The Chimera is a hybrid mutation between three different creatures: an eagle, a salmon and a worm.
April got a psychic connection to the creature after an accident with Donatello's neuro-transmitter.
- The Chimera was, according to Greek mythology, a monstrous fire-breathing hybrid creature, composed of the parts of more than one animal. Usually depicted as a lion, with the head of a goat arising from his back, and a tail that might end with a snake's head. Due to its combination of animal features, the term is often used in modern parlance to refer to any hybrid.
- The Chimera is the first 3-creature hybrid mutant to appear in the series.
- Chimera resembles the giant bird from The Giant Claw, a 1957 science fiction film.
- The nickname Michelangelo suggests for the creature, "Turducken" is a culinary combination of a turkey, duck, and chicken.
Michelangelo: Ooh! Bird, worm and fish. Three animals, one body. I know this one, there's like a perfect name for it in mythology!
Michelangelo: No, Turducken! But Chimera works.
