Neptune, also called Poseidon, is a fictional character in the Marvel Universe.

Neptune is the god of the sea in the Olympian pantheon, and the patron god of Atlantis.

Neptune is the son of Cronus and Rhea, and was born in Olympus. Zeus and Pluto are his brothers, and Hera and Vesta are his sisters. Neptune is responsible for the evolution of Homo mermanus, and is still honored by the Atlanteans, unlike many Olympians who have little or no worshippers on Earth.

Two millennia ago, Neptune destroyed an Atlantean cult of worshippers of Set. He later lived among the Atlanteans for many years as their protector.

Neptune (Marvel) has not been a contender in any CBUB matches.
