A Japanese manga series written and illustrated by Osamu Tezuka in the 1970s, dealing with the medical adventures of the title character, doctor Black Jack. Black Jack consists of hundreds of short, self-contained stories that are typically about 20 pages long. Most of the stories involve Black Jack doing some good deed, for which he rarely gets recognition -- often curing the poor and destitute for free, or teaching the arrogant a lesson in humility. They sometimes end with a good, humane person enduring hardship, often unavoidable death, to save others.
