A chimera is a mythological creature from Greek mythology, typically depicted as a monstrous hybrid made up of parts from different animals, most famously described as having the body of a lion, a goat's head rising from its back, and a serpent for a tail. This creature symbolizes the blending of different elements into a single entity, often representing chaos or the unnatural. Chimeras are significant in stories where they serve as formidable adversaries to heroes, reflecting the struggle against hybrid monsters in human experience.
