— Dr. Ivo Robotnik

Doctor Ivo Robotnik Sr. is the main antagonist of Adventures of Sonic the Hedgehog. He is a comically obese scientist. A pompous, bad tempered, and cruel despot, his only goal is to rule Mobius. At least once per episode (usually at the end of the episode after being defeated by Sonic), Robotnik declares his hatred of Sonic with his unmistakable catchphrase "I HATE THAT HEDGEHOG!". Dr. Robotnik also occasionally got help from the one, the only, salesman extraordinaire: Wes Weasely. His only fear is his mother, Mama Robotnik.


Dr. Robotnik looks like an early version of Dr. Eggman, but with a much larger, much more ragged orange mustache, a conical head, a drooping pink nose, black eyes with red irises and black pupils, a round body and wiry legs. He wears a red, black and yellow bodysuit, gray tights and a pair of gray gloves with metal gauntlets. Very rarely, Robotnik also wears a yellow cape to go along with his regular attire.

As a teenager, Robotnik's appearance remained largely the same, with the exception of having facial pimples and a small bowl haircut with dark orange hair.

Robotnik's other outfits include a bathrobe with a fez, a military dictator's uniform with a corset to thin his appearance, a submarine commander's uniform, and various historical uniforms as a result of traveling through time.


According to his own account, Ivo Robotnik's villainy began when he was a child, when he captured his nanny and became dictator of the nursery.[2] Growing up, he was depicted as a fairly typical bully, and was plotting world domination as early as High School. Though he was expelled from High School for unspecified reasons (though it is implied terrorizing his classmates contributed to this), Robotnik did attend higher learning, and graduated as a certified genius alongside fellow evil mastermind John Paul Memo. At some point afterwards, Robotnik lost patience with the eccentricies of his cousin, the derranged Dr. Warpnik, and exiled him to the mysterious Warp of Confusion. Eventually Robotnik built his fortress on top of one of Mobius' biggest mountains, where he would plot many of his schemes to conquer the planet.

Frustrated with Sonic's daily interferences of his plots to conquer Mobius, Dr. Robotnik formed the S.S.S.S.S.S (Super Special Sonic Search and Smash Squad), often called the S.S.S.S.S. Squad, in an attempt to thwart him once and for all. The first member of the S.S.S.S.S.S. was Scratch, and when he attempted to clone Scratch he produced Grounder.

Robotnik is shown through the series to be a tricky, sinister, egotistical, and sadistic man, who enjoys the pain and suffering of the planet. His plans often involve either the destruction of Sonic, or the destruction of an entire city while Sonic is incapacitated. He is the brain behind the majority of the plots in the show, and is exceptionally vain in both his ideas and appearance. Robotnik is openly obsessed with eggs, being the only thing he will usually eat, as well as incorporating egg-themes into many of his inventions. Even his bedroom is egg-themed with his bed being half a broken egg with a yolk colored cover.

Robotnik is often the one to spot Sonic's disguises, although he gets fooled as well. The majority of his traps fail due to either his execution, the machine itself failing, or Scratch and Grounder botching the plan. Despite these and many other, he has allegedly conquered most of the planet (or at least he claims to), and is depicted as being quite rich due to both patents and pilfering the citizens of Mobius.

In the series he has two known relatives, and one built himself. Doctor Warpnik, his crazy cousin, was banished to the Warp of Confusion for being insane. Mama Robotnik, Robotnik's mother, recurs several times, and is the only force Robotnik respects and fears. Robotnik Jr., the son he built himself to carry on his legacy, switched sides to Sonic when he realized his father was crazy. He also makes an alliance at one point with Dr. Qwark, a rival mad genius who also wants to destroy Mobius, however the alliance is short lived as neither can agree on who is to blame when things go wrong. Captain Memo also makes an alliance with Robotnik at one point after a violent misunderstanding due to Sonic, however Robotnik abandons him to the mercy of the Merhogs when the plans go sour.

Love Life

Dr. Robotnik has had a number of romantic interests throughout the series. Though the only woman he has ever truly loved was a red head woman named Lucinda. Unfortunately for the evil doctor, the feeling was not mutual and she married her true love, Lucas. After that, other women have shown interest in Robotnik such as the beautiful Katella, the hideous Snow Height, and the crafty Sonic in disguise, but Robotnik never seemed to be interested in having a relationship with any of them. Robotnik seems to prefer Robotic female companionship because they can be used as a personal slave rather than an equal partner. Robotnik may not have any interest in other women because he still loves Lucinda. On the other hand, his evil heart just may not be capable to love.

As Sonic is not seen in the game, Has Bean, former inhabitant of Beanville, faces all Robotnik's guards including Coconuts, Grounder and Scratch to save the folk of Beanville. When Robotnik sees that his Badniks have got defeated, he decided to take the event on his own hands. As the game is western version of Puyo Puyo, Robotnik has the moveset of Satan from Puyo Puyo. After the duel, Mean Bean-Steaming Machine gets destroyed and Robotnik escapes with his Egg-O-Matic while jolly folk of Beanville have got free.
