Momma Robotnik is Robotnik's mother in the cartoon Adventures of Sonic the Hedgehog. She is shown to behave like her son as she also attempts to capture Sonic and Tails. She also for some reason bears a mustache, which is unusual for a woman.
In Momma Robotnik's Birthday she escapes from the "Mobius Home for Really Bizarre Mothers" to visit her son on her birthday. She asks for Robotnik to destroy the national park just outside her Home as it spoils her view. After Sonic foils the attempt to destroy the National forest she vows to capture Sonic. She catches Tails and Sonic has to rescue him. He succeeds and Momma Robotnik is carted away once again to the Mobius Home for Really Bizarre mothers.
