In the world of Teenage Mutant Ninja Turtles continuity, there isn't a substance more significant than the mutagen ooze. This stuff is interdimensional, can heal the sick, and even turn regular animals into humanoid mutants.

The Turtles and the Shredder battle once again, this time for the last canister of the ooze that created the Turtles, with which Shredder wants to unleash an army of new mutants.

Humans who come into contact with the ooze tend to mutate into anthropomorphized animals. The method through which this is accomplished varies. Either an individual melds with the last animal or object with which it came into contact, or they revert to something resembling an animal from which they descended.

T.G.R.I. The T.C.R.I. company, here renamed T.G.R.I., still accidentally create the ooze as a result of accidental chemical waste. However, this iteration of the story doesn't feature the Utrom aliens. This fits in with a very common 90s trend of "toxic waste" playing into larger narratives.

Mutagen, also known as the Ooze, is a viscous substance, which is in virtually every medium and it plays a key role in the origin of the Ninja Turtles.

Mutagen (A.K.A "The Ooze") is a chemical substance that comes from Dimension X, and the reason why the Ninja Turtles (and many of their friends and foes) were created into what they are today, mutants.

Shredder once loved a woman, but it all ended in jealousy and bloodshed. This lost love seems to have made him a bitter and evil man - though maybe he was always rotten to the core. Challenge… dominating the entire crime scene in New York City.

He is an evil Utrom who causes destruction through the universe to make him powerful, making him the most dangerous criminal of the universe. He is the ruthless leader of the Foot Clan. The Utrom Shredder is also the archenemy of the Utroms, the Turtles and their master and father, Splinter.

Teaming up with April and Vern Fenwick, Raphael infiltrated Eric Sacks' laboratory facility, where his brothers were being drained of blood. Before he could free them, Shredder appeared and attacked him, beating the Turtle unconscious and cracking his shell while April freed the other Turtles.

Summary

• Raphael is the physically strongest of the Teenage Mutant Ninja Turtles, capable of incredible feats of strength and overpowering opponents.
• Leonardo may not be the strongest, but his discipline and skill with swords make him a formidable fighter and leader.

Definition. A mutagen is a chemical or physical agent capable of inducing changes in DNA called mutations. Examples of mutagens include tobacco products, radioactive substances, x-rays, ultraviolet radiation and a wide variety of chemicals.

In most versions, the Teenage Mutant Ninja Turtles are created when four baby turtles are exposed to radioactive ooze, transforming them into humanoids. They fight evil in New York City, where they reside in the sewers.
