Sonic The Hedgehog

Dr. Ivo Robotnik (often known by the nickname Dr. Eggman) is the primary antagonist of the Sonic the Hedgehog series, often appearing as a recurring boss and/or final boss character in many games in the series.

Dr. Eggman is almost always depicted as an obese scientist with an IQ of 300 and a dream of dominating the world. Eggman's constant plots to create his Empire are endlessly thwarted by Sonic the Hedgehog, his arch-enemy, and Sonic's friends. His most powerful creation is none other than Metal Sonic.

In M.U.G.E.N, most of Dr. Eggman's appearances are usually in his classic TV-style version, as seen in various YouTube Poop videos.

FredderyII's Version


Based off the doctor's incarnation in The Adventures of Sonic the Hedgehog, this version contains wonky sprites and many spammable moves with various infinites as a result. With plenty of copies of its own nincombots, it'll be sure to take down that pesky hedgehog quite quickly.


Gruntzilla94's Version

His appearance is the same as FredderyII's version, but this one is a still image and is mostly hated in the M.U.G.E.N community, even though it's a joke character.

Txpot's Version

Robotnik 037 thumb

Txpot's version is based on his video game adaptations. While most of his attacks are unethical, mostly consist of him using hammers, the beans from Dr. Robotnik's Mean Bean Machine, and see-saws to attack, while his special moves consist of himself turning into his creations, such as the Drill Tank. He has brutal A.I. and can summon Metal Sonic, Metal Sonic V2, and Metal Knuckles. He sometimes will start before the round begins by shooting a Proton Cannon. There's also old and new versions, but only the new version is available.

Aperson98's YTP Robotnik


One may notice that this version of Dr. Eggman is similar in appearance to Fatal Fury's Cheng Sinzan, though that's probably because it's a sprite edit of said character. The portly hedgehog hating professor comes armed with attacks based on The Adventures of Sonic the Hedgehog and its associated YouTube Poops, along with the curious ability to summon Ryu and Raiden.


Mugendude26's Version

X Cn6

This version of Eggman only has one attack. He also uses sprites from Dr. Robotnik's Mean Bean Machine.

NeoKamek's Stupid Little Drill Tank

Main article: Stupid Little Drill Tank


This version of Eggman uses sprites taken from his appearance as the boss of Emerald Hill Zone in Sonic the Hedgehog 2. It behaves exactly as it does in Sonic 2, running back and forth across the stage, trying to ram the player with its drill, and firing it as a projectile once its health is low enough.



  • Aperson98's Dr. Eggman's hyper move "Shitty spriteswap super special" is a parody of the overused super/hyper combo moves that alternate between the same sprites.
