Zodiac's reunion with his long-lost brother was short and bittersweet (emphasis on bitter) when he discovered Scorpio had become a mass murderer and helped the police apprehend him. Imprisoned in a maximum-security prison, Scorpio swears he's innocent and was controlled by his evil ex-girlfriend, Hydra. But when Hydra breaks Scorpio out, Zodiac goes back to his killing ways...until an even deadlier enemy, who desires Hydra's power, intervenes, and threatens to destroy Scorpio, and Zodiac along with him.
