In the far east lands of Mobius, the Kingdom of the Sun is divided into 4 countries ruled over by warring Shoguns battling for supremacy, with an Emperor who stands above all else.
Fleetway Robotnik, otherwise known as the Purple Rhino is one of the most formidable of all the 4 Shoguns. He rules over the cities and towns building towering wonders that reach high into the sky, along with new weapons taken from Shogun Julian and expanded upon. Despite his ability to bring jobs and innovations to small towns he is considered the most cruel of all the 4 Shoguns. All that dwell under his protection are forced to work as slaves building endless tribute monuments dedicated to him, with half of everything they own is taken from them as taxation. To keep his kingdom growing many citizens are often spirited away from other places beyond his borders and forced to start new lives under his rule. Any who dare resist or show signs of disloyalty disappear into his dungeons and never seen again.
