History
Marvalus threw Great Mazinger into the ocean intermediately after he destroyed Gravalus. Then when Boss Borot joins him underwater, Tetsuya tells Boss that he should make a device that emits electromagnetic waves so that it could slow Marvalus. When the device works, Great Mazinger cuts Marvalus' wing and falls into the ocean, presumably destroying him.
