Neptune is just a step under Zeus who is equivalent to Odin. He can just change all of them into mice and step on them.
Neptune wins.
Powers/Abilities: Neptune possesses the conventional attributes of an Olympian god. Like all Olympians he is immortal: he has not aged since reaching adulthood and cannot die by any conventional means. He is immune to all Earthly diseases and is resistant to conventional injury. If wounded, his godly life force would enable him to recover with superhuman speed. It would take an injury of such magnitude that it dispersed a major portion of his bodily molecules to cause him physical death. Even then, it may be possible for a god of equal power to revive him. Neptune possesses superhuman strength and his Olympian metabolism gives him far greater than human endurance at all physical activities. Neptune is one of the strongest of the Olympian gods, and can lift (press) 70 tons. Among the Olympian gods, his level of strength is matched only by those of Pluto and Ares, and exceeded only by those of Zeus and Hercules.Neptune's extraordinary energy-wielding abilities are equaled among the Olympians only by those of Pluto and surpassed only by those of Zeus. Only a few of Neptune's many energy-wielding powers have as yet been depicted. Neptune can fire powerful force bolts from his hands, erect powerful, nearly impenetrable force fields, and create inter-dimensional apertures to enable him to transport himself from one dimension to another. He is a shape-shifter able to change his size, shape and form into that of other persons, animals, and objects. He can render himself invisible to mortals but his invisibility does not work on other Olympian gods, and possibly gods from other pantheons. He is also able to heal the injuries of living beings and transform beings into other shapes and forms (such as when he transformed a white stallion into a sea horse).
As the Olympian god of the sea, Neptune is amphibious, able to survive in water and air. He can also communicate with all forms of sea creatures and move at superhuman speeds while swimming.
