Probably Osamu Tezuka’s most reliable “go-to” Star to play a scientist or a doctor.  He is generally a friendly and competent researcher, concerned with the welfare of mankind.  He will often be the one to make a great discovery pertinent to a crisis, even to the salvation of mankind, and yet be disregarded as a crackpot by the rest of the scientific community.  However, at other times he serves as a voice of sage wisdom – including somewhat famously lecturing Black Jack on the significance of not underestimating the human body and the miracles of nature.

Invited to Nazi Germany during World War II, Dr. Asagumo is asked by Hitler to collaborate with him on the research of the new weapon "Big X". Concerned about the possible effects of the completion of Big X, Dr. Asagumo intentionally delays the progress of the research, conspiring with his co-researcher, the devious Dr. Engel. Immediately before Germany is defeated by the Allies, Dr. Asagumo implants a card inscribed with the secret of Big X in his son, Shigeru, and is then shot to death by the German army. Twenty years later, the card is discovered in the body of Shigeru, who is then living in Tokyo. Soon, an organization claiming alliance with the Nazis appears, steals the card, and completes the Big X project. Dr. Engel's grandson has joined the Nazi Alliance. The completed Big X is then revealed to be a drug that can expand the human body without limitation. Recovering Big X from the enemy, Shigeru's son Akira fearlessly challenges the Nazi Alliance and Hans Engel, who are plotting to conquer the world. 
 
Note: Most of the series is lost media. Only episodes 1, 11, 12 & 40-59 are known to still exist.

In the distant year 2003, Japan is a technological utopia, and robots are everywhere. One such robot, Tobio, was built by the brilliant Dr. Tenma to replace his dead son. But when it soon becomes apparent that Tobio is an imperfect copy of his departed child, Dr. Tenma throws him out. He is rescued from the scrap heap by the benevolent Professor Ochanomizu, a crusader for robot civil rights. Now the little robot, renamed Astro Boy, is given a mission to defend Japan and the world from all manner of sinister threats. Using his seven super-abilities and 100,000 horsepower worth of strength to battle evil, Astro hopes to set an example to the world of the good which all robots are capable of.

This is Tezuka's take on the Taiheiki (太平記/Chronicle of Great Peace), a Japanese historical epic written in the late 14th century that covers the period from 1319 to 1367. It deals primarily with the Nanboku-chō, the period of war between the Northern Court of Ashikaga Takauji in Kyoto, and the Southern Court of Emperor Go-Daigo in Yoshino. (Source: Wiki, edited) Also includes the one shot Gessekai Shinshi (月世界紳士/The Moony Men).

Nuclear testing has resulted in the abrupt evolution of the Fumoon, a tiny but highly intelligent humanoid race on a small island, who are detected by Dr. Yamadano. Except for a few witnesses including the detective Shinsaku Ban, and the young men Rock and Kenichi and Kenichi&rsquo;s sister Pichi (Pinoko), no one believes him. The Fumoon are kidnapping animals from around the world to bring with them as they use their space ships to evacuate the earth, because they know Earth is shortly to be destroyed by an enveloping cloud of black gas created by a stellar explosion. The Fumoon intend to abandon mankind, but one Fumoon, Rokoko, who becomes good friends with Kenichi, tries to help Dr. Yamadano and the others to develop a space ship to allow a few humans to escape, with the help of Dr. Ochanomizu and Dr. Frankenstein.

This work provides information on how to enjoy drawing Manga, while introducing three middle-length Manga stories and 23 four-strip Manga as examples. The very first scene of this Manga is the entrance examination of the Manga College, which is followed by descriptions of tools given by the Principal. The explanation of how to use these tools leads to the first illustrative story.
 
The first story is a story staged in the Civil War period of American history, in which Monster, who appeared in Angel Gunfighter, plays a villain. The second story is anecdotal: it is about a purse that can fulfill three wishes. The purse was given to Chieko, a poor farmer, by the deity of poverty. Next, examples of 4-strip Manga follow, including the "Diary of Ma-chan." The last story is an all-star-cast thriller Manga, featuring Kenichi, Higeoyaji, Rock and others.
