Johnny Sokko

Shipwrecked, Daisaku (Johnny Sokko) and Juro Minami (an agent for Unicorn) drift to an island and are captured by the BF gang. The island is in fact, a base of the B.F. gang. They happen to discover a huge robot while they are running away.

Emperor Guillotine, king of BF syndicate, plans to take back Giant Robot and to arrest Daisaku (Johhny Sokko), the only one that can give orders to the robot. He sends a huge magic metal globe called Glober to the earth.

Under Emperor Guillotine's orders, Dr. Over, a leading member of BF Syndicate, comes to the earth with a fossil of a devilish space plant called Satan Rose.

Emperor Guillotine sends Dr. Over and Ligon, a new weapon in the shape of a pyramid, to the earth. By operating Ligon, Over destroys oil fields in Araia one after another.

A strange huge plant which has appeared suddenly in Sagami Lake sucks in all the water including a sailing boat and a man in it.

Dr. Over makes Ligon swallow a train near Lake Biwa to kidnap Suzuki, one of the passengers and head of the Kyoto Branch of Unicorn Organization.

A monster called Dorogon swallows a jet plane of the Commonwealth of Sordia when it is flying and an atomic submarine of Furenkov Republic when it is under the sea.

Dr. Tadokora develops QQV, a super-excellent transparent metal. He tests it and QQV endures all the attacks of Giant Robot. BF gang watch the experiments using TV cameras and try to rob the specifications of QQV.

There is the decoding office of the Japanese Branch of Unicorn Organization in the basement of a lighthouse on the coast of the Pacific Ocean.

Daisaku and Minami happen to help a one-eyes man BF members are chasing. According to the man's story, they are trying to kill him as a traitor because he became frightened by the inhumanity of the syndicate and quit it.
