thats what i never got, since when did dr. robot become always known as eggman, that dreamcast game had me confused
In Sonic Adventure 1, he was known as Robotnik - but everyone just called him Eggman to annoy him. However, when Sonic Adventure 2 was released - he just seemed to always go by the name Eggman (even in menus). As Mouse On Venus said, this was because he was ALWAYS called Eggman in the Japanese Sonic games, and they wanted to avoid confusion by slowly transitioning between the 2 names in the Sonic Adventure series.
