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.

I would suggest deciding how it is attached inside and how it is deployed, that might lead you to concepts regarding physical attributes and complications ie:
*is it coiled in his stomach...if so what happens when he eats etc
*How is it deployed? through a flap? In one loop or sections? (as in one of spidermans' villans Dr octopus) does he swing it around like a mace or does it strangle like a python? (or both)

Is it an intert object or is it alive? does that work with or against your warrior?

*what weaknesses do your decisions infer? Water & Rust? does he sink in water? does it need maintinence? Can it be rendered ineffective by magnetism? These all add a twist like Kryptonite that gives your game a bir o f spice...smile

Also in mention to the back story, is it a weapon he has had inerted (voluntary/involuntry) or was he born with it?

What training did he get to use it ie: military so he is profficent and effective, or taught himself os he is rahter erratic but effictive.

I would say use a program you are familiar with to start with and explore from there.

have fun.

Before you get into modeling something like this, I think  you probably need to get familiar with what game engine it's going to go into and what constraints it has, how its rigging works etc.
