* We Animation/HelloKittyAndFriendsSupercuteAdventures: In ''Anime/OnegaiMyMelody'', Kuromi and My Melody are rivals, with Kuromi serving in a villainous role. Here, they're good friends, with Kuromi even offering My Melody sound advice about setting boundaries being healthy for good friendships when My Melody is stressing about a mess caused by Pompompurin.

* ''WesternAnimation/WonderWoman2009'': Continuing from the comic books (see above), Ares here is not only an enemy of the Amazons, he raped Hippolyta at some point in the past. In the original myths, he's her father.

* In ''WebAnimation/DCSuperheroGirls,'' Starfire and her sister Blackfire have only a brief, one-sided rivalry, and once Blackfire makes a HeelFaceTurn in the movie she's introduced in, the two get along fine. One episode even has them bonding together. All other continuities that feature Starfire and Blackfire have the latter remain extremely antagonistic ''at best'' despite Starfire's best efforts, while most have them mutually [[CainAndAbel loathe each other]]; to the point that a major aspect of Starfire's backstory in every appearance outside ''DC Super Hero Girls'' is that Blackfire sold her into slavery.

** The witch Mombi acts as Tip's guardian in the original novel. In this comic, however, she and Tip treat each other as mother and child. Similarly, the Wizard of Oz is almost never even mentioned in the original novel and certainly has no relation to Tip. But in this comic, The Wizard is strongly implied to be Tip's father. With all that being said, since the comic diverges significantly from the original novel, it's not yet known for sure how or even if Tip, Mombi, and The Wizard really are RelatedInTheAdaptation.

** In both the original novel and the comic, Jack Pumpkinhead was originally built by Tip, so he quite innocently declared that he was Tip's son. In the novel, Tip only very grudgingly agrees but spends the rest of the novel resisting the idea. In the comic, Tip quickly and happily embraces the role of Jack's parent.

* Todd and Cooper aren't even friends in the original ''Literature/TheFoxAndTheHound'' book. The Disney film plays them as a tragic friendship.

* ''Radio/XMinusOne'': In [[Recap/XMinusOneE015ColdEquations episode fifteen]], Marilyn Lee Cross stows away aboard the Emergency Dispatch Ship to Woden in order to reunite with her husband Gerry. In the original story, Creator/TomGodwin's "Literature/ColdEquations", Gerry is Marilyn's older brother.

** Skara presumably knew who Raine was in the show proper given that the were the Coven Head of her chosen field, but she never expresses any particular opinion of them and the two are only in the same general area at the very end of the series when everyone comes to Luz's birthday party. Here, Skara is Raine's self-professed biggest fan and lets out an ear-shattering {{Squee}} when she gets the chance to meet them in person.

** While Skara and Viney are hinted to have become friends after they both joined the Flyer Derby team, the two are not shown to have any sort of meaningful relationship in the show. Here, they become romantically involved at some point and are even shown to be married in comics set during the cast's adult years.

* ''WesternAnimation/RudolphTheRedNosedReindeer1964'': In [[Literature/RudolphTheRedNosedReindeer the original 1939 picture book]] and [[WesternAnimation/RudolphTheRedNosedReindeer its 1949 cartoon adaptation]], Rudolph lives in a reindeer village separate from Santa's sleigh team, and doesn't meet Santa until the Christmas Eve when he gets the job of guiding his sleigh: Santa comes to his house to deliver presents, sees his glowing nose, and is inspired. But in the Rankin/Bass stop-motion special, Rudolph is the son of Santa's reindeer Donner and grows up in Christmastown, knowing Santa from birth. Santa is prejudiced against his nose like the [[AllOfTheOtherReindeer other reindeer]] at first, but warms up to him after he and his friends defeat the Abominable Snow Monster, and even more when he realizes that Rudolph's nose can guide the sleigh.

* ''WebOriginal/{{FNAFNG}}'': Thanks to AdaptationalBackstoryChange, the Marionette is an OfficialCouple with Springtrap, as Marianna was previously in a relationship with Spring Bonnie when the two were alive. In canon, there is no such relationship due to Cassette Man's daughter being one of William Afton's victims.

** Most notably between [[LoveTriangle Vivian, Aiden and Gabriel]]. In [[Literature/BloodAndChocolate the book]] Gabriel is in love with Vivian but she doesn't reciprocate [[spoiler:at first]]. Her romance with Aiden starts well but turns sour when he finds out she's a werewolf, culminating in him [[spoiler: trying to kill her]]. In the film, Aiden is clearly the main love interest and ultimately doesn't care about Vivian being a werewolf, while Vivian feels nothing but contempt for Gabriel and he lusts after her rather than loving her.

* ''Literature/GoToSleepAJeffTheKillerRewrite'': Jeff and Liu already know who Randy is since they saw him the day Ben died. In the [[WebOriginal/JeffTheKiller original story]], the brothers didn't know any of the bullies since they just moved into the neighbourhood.
