAvengers1960s Steed and Mrs. Peel]]'', ''Radio/TheGreenHornet'', ''Series/TheManFromUNCLE'', ''ComicBook/LegionOfSuperHeroes'', and ComicBook/ArchieComics.

In 2021, DC announced a SpiritualSuccessor, ''ComicBook/Batman89'', further exploring the world of ''Film/Batman1989'' and ''Film/BatmanReturns''. Shortly afterwards, ''ComicBook/Superman79'' began, a comic set in the continuity of ''Film/SupermanTheMovie'' and its direct sequels.

* MythologyGag: The Bane story also features significant references to the wrestling-related [[Manga/{{Batman}} Batman manga]] story "The Hangman of Terror".

!! Tropes:

* CompositeCharacter: The comic reveals False Face's true identity as... [[spoiler: Basil Karlo, aka Clayface, from the comics, and gives him an in-universe power boost that makes him a complete shapeshifter.]] (Although he's much more obscure in that medium, False Face had appeared in the comics, and wasn't an original TV series character).

* {{Irony}}: Bookworm [[ShootTheTelevision breaks a TV]] by [[ThrowTheBookAtThem throwing a book at it in rage.]] The book in question? A self-help book about anger management.

* LeaningOnTheFourthWall: The AsLongAsItSoundsForeign incantations from an ancient spell book used by Bookworm are phonetically pronounced to sound like the lead actors of the original TV show ("Yeevon Kregg," "Ah-Dam Wezt" "Buhhrt Warhrrd") the {{Written Sound Effect}}s commonly used on that show ("Baham-Pouw-Krazh") and the famous theme song ("Nanah Nanah Nanah Nanah B'aht M'nnn")

* MirandaRights: [[ParodiedTrope Parodied]]. In Issue #39, the Archer steals police equipment and gives it to criminals. After handcuffing a cop, one of those criminals tells another one to read the cop's ''wrongs''.

** Issue #31 has Joker put on a comedy routine in Arkham Asylum. While [[OrphanedPunchline we only see the punchline,]] one of the jokes he tells is clearly [[ComicBook/TheKillingJoke The Killing Joke.]]
** While dealing with the Siren in issue #2, Batman gets an assist from his date Kathy who looks like a pre-crisis ComicBook/{{Batwoman}} due an illusion cast by Siren.

-->'''Bookworm:''' Rotting your minds on ''television'' while a ''treasure trove'' of books sits unread?! No ''wonder'' your brains never put anything ''out!'' You ''simpletons'' never put anything ''in!''

* PyrrhicVictory: [[spoiler:Holly successfully wipes the Joker's brand of madness out of everyone by absorbing it herself, later becoming "The Harlequin"]].
