History WesternAnimation / TMNT

* BigNo: Raph gets one when [[spoiler: he returns too late to stop the Stone Generals from taking Leo]].

* ScrewTheRulesImDoingWhatsRight: Splinter forbids the Turtles from fighting in the surface until they can act as a team. He becomes frustrated with Leo and Raph's constant argument. But when Leo gets captured, he decided they've been hiding for too long and it's time to take action.

* CainAndAbel: Leonardo and Raphael, with Leo being worshiped as a hero in South America and Raphael being labeled as a hero by some and antagonistic vigilante by others during his job as the Nightwatcher. [[spoiler: Then there's their already strained brotherly bond eventually turning into full blown sibling rivalry culminating into a fight which ends in one of the two brothers almost getting killed by the other.]]

* HeroWithBadPublicity: Raph as the Nightwatcher, many viewing him as an antagonistic vigilante. Raph gets annoyed and calls a restaurant owner out on it after saving him from one of the 13 Monsters, only to be regarded with fear.

* MoodWhiplash: The funny scene with Raphael and a tiny monster is followed by [[spoiler:a scene where Raphael and Leonardo have a falling out and fight, all culminating in Leonardo getting captured by the villains]].

** In the end, [[spoiler:Max Winters who is [[ReallySevenHundredYearsOld Really over 3000 years old]] gets ReducedToDust and Mikey accidentally inhales some of it resulting in a funny moment, similar to the end of the 2003 series episode ''[[Recap/TeenageMutantNinjaTurtles2003S3E14TheDarknessWithin The Darkness Within]]'', where C.F. Volpehart, who is really thousands of years old, gets ReducedToDust and Mike accidentally steps over the dust and gets grossed out over it]]. Suprisingly, the PG rated theatrical movie executes the similar scene in a much more LighterAndSofter manner than the SaturdayMorningCartoon made by Creator/FourKidsEntertainment.

* ScreamDiscretionShot: Leo screaming when he [[spoiler: gets taken captive by the Stone Generals and the Foot Soldiers]].

* TantrumThrowing: After Leo gets captured by the enemy and Raphael fails to save him (given [[ItsAllMyFault he was the one who weakened Leo in the first place]]), he ends up knocking down spears and weights as he tries to tell Splinter about what happened.

* VigilanteInjustice: Leonardo doesn't like the vigilante, Nightwatcher, because he thinks he does more harm than good in stopping the criminals and protecting the city at night. Things get more complicated when Leonardo discovers that the vigilante he hates [[spoiler: is his brother Raphael in disguise]] and they have a fight on the rooftop.

* WhatTheHellHero: Splinter chides Donnie early in the film for losing his temper and bickering with Raph, since as acting team leader, he shouldn't get provoked by Raph's poor attitude. Later, Splinter chews out the Turtles and Leo in particular when they go out to fight against his wishes. When Leo blames Raph, Splinter snaps at him that as the leader, the buck stops with him for not keeping the group under control.

** Leo thinking the Nightwatcher as a vigilante is going too far is similar to Raph's initial reaction to Casey Jones in the original comics, the 1990 movie and the 2003 series.

* FamilyOfChoice: In the beginning of the movie, Winters aka Yaotl, trusted his own brothers more than others. Once they betray him and the Turtles and Splinter along with April and Casey help him cure his curse of Immortality, he refers to the Turtles and Splinter as "brothers".

* AmbiguouslyRelated: The [[AllThereInTheManual bio text]] of Karai's action figure described her as The Shredder'a daughter, but no clear indication of this is made in the film, and the reliability and canonicity of said bio text is debatable. [[note]]It might have been confused with her [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 counterpart]] who did [[RelatedInTheAdaptation have that backstory]].[[/note]]

** The little-known prequel comics (issue #1) are this in terms of the Nightwatcher character. [[http://freyreh.tumblr.com/post/38990259750/tmnt-movie-prequel-1-raphael You'd never know that Raphael got the suit from an old vigilante that]] [[MyGreatestFailure he failed to save]]. By extension you also wouldn't know that as the new Nightwatcher, Raphael is a LegacyCharacter. It's like a side of depression fries to that milkshake of family strife the movie exhibits, isn't it?

* ActionGirl: April O'Neil for the first time in film. She is shown to be trained in ninjitsu and later holds her own against the Foot as easily as the others.

* TantrumThrowing: After Raphael fails to rescue Leo, he ends up knocking down spears and weights as he tries to tell Splinter about what happened.

* YouFightLikeACow: Leo continuously taunts the Nightwatcher, over his inferior [[AlwaysSoemoneBetter (compared to Leo)]] combat skills and his anger problems.

* AnAesop: The film's main themes are about how family needs to communicate with each other and understand that their actions can have serious consequences for others, especially if they lash out in anger.

* TheGlovesComeOff: After Leo learns that Raph is the Nightwatcher, the two brothers get into a gigantic argument that eventually devolves into a duel. Raph, having already lost the vision-restricting helmet, draws his sais, the weapons he's been trained with since birth, and Leo, realizing that Raph is serious, draws his swords, indicating the two brothers are ready to fight for real.
