She comes from the Child's Realm, recently escaped. She had been a baby sitter, a mother figure, a toy and more for the Child. Toshiba has a mixture of child-like exuberance, an action hero, a maternal role, and a fearful animal in a new home.
Her mask is of a mid-50's African-American woman. She is tough and stern for the most part. Her mien is that of a living action-figure. One part Barbie, one part G.I. Joe, her skin looks like hardened plastic, with articulated joints. Her neck down looks likes some sort of transformation anime hero or 'Power Rangers' style uniform, beneath her clothes.
