Neptune

Neptune (ネプチューン) is one of the Stardroids from Mega Man V, an aquatic Robot Master with a half-human, half-fish appearance. His weapon is Salt Water, a fluid with substances that can corrode metal. His weakness is the Spark Chaser, but as it's only available in the rematch against him in Wily Star and it should be conserved for the fight against Sunstar, it's recommended to use Photon Missile or Electric Shock.
