"Fear is the Hunter!"
The Huntsman is entrusted by Zeus to return the wayward Demi-God, Hercules back to Olympus with or without his compliance. The Huntsman co-opts Namor into achieving his ends. Entranced by Sirens, Namor seeks out Hercules and a fierce battle ensues. The spell over Namor is broken just in time for he and Hercules to face the combined threat of mythological monsters summoned by the Huntsman. All this and a Namor/Hercules Fastball-Special too.
