A revered God of the undersea kingdom of Mu, Manda has proven himself to be a fighter. Combined with the hate, cruelty, and malice of a warlord, Manda attacked the submarine Gotengo without hesitation. Relentless and filled with animal lust, he coiled his scaly mass around the reinforced hull. Constricting like some demonic python, he tried to seal the humans' fates. However, the Gotengo was not defenseless and charged the hull with an electrical charge. The god was struck with pain, and retreated to the depths, where it was followed and frozen by the Gotengo's Freeze Cannon.

After the conflict, the animal was dragged to Monsterland, where it proceeded to live the rest of its life in peace, until the Island was controlled by the Kilaks near the dawn of the century. Manda was first sent to destroy London. Afterwards it proceeded to Tokyo, where it, along with Godzilla, Mothra and Rodan, leveled the city. It was not long before the human race was able to overthrow the Kilaak's power over the monsters, and, after a climactic battle with the space demon King Ghidorah, Manda was returned back to his Monsterland where the monster lives out on his rocky cliff side home.
