Mother (マザー, Mazā) is an android used to disguise Eden's main computer. She is mute and is protected by the mother keepers.
Mother's hair is long in length, lying just beyond her chest and is silver in colour. She has purple eyes and is always seen carrying a small teddy which is white in colour and has bead eyes and a stitched mouth. She is always seen wearing a dress which is black in colour with puffed shoulders and goes down roughly to her knees.
Mother is quiet as she is a CPU, she comes across as child like because she doesn't speak and is nearly always seen carrying her teddy .
Mother is the central CPU of Eden and also doubles as the key to the "Golden age" weapons that are in the world.
Jim is the person who Maintenance's Mother through out the series.
