Mom is a character from Dexter's Laboratory.
Dexter appears to be fairly close to his mother, and appears to have inherited his intellect from her. He is sometimes embarrassed by her, such as when she kept causing a loud ruckus at a chess tournament in an effort to cheer him on and ended up getting him disqualified for making noise in a quiet zone, but mostly their relationship is a common affectionate one.
