History Fanfic / SpiderNinja

* DefeatByTransformation: In Chapter 38, Spider-Ninja, the Turtles, and [[HeelFaceTurn Dr. Octavius]] are hunting down/fighting [[CompositeCharacter Leatherhead (aka the transformed Dr. Curt Connors)]]. Doc Ock wins the fight by pinning Leatherhead to the wall while Spidey pours gene cleanser down his throat. This transforms him back into Doc Connors, winning the fight.

* ObliviousToLove: When April and Casey first meet, [[EveryoneCanSeeIt Splinter, Raph, and Mikey can instantly tell the two humans like each other.]] Petra, however, only sees the two looking at each other strangely and ends up asking Splinter if they're okay. Splinter says that they're fine, and that Petra will understand some day (which just leaves her more confused).

* In Chapter 40, [[spoiler:Captain Stacy invokes this trope, stating that Dr. Mason is unstable and would likely perform experiments on the Turtles if he managed to catch them.]]
* ThatManIsDead: In this story, Splinter [[WasOnceAMan was once the human Hamato Yoshi]]. When Nick Fury asks him which name he prefers, he states that he only goes by Splinter. That said, he doesn't object to Petra using the last name Hamato or having Fury address them as the Hamato family.

* ChekhovsGun: At the end of Chapter 34, [[spoiler:Norman Osborn acquires the severed tail of Leatherhead (which Spider-Ninja accidentally ripped off during a fight).]] In Chapter 40, the [[spoiler:DNA samples taken from the tail are used by the Goblin and Dr. Phineas Mann to mutate Baxter Stockman.]]

** [[spoiler:Doctor Baxter Stockman and Dr. Phineas Mann.]]

** Because they think she's a man, [[spoiler:Bebop and Rocksteady interrogate Agent Coulson for the location of Spider-Man. Coulson [[AlternateContinuity has heard never heard of Spider-Man.]]]]

* NothingIsScarier: [[spoiler:Captain Stacy]] doesn't go into what exactly [[spoiler:Dr. Mann]] did to get arrested and sentenced to life in prison, but he likens it to the scientist playing Dr. Frankenstein, and says that the crime scene was so horrifying that some of the cops needed therapy after. Considering what Ken Ellis said he was charged with, it's probably for the best that we not know ''what'' exactly happened...

* SinisterScythe: Petra was trained in the use of kama, dual-wielded one handed war scythes (which she describes as looking like short scythes). Even after gaining web shooters and spider powers, she still largely relies on her kama when fighting.

* ChekhovsGun: At the end of Chapter 34, [[spoiler:Norman Osborn acquires the severed tail of Leatherhead (which Spider-Ninja accidentally ripped off during a fight.]] In Chapter 40, the [[spoiler:DNA samples taken from the tail are used by the Goblin and Dr. Phineas Mann to mutate Baxter Stockman.]]

* GoingForTheBigScoop: [[IntrepidReporter April]] has a reputation in the journalism community for doing this, to the point that ''Nick Fury'' respects her fearlessness. She shows this trait in Chapter 31, when she accompanies Agent Coulson (against his will) on an investigation.

* InternalReveal: Chapter 16 is this, as Splinter explains the origins of himself and the Turtles to Nick Fury and Black Widow. [[note]] It also doubles as a ShoutOut to the original cartoon, as the origin story they tell Fury is notably similar to the one given in that cartoon's first episode. [[/note]]

* IShallTauntYou: Being a Spider-Person, Petra does this once or twice.

In a distant part of the Spiderverse, four-year-old Petra Parker lost her [[DeathByAdaptation Aunt May]] and [[DoomedByCanon Uncle Ben]] in a traumatizing incident. Luckily, she was found and taken in by Master Splinter, a master ninja (who also happens to be a large mutant rat). She was raised alongside his four sons (all mutant turtles), and became a skilled ninja. After a fateful trip to [=OsCorp=], her DNA was mutated by special spider venom, giving her arachnid-like powers. Together, the ninja siblings spend their nights as unseen vigilantes, defending NYC... and unknowingly attracting the attention of a certain agency.

* BigBrotherInstinct: While they are all capable fighters, the Turtles all have this for their little sister (though she's only a year younger than them) and each other [[InvertedTrope while Petra will do the same for them]].

* SinisterScythe: Petra was trained in the use of kama, dual-wielded one handed war scythes (which she describes as looking like short sickles). Even after gaining web shooters and spider powers, she still largely relies on her kama when fighting.

* TheReasonYouSuckSpeech: [[spoiler:The Green Goblin]] gives one to The Shredder, and rips apart his reasons for going after the Hamato clan while also making it clear he [[EvenEvilHasStandards disapproves]] of Shredder going [[RevengeByProxy after Splinter's kids just to hurt him]]. It ends with [[spoiler:Goblin ''[[FamilyUnfriendlyDeath stabbing Shredder through the chest]]'']].

* WrittenInAbsence: Chapter 22 reveals that Agent Hill wasn't in the first part of the story because of a [[NoodleIncident month-long undercover assignment in Madripoor]].
