History Fanfic / SameDifference

* WantsAPrizeForBasicDecency: When Shredder finds out that Raph and Mikey had been mutated, he decides to find a cure for their mutated states with the assumption that it would be enough for Tang Shen to side with him as thanks for curing her sons. The fact that he tries having them imprisoned to keep them from running off certainly does not help his case.

* AdaptationalBadass: Tang Shen is a Kunochi rather than a stay-at-home mother. [[spoiler:She also becomes a mutant instead of Miwa, which puts her on the same level as Slash and Leatherhead]].

* AbusiveParent: Jason's parent's are, to put it mildly, complete assholes. They kick him out after he mutates, and while they embrace him when he returns as a human, they go back to being jackasses when they learn that he was the mutant gecko they kicked out.

* TookALevelInBadass: Tang Shen becomes much stronger [[spoiler:after she gets mutated, with her injuries becoming completely healed and having enough physical strength to easily overpower the Kraang Huntterror.]]

* NeverMyFault: Yes Oroku, Tang Shen's injuries, the fact that she no longer loves you, and her [[spoiler: mutations]] are all most certainly ''your'' fault.

* WickedStepmother: Shredder aspires to be a [[GenderInvertedTrope gender-inverted]] version of this, believing that when he has Tang Shen for himself, he would officially make Miwa his daughter. When he discovers that Leo, Raph, Donnie and Mikey are her sons as well, he extends this curtesy to them.

* AbusiveParent: Jason's parent's are ''kinda'' dicks. They kick him out after he mutates, and while they embrace him when he returns as a human, they go back to being jackasses when they learn that he was the mutant gecko they kicked out.

* AdaptationalBadass: Tang Shen is a Kunochi rather than a stay-at-home mother. [[spoiler:She also becomes a mutant instead of Miwa, which puts her on the same level as Slash and Leatherhead.]]

* 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 own ways and failing miserably.

* MassiveNumberedSiblings: Downplayed, but Yoshi and Shen have five children, Miwa, Leo, Raph, Donnie, and Mikey, the latter four of which are quadruplets.

* AdaptationalHeroism: Miwa is never raised as Karai and is one of the Hamato clan from the beginning.

** Tang Shen survives, so this ensues for her.

* AdaptationalSpeciesChange: Leo, Raph, Donnie, and Mikey are all born humans rather than mutants, while Splinter remains a human instead of getting mutated into a rat.

** Tang Shen survives, so this ensues.

* AmbiguousDisorder:
** [[AvertedTrope Not ambiguous]] since Mikey is confirmed to have ADHD.
** Leatherhead seems to have a massive case of PTSD from all the Kraang experiments done to him.
* AndTheAdventureContinues: [[spoiler:The Shredder's reign of terror has ended once and for all, but his hench-mutants and the Foot Clan are still out there. While the Earth has been saved from certain destruction by the Black Hole Generator, the Triceraton Empire is still out there and fully intends on destroying Earth to make an example out of them as soon as they find a new DoomsdayDevice. Zog becomes disillusioned with the Empire's reign of terror and gets recruited by a resistance movement. While the heroes all celebrate their victory, Professor Honeycutt comes to recruit them to help him stop them, revealing that April's missing uncle Augustus was kidnapped to help build it for them. While reluctant, Splinter and Tang Shen let them go with their blessing, offering to stay behind with the Mighty Mutanimals to protect the Earth while they're gone. [[SequelHook To be continued, someday...]]]]

* SurprisinglyRealisticOutcome: 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.]]

** Since the Turtles are regular humans in this version, they had managed to live fairy normal lives up until they started dealing with the Kraang, including school, friends and (in Donatello's case) a healthy love-life.

* EvilVersusOblivion: [[spoiler:Even though the Hamato Clan don't ask for the Foot Clan's help when the Triceratons invade in this one, they still pitch in to help anyways. While the Shredder could not care less what became of the human race, his various minions most definitely do, Shredder only involving himself when Fishface points out that the obvious fact that if the Earth is destroyed, so is Tang Shen.]]

So many [[ForWantOfANail nails]] thrown into the mix. A world where Tang Shen survived, where Miwa never became Karai, where Yoshi never mutated, and where the turtles are ''humans'' rather than mutants. Either way, knowing Leo, Raph, Donnie, and Mikey, there are still going to be some insane adventures. Hey, their ninjas, you expect them to be normal?

* AdaptationExpansion: Chapters 37 through 42 are set in-between the Season 2 finale and the first episode of Season 3, adapting episodes from the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]] to fit the fanfic's 2012 series plot, as well as a chapter dedicated to how the Mighty Mutanimals recruited Kurtzman and Dr. Rockwell.

* AdaptationalAngstDowngrade: Miwa is raised by her actual parents and has a loving family rather than being trained and raised by the Shredder like in canon.

* 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 his breakout into vigilantism is done with the singular purpose of investigating a sudden sting of disappearances among his classmates. 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.

* NamedByTheAdaptation:
** Mondo Gecko's real name is Jason.
** Sir Malachi's real name is Martin.
