Joe Ferro is a former sanitation worker and the founder and leader of the Cleaners. His headquarters is where they make the Napalm-B that the Cleaners use to fuel their flamethrowers. He is killed by Division agents who storm his headquarters.
Before the outbreak of the Green Poison, Ferro lived and worked as a sanitation worker with his wife in Manhattan. He liked to call in to live radio broadcasts. When the outbreak happened, his wife succumbed to the virus. In response, he founded the Cleaners and became a psychopathic pyromaniac who believed that the only way to destroy the virus is with fire.
He is a misguided antagonist who thinks he's a hero. Ferro believes that the only true way to ensure the destruction of the Green Poison is to destroy any object or person that may be infected. He believes that this is the only way to ensure the future of humanity and that the current authority is too soft to carry out what needs to be done.
Ferro will kill anyone to complete his goal. His psychosis is most likely due to the fact that his wife was one of the first victims of the epidemic.
Joe can be seen wearing a custom cleaner suit, consisting of much larger napalm tanks, the suit is yellow in contrast to the typical red that Cleaners wear.
In a phone recording, it is revealed that Joe has a niece of which he deeply cares for.
When the player is storming the Napalm Production Site, he addresses the agent(s). In a way, he seems to understand the player might be from the federal government, but also tells the player to turn back as he and his cleaners are doing what they believe the player and the government aren't "brave" enough to do.
His death does not affect the cleaners as much as other factions losing their leaders. The cleaners, unlike the other factions, have a goal that merely requires them to continue destroying the virus and contaminated objects.
While the loss of Ferro's Napalm Production Site hurt the Cleaners' dream of achieving maximum force, his continued quest to unlawfully eradicate the Green Poison would live on through the rogue agent Vivian Conley.
Before the outbreak, Joe Ferro was most likely a normal individual who likes to call into live radio broadcasts. He also seems to be very caring and loving to his family and was deeply effected by the death of his wife from the Green Poison. He deeply cares for his niece (who lives outside of New York City) as one of his reason of forming the Cleaners is to make sure the virus gets destroyed in New York and doesn't spread outside as he fears she (and others) might contract it as well.
During the early stages of the outbreak, Joe believed the situation was going to get worse and was frustrated that the sick were not going to the hospital and government's lackluster response. He expressed his thoughts radio broadcast in a Cleaner report.
After the death of his wife and the JTF's inability to handle the crisis, Joe became much colder than his former self, believing the only way to eradicate the virus is to burn any trace of it, including infected people. Thus, he forms The Cleaners with many other sympathizing sanitation workers. Joe seems to acknowledge that he and his factions' methods are morally questionable (and thus are marked as enemies by the JTF), but nonetheless believes he and his fellow cleaners are simply doing what needs to be done for the greater good.
Joe is also shown to be hard-working individual who is committed to a cause and treats his fellow cleaners as equals despite being the leader. Several Cleaner report shows he motivates his fellow cleaners to continue their work, calling them heroes, and gave a eulogy to a fellow cleaner who died for the cause and motivates other to follow in his footsteps.
He's known to also go out in the street to get the job done, a trait his fellow cleaners admire and respect. During the boss fight, he expressed his desire to fight side-by-side with his comrades against the Division agents and was irritated when he couldn't because one of his men was having trouble strapping on his fuel tank.
Joe is a stronger variant of the typical Incinerator class enemy. His only weapons are firebombs and his flamethrower. When the player is too far away, or when a turret has been placed, Joe will run up and attack when in range to use his primary weapon. As with other Incinerators, he has three fuel tanks that can be shot and detonated- that will take a good chunk of his armor and health. His flamethrower's range is pretty far, so don't be fooled, run away when he's close, and take cover.
“ Listen up, whoever you are. I'm guessing you're Feds but really, it don't matter. You're doing the wrong thing, and you're gonna die because of it. The men you're facing, they're here to do what no have the stones to do. They could have left. They could have gone to their families. But they stayed to burn this thing out, to make sure it got stopped here. They sacrificed themselves, and then you - you come along and try to fuck it all up, because you're not hard enough to do what's gotta be done? It ain't gonna work. My boys are better than that. And we're gonna this thing through over your. Dead. Body.- When Division agents are entering the final section of the Napalm Production Site to go against Ferro ”
