Why does Doctor Eggman have two names in the Sonic series? Well, that's what I'll be talking about in today's blog post! Long-time Sonic fans may remember Doctor Eggman as Doctor Ivo Robotnik, so it must have been confusing when he was suddenly called Doctor Eggman later in the games and animations. However, in Japan, his name was always Doctor Eggman. But when the series was localized, Doctor Eggman sounded too silly, so his name was changed. Eventually they decided to start translating his name correctly, but this was confusing a lot of fans. To correct this, they decided to confirm that his real name is Doctor Ivo Robotnik, and Doctor Eggman was a nickname Sonic gave him to mock his appearance. Doctor Eggman adopted the nickname permanently out of spite, and it's stayed that way ever since. This is still a common question in the Sonic fandom, so I wanted to explain it today. Nonetheless, I hope you all still enjoyed this blog post!
