I have been debating on whether or not to start a demon army for awhile. Except that it will be an Undead army. The rules are perfect for the type of Undead army I want to run, which is an "otherworldly" type of Undead as opposed to the normal ghosts, skeletons, zombies, etc. Basically creatures straight from the Netherworld and their supporting forces. The one thing that has stopped me though is that I already have 2 armies that I need to finish painting and I really don't want to have build and paint another one.
But, I saw some new Rackham models that are coming out within the next month or so, and since they are pre-built and prepainted, problem solved!
This could be some sort of Slaanesh or Tzeentch Herald or Demon Prince.
The female could be used also as a Tzeentch of Slaanesh Herald or Demon Prince, with those in the background counting as Bloodletters.
The skeletons here will probably count as Plaguebearers.
If those are the final paint jobs that will be produced then I see me only have to do some repaints on a few figures. Throw in some Reaper models and this army is good to go. There are also some older metal figures that are coming out in plastic such as the Almighty Crane (old metal version shown here) that could count as a Greater Demon of some sort.
So for those of you that run demon armies or have played against them, what are some good builds to run? What are, in your opinion, absolutely "must haves" in a demon army?
