A world-renowned scientist who is widely recognized as one of the greatest scientific minds of all time, Prof. Robotnik was responsible for several groundbreaking creations, including his crowning achievement, Shadow the Hedgehog, making him a “Modern Da Vinci”.
More than fifty years ago, Robotnik was asked by the president of the United Federation to lead Project Shadow, a medical program to invent immortality, which he accepted in hopes of finding a cure for a deadly disease affecting Maria.
Ultimately, Prof. Robotnik managed to create Shadow the Hedgehog, though not without drastic measures; the military detained him when his project was deemed too dangerous. Learning that Maria had been killed by the military, Gerald fell into madness and spent his final days plotting revenge against humanity.
8. Scourge the Hedgehog
Debut: Sonic the Hedgehog Issue 11 (1994)
Scourge the Hedgehog is a character that appears in the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics. He is the version of Sonic the Hedgehog belonging to Anti-Mobius (also known as Moebius). Scourge is almost identical to Sonic in almost every way, except in terms of personality, completely the opposite of him (i.e., he’s everything bad and mischievous that Sonic isn’t). Scourge mistreats others, is selfish and greedy, has a great desire for power, and is the ruler of Moebius.
In his early years, Scourge was little more than a rival to Sonic, with occasional fights between the two hedgehogs, plus he was physically identical to Sonic. However, Scourge attempted to steal Master Emerald along with Rouge the Bat. He used the emerald’s Chaos energy to intentionally become stronger than Sonic, but after Locke hit the hedgehog while absorbing the emerald’s energy, Scourge transformed into a green-colored individual who was finally able to distinguish himself from Sonic.
7. Mephiles the Dark
Debut: Sonic the Hedgehog (2006)
Mephiles the Dark is the main antagonist in Sonic the Hedgehog (2006). He is the malevolent conscience, mind, and will of the sun god Solaris.

After his birth, Mephiles was sealed within the Scepter of Darkness by Shadow the Hedgehog but was freed ten years later during a skirmish between Shadow, Rouge, and Dr. Eggman. After freeing him, Mephiles orchestrated a centuries-old plan to free Iblis from Princess Elise and reunite with him, which happened when he killed Sonic the Hedgehog.

During an assault, Infinite was hired by Dr. Eggman to protect his facility, only for him and his squad to fall into the hands of Shadow the Hedgehog.
Ashamed of defeating him, Infinite decided to obtain the power of the Phantom Ruby as a means of not only becoming stronger but also abandoning his “weak” past self. With his newfound power, Infinite helped Eggman expand the Eggman Empire to its largest size to date after defeating Sonic the Hedgehog.

4. Metal Sonic
Debut: Sonic the Hedgehog CD (1993)
Metal Sonic is an evil Badnik version of Sonic the Hedgehog and arguably Dr. Eggman’s deadliest creation, built for the sole purpose of destroying Sonic. Deployed during Eggman’s operations on the Little Planet, Metal Sonic engaged Sonic in battle and lost, though he would return repeatedly to challenge Sonic and his allies.
Extremely accurately modeled after Sonic, Metal Sonic not only resembles the organic version of him but can also mimic his movements and achieve speeds that match and even exceed Sonic’s. While primarily serving as Eggman’s dutiful and silent enforcer, Metal Sonic is an intelligent machine with a very dark side.
A ruthless, aggressive, and ruthless killer, he is obsessed with proving his superiority to Sonic and eliminating him for good to the point where he has rebelled against Eggman more than once to achieve his goal. However, he always fails in the end. To this day, Metal Sonic continues to be one of Sonic’s most formidable foes.
3. Shadow the Hedgehog
Debut: Sonic Adventure 2 (2001)
Shadow the Hedgehog is a hybrid being created based on a black anthropomorphic male hedgehog/Black Arms. Shadow resembles Sonic in many ways, even in speed thanks to his jet skis, reaching speeds equal to Sonic’s. He is Sonic’s arch-rival and the very antithesis of him in every aspect of his life.
Shadow was created as the “Ultimate Life Form” by Gerald Robotnik, using Black Doom’s DNA, and is the end result of Project Shadow. His purpose was to provide ways to develop a cure for deadly incurable diseases, more specifically for Gerald’s granddaughter, Maria Robotnik, but he was captured and put into stasis by the military when he has deemed a threat to humanity.
Fifty years later, Shadow was freed by Dr. Eggman to enlist him in his plan to take over the world. Shadow initially worked with him, but secretly sought to destroy the planet to avenge Maria, who had been killed by the military, but was persuaded to save him from Gerald’s doomsday plans.
In the process, Shadow lost his memories of him and as such tried to discover the truth of his past, during which he met Black Doom and the Black Arms; in the end, Shadow regained his memories, discovered the truth, foiled Black Doom’s agenda, and saved the world. From there, he continued his mission to protect humanity for the sake of Maria.
2. Knuckles the Echidna
Debut: Sonic the Hedgehog 3 (1994)
Knuckles the Echidna is a 16-year-old anthropomorphic red echidna who is both physically powerful and highly resilient. He is also the guardian of Master Emerald, a powerful ancient jewel that he solemnly owes to protect from anyone who seeks to abuse his power. He is also the only surviving descendant of the echidna race of Clan Knuckles.
His dominant traits are his super strength and the two spike-like knuckles on each of his gloves, from which his name is derived, which he can use to dig and scale walls. He can also catch the wind under his dreadlocks to glide through the air. Knuckles’ name is derived from the four knuckles, two on each hand, which are actually sharp spikes.
A loner by nature, Knuckles is independent, headstrong, and serious, but gullible and short-tempered to the last. He is completely dedicated to his duty, spending most of his time on Angel Island protecting Master Emerald, rarely worrying about anything unimportant. However, when his friends and other people need his help, Knuckles can always trust that he will be willing to step down and prove that he is a loyal and good-hearted hero.
He is also one of Sonic’s oldest friends and rivals. Although he is usually depicted as the guardian of Master Emerald, he was originally described as the guardian of the seven Chaos Emeralds of Angel Island.
1. Doctor Eggman
Debut: Sonic the Hedgehog (1991)
Doctor Eggman (formerly called Doctor “Ivo” Robotnik) is a major antagonist and nemesis of the title protagonist, Sonic the Hedgehog. He is one of the most famous antagonists in video game history and one of the most popular villains in video game history, alongside Bowser from the Super Mario Bros. franchise, and Ganondorf from The Legend of Zelda.
Grandson of Professor Gerald Robotnik, Doctor Eggman is a mad scientist with an IQ of 300 and a very childish demeanor. He tries to take over the world by enslaving the population through robotization to serve his whims. Sonic and his friends are thus always in charge of stopping him. He is obese, with an egg-shaped body (hence his name, Eggman literally meaning egg man).
He is sometimes drawn with long arms and spindly feet and sometimes with shorter limbs, it depends. He tends to exclusively use red and black color combinations and is often portrayed with tinted contact lenses. In other descriptions, his eyes are black with red pupils, but his glasses make him look like a scientist.
