is a Japanese manga series written and illustrated by Masamune Shirow. The series follows the adventures of ESWAT members Deunan Knute and Briareos Hecatonchires in Olympus. Like much of Shirow's work, Appleseed merges elements of the cyberpunk and mecha genres with politics, philosophy, and sociology. The series spans four volumes, released between 1985 and 1989. It has been adapted into an original video animation, three feature films, a 13-episode TV series, and two video games. In 1986, Appleseed reserved the 17th Seiun Award for Best Manga. Appleseed takes place in the 22nd century, after the non-nuclear Third World War has led to the destruction of a majority of the Earth's people. While countries like Great Britain, USA and China have difficulty maintaining order and power, international organizations like the "Sacred Republic of Munma" and "Poseidon" have been established in the aftermath. The main characters are Deunan Knute and Briareos Hecatonchires, former SWAT members of the LAPD. They are found in the desolated city and invited to join the prestigious ESWAT (Extra Special Weapons And Tactics) organization in the utopian city of Olympus, the new world's most powerful state. Roughly one half of Olympus's population are bionically augmented. The series follows Deunan and Briareos as they protect their new home from both foreign and domestic threats to its security. Originally published in Japan in 1985, Book One Appleseed: The Promethean Challenge was published directly to paperback instead of being serialized, a rarity in the Japanese manga market. This was soon followed by the publication of Book Two, Appleseed: Prometheus Unbound, Book Three Appleseed: The Scales of Prometheus in 1987, and Book Four Appleseed: The Promethean Balance in 1989. The fifth volume was serialized in Seishinsha's Comic Gaia in 1991, but was suspended because, in Masamune Shirow's words, "this form of serialization still did not suit Appleseed". Rumors of a possible Book Five still persist today, though Shirow had mentioned that he has no plans of pursuing it for the meantime.
