Hercules and the Drama Festival

Hercules and the Drama Festival is an episode of Hercules: The Animated Series. It aired on October 14, 1998.

Summary
Pain and Panic unveil the Cronus Stone – something Cronus coughed up when he spat out the gods, which is deadly to gods and potent to demigods. Hades plans to use the Cronus Stone to put all the gods but him to eternal sleep, with Icarus portraying him at the Drama Festival where all gods will be attending. Fortunately, Hercules finds out that Icarus has been visiting Hades in the Underworld to get into character, and grows even more suspicious at finding Pain and Panic at the festival. He soon realizes that Icarus' mask is made from the Cronus Stone, and forces Icarus to take off the mask as the gods are asleep. Hercules tosses it straight at Hades, who takes out his anger on Pain and Panic.
