How The Alien Ninja Turtles Thing Could Work
Most of the origin can remain the same, or so similar that it doesn’t matter. Splinter is a rat formerly owned by a martial arts master (probably from Japan). The rat ends up living in the sewer in NYC, and comes into contact with four baby turtles and a strange ooze. The ooze mutates him into a big talking ninja rat, and also mutates the turtles. They grow up to be teenage martial arts guys who love pizza blah blah blah. We’re square up to this point, right?
Okay, so it’s revealed that TGRI (or whatever) is the company behind the ooze, and further investigation reveals that the corporation is actually a front for an alien invasion from another dimension! Enter Krang, Shredder, etc. The ooze that mutated Splinter and the turtles is revealed to be an alien substance capable of affecting biological changes in Earth animals, which is probably part of Krang’s ultimate plan or something. But through some chain of events, it is revealed that the turtles were NEVER ACTUALLY EXPOSED TO THE OOZE, as they don’t have the genetic markers or whatever to indicate that they were. As a matter of fact, they’re not even from this planet. WHAAAAAT? This would be the big reveal ¾ through the film, where we realize that the turtles are actually refugees from Dimension X, accidentally deposited here as babies via whatever means Krang got here, probably a portal or something. There is a whole RACE of sentient turtles living in Dimension X, and they too are fighting against Krang’s oppression. This gives the turtles’ an ever greater “destiny,” as it seems to be in their genetic code to fight against little psychotic brain creatures.
This lets you have it both ways: the turtles were raised in the sewer, on Earth, thinking they’re mutants. It’s only later that they realize they had it all wrong, and the knowledge of their true origin only gives them a bigger motivation.
I’m not sure any of this makes sense and I may be putting way too much thought into this bullshit but there you go.

It’s simple: 30 days, 30 characters. Here’s my first entry. His name is Krel. He used to be the emperor of a subterranean race of humanoid lizards, but on the surface the only job he can get is at the “Stop N’ Pop” gas station/convenience mart/gun store.
