Avalanche!.A giant monster has been spotted in the "Snowfield in the Sky" on Mount Herve. Atom joins the search party for the monster, but Dr. Ochanomizu tells Atom that it is not a monster at all, but a robot that disappeared 12 years ago. Back then, the Chronos Project was being carried out in the Snowfield in the Sky, using the giant plasma wave telescope Merchiades to observe the universe. However, in a mysterious accident that appears to be an avalanche, everything was buried under the snow. The giant monster could be the robot that went missing at that time. The robot had a deep connection with Yūko, the secretary of Ochanomizu. She asks to be allowed to take part in the search. Atom and Yūko join the search party and finally find the missing robot. She speaks to the robot and calls him Gulliver, but Gulliver has lost his memory.
