Hoping to harness the demon's power for soldiers, the government combined blood of the demon with Patient X's blood, thinking they could extract the Krychek's powers into a serum that could be used to imbue soldiers with the power, making them stronger and impervious to weapons. The serum was then injected into Patient X but there was no reaction causing the government to quickly shut down and abandon the project, returning the Patient back into society.

Although the Patient remained unaffected, the Krychek developed a Virus that was spread to various magical beings including other demons and a friend of the Charmed Ones, Billie Jenkins.

After Billie was infected with the Virus, the sisters sought an antidote to save her and went to [{Agent Murphy]], an employee of Homeland Security. He informed them of the project and they realized that Patient X wielding the antidote for the infected in his blood.
