History
Kaoru Kamikiku submitted this concept to Toho at the same time he was working on concept art for Godzilla vs. Barubaroi. Like Kazuki Omori's Godzilla vs. Ghost Godzilla treatment, he called for the return of the Oxygen Destroyer, which would ultimately serve as the origin for Destoroyah. His drawings of "Deep-Sea Life" showed a spiny dragon with a long neck.
