Mutagen (2012 TV series)

Mutagen, also known as Mutagenic Ooze, is a mucilaginous substance that has served as a key plot device in nearly every medium of the Teenage Mutant Ninja Turtles. Any creature that is exposed to mutagen will rapidly increase in size, strength and intelligence (sometimes) and even gain superpowers, though its unstable nature makes mutations dangerously unpredictable. It is responsible for mutating, among others, Splinter, the four turtles, and villains such as Dogpound & Fishface.

History
In this series, the Mutagen is depicted as having several similar properties to the version seen in the 1987 series; It blends with the victim's genetics with that of whatever creature they have last made contact with. It has a glowingly blue/green coloration to it.

Rise of the Turtles - Michelangelo refers to it as "mom", due to the role that it played in their creation.

Cockroach Terminator - The Mutagen also has the ability to merge organic substances and inorganic substances, as seen with Spy-Roach, and the same subject shows that it can also cause similar effects to the original comic version, both increasing size and intelligence sometimes.

The Pulverizer Returns! - If a human has not come into contact with another living being before being effected by Mutagen, their bodies will be molecularly broken down, turning them into a pile of acidic goop, with only their internal organs still remaining intact... Pulverizer also states that the Mutagen burns a lot.

Mikey Gets Shellacne - Exposure to a secondary dose of mutagen can accelerate the original mutation; when Bradford (As Dogpound) falls into a vat of mutagen, he is further mutated into a new form known as Rahzar.

The Kraang Conspiracy - It has been stated that the mutagen was not intentionally created as a mutative agent, and apparently had a different effect back in Dimension X, but the new laws of physics in our dimension altered it's function.

The Manhattan Project - The mutagen is revealed to be a natural bio-product of massive, worm-like creatures from Dimension X known as Kraathatrogons.

The Lonely Mutation Of Baxter Stockman - It is revealed that April is immune to mutagen.

Into Dimension X! - In this episode the Kraang perfected the mutagen, revealing it's true purpose; to "terraform" Earth into a new Dimension X. Objects such as rocks or trees sprayed with the perfected mutagen transform into Kraang elements and creatures including humans are mutated into Kraang monsters.

Effects
If ingested the mutagen causes one to mutate into the last thing ingested before the mutagen. For example, Antonio mutated into Pizza Face as pizza was the last thing he ate and a nameless cat mutated into Ice Cream Kitty, as she ingested a mix of mutagen and Ice cream.

Oddly, the mutagen causes scientists to lose their intellect in some cases. For example, Dr. Tyler Rockwell and Dr. Kirby O'Neil who became the instinctive beasts "Monkey Brains" and Kirby Bat. Although other scientists such like Baxter Stockman and Dr. Victor Falco did not develop a "beast mode", they did develop higher levels of antisociality and psychosis.

Mutagen Variations
Monkey Brains - Dr. Victor Falco produced a specific version of the mutagen that would not only mutate Dr. Rockwell but also give him psychic powers, later Falco perfected the serum, giving him the abillity to read minds.

I, Monster - While using rats to test his psychic serum, Falco suffered an accident that gave him new abillities.

Parasitica - Donatello stated that the mutagen effects are usually antropomorphic, which is not the case of the parasitic wasp, that suffered only a size increasement.

Of Rats and Men - Falco is using mutagen in his experiences, using it as base for his rat people formula, which he never got to finish.

The Lonely Mutation of Baxter Stockman - Donnie develops a cure for Kirby and Splinter's mutations, this time called Retro-Mutagen, it takes about ten canisters of mutagen and several months to create one small dose of antidote.

Vengeance is Mine - Baxter Stockman accidentally modifies the mutagen that mutated Karai, making it possible for her to shift back into her human form. As was revealed later in The Pig and The Rhino, this unique mutation can not be reversed by using regular Retro-Mutagen.

Within the Woods - Donatello creates a mutagen based medicine for Leo, "Leo's Elixir" did not mutate him, but once it was out of his body it caused the Creep's mutation. The Creep worships the mutagen and had an altar for Leo's Elixir.

Race with the Demon - Speed Demon spills some Mutagen Gasoline on the road, which later causes the mutation of Dr. Cluckingsworth M.D., who's able to lay Radioactive Mutagen Eggs. Donnie and Casey use the eggs as fueal for the Turtle Racer.

Battle for New York, Part 2 - Michelangelo accidentally created a super retro-mutagen formula that can transform huge amounts of mutagen into retro-mutagen. The Turtles stole a Technodrome and used its mutagen tank to unmutated the whole population of New York, including Kirby.

Tracking Technology
In the beginning of second season Donatello developed devices that would help him and his brothers to look for the missing mutagen canisters.
