Old Bird

Old Bird is a Chozo from Zebes. He had found Samus on K-2L after the attack, and brought her to Zebes (Though Grey Voice was not pleased at this)). 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. When she returns to a ruined Zebes as a Federation Police, Samus hears his final communication before fleeing with (most) of the rest of the Chozo.

A similiar character appears in the non-canon Super Metroid comic, living on an unnamed planet and looking much older. Armstrong Houston and Samus arrive from Zebes after her Power Suit is damaged and he agrees to use a risky technique to try to fix it. During this time, he explains the story of Samus and the Chozo to Armstrong.

Old Bird first appeared in the Japanese version of Metroid Fusion's hard mode endings, Metroid (manga), and most recently in Metroid Zero Mission.
