His world is very like ours (exept they dont look anything like us!) He grew up in a bad part part of th world where all the gangs are and he happend to be in a terrible accident. He had a fight with one of the kids from his school, but the thing was that he was part of a leathal gang which decided to punish him!A gang of around 30 men crowded round him as he was walking home one day and beat him up! they had hit one arm so hard and so much that it had to be amputated! another difference they have to us is that they are ahead in their technology and were able to replace it with a robotic arm!
