"Origin: Tokyo. An officer of the law who died on duty. He sticks to his sense of duty and patrols the streets in the name of justice. Without reason to hold him back, he doesn't hesitate to use his gun."
—Shin Megami Tensei A-Mode DDS dictionary
Shin Megami Tensei IV
"Police officers who have become zombies. They attack people regardless of whether any crime has been committed. They are supposed to be loyal public servants, but as zombies, they assault the very people they swore to protect. Due to their training in life, their attacks are orderly and deadly, and they are more than willing to put to use the fighting abilities that went to waste while they were alive. Threats of increased paperwork, pay cuts, or disciplinary action are all useless, as they are no longer government employees."
—Shin Megami Tensei IV profile
Zombie Cop cannot be recruited normally, he must either be taken as an ally from begging for his life, or recruited using the Scout+ app by recruiting one of the demons with him during combat, causing him to volunteer when Scout+ is invoked. He has an entirely unique set of dialog when he speaks. His basic attack is a gun rather that the usual physical strike. Zombie Cop can teach Flynn the Shibaboo skill through his Demon Whisper.
Shin Megami Tensei IV Apocalypse
As in the previous game, Zombie Cop cannot be recruited with the Scout skill, he can only be obtained as an ally by making him beg for his life or by volunteering to join when Scout+ is triggered when recruiting a different demon alongside him in combat. He can also be obtained through DDS Streetpass fusion.
Zombie Cop can be found within the Toyosu Shelter and the Konganji Passage within Ginza. He can teach the Cough, Rapid Needle and Panic Voice skills through his Demon Whisper.
Megami Ibunroku Persona
"An original demon in Ibunroku. A uniformed police officer turned into a zombie. Although zombies in general aren't very intelligent and can't use tools very well, Zombie Cop is a troublesome foe as it retains knowledge on how to use a gun. The concept of a zombie police officer is so popular that an American movie with the same premise called Zombie Cop was released in 1988."
