Travelling in the spaceship "Space Colony", Nick, with the help of his ball-shaped robot "Ball Boy", arrive on Earth to study the behaviour and manners of human beings for his doctoral degree thesis. Under the human identity of a young man named Ken Takase, he meets Maki Hayama, a photographer at Shukan Hit newspaper, and later saves her from a building fall. Maki was taking pictures for a scoop about a building which had been mysteriously demolished. Later, she and Ken find that the evil organization "Tentacle" is behind the demolitions and other evil deeds around the world. Nick then decides to extend his stay on Earth and uses his advanced technology and superior powers to protect his Maki and the children of Earth under the alter-ego Machineman, a red and yellow suited superhero. Armed with an advanced technology weapons, he begins fighting Tentacle's cyborgs and protect humankind.

A few episodes later, Machineman succeeds in dismantling Tentacle; however, Professor K flees to Spain and his niece, Lady M, appears. With her aide Tonchinkan, they establish a new organization called "Octopus". Like her uncle, she is allergic to children (whenever she is near one, her nose turns red). In the beginning, she calls up various thieves and legendary criminals from around the world, but later robotic drones are assembled to combat Machineman. By the end of the series, the missing Professor K returns, bringing with him the biggest threat the hero had ever faced: Golden Monsu, a fortified version of Tetsujin Monsu.
