Aki Kodai

Max's mother and Dr. Taylor's wife. A sketchbook artist and housewife. Not much is known about Max's mother except that she believes (or pretends to believe) that the dinosaurs are dogs, since Dr. Taylor opted to keep his wife in the dark about the truth for the time being. However during the second season, she finds out what the dinosaurs really are. She often embarrasses Max with talks about when he was a baby, and called him by his full name (Maximus) during one of these. Her appearances are generally brief.
