[[caption-width-right:350:"Shellshock" takes on a whole new meaning.]]

->[[TheReasonYouSuckSpeech Always blaming other people when you screw up... You're quite irresponsible, Raphael... And yet, you keep competing with me to become the leader... That's just laughable! You're just a failure! An undisciplined and brainless piece of trash that fails in everything it does! Your very existence is a dishonour to our Sensei!'']]
--> -- Leonardo to Raphael, Prologue.

What happens when you mix the ''Teenage Mutant Ninja Turtles'' with DarkerAndEdgier? You get this gem of a fancomic.

Created in 2004 by an aspiring artist known in DeviantART as Tigerfog, ''Mutant Ninja Turtles: Gaiden'' is an AlternateUniverse doujinshi that takes place seventeen years after a pivotal event that happens in the comic's Prologue. The entire comic is hosted on [[http://www.obscurezodiac.com/ Tigerfog's website]].

The story begins when the Teenage Mutant Ninja Turtles were [[DepartmentofRedundancyDepartment teenagers]]. [[BadassGrandpa Master Splinter]] recieves a package from an unknown sender, but leaves it hidden as he teaches Leonardo an old technique. As this happens, the ever-curious Michelangelo recruits Raphael so they could find out what Splinter received. They both find an [[ArtifactOfDoom old, broken katana]] and, from then on, certain characters begin to act [[AxCrazy unusually out-of-character]]. The conclusion of the Prologue leaves the four brothers [[HeroicBSOD psychologically traumatized]].

Cut to seventeen years later, when the Ninja Turtles are adults. A [[SixthRanger mysterious fifth turtle]] shows up on the news, causing the older Raphael and Donatello to resurface once more in an attempt to recruit it. However, the fifth turtle, whom Raphael names Renoir, knows nothing about how he became a turtle. All he remembers are his memories as a human named Augustus Amherst. Despite this, Raphael takes Renoir under his wing, making Renoir his student and establishing the set-up of the main story.

This comic is a must see for any TMNT fan and is very well-recommended for people who enjoy a good plot and interesting character development.

'''This comic uses the following tropes:'''

* ADayInTheLimelight
* {{Animesque}}: MNT Gaiden is drawn in a shounen manga art style.
* AnyoneCanDie
* ArtifactOfDoom: A VERY nasty one.
** To be more specific, it is an EvilWeapon.
* ArtEvolution: There's a considerable jump in the artists skill between the prologue and Chapter 1.
* BarehandedBladeBlock: Donatello in the prologue.
* ButThouMust: Leonardo being forced to allow Karai and her Foot ninjas to [[spoiler: assassinate the Morinagas to prevent the Yamata-no-Orochi from being reborn.]]
* CerebusSyndrome: The whole point of the prologue. And chapter 17 could very well be a new one...
* CharacterDevelopment
* ChivalrousPervert: Renoir. He steals Shadow's panties, but according to Davianna, he would not kiss her before she turned 18 even if she *asked* him to.
* ComedicSociopathy: The Bakabakashii comic is made of this.
* CornerOfWoe: In the Bakabakashii (4KOMA) comic, [[spoiler: Mona Lisa and 80s Mikey]] go through this.
* CuriosityKilledTheCast: This is the driving force behind the plot; the cast didn't die they were just left mentally scarred.
* DarkerAndEdgier: Tigerfog's MNT Gaiden universe is loosely based off the original TMNT comic book universe.
* DemonicPossession: [[spoiler: Yamato-no-Orochi to the Totsuka left behind by Susano'o, which became the source of the Curse.]]
* DirtyBusiness: [[spoiler: The Foot Clan have been killing the Morinaga bloodline to prevent the return of Yamata no Orochi because an ancestor failed to completely exorcise the demon from himself, thus every member of his bloodline contains part of the curse. Even the Foot consider this a NecessaryEvil with many of the killers of entire families being DrivenToSuicide over their actions. Worst part? ''Leonardo is helping them do it'']].
* DysfunctionalFamily: The MNT after the events in the prologue...could ya really blame 'em.
* EyeScream: Raphael, Renoir, and now [[spoiler: Tony]].
* EvenEvilHasStandards: Subverted. [[spoiler:The Foot Commander stopped one of his underlings from raping Davianna because it was beneath them... because the Foot Ninja should focus on the needs of the Clan over their own desires, not because of any inherent morality.]]
** Played straight with [[spoiler: the Foot Ninjas involved with killing the Morinaga descendants being driven to despair over murdering innocent families, often to the point of ending their own lives.]]
* FatalFlaw: The MNT and possibly Renoir.
* {{Flashback}}: The prologue takes place seventeen years before the main plot.
* {{ForeShadowing}}
* GratuitousJapanese: Sound effects and action effects are represented by Japanese symbols, rather than English onomatopoeia. [[http://www.mntgaiden.com/en/?id=608 For example.]]
* HarmfultoMinors: Kids are not exposed to violence here... they're SUBJECTED to it.
** Shadow almost drowned twice. First when she was a kid, then [[spoiler:as a plan of the Foot Clan to lure and kill Michelangelo. And before that, she got a [[NoHoldsBarredBeatdown VERY ugly beating]] from a ninja she kicked in the groin]].
** Her best friend Davianna was also kidnapped. [[spoiler:She had to watch Shadow being punished, and then she was almost raped.]]
** Being the newest turtle, Renoir is in the line of fire. And that meant [[spoiler:[[EyeScream losing his eye]] and falling from a building, after a scrape with a ninja]]. [[GoodThingYouCanHeal Good thing he could heal]]...
*** Maybe Augustus was transformed into Renoir, maybe not. Either case, there is no way [[http://www.mntgaiden.com/en/?id=85 this]] could have been pleasant to him...
** Carole Amherst was taken hostage by [[spoiler:[[WhattheHellHero Donatello, of all turtles]]]], when he was being chased by police, and ended up in hospital.
** Chapter 18 introduced (HUGE SPOILERS) [[spoiler:a young, cloned turtle made by Donatello as a test to clone Splinter. His main uses for him? Guinea pig and punching bag.]]
* HonoraryUncle: The MNT are all uncles to Shadow.
* InformationWantsToBeFree: A reporter is upset after receiving word that she needs to report the mysterious deaths done by Foot ninjas as emigrations abroad. She is pissed out and leaves in protest while the cameras are rolling, saying that the deaths are done because of a conspiracy.
* MysteriousPast: Davianna; possibly Renoir. If Renoir is Augusts Amherst then his past would be less mysterious.
* NiceJobBreakingItHero: Mike comforting and reassuring Donatello, unaware that [[spoiler: Donatello wants said reassurance because he's doubtful about his crazy-ass plans.]]
* NotHimself
* OfficialCouple: April and Casey.
* OffWithHisHead: Decapitation is very frequent in this series.
* PlayingWithSyringes: [[spoiler:Donatello.]]
* PoorCommunicationKills: The prologue revolves around this.
* PureIsNotGood: Oroku Saki, the Shredder, was one of the only people immune to [[spoiler:Orochi's]] curse because he was already pure evil.
* TheReveal
* SanitySlippage: [[spoiler:Donatello.]]
* ScienceIsBad
* SingleIssuePsychology
* SlidingScaleOfIdealismVersusCynicism: Holy crap. If your only experience with the Turtles is that goofy cartoon series you watched when you were six, with defanged baddies and wise-crackin' youngsters, you are ''not'' gonna be prepared for the level of violence and gore this piece dishes out. As for the statement this makes about the world, check out [[http://www.mntgaiden.com/en/?id=642 this page]] directly contrasting the idealism of a child with the psychotic actions we've just witnessed from one of the "heroes".
-->People like that are called heroes, right? And heroes, they don't do bad things, right?
* TakeThat: In [[http://www.mntgaiden.com/wordpress/comic/bakabakashii-63/ this Kakabakashii]].
* TimeSkip: To a time where the turtles are in their mid-30s.
* ThisIsYourBrainOnEvil: And how!
* TrueCompanions
* VomitDiscretionShot: Subverted. A lot.
* WhamEpisode: Orignally Chapter 17, but was split into three chapters (17, 18, 19) due to its size. Now Chapter 18 is the aforementioned WhamEpisode.
* WhatTheHellHero: [[spoiler: Renoir tells off Nobody for allowing him to enter his home and possibly endanger his sister on the grounds that if Renoir did attack his family, Nobody would know for certain that he was still a feral mutant and put him down.]]
* WiseBeyondTheirYears: Renoir, Shadow, and Davianna have all displayed wisdom that average teenagers in a place like New York City in this day and age may not have.
