An interesting character. The depiction is obviously one of a thief (all the watches up his arm) and a down and out (his dishevelled appearance). Yet, he rubs shoulders with the rich and powerful, controls a train (transport) and is untouchable in his own domain. He ships stuff in and out of the Matrix for the Merovingian, including stuff that does not belong there.
He is, of course, a drugs trafficker, arms dealer and smuggler. He is seen, by society, as the lowest of the low, yet is very powerful and deals with the upper echelons of society. He’s the arms dealer that does deals with presidents and prime ministers. He is the drugs dealer that supplies movie stars and politicians. He is the guy that can provide that illegal artefact, made from an endangered species, for the high end business executive.
