Vanilla and her little sister, Chocolate, were devilish kitties that decided to torment the mortal world. They were diabolical in every way and brought death and destruction to the peaceful world of Greenhill Zone. They were an unstoppable force with their ferocious claws and fangs.
Coldsteel the Hedgehog
Origin
Coldsteel was born with a special power. As a child, he was always marginally stronger than all his classmates at his old dojo. He served in the military and soon retired to teach other young hedgehogs martial arts.
Cause
Once the kitties attacked his village, his old dojo was destroyed and Coldsteel discovered his sensei died in the claws of the kitties. He was very close to his sensei as a child as he was honing his skills. He became enraged and went back to the battlefield to fight against the kitties from hell.
Life
When he was in the military he trained harder than anyone to make sure his super strength didn't go to waste. He was deadly on the battlefield due to his superb martial art skills. He was highly honored throughout his subordinates and teachers. He soon retired to carry his experience to the next generation.
The Battle
The Global Greenhill military wasn't enough to stop the kitties. Coldsteel, a single hedgehog was able to put up a fight with even both of the kitties. Originally, he purely used his martial arts skills, but to beat them he needed an upgrade. He traveled to a legendary blacksmith and he obtained a katana and a revolver to have an edge over the kitties. Thus the years of fighting began between Vanilla and Chocolate, and Coldsteel.
