Metropolis is the central stronghold of Dr. Eggman in the video games and other media, such as the Sonic the Comic and Archie Comics continuities. This gargantuan machine-city is a polluted nightmare of steel and concrete, replete with robot sentries, Orwellian tele-screens, and free-flowing rivers of radioactive slurry.

For sixteen years (1992-2008), Metropolis occupied a sort of conceptual limbo in the game continuity. Although (as mentioned above) Megao/Metro/Robo/Mobotropolis functioned as Eggman's base of operations in most other Sonic media, within the games there was only the Metropolis Zone of Sonic the Hedgehog 2, which scarcely looked like a city, let alone the capital of the Eggman Empire. For over a decade, throughout the main series and spin-off games, Robotnik was shown operating out of mobile command centers or hidden research labs—with little to indicate that the Doctor still had a central stronghold. But a definitive answer finally came within Sonic Chronicles: The Dark Brotherhood, which revived the fortress-city as his base of operations.

Game appearances

Sonic the Hedgehog 2


Metropolis Zone in Sonic the Hedgehog 2.

Metropolis first appeared as Metropolis Zone, the eighth zone of Sonic the Hedgehog 2; coming after Oil Ocean Zone and preceding Sky Chase Zone. Unlike the previous seven levels, Metropolis contains three full Acts, and the stages are particularly massive—in some cases infinite, for in Act 2, the bottom of the level loops to the top! The boss of this zone is Flying Eggman.

Sonic Chronicles: The Dark Brotherhood

Sonic Chronicles: The Dark Brotherhood actually starts with the destruction of Eggman's Metropolis. GUN attacks the city in full military force, while Sonic, Tails, Knuckles and Amy battle the Doctor on board his latest Egg Carrier (which bears closest resemblance to the flagship, Final Fortress from the end of Sonic Heroes). Tails succeeds in sabotaging the Carrier, such that the airship disintegrates and crashes into Metropolis, devastating the city in a massive explosion as the GUN forces and the heroes escape from the scenery.

Following this defeat, and with Dr. Eggman missing and presumed dead,[1] the ruins of Metropolis were left to rust. The only visitors were those human scavengers brave or foolhardy enough to raid the ghost city for salvageable metals and technology,[2] until more guests began to arrive.

In Chapter 5, Eggman provisioned Sonic with the necessary information to infiltrate the Metropolis Underground and stop the Marauders. The hedgehog arrived seconds too late, though; after expropriating the Master Emerald from its plinth, the Marauders abandoned the stronghold and returned to the Twilight Cage—leaving Knuckles' floating continent to crash square into the city.

In the end sequence of The Dark Brotherhood, the team return from the Twilight Cage to find Metropolis entirely rebuilt - and bristling with weaponry. Eggman promptly shoots the Cyclone out of the sky in something of a cliffhanger ending.

In other media

Sonic the Comic

In the Sonic the Comic series published by Fleetway Editions, Doctor Robotnik managed to conquer all of the planet Mobius and establish a totalitarian regime. While in power, he would rule the planet from Citadel Robotnik in the Metropolis City Zone after moving from the Special Zone's Egg Fortress.

Metropolis City was a focal point for many of Robotnik's traps and surprises for Sonic (including the infamous Hero of the Year Award,[3] and the ridiculous Mister Blobnik[4]). Sonic and the gang visited the Zone quite frequently, attempting to disrupt Robotnik's rule there.

After the Doctor's regime was toppled in Issue #100 (thanks to an electromagnetic pulse generated by Super Sonic), the oppressed residents of Metropolis took back the city and razed Citadel Robotnik.

Archie Comics

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Metropolis Zone was initially a temporary location created by Eggman with the first Genesis Wave In an attempt to stop Eggman's plans for Mobius, Sonic infiltrated the Metropolis Zone to stop Eggman once and for all. When Sonic found Eggman though, he began to realize what Eggman had done to the world, and after a brief battle, the hedgehog cased after Eggman to the Death Egg Mark 2.

As a result of the Super Genesis Wave, the Metropolis Zone became a permanent part of Sonic's World. In Sonic the Hedgehog #255, Sonic and Tails infiltrated the Metropolis Zone once more, this time to find and rescue Bunnie D'Coolette. When they found Bunnie, who was undercover in the Metropolis Egg Army, Sonic, Tails, and Bunnie fought their way out of the Zone.


  • In Sonic Chronicles: The Dark Brotherhood, the map of Metropolis has a Sega Genesis, the Eggrobo from Sonic & Knuckles, the Drill Mobile from Marble Garden Zone of Sonic the Hedgehog 3, and the Capsule from the games from Sonic the Hedgehog 2 to Sonic & Knuckles.
  • The music of Metropolis in Sonic Chronicles: The Dark Brotherhood is a remix of Panic Puppet Zone Act 1's music from the Sega Saturn soundtrack of Sonic 3D Blast.
  • In Sonic the Hedgehog 2, the Metropolis was clearly located on West Side Island; in Sonic Chronicles: The Dark Brotherhood, it appears to be part of the same landmass as other locations in Sonic's world, implying that this version of the city is somewhere on South Island.


  1. Later in The Dark Brotherhood, the team learns that Robotnik was in fact saved and nursed back to health by one of his medical robots; he is eventually discovered, slowly rebuilding his power base from a secret underground facility in Green Hill Zone.
  2. As alleged by the adviser for the tower escalator puzzle, Sonic Chronicles: The Dark Brotherhood, Chapter 5
