Phoenix is an unfinished manga series written and illustrated by Osamu Tezuka. Tezuka considered Phoenix his "life's work"; it consists of 12 parts, each of which tells a separate, self-contained story and takes place in a different era. The plots go back and forth from the remote future to prehistoric times. The story was never completed, having been cut short by Tezuka's death in 1989.

Osamu Tezuka was a Japanese manga artist, cartoonist and animator. Born in Osaka Prefecture, his prolific output, pioneering techniques and innovative redefinitions of genres earned him such titles as "the Father of Manga" , "the Godfather of Manga" and "the God of Manga" . Additionally, he is often considered the Japanese equivalent to Walt Disney, who served as a major inspiration during Tezuka's formative years. Though this phrase praises the quality of his early manga works for children and animations, it also blurs the significant influence of his later, more literary, gekiga works.
