Souzou Haran was a brilliant scientist that was conducting research on Mars. He created a form of cyborg life with the ability to think for itself. These cyborgs, dubbed the Meganoids, soon ran out of control and killed Dr. Haran along with his whole family, save his youngest son, the 16-year-old Banjou Haran. Banjou escapes from Mars on a rocket with a solar-powered super robot called Daitarn 3, which was built with the special metals of Mars. Now eighteen years old and living on Earth in a luxurious mansion, Banjou fights against the Meganoids with the aid of his faithful butler Garrison and his two gorgeous companions Reika and Beauty. Together they must stop the evil Meganoids which aspire to turn all humans into cyborgs and thus "improve" the human race. (Source: AniDB)

The series follows in the footsteps of manga such as Doraemon and Obake no Q-Taro in that the alien Ganmo (who resembles a chicken wearing sneakers) sets out to help his adopted human friend Hanpeita. The series follows the antics of the duo as they find themselves in the middle of much comedic mischief. One morning Tsukune Tsukuda, out of spite, lets her brother’s pet bird go. But later she has misgivings, and comes home with an egg she has found to give to her brother, Hapeita. Hanpeita isn't all too pleased with the big, odd-looking egg. However, in the meantime it swells up, breaks its shell, and out comes a strange bird-like creature named Ganmo. It speaks like a human being, and comes to live with the Tsukudas. Not wanting to be a mere freeloader, Ganmo takes the initiative to run errands, clean the house, etc…yet he blunders at everything he does. Ganmo the tries to clear his reputation, but his efforts only ends causing more and more confusion. One day a charming girl comes moving in the house next to the Tsukudas.
