Stardust Speedway (星くずのサーキット Hoshikuzu no sākitto?, lit. "Stardust circuit") is a location that appears in the Sonic the Hedgehog series. It is an urbanic region on Little Planet that was once conquered by the evil Dr. Eggman when the planet arrived on earth, but was eventually freed. It is best known for being the site of the first clash between Sonic the Hedgehog and Metal Sonic.
Stardust Speedway is a city located in Little Planet, between Palmtree Panic and the Wacky Workbench. It is notable for its light colors during night. Numerous golden highways adorned with instruments, signs, gimmicks, and Time Warp signs, are also into the city, while some gorgeous buildings and lights are seen in the background. What appears to be a factory under construction is seen below those highways. Somewhere in the city, a Dr. Eggman-themed statue can be seen.
In the past, it used to be a Greek/Roman-styled city with vines in the highways near to what appears to be a lake. It also used to have a palace in the same place where the Eggman-styled statue is currently located.
When Dr. Eggman re-wrote the future to his own image, the city was the same as in the present, but it was polluted, ruined and full of crime, while some red storms were constantly destroying the place. The highways seemed to be rusted and their instruments were almost completely destroyed. Also, the statue was now totally finished. A grey amusement park also appeared here, but it didn't seem to be working. After Sonic the Hedgehog re-wrote history, Stardust Speedway was no longer a city, but an amusement park, as far as the eye can see, in a bay full of lights, colors and attractions, where fun and leisure dominated the place. The statue has also been replaced by a cathedral/castle that suited with the rest of the park.
Stardust Speedway once used to be a Greek/Roman-styled city near a lake. Over time however, it was turned into a modern and colorful city.
Sonic the Hedgehog CD
In Sonic the Hedgehog CD, Dr. Robotnik invaded Little Planet and its regions, which included Stardust Speedway. He installed robot teleporters in the past and infested the city with Badniks. He also put some Metal Sonic Projectors to terrorize the animals that lived there. With this, he managed to conquer the future of the planet and write history to his own image. In Stardust Speedway's case, however, the city ended being ruined as a result of the constant storms there caused by the pollution in the planet.
When Sonic the Hedgehog arrived into the planet, he started to get the Time Stones and re-write history in Little Planet, reverting Robotnik's effects in Stardust Speedway. After Metal Sonic kidnapped Amy Rose in Collision Chaos, Robotnik left her tied somewhere in the highways, and waited for Sonic to show himself up to rescue the girl. After Sonic arrived, fixing the future and turning it into a amusement park, Metal Sonic challenged Sonic to a race, with Amy being the end of it. The hedgehog won, destroying Metal Sonic and freeing Amy. The hedgehogs later left Stardust Speedway to defeat Robotnik in Metallic Madness. After this, Little Planet was definitely freed from Robotnik's control, leaving Stardust Speedway to have a peaceful destiny.
In the console/PC version of Sonic Generations, using the Time Eater, Modern Eggman restored Stardust Speedway, leaving it in its ruined state again and under his control. There, Classic Metal Sonic challenged Classic Sonic to a battle. After the hedgehog won, the robot gave him a Chaos Emerald.
After the Time Eater was destroyed, Stardust Speedway was presumably restored to its "good future" state.
Sonic the Hedgehog 4: Episode Metal
In Sonic the Hedgehog 4: Episode Metal, a monitor from Dr. Eggman was taken to Stardust Speedway to reactivate a not-working Metal Sonic. After the doctor succeed, he told him to return to the earth, where he would repair him. No explanation has been given of why does Stardust Speedway appear in its "bad future" state in this game.
In other media
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Stardust Speedway Zone was an area within Collision Chaos Zone - a Zone created by Dr. Ivo Robotnik and used as a trap for Sonic the Hedgehog, in which Amy Rose served as bait. In Stardust Speedway, Sonic raced and defeated Mecha Sonic so he could save Tails and Amy.
After the Super Genesis Wave rewrote reality, Stardust Speedway became much more similar to its game counterpart, being a Zone under Dr. Eggman's influence on Little Planet and having the same role it had in the games.
- Stardust Speedway is one of the Zones with the most different versions of its music that are all remixed from the tracks of its debut game, mainly the bad future themes of both JP and US soundtracks.
- In Sonic Generations, there are two versions: the default Metal Sonic boss theme (a remix composed largely of the bad future JP theme, and a bit of the present JP theme), and an unlockable track listed as Stardust Speedway Zone (a remix is based on the bad future US theme in Sonic CD).
- In Sonic the Hedgehog 4: Episode II, another remix of the JP bad future theme appears in the Metal Sonic race in the Death Egg mk.II Zone, which also incorporates the new arrangements brought in from the track used in the Metal Sonic boss fight in Sonic Generations.
- In Sonic Mania, there are three versions; the theme in Act 1 is based on the Past version, Act 2 is based on the Present and Good Future versions, and the Metal Sonic boss theme is based on the bad future version, all of them based on the Japanese soundtrack.
- In Sonic Forces, the Metal Sonic boss fight features a remix of the bad future version from the US soundtrack.
- In Team Sonic Racing, a slightly sped-up remix of the theme used for the Metal Sonic boss fight in Sonic Forces is used for Metal Sonic's Team Ultimate theme.
