I had some DA and Chaos spare parts in my bits box, so i've converted my own 'possessed by Khorne' version of Cypher:
He has a converted Chaos backpack that's identical to the official models 'winged icon' backpack (thanks to DA landspeeder bits)
He has a Plasma Pistol, Bolt Pistol, Chaos Sword case on his backpack with Hellblade sword handle sticking out,
The hooded head of Sammael (also from the said Landspeed bits).
A Chaos logo shoulder pad and a DA hooded skull shoulder pad.
Space Marine armoured body with DA hooded skull on a cross icon.
The legs of a BLOOD LETTER with various DA bits to look like robbed skirt and a chaos spawn tail.
...Trust me, it looks weird, but good.
The problem is, he's already undercoated, but i'm not sure on the colour scheme? Green armour/white robes or Green armour/Black robes?
Also how should I use him? With Bezerkers? With Cultists? Chaos Space Marines? or with my 5 man Chosen?
BTW yes my Chaos Space Marine army are Khorne based and no I don't care about the fluff logistics of Cypher working for Khorne or being turned into a hybrid-Blood Letter-Chaos Space Marine. :lol:
