In addition to battling thousands of zombies, Frank West and Chuck Greene must also deal with psychopaths: humans who have either gone mad due to the zombie outbreak or are otherwise corrupt or evil. They serve as the games' bosses. They range from a children's entertainer who went insane after his audience was devoured, a deranged butcher who only sees other survivors as "fresh meat" and a pair of magicians who consistently kill their unwilling volunteers in their quest to become A-list performers.

Incidentally, not all of the "psychopaths" are genuinely insane. For example, The Convicts are a trio of criminals who escaped prison, commandeered a military Humvee and are simply taking advantage of the outbreak by causing chaos without having to worry about the police. The Looters are mainly just wanting to steal everything being that there is nobody around to stop them. Brock Mason is a cold-blooded career soldier assigned to contain the Willamette incident at any cost. Snowflake is simply a hungry Tiger, but can be rescued. Cletus, in a way, is just overly cautious and kills anyone who attempts to take guns from his hunting store out of the belief that other humans are just as potentially dangerous as the zombies. Ironically, upon his defeat, Cletus is terrified by Frank's perceived willingness to kill for the guns.

Sometimes, the game considers normal people to be psychopaths until defeated for the storyline. Isabela Keyes, for example, is entirely sane, but must be defeated by Frank in combat to get her to listen to him. Afterwards, she becomes an ally and plays a major role in the story.

NotesEdit

• Isabela, Cletus, Paul, Snowflake and Bibi are the only savable psychopaths. Though, Cletus can only be saved in Dead Rising: Chop Till You Drop.
• Throughout the series, Carlito, TK and The Convicts are the only psychopaths that can be fought more than once. Carlito and TK are fought in different areas during the story, The Convicts just respawn.
• TK's bodyguards are actually just different texture models of the Mercenaries.
• In Dead Rising 2, if survivors are the ones to hit the killing blow, the psychopaths show up as "Found" in the notebook, instead of "Dead".
• In Dead Rising 2, the psycopaths will dissapear even there is a cut scene showing where the exact spot where they died.
• In Dead Rising, survivors cannot kill psycopaths and Frank has to deal the killing blow.
• In Dead Rising, Kent and Carlito are encountered via cutscenes more than once. The Convicts are introduced in one cutscene but can be encountered multiple times.
• The Hall family from Dead Rising is about the same as the Hunters from Dead Rising 2, both being a group of snipers, being all men and none of them having a death scene but both have one opening scene.
• In Dead Rising 2:Off the Record,psychopaths bodies will remain in the spot where they died after the cutscene of their death like in Dead Rising.
• In Dead Rising,psychopaths weakness is melee weapon
