Let me get this straight. You think that your client, one of the wealthiest, most powerful men in the world, is secretly a vigilante who spends his nights beating criminals to a pulp with his bare hands; and your plan, is to *blackmail* this person?
Works for WayneTech Enterprises and a old friend of Thomas Wayne. Helps Bruce Wayne obtain advanced technology from Applied Sciences, a scrap zone for failed projects. Later, he is appointed to become CEO of WayneTech by Bruce and privately furthers research in Applied Sciences.
Lucius Fox was a briliant man who was extreamly knowledgable in regards to Waynetech. He also showed the ability to modify and even create many new technologies for Batman.
