The Greasy Ocho
Not much is known about the personal history of Dr. Eggman, what information is tangible often lacks important details and is hundreds of years old. What is known about the Gathlain tells a puzzling story.
Born in the wilderness hundreds of years ago, Dr. Eggman was visited and possessed in his youth by a powerfully evil outsider entity. This encounter drives Dr. Eggman towards reconnecting with this entity, some kind of eldridge hedgehog creature.
Recently, Dr. Eggman has been spending his time away from the wilderness, adventuring with AH TOH-DE-MAN and eventually The Greasy Ocho.
