Quote - im thinking he has a chain sort of weapon inside his body and can slice and dice anyone he comes across  my problem is witch 3d program to do it in and what else can i end to make it look  unique

First of all, which programs do you use? And secondly I would work on giving the character a bit of a back story first and sketch some concepts. This will help you gain more of an idea as to what the character will look like. If you give the character 'purpose' it will help you make choices such as clothing, build, weapons etc that will make more sense in the end.
