Station Square was threatened by Dr. Eggman after he unleashed a life-threatening missile attack on it. However, Miles "Tails" Prower managed to save it and was given a Chaos Emerald as a reward by the mayor at city hall.
Station Square reappears in Sonic Chronicles: The Dark Brotherhood as part of Blue Ridge Zone. People watched as Sonic and his friends landed the Tornado there and it housed the citizen worker Johnson with a large factory near it where he works.
In Sonic X, it is the home of the human Christopher Thorndyke and his workers, Ella, Edward Tanaka and Chuck Thorndyke, as well as his friends Danny, Francis and Helen. It was levelled after the attack of Perfect Chaos, but Super Sonic defeated the beast and the President signed bills to have it reapaired.
