Tondemo Senshi Muteking) is a science fiction comedy anime series by Tatsunoko Productions,created in 1980. It ran from September 7, 1980, to September 27, 1981, on Fuji TV.[3] Twelve-year-old Rin Yuki loyally supported his father when the world laughed at the scientist for saying that Earth was about to be invaded from outer space. But Rin did not expect to become personally involved—until he met Takoro, the strange young "deputy sheriff" from another world who was on the trail of notorious space criminals. There were only four Kurodako Brothers, but they plotted to use their alien science and natural shape-changing powers to become the secret masters of Earth. With Takoro's help, Rin became the mighty super-hero, Muteking, to foil their schemes.The series was televised in Italy under the title of simply Muteking.

An English dub of episode one was also made, apparently in an unsuccessful attempt to sell the series to the United States. In this one-episode dubbed version (which has been posted on YouTube in three parts), Rin Yuki is named "Scooter Loon," and his father is renamed "Linus Loon." Staff Edit
