Yonggary or Yongary, also known as Yongary, Monster from the Deep, is a 1967 South Korean Kaiju film directed by prominent genre-film director Kim Ki-duk (no relation to the art film director Kim Ki-duk). In 1999, a reimagining of the film was produced, released in Korea simply as Yonggary and released in the United States as Reptilian.
In the Middle East, a bomb is set off that creates massive earthquakes. Meanwhile in South Korea, a young couple is about to get married and the tension builds when South Korea sends a manned space capsule to investigate the bomb site. The earthquake makes its way to South Korea, caused by a giant monster named Yongary (inspired by a mythical creature in Korean lore). Yongary attacks Seoul and makes his way to the oil refineries where he consumes the oil. A child related to the aforementioned couple turns off the refineries' oil basins; Yonggary, enraged, starts attacking until a chemical explosion at the refinery proves to have an effect on it. The Korean Government then uses oil to draw Yonggary to a local river, and kills it with a refined version of the ammonia compound.
