Death Kappa was at first a mummified kappa. It was knocked into the water by drivers (possibly drunk), then was revived in the water. It then befriended 3 children, but the friendship quickly ended when terrorists tried to capture it. They failed, but captured 1 of it's friends, and Kappa came to rescue it's friend. Then it did battle with the terrorists and easily defeated them. Next he had to battle with 3 monsters that had Kappa's DNA. Then their wicked creator unleashed an atomic bomb. 1 of the the 3 monsters survived and mutated into Hangyloas. Hangyolas was destroying the city, and Death Kappa came and easily defeated it. Then Death Kappa began destroying the city furiously, and was calmed down by it's friend when she sung.
