|"Even though it sounds like this guy was named after someone's childhood teddy bear, Jojo is a whole lotta mean dressed in gang colors. The only time you'll see him talk things out with a woman is when he doesn't want to mess up the merchandise before she goes out on the street. Violence is his sole method of debate.
Now, that may not be his fault. He may have had a troubled childhood that taught him to distrust anyone in authority. It may be his pent-up rage at himself and the injustices of the world that causes him to lash out for control and attention. That's all very well and good for people who care about that kind of thing... but wherever they are, it sure isn't Hell's Kitchen. As for as the rest of us are concerned, he's a thug and a pimp and a felon. Moreover he's armed and dangerous. It's time to start a countdown."
|- description of JoJo Fine, Deus Ex|
Having deluded himself into believing that he is a highly feared and respected gangster, JoJo has become intolerably egotistical, threatening physical violence and even death to those who would dare question his authority. JoJo is also a NSF officer, due to the manpower and knowledge of Hell's Kitchen he is capable of providing to its cause, as the NSF command favor sending JoJo's thugs on high-mortality operations in place of their own troops. JoJo is more than happy to supply the NSF with his men, provided they continue to pay his asking price in return. Due to his mercenary nature, criminal background and lack of even the slightest semblance of moral integrity, JoJo is despised amongst his NSF colleagues and is tolerated solely due to the fact that the actual NSF forces within Hell's Kitchen are already spread too thinly to coordinate effective combat operations against UNATCO forces in the region. Capable of providing the manpower necessary for the defense of priority sectors, JoJo is tasked with the command of the NSF's generator facility, receiving generous financial support from Juan Ivanovich Lebedev for doing so, much to Lebedev's chagrin.
When the generator facility is raided by UNATCO's forces, JoJo abandons his men, leaving them to die in defense of the doomed facility as he flees to a secure location to cower for his life. After JC's defection, UNATCO alters its priorities, dropping their ongoing pursuit of remnant NSF operatives in New York in favour of hunting down and eliminating Denton instead. JoJo takes this opportunity to sever ties with his NSF allies, instead focusing on his "career" by returning to criminal activity. After slipping out of his original hideout at the Osgood and Sons Warehouse prior to JC's arrival to the city, JoJo forcefully occupies the 'Ton Hotel, Paul Denton's former residence. JC, feeling obliged to assist Gilbert Renton for the continual hospitality and generosity he provided for Paul, intervenes in the situation. Depending on the player's actions and response time, JoJo may be knocked out or killed by the player during the subsequent conflict following interaction with JoJo, although the player should be aware that one of, if not both, Gilbert and Sandra Renton may also be killed during the ensuing firefight. It is possible to kill both Gilbert and Sandra Renton before JoJo talks with them, which allows JC to converse with him.
- JoJo has the same character model as Louis.
- A female Rooks gang member may ask JC "Who sent you, JoJo?" if bothered. This can be a clear proof that JoJo belongs to the gang, meanwhile being hired by the NSF.
There's a map loading glitch that can cause two JoJo's to appear.This can be done by killing the Rentons first, than waiting for JoJo to go downstairs. Ignore him and exit from the hotel in any way, causing another map to load. Enter the other loading zone back to the hotel (if you get out of the door get in through the roof) and two of them will be at the reception.
