Dai Youchuu Sasora

During winter vacation, Hideo accompanied his brother Yusuke on a whaling ship to the Southern Ocean. There, they were attacked by a scorpion monster. Hideo launched an electric harpoon to drive off the monster and allowed their ship to escape. A few days later, Dr. Carl Schmidt came from Germany and revealed the true identity of the monster on TV. The monster, named Sasora by the scientists, was a red scorpion modified for military use by Dr. Von Schmidt's brother during World War II. However, just as he was about to carry out his plan, the FBI destroyed his laboratory in the Amazon, and the red scorpion disappeared into the jungle. Dr. Carl speculated that the red scorpion was exposed to radiation from a nuclear test in the Amazon and became a giant. He apologized on behalf of his late brother, but then came the news that Sasora was on its way to Tokyo!
