It has been suggested that this article, or section be merged into Eggmanland.

The Eggman Empire is a more modern structure of Eggmanland. The Eggman Empire is never built, or seen. Sonic Unleashed was the most recent game to use the name Eggmanland. The early cartoons and Archie comics use the name Robotropolis (though the comics later adopted the name when an alternate version of Robotnik appeared).

In Sonic Adventure 2 the name "Eggman Empire" was used. This can be prosumed as two words in the background while Eggman was broadcasting his threat. Also, in the Dark Story, a scene is called "Eggman Empire".

Sonic X and Shadow the Hedgehog also use the name Eggman Empire. In the Japanese dub of the movie, his home city is called Eggmanland, while in the English dub it is called Robotropolis.

In Shadow the Hedgehog Eggman Empire is one of the factions that Shadow can align himself with along with GUN and Black Arms. When fighting for the Eggman Empire Shadow is guided by Eggman who communicates with him from a Flying TV like apparatus.
