Station Square

Station Square is a fictional city, and one of the three "Adventure Fields" in the game Sonic Adventure and its enhanced remake, Sonic Adventure DX: Director's Cut.

Station Square is famous for its many attractions, including an amusement park (the Twinkle Park level) a hotel/restaurant, and a casino (the Casinopolis level). An elevator also leads to the Speed Highway level located above the city. A train station in the city allows the player to take a train to the Mystic Ruins, while a boat allows them to reach Eggman's crashed Egg Carrier.

Story
In the beginning of Sonic Adventure, Sonic goes to Station Square for fun, and stumbles across Chaos, a strange creature that is wreaking havoc is the city. Sonic defeats it, and later learns that Doctor Eggman had released Chaos and is planning on collecting the seven Chaos Emeralds to transform Chaos into an incredibly powerful beast that can destroy Station Square, so that Eggman can build his Eggmanland on its ruins.

Sonic and Tails goes after the Chaos Emeralds in order to stop Chaos from obtaining them, and one was found in Station Square (in Casinopolis, to be precise). Station Square also plays a role in the other characters stories - Knuckles finds three pieces of the Master Emerald there, Amy lives there, and Big and Gamma both go there looking for Froggy.

Eventually the heroes face off against Eggman on his Egg Carrier, and defeat him and Chaos. In a fit of rage, Eggman fires a gigantic missile into the heart of Station Square, but it turns out to be a dud, and Tails manages to get to the missile and deactivate it completely.

However, Chaos later manages to obtain all seven Chaos Emeralds, and transforms into "Perfect Chaos". Perfect Chaos quickly destroys Station Square by flooding it with a large tsunami, and proceeds to roam around the broken buildings sticking out of the water. Super Sonic manages to defeat the beast, and leaves the destroyed city.

Its current state is unknown, and it has never been revisited in later games. However, Rouge the Bat references it in Sonic Adventure 2 when Eggman asks her where the last Chaos Emerald is. Rouge takes out a newspaper article that states that Tails was rewarded with a Chaos Emerald at Station Square's city hall for saving the city from the missile. This may suggest that the city was rebuilt, or at least not completely destroyed, although he could just as easily have been rewarded the Emerald before Chaos destroyed the city.

Casinopolis reappared as the location where Sonic Pinball Party's Story Mode was set.

In Sonic the Hedgehog (Archie comic)
In the Archie-published Sonic the Hedgehog comic book, Station Square first appeared in the Sonic Adventure adaptation where it was previously known as the "Hidden City of the Ancients". The city is hidden in a mountain with a plane sticking out of it located in a region of Mobius called the "Mysterious Cat Country". It is the only place on Mobius that humans (not "Overlanders", special four-fingered humans) inhabit. The only visitor prior to the arrival of the Knothole Freedom Fighters and Dr. Robotnik was Nate Morgan.

In issue #162, Snively stated that Station Square has expanded and had become part of the "United Federation", which is made up of all the Overlander cities and inhabited area's on Mobius. The United Federation's capital is Station Square, and their large military is known as G.U.N. Recently, in issue #166, Casinopolis opened in Station Square. It was operated by Renfield T. Rodent who was working for Robotnik, and the casino was nothing more than a way to scan the minds of the citizens in order to replace them with Infiltrators, but the plot was foiled by Knuckles, Rouge, and the Chaotix.

In Sonic #110 it is revealed that Station Square has a defense system known as OTIS (The Outer Threat Immobilization System) but when the Station Square government inputs the tactical data on Robotnik given to them by Princess Sally (Sonic #106) the system switched it's command protocols from defense to offense and launched a nuclear strike against Robotroplis that destroyed the city.

In Sonic X
In the anime series Sonic X, Station Square is the home of main human character Christopher Thorndyke. This was the location that Sonic X took place on for Season 1, (in the Japanese version, in the English dub they were Seasons 1 and 2) where Sonic, Tails, Knuckles and the other characters were sent to. Instead of being completely destroyed and never seen again after the Sonic Adventure adaption, the President of the country signed bills for the whole city, mumbling about why he couldn't be a hero as well as Sonic.

Trivia
