Max appears as a painfully normal human, but is actually an A.I. with a penchant for collecting strange, rare, and unique things.
Its unknown when exactly Max came into existence, but it was sometime after the second Matrix crash and the rise of the technomancers.
By those that know him, he is well known for his interest in unique and rare things. This interest has led the A.I to form contacts with several shadow runners over the years. Though not one to get involved with just anyone, those Max does take an interest in are certainly likely to be quite special.
