For the legs I used a pair of regular Chaos Space Marine legs. For the head I wanted something special. I tried converting a head out of a zombie head but it did not look right. I dug around in my bits box for a bit and eventually found one that suited this model.
The head I chose is off of the old chaos mutations sprue. He has blindfold around his eyes and his mouth/nasal area look exposed.
Next I will show you a work in progress picture of his paint job.
