Mama is the matriarch of the central family group. Though outwardly human compared to her explicitly monstrous family, she possesses subtle supernatural traits, including the pointy ears shared by some of her children. Her typical demeanor remains calm, gentle, and somewhat absent-minded, focused on domestic responsibilities as a housewife.

However, prolonged stress, particularly from household management or encountering spherical objects, triggers a drastic shift. Under these conditions, she reveals her witch heritage, adopting a volatile and destructive disposition. This alternate persona exhibits significant magical capability, including flight using a broomstick.

She is married to Papa, a Frankenstein monster-like figure, and acts as mother to their children: Gabriel (a vampire), Sara (who can turn invisible), Noelle (an angel-in-training), and Lucca (an elf-like inventor). Mama cares for her family despite their chaotic dynamics. Her own mother, Baba, is also a witch who disapproves of humans, creating occasional familial tension.
