McFarlane Toys put out these three inch Spawn mini figures in 2006-7. Some of them work very well with toy soldiers. The detail is outstanding. The first series came in blind boxes. The second series came on individual blister cards. I am leaving out figures that are superhero looking or have technological weapons. There are several paint variations. It is a shame that Mcfarlane mini figure lines seem to run out of steam quickly.
They come with these big round stands.
They stand fairly well without the stands.
These demons on the right are from McFarlane's Bag o' Demons. Not sure about the lizard guy.
