Oroku Saki, who became Shredder, was once a friend of Hamato Yoshi (Splinter), but out of jealousy and a dastardly set-up, he took over the Foot Clan and vowed to destroy Yoshi. He kidnapped Splinter's daughter, Karai, raising her as his warrior and hiding the truth about her origins. To achieve his goals, Shredder formed an alliance with the alien Kraang, hoping to use their technology, but the alliance was filled with deception and mutual distrust.

Trained in the martial arts by their mutant rat sensei Splinter, four mutant turtles lead a double life in the sewers of New York City. They - Leonardo, Raphael, Michelangelo and Donatello - fight evil, protecting the city from criminals, mutants and alien invaders, all while trying to remain undetected.

A mutagen is a substance that causes genetic mutations, turning living beings into mutants. The Turtles and Splinter were mutated when they were exposed to a mutagen that leaked from the Kraang lab. Splinter saved the young turtles, who then ended up in the sewers. Splinter raised them as his sons and taught them ninjutsu.

Adopted by Shredder, but actually Splinter's daughter. Shredder raised her as his warrior, hiding the truth about her origins. Eventually, she learns the truth and sides with the Turtles. Due to Shredder, she was exposed to a mutagen and turned into a mutant white snake. However, she can change back to human form.

Retromutagen is a substance that reverses the mutation process, returning mutants to their original state. This rare and unstable resource is mined from special sources or created in laboratories, working at the cellular level to correct DNA altered by mutation. Retromutagen is often sought out by the Turtles to help themselves, their friends, innocent victims of mutations, and to prevent villains from creating new mutants, but its use is fraught with difficulties and possible side effects.
