Which creature possesses the ability to turn anything to gold?

The creature associated with the ability to turn anything to gold is King Midas. In Greek mythology, King Midas is best known for his wish that everything he touched would turn to gold. This gift, or curse as it turned out, came from the god Dionysus. It highlights the themes of greed and the unintended consequences of desires, as Midas soon realized that he could not even eat or drink without everything turning to gold.

The other figures mentioned do not share this trait. Medusa, with her snakes for hair, has the ability to turn anyone who looks directly at her into stone, which reflects themes of beauty and punishment rather than the transmutation of materials. The Chimera is a monstrous creature, typically depicted as a combination of a lion, goat, and snake, known for its ferocity rather than any ability to alter physical substances. Satyrs are playful, goat-like beings associated with nature and revelry, and they do not possess the mythical power to transmute objects into gold. Thus, King Midas is specifically linked to the golden touch, making this the correct choice.
