This is the Japanese manga supposedly produced/written/illustrated/somethinged by Yoshio Sakamoto in 2003. (Yoshio Sakamoto worked on many Metroid titles as a director, scenario designer, or script writer) The first two untranslated chapters are still available as an e-manga: Chapter 1 and Chapter 2. Translations of chapters 1 and 2 can be found at Mechadrake's site. This manga follows the story of Samus from her childhood up to the final battle of Metroid Zero Mission. Remember, Japanese manga is read from the right to the left!
Thanks to Notelee for the scans. Most of the translations were by RockinX. Other people who assisted in the translation include scholarlyphases, Kragun, and Jennifer Wand. Formatting, text and etc. by Eyes5. I apologize for any errors in the translations because most of us don't have Japanese or English as a first language. If you are a fluent Japanese and English reader, any errors you detect or alternate translations you might offer would be appreciated. A raw version of the manga can be found at The Metroid Database.
