Robotropolis is the capital city of the Robotnik Empire. Much like the rest of the Empire, Robotropolis is run through fascism, under the dictatorship of Dr. Robotnik. The streets are mostly filled with robots, and Mobians were harshly treated. Mobians often faced injustice and discrimination in the city, with many being immediately thrown in custody without parole, families separated from each other, and those who tried to escape being beaten to death. The city is comparable to a giant factory; it's a breeding ground for roboticized Mobians, and a place where SWAT-Bots are being manufactured through roboticizers. It's also where they were being made specifically to put an end to Sonic and the Freedom Fighters' goal to overthrow the Robotnik Empire.
The dictator of the Robotnik Empire, Dr. Robotnik is a mad scientist who originated from Earth before being transported to Mobius. With the robots he created from the US Navy officials he killed, he took over Mobius to build a new empire, and claimed Mobotropolis as his own.
