Hercules: The Legendary Journeys
There are no accounts in most Greek myths which state that Hercules met Zoroaster, fought with somebody who seems to be the archangel Michael, helped Thor and all. Dahak is derived from a Persian myth based on the evil god Aži Dahāka, of darkness and sworn enemy to Allah or, in some, Ahura Mazda. The idea of helping Thor comes from the Marvel Comics incarnation.
