The Man from Z.O.M.B.I.E

The Series

It is 1962. A secret war is being waged within the Cold War between the agents of Z.O.M.B.I.E. (Zero Organic Members of the Bureau of International Enforcement) and its rival, P.U.R.I.T.A.N. (The Peoples Union for the Reclamation of International Terror, Anarchy and Nihilism). These opposing Deep States contend for global power by any means possible — even weaponizing the newly dead. Z.O.M.B.I.E. wishes to preserve the autonomy of nations to decide their own destiny; P.U.R.I.T.A.N. wants to cause chaos and anarchy as a pretext to bringing about their own order at the cost of jackbooted tyranny.

Agent John Seven is one of Z.O.M.B.I.E.’s newest weapons: a “Zero agent”, a man brought back from the dead to serve his cause unquestioningly, without pain, without hesitation, without end. He is built to be a machine, but Seven is plagued by dreams and images of a life he once had. Weaponized corpse to some, zombie to others, his mission objectives also include suppressing an appetite for human flesh.
