Team Babylon is one of the teams in Sonic Heroes 2. The characters in it are Jet the Hawk, Wave the Swallow and Storm the Albatross (from the Babylon Rogues) and Hurricane the Eagle (from the Babylon Five). Whilst not part of the main team, Tempest the Raven (the final fifth of the Babylon Five) looks after the Babylon-owned Scrap Brain, Star Light and Reactive Factory zones when the rest of the team are not there and is later of paramount vitality in the team's transportation to the Egg Carrier.
Their zones are races not dissimilar to those in Sonic R; Reactive Factory Zone remains as before, whilst Regal Ruin doubles up with Labyrinth Zone and Resort Island doubles up with Green Hill Zone. Radiant Emerald is right at the end on the Egg Carrier, but Radical City is tricky; it spreads from Metropolis, Oil Ocean Zone, north-east Aquatic Ruins, Casinopolis, south-west Marble Garden Zone, an otherwise impassable part of Mystic Ruins South and back into Metropolis.
The Babylon Five woke up one morning to discover that the parts Wave was intending to work with had been stolen. Jet, having previously been the recipient of a loss at Sonic's hands, points the finger of aspersion towards Sonic and JWSH make their way over to Green Hill Zone. Note: this is done automatically, and the cutscene literally goes from Scrap Brain to Green Hill Zone. Upon arrival, Team Sonic have arrived back from their venture in Great Turquoise Zone and are chased by JWSH, only for Hurricane to look elsewhere, lose concentration and quite literally fall off his board. Furious, JWSH take a trip home, only for them to run into Team Covert and another race ensues - in this instance, running away from Labyrinth Zone where they are. They decide that the only sensible solution is to return to Metropolis; they perform their usual route through Spring Yard Zone, Marble Garden Zone, through the Mystic Ruins train station into Station Square and then into Metropolis. Or rather, try to. There has been a terrorist attack on the city and the result is that the train from the Mystic Ruins to Station Square has been derailed and is stuck in Station Square; the result is that JWSH have to make their way through Marble Garden Zone (named Act Two by the game), through Casinopolis (much to the chagrin of the team, without playing any of its games) into Hill Top Zone, take a leisurely stroll through the scary sidewalks of Mystic Ruins South and a filthy venture through Oil Ocean Zone. Only then can they access Metropolis; however, having re-purchased the items, Team Dark shows up, with the original package clearly visible. Another race, this time around Radical City, ensues. With the parts obtained, an impressed shop-owner allows JWSH to use his back door outwards into Spring Yard Zone (this is also marked as Act Two). Through a different part of the labyrinth (Act Two), and through what appears to be a Star Light Zone considerably worse off than its original condition and into Scrap Brain Zone. But no, no peace just yet, as they discover Tempest and Team Eggman shooting quite savage breeze and a race ensues. With Team Eggman disposed of, the team return to Scrap Brain Zone. Tempest reports the discovery of a secret cavern on the Star Light/Scrap Brain/Reactive Factory border; while Wave makes the planned amendments, JSH investigates. It turns out that the cavern leads to an archaic transporter used by Eggman ≈20 years ago to access his old Sky Base Zone; in an attempt to return to Wave, Wave arrives and forks over the Gear. With the Gear in hand, the transporter is activated and JWSH are sent on their way on to the Egg Carrier. Upon arrival, JWSH locate further extensions which allow items to be levitated via the Gear, and this is used to dispose of Team Eggman, causing the Egg Carrier to descend very quickly.
