A hedgehog? I hate hedgehogs!

— Robotnikhotep I, "Robotnik's Pyramid Scheme"

Robotnikhotep I[1] is a character that appears in the Adventures of Sonic the Hedgehog television series. He is an ancestor of the infamous Dr. Ivo Robotnik from Mobigypt who hates hedgehogs.


Bearing a striking physical similarity to Dr. Ivo Robotnik, Robotnikhotep is an obese, mummified human with a a drooping nose, black eyes with red irises and black pupils, a round body and wiry legs. For attire, he wears linen cloth wraps around most of his body and an yellow necklace.


TV series


In the past, Robotnikhotep gained possession of the Chaos Emerald of Immortality, becoming immortal. However, he would be chased by the Mummified Hedgehog, a being who held a blue emerald necklace that could counter the Chaos Emerald of Immortality's power and sought to protect the world from the wearer of the Emerald. Eventually, Robotnikhotep was mummified and interred in a pyramid, where he slept within a sarcophagus in center of the burial chamber.[1]

Season one

Thousands of years later, Robotnikhotep's descendant, Dr. Robotnik, traveled to Robotnikhotep I's time to get the Chaos Emerald of Immortality. When he was awakened, Robotnikhotep willingly gave the Chaos Emerald to the doctor because he no longer wanted to live forever with the Mummified Hedgehog chasing after him. After giving Robotnik the Emerald, Robotnikhotep disintegrated into dust.[1]

After losing the Chaos Emerald of Immortality, Dr. Robotnik returned to an earlier point in time to get the Emerald again. At that time, Robotnikhotep was still in his coffin in one piece and wearing the Emerald. Dr. Robotnik thus stole the Emerald from him, making Robotnikhotep angry. Sonic and Tails later arrived to find Robotnikhotep enraged, but Sonic did a Triple Spin on him, which made Robotnikhotep's bandages unravel until he turned to dust.[2]


Like his descendant, Robotnikhotep was a violent and malicious person who hated hedgehogs in every form. He also disliked being disrespected, and would attack anyone who insulted him without thinking twice.[1][2]

Phew! Thanks for making me mortal again!
But why should you want to be mortal?
Are you kidding? Who wants to be chased by a crazy hedgehog for a zillion zillion years?

Despite his incredible powers, Robotnikhotep did not seem to like being immortal, mainly because he no longer wanted to have the Mummified Hedgehog chasing after him for the rest of eternity.[1]

Powers and abilities


Robotnikhotep I once had the Chaos Emerald of Immortality, which allowed him to live forever. While wearing it, he could not be wounded, and any damage he received would heal up instantly, even when Sonic's Triple Spin sawed right through his legs.[2]
