Mobotropolis (disambiguation)

In the SatAM, Archie comics (which followed on from SatAM) and Sonic Underground continuities of the Sonic the Hedgehog universe, Mobotropolis is the capital city of the planet Mobius.

Robotropolis
When Dr. Robotnik took control of Mobius (by overthrowing the previous monarchy in a coup d'etat), he invaded the large city Mobotropolis using the robotic military that was supposed to have been dismantled after the war. The pristine and beautiful city was then transformed into an industrial wasteland, Mobotropolis became Robotropolis. It was the seat of Robotnik's power until his "Doomsday Project" was destroyed by Sonic and Sally using the power stones.

SatAM and Archie continuities
In the SatAM and Archie comics continuities, Mobotropolis had once been ruled by the House of Acorn, until King Acorn had been deposed by his treacherous War Minister, Julian Kintobor, who later adopted the sinister moniker of Dr. Robotnik. Julian was a trusted advisor of the king, but was evil at heart. The king, and the rest of the royal family, were sent into exile. As soon as Julian, who had now renamed himself as "Robotnik" (Kintobor spelled backwards) took over, he roboticized the citizens (as many as his army could get). (This, by the way would be the SatAM, Archie and Sonic Underground's tie in (one of only a few) with the games, as Robotnik is in "charge" of the Robots, although unlike the games, organic lifeforms in these continuities are actually roboticized, rather than "trapped" inside). Eventually, in Archie, Robotnik himself was deposed (by being wiped from existence when one of his latest weapons of mass destruction backfired on him), and the House of Acorn resumed power, restoring Mobotropolis temporarily to its former glory. However, the arrival of an alternate-universe version of Robotnik spelled disaster for Mobotropolis, which once again became Robotropolis. Robotropolis was destroyed in a nuclear attack by Station Square. The harmful fallout is currently kept within the former site of the city by a shield originally designed to protect Robotropolis. In the miniseries Mobius: 25 Years Later, Mobotroplis appears to have been retaken and managed to rebuild it as Rotor disembarked from a ship that had departed from Mobotropolis when he arrived on Portal, Angel Island.

Sonic Underground
In the popular television series Sonic Underground, the former ruler of Mobotropolis had been Sonic The Hedgehog's mother, Queen Aleena Hedgehog who has been said to be the rightful ruler. Sonic himself, along with his siblings Manic and Sonia, were heirs to the throne, and fated to one day form a council of four with their mother and take back control of Mobius.

In look and design, Robotropolis in Sonic Underground is exactly like it was in SatAm; however, in SU Robotropolis is still inhabited by Mobians, possessing a run-down slum for the underclasses and more upscale areas for the aristocratic elite.

Sonic the Hedgehog: The Movie
In Sonic the Hedgehog: The Movie (also known as "Sonic Anime"), Robotropolis is the massive techno-city constructed by Robotnik in the Land of Darkness and is near or in a post-apocalyptic city which resembles New York City, though Mobotropolis is not referred to and the name for the city in the Japanese version is Eggmanland. (It has been theorized that the name was changed to Robotropolis as a tie-in with the American continuity, like the reference to Princess Sally in the Sonic CD manual.)
