Fan Casting Mary McGinnis in Batman Beyond

Terry's mother. After being divorced on friendly terms with his father, where they continued to talk, she would end up living with Terry when she found out about the murder of Warren, who resided with the eldest son. Unaware of her secret, Mary supports her son's current job as Bruce Wayne's 'personal assistant' as a way to get him off the streets. Terry's younger brother, Matt McGinnis, is even mentioned by her in the plot, where she sent him to study in a city outside of Neo-Gotham.
