Neo Ultra Q
Gastrobots were snail-like creatures that lived at the ocean floor. In modern times they came to shore to consume geothermal energy for food. One of these animals was spotted by Emiko and her friends while hiking, within days this discovery was the top story of the press. The scientific community eventually caught a gastrobot and studied it, realizing since they had such a high resistance to heat that cold would be their weakness. It was also determined that if their entire population spread uncontrollably they would consume all the geothermal energy in Japan, causing earthquakes. A type of liquid nitrogen gun was developed by the military that was used to coral them into a single valley where they were supposedly frozen to death all at once. However, one gastrobot died on a beach, laying its eggs after passing away from starvation.
