Manda is a mighty sea serpent, able to navigate on land with tiny leglike appendages. Originally the god and protector of the undersea kingdom of Mu, Manda became, like so many other monsters, an inmate of Monster Island. In Destroy All Monsters, the alien Kiaaks liberated Manda to participate with Godzilla, Mothra, and Rodan in an all-out assault on Tokyo. Manda was present as a spectator for the final confrontation against Ghidrah at the base of Mount Fuji, in which the golden dragon was defeated. Then Manda returned in peace to Monster Island, where it has lived ever since.
