No, Dr. Eggman is the ancestor of Eggman Nega, as revealed in the Sonic Rivals series. Dr. Eggman Nega despises him due to his constant failures when facing Sonic the Hedgehog, scarring his family name.
Silvers timeline is plagued by Dr.Eggmans decendent, Eggman Nega, who likely talks at great lengths about how much of a failure his ansestor was.

Eggman's full name is Dr. Ivo Robotnik.In the comics it is Dr. Julian Ivo Robotnik.
In the 1990's Dr Robotnik's (Eggman) best robotic invention was Metal Sonic, believed to be the key to destroying the world (as mentioned in SONIC HEROES). Later on he builds an extremely powerful robot in in the E Series called E-123 Omega which is a very powerful boss in Sonic Heroes.
The character of Robotnik/Eggman was created by SEGA in 1990. When the character was shipped over to the U.S along with the first Sonic game in 1991, SEGA of America decided to officially make his name Dr. Ivo Robotnik, because it sounds better. He stayed Dr. Eggman in Japan. By 1998, SEGA had decided to revert his name to Dr. Ivo "Eggman" Robotnik worldwide, for unknown reasons.
Dr Eggman Nega appears in Sonic Rush Adventure and Sonic Rush 3, he is more crazy and insane and looks slightly different than Dr. Eggman.
Since he's Dr. Eggman's grandfather, I would think he's about 81.
He voices as Dr. Eggman, Dr. Gerald Robotnik (Sonic Adventure 2 and Shadow the Hedgehog), and Eggman Nega.
Nega Eggman was an alternate reality version of Dr Eggman in the Sonic Rush series. The "Nega" version looked exactly like the original character but had different colored hair, skin and clothes. This idea was borrowed in Scott Pilgrim.

doctor eggman/doctor robotnik is fifty-seven. But in the show sonic X doctor robotnik is doctor eggmans grandfather so that shouldve tipped you off that he's old.
Dr. Eggman's voice is usually performed by actor Mike Pollock in the English-language versions of the Sonic the Hedgehog video games and animated series.
dr. Eggmans name is Ivo dr. Robotniks name is julian dr. robotnik was in the older sonic games, comic books, and movies. i did see an article that said eggman was robotniks robot he made before he died. But some say dr.robotnik is eggman, but how would that explain the different names, could eggman be snivley? or did robotnik change his name? did he die and leave eggman his robot in charge? that is your choice.
