Eggman Nega

Eggman Nega, initially introduced as Doctor Eggman's alternate reality counterpart from the Sol Dimension ("Sonic Rush"), is in actuality a descendant of Doctor Eggman from approximately 200 years in the future (as revealed in "Sonic Rivals"), now existing in the present time. On numerous occasions he has attempted inter-dimensional destruction, with little to absolutely no regard for his own survival—only to be stopped by Sonic the Hedgehog, whom he has a deep loathing for. In the "Dimension" saga, Eggman Nega begins plotting a very elaborate scheme that leads to the obliteration of reality itself, while keeping his identity and appearance hidden from those he considers a potential threat (at first). Nega proves himself twice as cruel and insane as his ancestor, seeing as he is perfectly aware of what he is doing and what total destruction his plans will cause; his behind-the-scenes influence plays a part in many events that occur throughout the saga, as he himself makes certain that every detail works in his favor, so that his ultimate goal is achieved.
