"We are the tarnished blades, the scorn of our society. They created us to fight their battles and tossed us aside as though we were as low as their waste. I will show them the error of their ways and teach them the true definition of power! Join me brothers so that we may claim our rightful place in this world. We are no longer man, not quite Pokemon, but something in between... something far more powerful." - Nero

After the end of the war between Azure and Crimson, their weapons, the pokemorphs dubbed chimaera, were cast aside, treated as lowly criminals. Nero, however, refuses to be treated as such, and plans a great revolution to bring honor to his brethren. Fight alongside him... or against him.
