Below is a pic of the Khorne Lord I converted to have a Bloodfeeder Daemon Weapon. I used Khorne Berzerker plastic legs with a Forgeworld torso conversion set I had leftover from squad. The Bloodfeeder is actually an inquisitor scale chainsword I had a bag full of laying around that I had forgotten about. The hands holding a sword were the hardest part of this conversion and still aren't as straight as I wanted but not really noticeable. I like the Bloodfeeder chance at lots of attacks, even if he'll probably roll a 1 everytime. When I do use this guy he's gonna ride in the landraider the Kharn and 8 berzerkers.
Below is a pic of Kharn the Betrayer that I built from a terribly painted and built model I got for a few bucks on ebay. Had to sit in Simple Green for a week to get stripped and couldn't even salvage the right arm, so had to use plastic replacement. He'll ride with the Berzerker squad in the Landraider.
