Only son of a section manager, for a faceless corperation, he went to school and grew up like any other beaver-brat.  That was, until, his parents were imprisoned for embezzling funds.  Derrick Masterson was placed into foster care.  After a year of home hopping, Derrick grabbed as much money as he could carry, and headed for the big city.  Once arriving in Night City, he quickly fell victim to the street.
 Having no one to help him, and being inexperienced at urban survival, he soon fell in with a small local juvie gang.  Here he experienced a brotherhood of pain.  Avoiding cops and rumbling with rival gangs [in the combat zone] became his life.  His initiation included firing on a police squad and a classic ritual beating [in which he seriously injured two of the blood boys].  After which, he got his first dose of the metal.
 In the middle of a smoggy summer, a rumble had been organized with the rival gang.  However, Derrick was betrayed & abandoned.  He found himself forced to fight ten rival members, solo.  Barely escaping the immense beat down he’d recieved, Masterson found himself running from a lot of people for a time.  After healing up a bit, he stumbled across an arms bust and swiped some C-6.  He planted this in his gang’s hideout and blew them all to nothing more than memories.
 Tired of wasting his time in meaningless rumbles, Derrick realized he was destined for something greater.  Lacking the technical knowledge needed for netrunning and tech work, and not charismatic enough for the spotlight, he found himself with option of becoming a street samarui or being carrion.
 So taking all the money and gear he’d acquired and stashed in his own cache, he set out to make a name for himself, always holding close, the last picture he had of his parents.  Having picked up some tips on the street about his new career, he realized his desperate need for an alias...and BLASTER was born.
 He got minor job offers, paying barely enough for minor add-ons and medical care(which was often).  In a matter of months, his metal gear was worthless and he was starting to run low on euro.
 On an autumn evening, while hanging out at The Afterlife, Blaster found himself in a brawl with a nasty cybersolo.  Bruised and badly beaten, he was on his last legs, when SHE walked in.  She was a 5’ 10” southern belle.  With a few quick, well-placed blows she pulled Blaster’s “ worthless hide outta th’ gumbo”.  She introduced herself as Daisy “Shade” Rae.  She had a short, hot-pink, punk cut.
 “You’ve got potential, your just undiciplined.  If we worked together, you could get more experience and we could both make a fortune!”
 Originally starting out as a buisness partnership, it quickly became deeply romantic.  For two years the couple fought and rested side by side.
 Blaster’s world crashed around his ears when he came back to the apartment cube and found the place a mess, and Shade missing.  Blaster spent the following year searching for Shade, and following in his interpretation of her methods.  His efforts proved futile as lead after lead turned up nothing.
 Having decided that she was lost to him, Blaster picked up a contract with a new employer.  However, upon learning of his true plans, Blaster gathered and copied all the available evidence he could get his hands on and exposed his employer’s plans to the entire local area.
 It wasn’t too long after this that Blaster’s carrer really started to pick up.  Blaster recovered some lady’s cyberhand from a corp.(Using stealth and brains instead of firepower)
 This was soon followed by Blaster’s inadvertant partnership with an up and coming rocker known simply as Roxxon.  Thrown together by neccessity and coincidence, Roxxon and Blaster joined together to fight a pair of unseen, alien foes.  In this fight, Roxxon and Blaster joined with an unknown techie who provided the duo with a tracking device.
 In the final confontation Roxxon threw the fatal blow, in the form of a kilo of C-6.  This brought with it a terrible price, Roxxon lost his leg to the blast.  Blaster’s arm was badly damaged, and considering the amount of money he had, considered it an oppurtinity to increase his power.  Going down to the ripperdoc’s he bought himself a heavy duty arm with kevlar covering, hydrolic rams, reinforced joints and a micromissile launcher.  The battle was later covered up by the FBI.
 From then on, Derrick has assumed a new, and current name of Trax.
 Having spent more time on the street, he has hearned how to stay inconspicuous.  To this end, he has totally redone his body, abandoning the bulky and obvious metal for more descrete circuitry.  He has never stopped looking for his lost Shade, and is willing to do anything to find her again.  Everynight, before his plastic eyes, he sees her face...and wonders.

Update:
 Trax has managed to rediscover Shade.  She was bound up in a contract with Biotechnica as a hired gun.  She had no way out, except through her own demise.  Through clever planning, Trax murdered Shade infront of Biotechnica execs.  He ran off with her body to a waiting ripperdoc with a Gemini body.  her brain and required organs were successfully transplanted to the new body.
