History Characters / TeenageMutantNinjaTurtlesMutantMayhem

* TheBabyOfTheBunch: According to production designer Yashar Kassai, Donatello is the youngest of the four; a potential series first for the character. This would explain his more youthful voice and frame in comparison to his brothers.

The most fun-loving of the turtles, Michelangelo is optimistic and light-hearted. With a new threat looming, he'll have to flex his creative mind and stand alongside his brothers.

** Leo is Melancholic; he's generally straight-laced and focused on leading his brothers.

** Donatello is Phlegmatic; he's calm and easy-going, with Leo saying that he's the best at talking with people.

The youngest of the turtles, Michelangelo is optimistic and light-hearted. With a new threat looming, he'll have to flex his creative mind and stand alongside his brothers.

* CompositeCharacter: Like their Fred Wolf and ''Out of the Shadows'' incarnations, they're the BigBad's left-and-right-hand henchmen even though they're not the brightest bulbs. [[spoiler:Like their 2012 incarnations, they have the capacity for good and eventually pull a HeelFaceTurn.]] Some promo material also describes Rocksteady as a former Russian arms dealer like 2012's Ivan Steranko (though this isn't reflected in the film itself).
** Them being mutated animal duo instead of humans mutated into hybrid creatures is more in line with [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze Tokka and Rahzar]].

* AdaptationOriginConnection: In the opening scene, Baxter is the one who dumps the vial of ooze down into the sewers to keep it out of TCRI's hands, inadvertently leading to Splinter and the turtles getting mutated. In most iterations, Stockman has no connections to the Turtles origins, and the ooze landing in the sewer is usually the result of a freak accident.

* TruerToTheText: [[DownplayedTrope Downplayed]], but given how much the movie borrows from [[WesternAnimation/TeenageMutantNinjaTurtles1987 the Fred Wolf animated series]], this version of Baxter Stockman doesn't mutate into a fly, and the fly character is a separate character, unlike that show and versions that borrow from that version and like [[ComicBook/TeenageMutantNinjaTurtlesMirage the original Mirage comics]]. That said, he doesn't become a cyborg nor did he create the Mousers and is long dead before the Turtles mutate. He also seems like [[AdaptationalHeroism a nice guy]], unlike the comic book version.

** Previous versions of Splinter had either been human or had been familiar with the kindness humans are capable of, thus he was fairly receptive to the Turtles being familiar with them. Here he has a prejudice against them [[FreudianExcuse due to humans treating him with hatred and disgust when he was a normal rat, and a very bad experience he had when he tried bringing his sons to the surface as a younger mutant]], though it doesn't take much for him to warm up to April. [[spoiler:He does let go of his fear and hatred of humanity by the end of the film though]].

* FantasyForbiddingFather: Splinter generally wants to keep his sons safe from the human world, and scolds them for showing signs of interacting too closely with them. He initially grounds the Turtles for overstaying their supply and sneak-out to watch an outdoor movie event.
* {{Foil}}: To Superfly. Both of them are mutants with an adopted mutant family who grew to hate humans after a bad experience where they tried interacting with humans, only to get attacked by an angry mob, and both act very controlling to their family. However, Superfly is willing to exterminate the human race, while Splinter refuses to stoop to the same level as the humans, [[spoiler:and Splinter ultimately learns to let go of his hatred and make peace with the humans, while Superfly never lets go of his hatred.]]
* FriendlessBackground: Before his mutation, none of his fellow rats liked him. Dogs didn't like him. Raccoons didn't like him. Humanity always hated him the most. The only friend he ''did'' have was a cockroach named Kevin, who got stepped on and had his corpse eaten by Splinter.
* HumansAreBastards: Due to humans treating him with hatred and disgust when he was a normal rat, and a very bad experience where he tried visiting the surface with his sons when they were infants and humans attacked them, he constantly told his sons that humans are "the demon scum of the earth that lust to murder anything different from them". Although that doesn't stop him from admitting that he likes Creator/ChrisPine (and to an extent Creator/ChrisPratt and Creator/ChrisEvans).

* EvenEvilHasLovedOnes: Despite his hatred for humanity, he still loves and misses Stockman, who he considered his father. He also raised the rest of the mutant gang by himself as their adoptive father and is genuinely stung when [[spoiler:they turn on him, but it doesn't stop him from trying to kill them.]]

* {{Foil}}: To Splinter. Both of them are mutants with an adopted mutant family who grew to hate humans after a bad experience where they tried interacting with humans, only to get attacked by an angry mob, and both act very controlling to their family. However, Superfly is willing to exterminate the human race, while Splinter refuses to stoop to the same level as the humans, [[spoiler:and Splinter ultimately learns to let go of his hatred and make peace with the humans thanks to April, while Superfly never lets go of his hatred.]] Superfly even attempts a NotSoDifferentRemark to get Splinter on his side, which fails.

* NotSoDifferentRemark: [[spoiler:When he's on the ropes by his crew and the Turtles, he specifically calls out the bystander Splinter on their common hatred against humans, trying to gain his sympathy. Superfly knows, like Splinter, they have tried and failed to integrate themselves and their families into society, almost getting killed for it. Superfly notes that what makes the two father figures differ is that he's "not a punk about it", which finally causes Splinter to snap]].

[[folder: The Crime Ring Heads]]

* InnocentlyInsensitive: They're teenage boys who spend a lot of time joking around. Their kidding around can get extremely callous and often hurtful -- but they're not ''malicious''. They're just obnoxious teenagers with very limited social experience who think they're being funny.

** Previous versions of Splinter had either been human or had been familiar with the kindness humans are capable of, thus he was fairly receptive to the Turtles being familiar with them. Here he has a prejudice against them [[FreudianExcuse due to humans treating him with hatred and disgust when he was a normal rat, and a very bad experience he had when he tried bringing his sons to the surface as a younger mutant]], though it doesn't take much for him to warm up to April.

* EveryoneHasStandards: As much as he fears and hates humanity, even before he realizes what he's becoming, Splinter still is against Superfly's plan [[spoiler: to eradicate all humanity and replace them as the dominant species; if for no other reason than morality, thinking crossing that line makes them no better than humanity.]]

* HumansAreBastards: Due to humans treating him with hatred and disgust when he was a normal rat, and a very bad experience where he tried visiting the surface with his sons when they were infants and humans attacked them, he constantly told his sons that humans are "the demon scum of the earth that lust to murder anything different from them". Although that doesn't stop him from admitting that he likes Creator/ChrisPine (and by extent Creator/ChrisPratt and Creator/ChrisEvans), who he thinks is the best Chris.

* TruerToTheText: Hamato Yoshi being AdaptedOut aside, this is the first animated Splinter since Nickelodeon's acquisition of the franchise who was a rat mutated into a humanoid, rather than a human who turned into a rat.

* WellIntentionedExtremist: He prevents the Turtles from venturing out of the sewers to congregate among the humans, telling them false rumors about their natures and even grounding them after learning they sneaked in a brief outdoor movie watch. This is all because the one time he ''did'' allow himself and the Turtles out of the sewers, they got attacked and chased away by the public to the point where he has a brief panic attack when he thinks it's going to happen again.

* YouAreACreditToYourRace: [[spoiler:Despite his deep-rooted FantasticRacism against humanity in general, April's aid in alerting him to his sons' peril and aiding him in rescuing them leads to Splinter terming her the only good human he knows, explicitly calling them out for endangering her by helping Superfly's plan along though delivering the final component to him. However, he's still insistent on his family hiding from the human world after their exploitation by TCRI despite that, noting that one good human won't change the danger they face]].

* {{Foil}}: To Splinter. Both of them are mutants with an adopted mutant family who grew to hate humans after a bad experience where they tried interacting with humans, only to get attacked by an angry mob, and both act very controlling to their family. However, Superfly is willing to exterminate the human race, while Splinter refuses to stoop to the same level as the humans, [[spoiler:and Splinter ultimately learns to let go of his hatred and make peace with the humans, while Superfly never lets go of his hatred.]] Superfly even attempts a NotSoDifferentRemark to get Splinter on his side, which fails.

* SirSwearsALot: Surprisingly for an animated movie based on ''TMNT'' (given Raph used to swear [[Film/TeenageMutantNinjaTurtles1990 in the 1990 live action movie]] too), Superfly says "damn" and "hell" quite often in this movie. But then again, he ''is'' voiced by Ice Cube after all.

* VileVillainSaccharineShow: In this relatively cartoony light-hearted and pop culture referencing comedy film about four ninja turtle teenagers, we have this fly mutant who has a relatively high human kill count and who's endgame is to mutate the entire animal population so that they can ''[[KillAllHumans kill the entire human race]]''.

* HumansAreBastards: Due to humans treating him with hatred and disgust when he was a normal rat, and a very bad experience where he tried visiting the surface with his sons when they were infants and humans attacked them, he constantly told his sons that humans are "the demon scum of the earth that lust to murder anything different from them". Although that doesn't stop him from admitting that he likes Creator/ChrisPine, who he thinks is the best Chris.

* FantasticRacism: Superfly absolutely ''despises'' humans, considering all of them judgemental monsters and his goal is to [[KillAllHumans wipe them out.]] The one human he does have a positive impression of is his "father", [[DeceasedParentsAreTheBest Baxter]], and it's implied part of his motivation for trying to enslave humanity is how TCRI's attack on Stockman's lab lead to his apparent death, further convincing him that even a few good human supporters wouldn't be able to protect his crew against the rest of humanity.

* RedIsHeroic: As expected for Raphael with his red mask.

* PurpleIsPowerful: It wouldn't be Donatello if he weren't wearing his iconic purple mask.

* CompositeCharacter: He tends to disrespect Leonardo like various incarnations of Raphael.

* CorruptCorpporateExecutive: She's the executive of a scientific corporation seeking to capture the Turtles and drain them dry of all their blood so she can recreate Stockman's mutagen and create an army of mutant super-soldiers to sell off to the highest bidder. And she doesn't care if she has to kill four teenagers in order to do it.

* TruerToTheText: This is the first animated Splinter since Nickelodeon's acquisition of the franchise who was a rat mutated into a humanoid, rather than a human who turned into a rat.

* TruerToTheText: In the climax, he briefly refers to Donatello as "Donnie", making him the only adaptation of Splinter who uses the Turtles' nicknames, like his [[ComicBook/TeenageMutantNinjaTurtlesMirage Mirage comics counterpart]].

* PluckyComicRelief: Michelangelo brings much of the comedy in the movie. In fact, he wants to join the school's improv comedy team. [[spoiler:Fortunately, he does in the end]]
