"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."
"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 precise 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 can not 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 is notable for having an entirely unique set of dialog when he speaks. His basic attack is a gun rather that the usual physical strike.
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.
