* AdaptationalAngstUpgrade:
** Since the Turtles in this version have been human all their lives, the [[{{Deconstruction}} dissonance between them and regular humans are played up]] when Raphael gets mutated into a turtle, the whole family trying to support him in their won ways and failing miserably.

** Inverted with Miwa, who's raised by her actual parents and has a loving family rather than being trained and raised by the Shredder.

%%* AdaptationalCheerfulnessUpgrade: With Miwa having been raised by her birth parents and the turtles being human in this version, they were all able to live relatively normal lives. Raphael [[AdaptationalNiceGuy has less of a temper]], nothing keeps Donatello from [[RelationshipUpgrade entering a relationship with April]], Michelangelo's CloudCuckoolander quirks are downplayed and all of them have lives outside of being a ninja clan.

* NotSoDifferent: Tang Shen remarks that calming Leatherhead when he's enraged is no different than calming [[HotBlooded Ralph]] when he's angry.

** Oroku Saki's FaceHeelTurn into the Shredder happened after Yoshi gets engaged to Tang Shen instead of after Miwa's birth, meaning this version of Miwa was born in America.

* RealityEnsues: Since Raph, Mikey, and Leo were born humans rather than mutants, they need to completely readjust once they become mutants. Not to mention that turtles have aspects of their biology that the three aren't used to. [[spoiler:Once they revert back to humans thanks to the retro-mutagen, they need to readjust again after having been turtles for so long.]]

''[[https://www.fanfiction.net/s/11309240/1/Same-Difference Same Difference]]'' is a ''WesternAnimation/TeenageMutantNinjaTurtles2012'' fanfic that explores the avenues taken from the many cases of ForWantOfANail mentioned above. The author, [[https://www.fanfiction.net/u/1578614/Sunny-Lighter Sunny Lighter]], has explicitly stated that this is NOT a HighSchoolAU. As the fic shows, a proper description of it would be more of a [[HumanityEnsues human AU]].

** In canon, Zog is shown to be a real jerk when he comes to his senses, think that Raphael controlling him was out of selfishness inherent in Earth and was willing to sacrifice himself to bring the Triceraton Empire there. Here, he gets to know the Hamatos well enough to see their reasoning and even considers them friends for a brief time. [[spoiler:It still doesn't stop him from contacting his superiors, knowing that they would destroy the Earth to keep the Kraang from taking it. The only difference here is that he wants to take the Hamatos with him, seeing their fighting skills and their retro-mutagen worth saving.]]

* AdaptationalNiceGuy: While Casey became a vigilante in the original series to fight street crime that could threaten his family, here he had a more specific goal in-mind; to find his best friend Raphael and the various other classmates that go missing. After he finds out what became of Raphael, Jason (Mondo Gecko) and Timothy (the Pulzerizer/Mutagen Man), he convinces the team to help him look for Martin -- an innocent, bully-bait kid with a prosthetic leg -- out of genuine concern for what happened to him. Not only that, but he completely drops his flirtation with April when he sees that she is in a relationship with Donatello, the two of them having a less {{vitriolic|BestBuds}} friendship than in canon.

* TheMultiverse: After having fallen through the portal, Miwa travels through [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 dimension]], a dimension with four Turtles in superhero outfits flying by futuristic buildings [[note]]Presumably the dimension, where Mikey ended up during 'Reality Check' of the 2003 series[[/note]], ends up on [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze the edge of a crowded dance floor listening to four Turtles singing "Go Ninja, Go Ninja, Go!"]], appears on a New York rooftop where she spots [[Film/TeenageMutantNinjaTurtles2014 four Turtles with 'more muscles than she'd seen than some pro wrestlers']], lands on a fire escape above an alleyway, where she spots a [[ComicBook/TeenageMutantNinjaTurtlesIDW another Turtle version of Raphael, college-aged Casey Jones and a mutant arctic fox]], before making a brief trip to [[ComicBook/TeenageMutantNinjaTurtlesMirage a gritty black and white world]], then finding herself in [[WesternAnimation/TeenageMutantNinjaTurtles2012 a dimension similar to hers]], except for the fact that her brothers are Turtles, and she is Karai, her biggest fear. Then finally, Karai ends up in [[WesternAnimation/TeenageMutantNinjaTurtles2003 a dimension of Turtles]], where she resolves to get some help in returning home.

* HateSink: While H.A.T.E. as an organization in itself can qualify for this, special mention goes to its leader Skonk. [[EstablishingCharacterMoment He is introduced hunting one of his own former subordinates because he tried to leave, having moral objection to his plan to blow up New York City with a nuclear missile. He thinks that all aliens and mutants are an inherent threat to the human race and sees no problem killing humans as collateral damage in wiping them out. When the Hamatos try to reason with him, saying that they know that there is a cure for mutation, [[NotSoWellIntentionedExtrmist he shrugs the idea off, saying that even if they were turned human again, they can no longer be trusted because "once they get oozed, there's no going back."]]

* SitcomArchNemesis: Before he found out that it was run by the Hamato Clan, Bradford acted like this towards the Renaissance Dojo.

* TomboyAngst: Miwa admits to April that one of the reasons why she has trouble accepting her as a friend is because she thinks that her parents wanted a more traditional girly-girl instead of the brawler that she is.

* AdaptationalIntelligence: While Casey wasn't exactly Mikey-level stupid, he was a street-punk who thought more with his hockey-stick than his head, making him a {{Foil}} for the BookSmart Donatello. Here it was done with the singular purpose of investigating a sudden sting of disappearances among his classmates involving himself in it because his friend Raphael was involved in it. When Raph's family dodge his questions, he then orchestrates his study-dates with April probe her for information. When the gang see the notes he kept, they were genuinely impressed.

* AngerBornOfWorry: When Casey joins the Hamatos' nightly excursions, Miwa is the only one against him being there, being the only one among them who is untrained in direct combat and being TheLoad in general. When he hears a recording of her explaining that she is just worried for her safety, he concedes to take classes at the Renaissance Dojo to make sure that he can at least take-care of himself.

* AdaptationalAngstUpgrade: Inverted with Miwa, who's raised by her actual parents and has a loving family rather than being trained and raised by the Shredder.

* AdaptationalJerkass: The Shredder was bad enough as is, but he's ''way'' worse here than he was in the original series with fewer PetTheDog moments. WordOfGod states that the Shredder raising Karai in the prime timeline gave him something to anchor his sanity to. Without her, he went further down the loony bin than he would have ever gone.[[invoked]]
