Category 0 was a proposed category of the categories of life system instated in light of Miracle Day, which resulted in the human race becoming immortal for several months in 2011. (TV: The Blood Line)
Category 0 would consist of any person, of any category, deemed fit for incineration in the modules for moral reasons, such as criminals who would have received the death penalty prior to the Miracle. (TV: End of the Road) Rex Matheson unwittingly predicted this category after learning of the categories. He believed that after starting with the Category 1s, it would move onto convicted felons and illegal immigrants, "hell, anyone we don't like." (TV: The Middle Men)
Oswald Danes later learned from Jilly Kitzinger that he had been classified as Category 0, after which he went underground; Jilly implied that the category had been specifically created with Oswald in mind. (TV: End of the Road) Oswald, who had been convicted for the rape and murder of 12 year old Susie Cabina, survived his execution by lethal injection as a result of the Miracle. (TV: The New World)
