The Metropolis Zone is a huge, industrial city made entirely of pipes, mechanical contraptions, and huge factories controlled by Dr. Eggman. It also serves as an Egg Army base for Dr. Eggman's Metropolis Egg Army.
After defeating Dr. Eggman and his assistant, Dr. Julian Snively, at their base on South Island, Sonic the Hedgehog chased the two mad doctors down to Westside Island, where he teamed up with his new sidekick and best buddy Miles "Tails" Prower as well as the Knothole Freedom Fighters. They arrived in Metropolis Zone after passing through Oil Ocean Zone in their efforts to defeat the mad doctors, whose goal on Westside Island was major construction and refinements as part of their plan for world domination. From here, they chased them down in Sonic's biplane, Tornado, to the Wing Fortress. (VG: StH2, SSD: #12)
The Shattered World CrisisEdit
- From a reader's perspective, this picks up from where the original Pre-Super Genesis Wave continuity left off.
At some point, Dr. Eggman stationed a faction of his Egg Army in Metropolis Zone- the Metropolis Egg Army. Bunnie Rabbot-D'Coolette infiltrated the Metropolis Egg Army, which was working on a flying fortress to replace the Death Egg. After Sonic the Hedgehog and Tails arrived to retrieve her, they worked together to steal a Shield Generator for their new Sky Patrol base. They were opposed in these efforts by the Egg Army and Badnik Horde, but were aided by an earthquake that served as one of the forewarnings of the world shattering. (StH: #254, #255)
- The Metropolis Zone was a level from the game Sonic the Hedgehog 2.
