Metropolis makes an appearance in Sonic Heroes 2. Like Scrap Brain Zone, it has been disused by Eggman and has had another design plastered over the top. Here, it is a big commercial estate/market based on Merton High Street, with the large Sainsbury's/M&S being 'chucked out' and converted into a Chao garden. Here, salesmen pitch stalls outside their houses and sell things - parts, flowers, tools, monitors and, in Team Babylon's case, Gear upgrades. Some may ask for favours (taking things to other destinations such as Station Square) or others may recognise you for who you are and start a fight (always between teams). Covert is said to frequent here at night due to the stall owners' leaving things on their stalls. However, for obvious reasons, this remains undivulged outside of Team Covert's storyline.
- Both this zone and Station Square, the two main shopping zones of Sonic Heroes, are both based very heavily on Wimbledon despite the author living two postal districts away from it in SM3; Station Square is based on Wimbledon High Street and Metropolis is based on Merton High Street.
