Sonic blue sky

It is 2087 at the planet of Mobius at the megacity of Hydrocity. An enormous city once famous for its waters, rivers, and beaches. Also, for its giant port to which the United Federation considers it very important for its export economy. Once considered to be the economic and social capital of mobius.  *The current state of the city is a mess. Suffering immensely from crime, corruption, pollution, and mostly from the "unofficial" monopoly that bought almost all of the properties. We follow the story of Sonic, the hedgehog and his group that he calls "Blue sky." They fight against the tyranny of Robotnik and other factions to protect his city and his friends.*
