Rivals: (a list of only those mortals who earned his direct wrath)

Peirithoos who sought to abduct Persephone, the bride of Haides.

As punishment the god trapped him on a stone chair and eternal torment.

Theseus, who accompanied him on the expedition, was freed at the request of Herakles.

AsklepiOS (son of Apollo) had brought back to life many who had died. Consequently, the myth goes on to say, Haides brought accusation against AsklepiOS, charging him before Zeus of acting to the detriment of his own province, for, he said, the number of the dead was steadily diminishing, now that men were being healed by AsklepiOS. So Zeus, in indignation, slew AsklepiOS with his thunderbolt.
