This can get pretty disturbing, but Tezuka never takes it in a sexual direction. Her artificial body makes her look like a small child, and she usually acts like one, but Pinoko considers herself a grown woman and Black Jack’s wife. In most of the stories, Black Jack is accompanied by Pinoko, a cyborg he created from a parasitic twin that had never fully developed. Most of them features valuable lessons about life, usually for the patient or another civilian, but sometimes for doctors or Black Jack himself. The stories are mostly episodic, and the order of presentation is not necessarily the order they occur. On the other hand, he will also often treat a patient for free or a nominal payment if the whim strikes him. For reasons that are not revealed until late in the manga, Black Jack requires large sums of money and will often charge outrageous fees. He drew upon this training and experiences with Japan’s medical establishment for his work on Black Jack starting in the 1970s.īlack Jack (birth name Kuro’o Hazama) is a brilliant physician and surgeon who is unlicensed (reasons differing between continuities) and therefore operates outside the law and the established medical system. Before Osamu Tezuka became a full-time manga creator, he was a medical doctor.
