1) Barghast - nasty creatures that can be giant blue goblins or big canine creatures
2) Chaos creature - large lump of constantly mutating flesh
3) Rage Demon - can't find a description in my monster manuals so I'm going to use it as a hordling from the plane of Gray wastes
4) Spined devil - again I can't find a description so another (rather horrible) miniature to use as a hordling
5) Yugoloths - two Mezzoloths (insect like) yugoloth footsoldiers and a guardian yugoloth.
