Old Bird

Old Bird is a Chozo from Zebes. He and Grey Voice found Samus on K-2L, and brought her to Zebes. He acted as a foster-father to her, infusing her with Chozo blood, training her, and giving Samus the Power Suit to defend the universe.

Old Bird first appeared in the Super Metroid comic, then in the Japanese version of Metroid Fusion's hard mode endings, the Zero Mission Manga, and most recently in Metroid Zero Mission.
