"A Game of Cat & Mouse"
*Keith Greyson is a veterinarian who is transformed by a lab explosion into the fur-covered Demon. He receives fantastic agility and fighting abilities, but simply wants to keep his office open and his abnormality a secret.
Cat and Mouse are two underworld operatives who are in the employ of the Yakuza. The Yakuza find them expendable in their struggle with the Mafia for control of the City, and Mouse ends up catching a bullet. Cat finds that the only medical help that he can find is Greyson. In an uneasy deal, trading secrecy for unlicensed medical treatment, a team is formed.
