As promised, here are some pics of the Khorne Raptor squad in all it's winged glory.
To his right is my special weapons guy. He'll either be a melta or a flamer, depending on whichever I want to run. The possessed arm with the flame shooting out makes it work well for both, I gather. Instead of red flame I'm considering using green flames for contrast. He's on the ground as well clearly looking at what he's burning down in front of him. His close combat weapon is held at the ready.
The raptor on the right is using a piece from the Chaos Warriors set for his right arm. I imagine he's jumping toward his right, the reason his feat and head are turned that way. His sword is bring brought up to block an attack, and his left "hand", another possessed arm, is pulling back readying for a swift piercing attack.
Of course, what would Khorne be without some guy going all akimbo style with two pistols. I love this pose on my 'Zerkers, and I've used it before. He may not be raging like the other guys, but I see him using his two pistols like weapons themselves, blocking attacks and slamming the muzzle under an Imperial fool's chin and pulling the trigger.
