— Momma Robotnik, "Sonic is Running"

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 insanity is enough to scare even Robotnik himself.

Momma Robotnik is a large human with black eyes with red irises, black scleras, and a pink nose like her son. For attire, she wears a bulging pink dress, a large green hat and black shoes. She also takes a green umbrella with her.

She possesses a large mustache like her son. On a few occasions, she did not have it. However, one time, Sonic put her son's mustache onto her.


TV series


Over twenty years ago, Momma Robotnik lived in a house in Chaos City with her son, Dr. Robotnik, when the latter was just an infant. When the family moved, Momma Robotnik left her son's favorite toy, the Fuzzy Wuzzy, in that house. Apparently, this act made Dr. Robotnik the villain he became today.[1] At some point in the past, Momma Robotnik was taken to the Mobius Home for Really Bizarre Mothers due to her low level of care for her son.

Season one

Momma Robotnik threatening her son during her birthday.

On her birthday, Momma Robotnik escaped from the Mobius Home for Really Bizarre Mothers and went to her son's fortress, much for the latter's surprise. She wanted him to destroy the entire Mobius National Park, although the project was halted due to Sonic the Hedgehog's interferences. Later, she decided to kidnap Tails, Sonic's best friend, as use him as bait to catch Sonic. However, due to her own son, the plan did not work. She was then found by the staff of the Mobius Home for Really Bizarre Mothers and taken back to the home.[1]

Tired of being asked by her friends about when her son would defeat Sonic and conquer Mobius, Momma Robotnik escaped from the Mobius Home for Really Bizarre Mothers, took over her son's fortress and his creations (including a transmitter that controlled every machine on Mobius), and managed to adopt Sonic and Tails as her sons. Momma Robotnik then forced Sonic to do a large series of chores while threatening that, if he did not obey her, she would drop Tails into a bottomless pit. Meanwhile, she would use her son's transmitter to take over every machine on the planet. However, due to Dr. Robotnik and Sonic's interference, her intentions were revealed to the law, and she was taken back to the Mobius Home for Really Bizarre Mothers.[2] Some time later, Momma Robotnik would accompany her son on his suppose "retirement".[3]

Some time later, Momma Robotnik was invited by Sonic to Dr. Robotnik's marriage with Katella, and went to the latter's ship, where the ceremony was being held. Angry that Katella did not invite her, she started a violent fight with her. Upset, Katella cancelled the marriage, dumped Dr. Robotnik, Momma Robotnik, Scratch and Grounder out of her ship, and flew away. When the doctor asked her of why she went to the ceremony, she told him that an unknown person told her that her son was being married and would ruin his life. When Robotnik told her the truth that Katella forced him to marry her, Momma Robotnik got angry because he told the truth since she had raised him to "always lie", and started to scold him.[4]

Momma Robotnik with her son during his campaign to become president of Mobius.

Some time later, realizing that one of her friends' son became president of his garden club, Momma Robotnik escaped from the Mobius Home for Really Bizarre Mothers and went to her son's fortress, forcing him to become elected as the president of Mobius. This also made Sonic run a campaign to become president of the planet as well. However, when Sonic managed to become president, the doctor realized that his mother voted for the hedgehog, as she thought that her son could not do anything right. Angry over this, Robotnik called the staff of the Mobius Home for Really Bizarre Mothers and had them take his mother back to the asylum again.[5]


Momma Robotnik is evil, cruel, and terrifying. She is almost always furious and ready to burst into anger at any moment. It is shown that even Dr. Robotnik himself is afraid of her and is unable to oppose her. Momma Robotnik is also ruthless and uses all possible means to achieve her goal of world domination and the destruction of Sonic.

Powers and abilities

Momma Robotnik has proven to be a competent and dangerous enemy to Sonic, Tails and even her own son. Her physical strength is significant; she is able to break through her son's fortress with ease. Also, she once engaged Katella in direct combat, and proved to be the only being aggressive enough to frighten her off the planet.[4]

Momma Robotnik has demonstrated significant cunning and manipulative skill. Despite Scratch and Grounder's programmed loyalty to Robotnik, Momma Robotnik was able to quickly turn them against her son with only seconds of emotional manipulation. She was also able to manipulate the Mobius local government's welfare department to grant her custody of Tails, allowing him to be used against Sonic.[2] During her birthday, she also prepared a trap that came extremely close to killing Sonic and which was only foiled due to sabotage by her son.[1]


While Momma Robotnik does not use any weapons, she uses an umbrella, which she takes with her everywhere. She often uses it to scold her son.


While Momma Robotnik possesses significant strength, she is unable to oppose the staff of the Mobius Home for Really Bizarre Mothers, running from them instead of fighting.[1]


Dr. Robotnik

You no-goodnik! You idiotnik! Can't you do anything?

— Momma Robotnik, "Momma Robotnik's Birthday"

Dr. Robotnik is Momma Robotnik's son. While the doctor respects her when she is near him, she seems to disparage him, often sabotaging his own creations and using them for her own agendas.[3] During Robotnik's childhood, it is also said that she took all of his toys from him to turn him evil, indicating a level of a very low care and affection for her son.[1] Also, during her son's campaign to become the president of Mobius, she would vote for Sonic because she believed that Robotnik could not do anything right.[5]

Sonic the Hedgehog

Ah, how nice to finally meet you, Sonic! I've heard so much about you!

— Momma Robotnik, "Momma Robotnik's Birthday"

Like her son, Momma Robotnik has shown a dislike of Sonic the Hedgehog. She constantly wants to destroy him after he stopped her plans during her birthday, and has often taken over her son's fortress in order to do this.[2] However, Momma Robotnik has also shown some faith in Sonic, as she believes that he can do things better than her son.[5]





"Nice to see you"? Is that all I get after all these years?

— Momma Robotnik, "Zoobotnik"

The truth?! Ugh! What kind of villain are you?! I raised you to always lie!

— Momma Robotnik, "Zoobotnik"

Don't you "Momma" me! I've never been so humiliated in all my life! My friend Cora at the home has a son who was just elected President of his garden club!

— Momma Robotnik, "Sonic is Running"

What did I tell you? You conquer with cleverness and money, not brute force!
