Momma Robotnik, also called Mama Robotnik, is a character that appears in the Adventures of Sonic the Hedgehog television series. She is a human and the mother of the infamous Dr. Robotnik. She is usually kept in the Mobius Home for Really Bizarre Mothers, though she tends to escape from there from time to time. Her viciousness is enough to scare even Robotnik himself, and Sonic considers her his second-greatest enemy.
