A local fisherman gives Doctor Toru Yano a strange find: a seemingly dead, tadpole-like creature. The odd organism was all the fisherman found while trying to catch shrimp, with the waters oddly absent of the crustaceans. Later, reports come in of a gigantic creature attacking an oil freighter out at sea. Upon seeing the footage, Yano's son, Ken, is convinced it's a larger version of the tadpole-like creature. To discover the truth, the doctor goes scuba diving near where the fisherman made his find. Ken waits for his dad on the shore, only to attract the attention of a smaller version of the monster that sunk the oil freighter. The small boy defends himself with his knife, which leaves no visible damage on the creature although it returns to the water. Ken's father is not so lucky: the beast horrifically scars part of the doctor's face. Seeing that the creature appears to be sludge-like, Ken dubs the monster Hedorah. The media covering his father's attack uses the name, while more reports of sea-related attacks pour in. Experimenting on the sample the fisherman brought him, the doctor makes a startlingly discovery. By applying some polluted water, the creature is rejuvenated. Yano is now convinced it's unlike any creature on earth, as its made of minerals and feeds on a normally hostile environment. Not much later, the creature evolves, sprouting legs as it goes ashore. The creature's rampage is shortened, though, as Godzilla arrives to face it...
