Poseidon

Marvel's god of the seas made a splash in the Modern Age when Greg Pak, Fred Van Lente, and Clayton Henry introduced this Poseidon in Incredible Hercules #123 in 2009 — dropping him straight into the thick of Olympian drama alongside Zeus, Hercules, Hera, Athena, and Ares. It's a fittingly august crowd for a deity of his stature. What's intriguing is the breadth of his catalog footprint: from those mythic Incredible Hercules pages all the way to the contemporary world of Miles Morales: Spider-Man, suggesting this ancient power has a way of resurfacing across Marvel's ever-expanding universe. Rare appearances can mean an outsized impression — and for a god who commands the depths, that tracks perfectly.
