Doctor Ivo "Eggman" Robotnik (Light Mobius) (Pre-SGW)

History
Prior to the timeline being altered by King Sonic, Dr. Eggman still suffered defeat. With his empire crumbling around him, Eggman sought out help from Dimitri, who was immobilized and on life support. When Dimitri refused to help him, the enraged Eggman ripped him from his life support unit, thus resulting in Dimitri needing his head to be removed from his body and preserved in a glass ball. Some time following this, Eggman stole the Master Emerald, causing Knuckles to transform into Chaos Knuckles once again. With his new powers, Chaos Knuckles killed Dr. Eggman.

Following the timeline's alteration, Dr. Eggman's fate is unknown, though the planet was conquered by King Shadow after the Second Robotnik War.

Appearance
Originally Eggman was near identical to Robotnik Prime save the black/blue appearance due to being roboticized. After the loss of his first robotic body, he settled for a more streamlined design. Tall even for an Overlander, Eggman remained obese but became somewhat burlier and less flabby with long, almost disproportionately thin arms and legs. His head is now round as opposed to pointy adorned with both tinted glasses and goggles, and his moustache greatly grew in length, density and mass. Gone are the cape and overlord outfit, in it's place an elegant, red coat sporting two square metal buttons on both sides of the chest in gold with white stripes and yellow cuffs on the sleeves with white gloves covering his hands, and a pair of black pants with matching boots seemingly attached to them bearing circular plates on the both sides of the ankles and three square ones riding up the shin. It was later revealed that behind his pince-nez glasses were the same black eyes with red irises of his original flesh and blood form.

There have a few points where he appears in his 'classic' clothes, which is basically the same costume he wore in the earlier Sonic the Hedgehog games - a red shirt/jacket with yellow triangles (which can be described as either a collar or part of a cape, which can be seen on his back), with black pants with connected boots. He continues to wear his mirrored pince-nez sunglasses. In the the current, post-Super Genesis Wave timeline, he was shown to have dressed like this in his early years. He had also adopted this appearance in the altered reality created by the first ever Genesis Wave.
