When Darius was a young wolf, he tried to become a Freedom Fighter and join the Resistance. However, in a terrible turn of events, Darius is roboticized. He is left doing some horrible things, and no control over them. Once his brother Edmond, a child prodigy, finally fixes him, he has some mistakes that no one knows about.
Years later, Darius is only half roboticized and on a path to redeem himself, finally a Freedom Fighter in the Resistance. However, after a particularly sour morning, and a scheming Robotnik to reveal Darius for his crimes when he was enslaved and Roboticized, things take another turn for the worse.
