In Greek mythology, Hades, the god of the underworld, possessed several powerful items, but it is debatable whether he had the most powerful one.
One of the most notable items that Hades possessed was the Helm of Darkness, also known as the Cap of Invisibility. This helm granted Hades the power of invisibility, allowing him to move undetected and strike his enemies without being seen. The helm was said to have been crafted by the Cyclops and was later given to Hades by the three brothers, Zeus, Poseidon, and Hades, after they overthrew the Titans.
