Leonardo = Hannibal (the serious, no-nonsense leader).
Raphael = Baracus (the hot-headed muscle of the group).
Donatello = Murdock (the brains of the operation).
Michaelangelo = Face (the ladies' man). Also, Murdock and Michelangelo are both Cloud Cuckoolanders.
April O'Neil = (the chick).
Well, there's one single link to it all: Ninja Turtles: The Next Mutation. As much as Peter Laird hates it, the reveal of the TMNT multiverse effectively allows it to still exist somewhere in that cosmos.
With that in mind, remember the Next Mutation crossover episode of Power Rangers in Space? Now that we've linked TMNT to PR, note that Mighty Morphin' Power Rangers had a three-part Poorly-Disguised Pilot for... Masked Rider. That show, while being a hackjob, is nevertheless a Kamen Rider series, and so part of the multiverse etablished by Kamen Rider Decade.
(And if you bring up the argument that Masked Rider became a Show Within a Show in Power Rangers Time Force, there's still another backdoor: the Rangers' connection to Super Sentai, which leads to the canonical Samurai Sentai Shinkenger crossover in Decade...)
- Alternatively, the Turtles in Power Rangers in Space are that universe's version of the Turtles, not being connected in any way, they're just Mutant Turtles.
- But they still wouldn't have existed without the existence of Turtle-Prime in the first place, so...
- Perhaps it's the multiversal equivalent of a Venn diagram
, where two multiverses overlap and create a middle universe (i.e. the way The DCU and Marvel multiverses work in regard to their Amalgam Universe). Although thinking about it too much makes my head hurt a bit.
- The multiverses each have something that works that way. DC has Hypertime and Marvel has Cross-Time.
- Perhaps it's the multiversal equivalent of a Venn diagram
- But they still wouldn't have existed without the existence of Turtle-Prime in the first place, so...
- The orphan Australian girl found the Chipettes after they were recently exposed to the mutagen.
- The mutagen might have come from the Australian branch of TCRI.
- Though they got their relationship back on track by the time in TMNT, where it's becoming more serious between them.
The giveaway are the colors they wear.
- Michelangelo being Orange, is Gluttony. His main shtick is his constant consumption of pizza, which extends even to other parts of the Multiverse as well. In the 80's cartoon, this is done to the extent of putting insane toppings that most would find repulsive on them (such as jellybeans and guacamole).
- Raphael is Red, and is obviously Anger. Raph is constantly referred to as the most anti-social Turtle of the group, and one that has to constantly find outlets to channel his rage.
- Donatello is Purple, and therefore Pride. Don takes pride in his vast knowledge of machines. Consider 'Turtles Forever', where his 80's counterpart explained something that worked in his universe (using a wrench as a hammer, building a mini-portal device) only to have his 2003 counterpart constantly dismiss it until he actually sees it for himself.
- Leonardo is Blue and is Sloth. This one is a bit dodgy to explain, but here goes. Did you ever notice that there are times when Leonardo would just leave the team to their own devices? That he feels that he's not worthy to lead the Turtles, and goes off on his own? That's his fear of constant commitment to ideals talking. Everybody looks up to him, and he's the most diligent Turtle, but it makes one wonder if he goes on these Sabbaticals just to get away from the responsibility of that burden.
- April is Yellow, and is Greed. But this only applies to the 80's show. April would do anything for a hot scoop, even to the point of holding her boss at ransom in an early season episode just to get a news crew. She'll even put herself in harm's way just to get an exclusive, and gets notably miffed if Vernon gets the drop on her stories. Though, to be honest, Vernon is more representative of this than her, but she has her moments.
- Irma is Light Blue and Lust. She constantly awaits the day when some handsome guy would sweep her off of her feet, and even ventured into a sewer when she thought one was there (who was actually Splinter, much to her dismay.) Irma has the makings of someone who'd tackle anything that moves, and then some.
- Shredder is Jealousy (but sadly, does not wear Green at all.) His origin story reeks of this, killing Hamato Yoshi and his lover for the latter spurning him.
- Unlikely, since NiMH is based on Maryland, US, while Splinter came from Japan. Though there might be a NiMH branch near where Yoshi lived. It's also possible Splinter was taken by NiMH sometime after Yoshi and Shen was murdered. It would have to be in New York since Maryland is miles apart.
- In the movie rats were shown being gathered from an urban setting before being taken to NIMH. Perhaps it was New York, an easy place to find rats.
As we know, in the cartoon, Baxter Stockman and the Shredder continued to find more fragments of the Eye of Zarnov (or Eye of Sarnath as it was called in the comic), eventually managing to reassemble it. Eventually, Baxter would be mutated into a fly by Krang and Shredder would continue to menace the Turtles with the assistance of Bebop, Rocksteady, and Krang until he was replaced by Lord Dregg in the final two seasons.
In the Archie Comics series, however, Armaggon went back in time and intervened, causing Baxter and Shredder to not get any fragments of the Eye of Sarnath other than the one that shrinks objects. This also caused Baxter to never continue working for the Shredder, and as a result, he never became a fly-man. This also caused the other changes of the origins of the enemies and allies of the Turtles that managed to appear in both the comic and the cartoon, plus Krang, Bebop, and Rocksteady being banished to other planets to leave Shredder as the central antagonist. Armaggon's interference with the past altered the timeline and kept the continuity of the Archie Comics series from being a complete copy of the Fred Wolf cartoon's continuity.
- Obviously. April has one hot bod.
It is shown in the 1st film that the Turtles and Splinter were created by the Ooze coating their bodies and slowly but progressively giving them their mutant forms. The same could be said for Tokka and Rahzar even though it is not seen directly, otherwise the Scientist that was forced to create them would've mentioned it. Also since he didn't bother to feed it to them (he just sticks a hose in there and lets the Mutagen do its work), it's all the more reason to believe they didn't consume the Mutagen either. However when the Turtles first see Super Shredder, they immediately assume that Shredder drank a vial of it (he was last seen threatening to coat a woman with said vial) as a desperation attempt to kill the turtles since maybe coating his body in mutagen would've took too long to go into effect.
The reason for Super Shredder's rampage rather that immediately going after the Turtles could imply that Super Shredder was at a Dementia-level of both insanity and pain at the same time. While his body may be indestructible from the wood falling on him, the Mutagen he consumed was completely destroying his innards until it most likely killed him.
- Or, as the fourth movie implies, he's not really dead.
Not only did he defeat and humiliate Tatsu in front of his students in the first film, he's also the one who threw the switch and supposedly murdered Shredder, which Tatsu is clearly overcome with vengeance at early in the second film. With neither Skill in Ninjitsu nor job tying him down, its pretty clear why supplementary material says he's "out of town" at the time.
- The Red Sky seasons would like a word.
