* FanPreferredCouple: Shadow and Renoir are this to the semi-canon Renoir/Davianna. Shadow and Renoir argue like a married couple at times and many of their interactions tend to come off as UST. Add the fact that they've had some rather tender moments, are far more developed as characters than Davianna, and seem to be [[ShipperOnDeck shipped by Carole]] it's understandable why this is.
* MoralEventHorizon: What Donatello does with [[spoiler:his clone, "Leo", and especially Officer Tony Howard after the latter stumbles upon his lab and experiments.]]
* NauseaFuel: Frequently. Characters vomit on panel, mangled corpses abound and there's plenty of blood from the second panel on.
%% * NightmareFuel: It starts [[http://www.mntgaiden.com/en/?id=601 here]]. Except for those who are following the comic, since it's not such a surprise. For them, the true horror started [[http://www.mntgaiden.com/en/?id=602 on the next page]].
%% ** [[http://www.mntgaiden.com/en/?id=622 And some pages later...]] it got even worse...
%% *** And just when you think the fuel is gonna stop flowing, [[http://www.mntgaiden.com/en/?id=642 he had to throw in this particuar page... Dear Lord...]]
%% ** And now, this... [[http://www.mntgaiden.com/en/?id=659 freak]] makes the [[NightmareFuel nightmare fuel]] go into [[SerialEscalation ever increasing]] levels... Not safe to your mind or soul.
%% ** Even before pages of chapter 22 started being released, [[http://www.mntgaiden.com/en/?id=751 the cover]].
* RescuedFromTheScrappyHeap: Renoir was initially disliked for being exactly like every perverted anime protagonist and their father - Often being called the worst part of the comic in the beginning. However, as he received character development, showed some hidden depths, and improved his mentor/student relationship with Raphael, fans of the franchise warmed up to him and he became praised among the fanbase for being an interesting deconstruction of what it would be like to be thrown into the Turtle's world without warning.
* TheyWastedAPerfectlyGoodCharacter: The major consensous on Davianna so far. Mostly due to not getting much character development outside her relationship with Renoir. Luckily this hasn't caused her to be a scrappy.
* WhatDoYouMeanItsNotForKids: ''Franchise/TeenageMutantNinjaTurtles is best known from child-friendly cartoons and comics, but this fancomic is based more on [[ComicBook/TeenageMutantNinjaTurtlesMirage the original comics]], that were a lot more violent and satirical. Tellingly, the cartoon it draws most from is the slightly darker 2003 one. [[RRatedOpening The prologue should be warning enough to the reader]].
%% ** Perhaps this is best exemplified by [[http://www.mntgaiden.com/en/?id=680 this page]].
* TheWoobie: EVERYONE at one point or another.
